本发明涉及骨传导技术领域，尤其涉及一种骨气复合发声装置及可穿戴设备。The invention relates to the technical field of bone conduction, in particular to a bone-energy composite sounding device and a wearable device.
背景技术Background technique
骨传导耳机能将电信号转换为机械振动信号，并将机械振动信号通过人体组织及骨骼传入人体的听觉神经，使佩戴者听到声音。目前，有一些骨传导耳机的振子上设置有振膜，振子振动带动振膜振动，振膜鼓动空气发声。这样，骨传导耳机既可以与人脸贴合实现骨传导传声，还可以实现气传导传声，能够获得更大的响度。Bone conduction earphones can convert electrical signals into mechanical vibration signals, and transmit the mechanical vibration signals to the auditory nerve of the human body through human tissues and bones, so that the wearer can hear the sound. At present, some bone conduction earphones are provided with a diaphragm on the vibrator, the vibration of the vibrator drives the vibration of the diaphragm, and the diaphragm agitates the air to produce sound. In this way, bone conduction earphones can not only fit the face to realize bone conduction sound transmission, but also realize air conduction sound transmission, which can obtain greater loudness.
目前，振膜通常连接在振子振动方向的一端，由振子带动沿着振动方向振动，为了使得出声方向靠近人耳，需要在耳机头的侧面开设出声孔，出声孔的方向与振动方向一般是垂直的，气流需要转变方向之后从出声孔发出，这也就使得声波能量的损失比较大，对振子能量的利用效率较低。At present, the diaphragm is usually connected to one end of the vibration direction of the vibrator, and is driven by the vibrator to vibrate along the vibration direction. In order to make the sound output direction close to the human ear, it is necessary to open a sound hole on the side of the headphone head. The direction of the sound hole is consistent with the vibration direction. Generally, it is vertical, and the airflow needs to change direction to be sent out from the sound hole, which causes a relatively large loss of sound wave energy and a low utilization efficiency of the vibrator energy.
因此，有必要对现有技术予以改良以克服现有技术中的所述缺陷。Therefore, it is necessary to improve the prior art to overcome the defects in the prior art.

The occurrences of this phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is understood explicitly and implicitly by those skilled in the art that the embodiments described herein can be combined with other embodiments.
如图1至图5所示，对应于本发明一种较佳实施例的骨气复合发声装置，其包括外壳1、定子组件2、振动组件3、振膜4和弹性件5。As shown in FIG. 1 to FIG. 5 , corresponding to a preferred embodiment of the bone-qi composite sounding device of the present invention, it includes a housing 1 , a stator assembly 2 , a vibrating assembly 3 , a diaphragm 4 and an elastic member 5 .
如图2所示，外壳1包括出声孔10和用于向皮肤传递振动的第一表面11，通常的，外壳1包括面板12，面板12朝向人体皮肤的表面为第一表面11。As shown in FIG. 2 , the housing 1 includes a sound outlet 10 and a first surface 11 for transmitting vibrations to the skin. Generally, the housing 1 includes a panel 12 , and the surface of the panel 12 facing the human skin is the first surface 11 .
进一步参考图3和图4，振膜4连接在振动组件3和外壳1之间，且与出声孔10对应设置。当振动组件3振动时，其带动振膜4振动，进而使得振膜4鼓动空气发声，声音能够从出声孔10发出。振膜4可以设置成封住出声孔10，也可以设置成不封住出声孔10，例如与出声孔10之间留有缝隙，又如直接在振膜4上设置小孔。一般的，当外壳1作为可穿戴设备最外侧的壳体时，此时由于出声孔10直接与外界接触，因此，振膜4通常需要设置成封住出声孔10，以起到防水防尘的效果。当骨气复合发声装置作为整体装入可穿戴设备的壳体内时，由于外壳1不与外界直接接触，此时，振膜4与出声孔10之间可以留有间隙，而在可穿戴设备的壳体上设置与出声孔10对应的孔位，并可在壳体上增设防护结构。Further referring to FIG. 3 and FIG. 4 , the diaphragm 4 is connected between the vibrating assembly 3 and the casing 1 , and is arranged corresponding to the sound outlet 10 . When the vibrating component 3 vibrates, it drives the vibrating membrane 4 to vibrate, and then the vibrating membrane 4 agitates air to produce sound, and the sound can be emitted from the sound outlet 10 . The diaphragm 4 can be set to seal the sound outlet 10 , or it can be arranged not to seal the sound outlet 10 , for example, there is a gap between the diaphragm 4 and the sound outlet 10 , or a small hole is directly arranged on the diaphragm 4 . Generally, when the shell 1 is used as the outermost shell of the wearable device, since the sound hole 10 is in direct contact with the outside world, the vibrating membrane 4 usually needs to be set to seal the sound hole 10 to play a waterproof and waterproof role. dust effect. When the bone-energy composite sounding device is packed into the shell of the wearable device as a whole, since the shell 1 is not in direct contact with the outside world, there may be a gap between the diaphragm 4 and the sound outlet 10, and the shell 1 of the wearable device Holes corresponding to the sound holes 10 are provided on the casing, and a protective structure can be added on the casing.
