The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, fig. 1 is a schematic external structural view of a wireless headset according to an embodiment of the present invention; fig. 2 is a schematic cross-sectional view of fig. 1.

In one embodiment, the present invention provides a wireless headset comprising ahousing 1, aheadset charging pin 2, adetection circuit board 3, and a controller.

Thecasing 1 is a main structure of the wireless earphone, and is used for mounting parts such as theearplugs 8 and protecting the internal parts. The specific shape of thehousing 1 may be set as desired, and is not particularly limited herein. Theearphone charging pin 2 is installed in thehousing 1, and it should be noted that, here, theearphone charging pin 2 is installed in thehousing 1, which means that at least a part of theearphone charging pin 2 is located inside thehousing 1 and is limited so as not to be removed from thehousing 1. Since the earphone chargingpin 2 needs to be in contact with thecartridge charging pin 03 on the charging cartridge, thecasing 1 is provided with a through hole for the earphone chargingpin 2 to pass out to be in contact with thecartridge charging pin 03, or thecartridge charging pin 03 to pass in to be in contact with the earphone chargingpin 2. Please refer to the conventional wireless headset charging structure in the prior art for the specific charging circuit setting for charging the wireless headset and the connection relationship between thecharging pin 2 of the corresponding headset in the charging box, etc. when the chargingpin 2 of the headset contacts thecharging pin 03 of the box body in the charging box, the foundation is not repeated.

Thedetection circuit board 3 is electrically connected to the controller, both of which are installed in thehousing 1. Detection circuitry has ondetection circuit board 3,earphone charging pin 2 be used for withdetection circuit board 3 contacts in order to switch on detection circuitry, specific,earphone charging pin 2 keeps anddetection circuit board 3 contacts when wireless earphone breaks away from the box that charges, disconnects withdetection circuit board 3 when wireless earphone is arranged in the box that charges to avoid wireless earphone to arrange in the box that charges when charging throughearphone charging pin 2, the adverse effect that causes detection circuitry. If the circuit setting of detection circuitry is not influenced by charging circuit, thenearphone charging pin 2 also can all keep in touch withdetection circuitry board 3 when wireless earphone is arranged in the box that charges or is deviate from by charging the box, or under the condition thatearphone charging pin 2 keeps in touch withdetection circuitry board 3 all the time, also can break off when charging circuit switches on through controller control detection circuitry to protection detection circuitry.

The detection circuit can generate a changed electric signal when a human body approaches or contacts the earphone chargingpin 2 in a conducting state. Since the wireless earphone is worn on the ear of a person when in use, a person skilled in the art can naturally think that the human body approaches to generate the changed electric signal and can eliminate the false triggering when the wireless earphone is worn on the ear of the person, for example, the distance setting of the changed electric signal generated by the approach of the human body is used. The structure of the specific detection circuit can adopt the conventional human body approach detection circuit arrangement in the prior art, for example, when a finger is close to or contacts the earphone chargingpin 2, due to the human body electric field, the finger of the user and the earphone chargingpin 2 form a coupling capacitor or directly form a current with theearphone charging pin 2, and finally form a tiny current. I.e. the varying electrical signal may specifically be a current variation, the controller monitors this variation and performs a corresponding preset operation. The varying electrical signal may also be a voltage variation, etc., depending on the arrangement of the detection circuit.

The controller is used for monitoring the changed electric signals generated by the detection circuit and executing corresponding preset operation. That is, the controller is configured to monitor the detection circuit and, when it is monitored that it generates a varying electric signal, perform a preset operation corresponding to the varying electric signal. The specific preset operation may be volume increase, volume decrease, and the like, and the corresponding relationship between the preset operation and the changed electric signal is set as required, and is not specifically limited herein. The controller may specifically be a control chip.

