Abstract

The utility model relates to a temperature and pressure double-control energy-saving earphone, which can automatically stop music play when an earplug is disengaged from an ear so as to achieve the goal of saving energy. The temperature and pressure double-control energy-saving earphone is characterized in that a temperature sensor and a pressure sensor are installed in a position where the earplug contacts with an external auditory meatus, and the sensors receive environmental information to control play and stop of a player. The temperature and pressure double-control energy-saving earphone can prevent that a mobile player plays music for a long time under the condition that nobody is aware, saves energy, can protect hardware, and is simple in structure.

Description

The warm-pressing double-control energy saving headset

Technical field

The utility model belongs to the novel electron articles for use, energy-conservation and hommization.

Technical background

Advocate youth at this and advocate in the new trend of vigor, listening to the music with earplug is a kind of popular amusement phenomenon, also becomes a kind of important means that people are alleviated life stress.But we mostly had such experience: when our player is opened, if earphone falls down or has forgotten to turn off player when not listening to the music from ear, music also or normal play, even we at this time do not enjoy beautiful music, battery is also still in continuous consumes power, especially many young men like listening to the music or English Listening Comprehension before sleeping, but unconsciously fall asleep, until battery electric quantity exhausts, like this, mobile phone has been shortened in continuous discharge greatly for a long time, MP3, the battery life of the mobile playback equipment such as MP4, more seriously, the music of ultra-long time has fatal damage to the hardware of player itself, as easy as rolling off a logly causes the overheated of hardware to burn out.

The utility model content

The purpose of this utility model is to solve earphone disengaging ear and still continues later on music playing volume problem, plays the effect of the hardware such as protection battery.Main execution mode of the present utility model: inner at earphone, temperature sensor (1), pressure sensor (6) are connected with voice coil loudspeaker voice coil (11), in circuit, be connected in series a temperature sensor (1) and a pressure sensor (6), foam encasement (2) has dough kneading sensation, and phonate hole (3) is netted aperture; Voice coil suspension (5), brandreth (7), shell (12) are all fixing, (9) unshakable in one's determination pass magnet (8), voice coil loudspeaker voice coil (11) one ends connect cone (4), lead-in wire (10) is connected in series voice coil loudspeaker voice coil (11), temperature sensor (1) and pressure sensor (6), and circuit need access line traffic control equipment (13).

The utility model is simple in structure, simple and easy, the easy operating of making not only, can play the effect of protection hardware, and is very practical, and can play the effect of energy-conserving and environment-protective, suitable for large-scale promotion.

Embodiment

As shown in Figure 1, can directly contact position (Fig. 1) mounting temperature sensor (1) (high sensitive negative tempperature coefficient thermistor) of skin of external auditory canal at earplug, temperature sensor (1) is connected with voice coil loudspeaker voice coil (11), and at line traffic control equipment (13) electric current lock value is set, only have when temperature reaches 30 degrees centigrade, electric current by earphone reaches lock value electric current (this electric current is very little, generally can only make earphone send faint sound); Otherwise, if temperature sensor (1) ambient temperature is lower than 30 degrees centigrade (for example earphone and ear disengage), electric current drops to below the lock value, and line traffic control equipment (13) sends the order that stops to play to mobile playback equipment, and earphone just stops music playing.

Certainly, consider that summer is may temperature higher, even earplug breaks away from ear, the residing ambient temperature of temperature sensor (1) is still more than 30 degrees centigrade, equipment still can work on, and considers in view of this, and we settle pressure sensor (6) (presser sensor resistance) again at earplug edge (Fig. 1), because when earplug plug to external auditory meatus the time, earplug itself will inevitably bear pressure.Only have when earphone plug arrives ear, pressure sensor (6) is subject to the pressure from external auditory meatus, just allows to pass through more than or equal to the electric current of lock value.

Foam encasement (2) has dough kneading sensation, can not injure skin; The position that phonate hole (3) sends for sound is netted aperture; Voice coil suspension (5), brandreth (7), shell (12) all have fixed function, (9) unshakable in one's determination pass magnet (8), voice coil loudspeaker voice coil (11) one ends connect cone (4), voice coil loudspeaker voice coil (11) drives cone (4) vibration sounding, lead-in wire (10) connects voice coil loudspeaker voice coil (11), temperature sensor (1) and pressure sensor (6), and circuit need access line traffic control equipment (13).

Two transducers are at the earplug plug during to the ear music, all will with the external auditory meatus close contact, consider the external structure of people's ear, two transducers all should be at the top of earplug lateral edge, be convenient to like this contact, they are arranged side by side, but temperature sensor (1) and pressure sensor (6) place the outer ledge top of earplug when requiring to use, temperature sensor (1) is near sounding face, pressure sensor (6) is convenient to the normal operation of temperature sensor (1) and pressure sensor (6) like this away from sounding face.

Pressure sensor (6) connect with temperature sensor (1) (Fig. 1), temperature sensor (1) and the external line traffic control equipment of pressure sensor (6) (13), join with player again, thus the broadcast by control circuit size of current control player or stop.Both either party environment of living in are undesirable, and line traffic control equipment namely sends the order that stops to play to mobile playback equipment, and earphone just quits work.So just can play the effect of duplicate protection.

Claims (3)

1. warm-pressing double-control energy saving headset, inner at earphone, temperature sensor (1), pressure sensor (6) are connected with voice coil loudspeaker voice coil (11), it is characterized in that: in circuit, be connected in series a temperature sensor (1) and a pressure sensor (6), foam encasement (2) has dough kneading sensation, and phonate hole (3) is netted aperture; Voice coil suspension (5), brandreth (7), shell (12) are all fixing, (9) unshakable in one's determination pass magnet (8), voice coil loudspeaker voice coil (11) one ends connect cone (4), lead-in wire (10) is connected in series voice coil loudspeaker voice coil (11), temperature sensor (1) and pressure sensor (6), and circuit need access line traffic control equipment (13).

2. warm-pressing double-control energy saving headset according to claim 1, it is characterized in that: temperature sensor (1) and pressure sensor (6) place the outer ledge top of earplug, and temperature sensor is near sounding face, and pressure sensor is away from sounding face.

3. warm-pressing double-control energy saving headset according to claim 1 and 2, it is characterized in that: temperature sensor (1) and the external line traffic control equipment of pressure sensor (6) (13), join with player again, thus the broadcast by control circuit size of current control player or stop.