With the wireless earphone provided by the invention, theearphone charging pin 2 is used for contacting with the boxbody charging pin 03 in the charging box so as to charge the wireless earphone. On the other hand, when theearphone charging pin 2 contacts thedetection circuit board 3, the detection circuit is conducted, and then when a human body, such as a finger of a user, approaches or contacts theearphone charging pin 2, the detection circuit generates a changed electric signal due to the influence of an electric field of the human body, and when the controller monitors the changed electric signal generated by the detection circuit, the controller executes preset operation corresponding to the changed electric signal, such as volume increase, volume reduction and the like. To sum up,earphone charging pin 2 in this application not only is used as charging, can also be used as triggering and predetermines the operation, has realized that the function is multiplexing, and then need not to set up alone and trigger this component of predetermineeing the operation, has effectively saved the space, is favorable to wireless earphone's miniaturized design, has practiced thrift the cost simultaneously.

Further, theearphone charging pin 2 is slidably mounted in thehousing 1, themain circuit board 4 and thedetection circuit board 3 of the wireless earphone are arranged up and down along the sliding direction of theearphone charging pin 2, theearphone charging pin 2 can be kept disconnected from themain circuit board 4 by the locking device and is contacted with thedetection circuit board 3 to conduct the detection circuit, and the locking is released when the wireless earphone is placed in the charging box, so that theearphone charging pin 2 is disconnected from thedetection circuit board 3 and is contacted with themain circuit board 4 to conduct the charging circuit on themain circuit board 4. That is, the main circuit and thedetection circuit board 3 are arranged in thecasing 1, themain circuit board 4 is provided with a charging circuit, and then the charging circuit is conducted when theearphone charging pin 2 is in contact with themain circuit board 4 and the boxbody charging pin 03, so as to charge the wireless earphone. Themain circuit board 4 may be a printed circuit board in particular. Thedetection circuit board 3 may be a flexible circuit board. Themain circuit board 4 can be specifically provided with a copper sheet in a paster mode, and theearphone charging needle 2 is in contact with the copper sheet to conduct a charging circuit.

Theearphone charging pin 2 is slidably mounted on thehousing 1 and is held in a state of being in contact with thedetection circuit board 3 to conduct the detection circuit and being separated from themain circuit board 4 by a locking device. And when the wireless earphone is arranged in the charging box, the locking function of the locking device is released, theearphone charging pin 2 is separated from thedetection circuit board 3 and is in contact with themain circuit board 4 to conduct the charging loop. In the uncharged use state, theearphone charging pin 2 can keep contact with thedetection circuit board 3, the detection circuit is conducted, and theearphone charging pin 2 is only used for triggering the preset operation. In the charging state, theearphone charging pin 2 is in contact with themain circuit board 4 to conduct the charging circuit, meanwhile, the detection circuit is disconnected, and theearphone charging pin 2 only serves for charging. Through the arrangement, the detection circuit is disconnected when the charging circuit is switched on in a mechanical mode, and the influence of the charging circuit on the detection circuit can be prevented. And the mechanical mode can not fail due to circuit faults and other reasons, and the action is stable and reliable. Of course, according to actual conditions, the detection circuit can be turned off when the charging circuit is turned on by means of control of the controller and the like.

That is, theearphone charging pin 2 is held in a state of being in contact with thedetection circuit board 3 to conduct the detection circuit while being separated from themain circuit board 4 by the elastic member 5. When the wireless earphone is placed in the charging box, the chargingpin 03 of the box body is in contact with the chargingpin 2 of the earphone and drives the chargingpin 2 of the earphone to move against the restoring force of the elastic piece 5, so that the chargingpin 2 of the earphone is separated from thedetection circuit board 3 and is in contact with themain circuit board 4.

For convenience of explanation, the bottom end of the chargingpin 2 of the earphone is used for contacting themain circuit board 4, and the top end of theflange 23 is used for contacting thedetection circuit board 3. That is, thedetection circuit board 3 is located above the main circuit, and the top direction of the contact between theearphone charging pin 2 and the boxbody charging pin 03 is taken as the upper direction, and the up-down position relationship here refers to the relative position relationship, and there is no limitation of the absolute position in the wearing state. The elastic member 5 is disposed between the bottom end of theflange 23 and the case body, and compresses the elastic member 5 to generate a restoring force for pushing theearphone charging pin 2 to move upward when theearphone charging pin 2 moves downward. Theearphone charging pin 2 is held at the upper position and the tip of theflange 23 is in contact with thedetection circuit board 3 when no external force is applied. And when wireless earphone places in the box that charges corresponding to the position, the effect of the effect is exerted to earphone chargingneedle 2 to boxbody charging needle 03, andearphone charging needle 2 moves down for the top offlange 23 breaks away fromdetection circuitry board 3, and detection circuitry breaks off, andearphone charging needle 2's bottom andmain circuit board 4 contact, and charging circuitry switches on, and here elastic component 5 is in compression state. When the wireless earphone is taken out of the charging box, the chargingpin 03 of the box body does not exert the force on the chargingpin 2 of the earphone any more, the chargingpin 2 of the earphone moves upwards under the restoring force of the elastic part 5 and is in contact with the top end of theflange 23 and thedetection circuit board 3, the bottom end of the chargingpin 2 of the earphone is separated from themain circuit board 4, the detection circuit is switched on, and the charging circuit is switched off. In order to ensure the reliability of the contact of theearphone charging pin 2 with thedetection circuit board 3, it is preferable that the elastic member 5 is a compression elastic member 5.

If desired, the bottom end of the chargingpin 2 of the earphone can also be used for contacting thedetection circuit board 3, and the top end of theflange 23 can be used for contacting themain circuit board 4, i.e. thedetection circuit board 3 is located below the main circuit. The elastic member 5 is disposed between the bottom end of theflange 23 and the case body, and stretches the elastic member 5 to generate a restoring force for pushing theearphone charging pin 2 to move upward when theearphone charging pin 2 moves upward. In order to ensure the reliability of the contact of theearphone charging pin 2 with thedetection circuit board 3, it is preferable that the elastic member 5 is a tensile elastic member 5.

The elastic member 5 in the above embodiments may be a spring, or may be another elastic material or an elastic structural member capable of providing an elastic restoring force according to the requirement.

In order to improve the contact reliability of the chargingpin 2 and the detectingcircuit board 3 and the detection accuracy, please refer to fig. 3, fig. 3 is a schematic structural diagram of the charging pin of fig. 2, in which the upper end surface of theflange 23 for contacting the detectingcircuit board 3 has a plurality ofprotrusions 24 for line contact with the detectingcircuit board 3, or the bottom end of the chargingpin 2 for contacting the detectingcircuit board 3 has a plurality ofprotrusions 24 for line contact with the detectingcircuit board 3. That is, when the lower end of theearphone charging pin 2 is adapted to be in contact with themain circuit board 4 and the upper end of theflange 23 is adapted to be in contact with thetest circuit board 3, the upper end of theflange 23 has a plurality ofprotrusions 24 in line contact with thetest circuit board 3. And when the lower end of theearphone charging pin 2 is adapted to contact thedetection circuit board 3 and the upper end of theflange 23 is adapted to contact themain circuit board 4, the lower end of theearphone charging pin 2 has a plurality ofprotrusions 24 to be in line contact with thedetection circuit board 3. By the arrangement of theprotrusions 24, the surface contact is changed into the line contact, and the reliability of the contact is increased.

On the basis of the above embodiments, theearphone charging pin 2 is disposed on the microphone end face 6 opposite to theearplug 8 of the wireless earphone, that is, theearphone charging pin 2 is located on the upper end face. Theearphone charging needle 2 of the conventional wireless earphone in the prior art is positioned at the bottom, a groove is formed in the position, corresponding to the wireless earphone bearing position, of the charging box, and a boxbody charging needle 03 is arranged in the groove. However, when the wireless earphone with sweat is placed in the charging box, the sweat on the surface of the wireless earphone flows along the wireless earphone under the action of gravity, and finally accumulates at the position of the chargingneedle 03 on the bottom of the charging box to form an electrolytic cell, so that the electrolytic corrosion effect is intensified. And this application is through setting upearphone charging pin 2 on the mike terminal surface 6 relative with theearplug 8 of wireless earphone, can be close to ground with the one end ofearplug 8 when charging, and mike terminal surface 6 is kept away from ground and is placed, therefore has avoided the influence that the sweat that gathers inside the charging box charges to the earphone.

Further, theearphone charging pin 2 includes afirst charging pin 21 and asecond charging pin 22, thefirst charging pin 21 and thesecond charging pin 22 are symmetrically disposed about a center line of the mic terminal face 6, and themic hole 7 of the wireless earphone is located on the center line. Thefirst charging pin 21 and thesecond charging pin 22 are respectively used for contacting with a third charging pin and a fourth charging pin on the charging box to conduct a charging circuit. So set up, first chargingpin 21, second chargingpin 22 andmike hole 7 form the smiling face form, and the appearance is more pleasing to the eye, and then has promoted the competitiveness of product.

Specifically,casing 1 includesshell 11 andsupport 12, andshell 11 can fix on whole earphone major structure through the point is glued, sets up the mounting groove that is used for installingearphone charging needle 2 onshell 11, and the tank bottom of mounting groove has the through-hole that is used forearphone charging needle 2 to pass, andsupport 12 fixes outsideshell 11 through the point is glued, offers the through-hole that is used forearphone charging needle 2 top and boxbody charging needle 03 to contact on thesupport 12.

In case of the elastic member 5, the elastic member 5 may be disposed in the mounting groove and abut against or be fixedly connected with the groove bottom of the mounting groove. Thedetection circuit board 3 may be fixed on thesupport 12 by a double-sided adhesive tape and electrically connected with the controller. When the controller is a control chip on themain circuit board 4, the detection circuit is electrically connected with the control chip. Themain circuit board 4 may be fixed to thehousing 11 by a heat-fusible column. Theholder 12 serves as an outer surface and may in particular also serve as a decoration.

In the above embodiments, theearphone charging pin 2 includes thefirst charging pin 21 and thesecond charging pin 22, the first detection circuit and the second detection circuit are respectively provided on thedetection circuit board 3 corresponding to thefirst charging pin 21 and thesecond charging pin 22, and the controller performs the first preset operation when receiving only the changed electrical signal output by the first detection circuit; and/or the controller executes a second preset operation when only the changed electric signal output by the second detection circuit is received; and/or the controller executes a third preset operation when receiving the changed electric signal output by the first detection circuit and then receiving the changed electric signal output by the second detection circuit; and/or the controller executes a fourth preset operation when receiving the changed electric signal output by the second detection circuit firstly and then receiving the changed electric signal output by the first detection circuit.

That is, in the case that theearphone charging pin 2 includes thefirst charging pin 21 and thesecond charging pin 22, the corresponding preset operation may be triggered when only a singleearphone charging pin 2 is detected to approach or contact a human body, or when two earphone charging pins 2 are detected to approach or contact a human body successively. When a user points oneearphone charging pin 2, the corresponding detection circuit generates a changed electric signal, and the other detection circuit is unchanged. When a user slides through the surfaces of the two earphone charging pins 2, if the user slides up or down, the two detection circuits generate changed electric signals successively.

Specifically, when the controller only monitors the changed electric signal output by the first detection circuit, it determines that thefirst charging pin 21 is a single-point first charging pin, and then performs a first preset operation. When the controller only monitors the changed electric signal output by the second detection circuit, the controller judges that the signal is the single-point second chargingpin 22, and then executes a second preset operation. When the controller monitors the changed electric signal output by the first detection circuit and then the changed electric signal output by the second detection circuit, the controller determines that the electric signal is sliding and slides from thefirst charging pin 21 to thesecond charging pin 22, and then executes a third preset operation. When the controller monitors the changed electric signal output by the second detection circuit and then the changed electric signal output by the first detection circuit, the controller determines that the electric signal is sliding, and the electric signal slides from thesecond charging pin 22 to thefirst charging pin 21, and then the controller executes a fourth preset operation. Specifically, the first preset operation, the second preset operation, the third preset operation, and the fourth preset operation may be to increase the volume, decrease the volume, play the next head, and play the previous head, respectively. Of course, each preset operation can be set according to the requirement, and is not limited to the above limitation. Each preset operation is preferably set to be different operations to realize different functions, and may also be set to be partially or totally the same operation as required, and the operation may be triggered by the above-mentioned various ways.

Further, when the controller detects that thefirst charging pin 21 and thesecond charging pin 22 simultaneously have stable continuous current, the controller determines that the charging state is the charging state. The detection circuit can be further controlled to be opened according to the requirement.