第一表面11可以直接与人体皮肤接触或者间接与人体皮肤接触，例如在第一表面11设置软质层，通过软质层与人体皮肤接触。当振动组件3在外壳1内振动时，其振动通过弹性件5传递至面板12，并通过第一表面11传递给人体皮肤。The first surface 11 may directly contact the human skin or indirectly contact the human skin, for example, a soft layer is provided on the first surface 11, and the first surface 11 contacts the human skin through the soft layer. When the vibrating assembly 3 vibrates in the housing 1 , its vibration is transmitted to the panel 12 through the elastic member 5 , and then transmitted to the human skin through the first surface 11 .
定子组件2设于外壳1内，且与外壳1相对固定，其可以与外壳1直接连接，也可以通过其他零件与外壳1间接连接。The stator assembly 2 is arranged in the casing 1 and is relatively fixed to the casing 1. It can be directly connected to the casing 1 or indirectly connected to the casing 1 through other parts.
如图4和图5所示，振动组件3设于外壳1内，其能够在定子组件2的驱动下沿着振动轴线3a振动，优选的，定子组件2通过电磁力驱动振动组件3沿着振动轴线3a振动。弹性件5连接在振动组件3和外壳1之间，能够将振动组件3的振动传递至外壳1，并通过弹力驱动振动组件3复位。可以理解的是，振动组件3的振动为往复振动，因此，其沿着振动轴线3a具有两个相反的振动方向，为叙述和示意方便，附图中仅示出了一个方向。As shown in Figure 4 and Figure 5, the vibrating assembly 3 is arranged in the housing 1, which can vibrate along the vibration axis 3a under the drive of the stator assembly 2, preferably, the stator assembly 2 drives the vibrating assembly 3 to vibrate along the Axis 3a vibrates. The elastic member 5 is connected between the vibrating component 3 and the casing 1, and can transmit the vibration of the vibrating component 3 to the casing 1, and drive the vibrating component 3 to reset by elastic force. It can be understood that the vibration of the vibrating assembly 3 is a reciprocating vibration, therefore, it has two opposite vibration directions along the vibration axis 3a, and for the convenience of description and illustration, only one direction is shown in the drawings.
振动轴线3a具有相互垂直的第一分量3b和第二分量3c，其中，第一分量3b与出声孔10的轴线100平行或重合，第二分量3c指向第一表面11。这样，振动组件3振动后，其沿着第一分量3b的振动能够驱动振膜4振动，从而鼓动空气发声，而其沿着第二分量3c的振动能够驱动第一表面11振动，当第一表面11与人体皮肤接触时，振动将被传递至人体，从而使人通过骨导的方式听到声音。由于振膜4振动后，气流能够直接从出声孔10发出，无需改变方向或者经过较长的传递路径，因此其能量损耗小，发声效率更高。另外，由于气流能够直接传递至外壳1外部，不会在外壳1内出现气流紊乱，有利于提高发声质量。The vibration axis 3a has a first component 3b and a second component 3c perpendicular to each other, wherein the first component 3b is parallel or coincident with the axis 100 of the sound outlet 10 , and the second component 3c points to the first surface 11 . In this way, after the vibrating component 3 vibrates, its vibration along the first component 3b can drive the diaphragm 4 to vibrate, thereby agitating the air to make sound, and its vibration along the second component 3c can drive the first surface 11 to vibrate, when the first When the surface 11 is in contact with human skin, the vibration will be transmitted to the human body, so that the human can hear sound through bone conduction. Since the diaphragm 4 vibrates, the airflow can be sent directly from the sound outlet 10 without changing the direction or passing through a long transmission path, so the energy loss is small and the sound generation efficiency is higher. In addition, since the airflow can be directly transmitted to the outside of the casing 1 , there will be no airflow turbulence in the casing 1 , which is beneficial to improve the sound quality.
作为一种优选的实施方式，振动组件3包括导磁芯30和环绕在导磁芯30外周的线圈31，定子组件2与导磁芯30的端部相对间隔设置。线圈31通电后，导磁芯30的两端部（沿着线圈31轴线方向的两端分别为第一端部300和第二端部301）被极化成N极或者S极。可以理解的是，同一时刻，第一端部300和第二端部301的极性可以是相同的，也可以是相反的。在一些实施例中，如图6所示，线圈31的数量为一个，此时，当线圈31通电后，导磁芯30的第一端部300和第二端部301的极性相反，且随着通入线圈31内的电流方向的变化，第一端部300和第二端部301的极性也会变化。在一些实施例中，线圈31的数量为两个或两个以上，图7示出的实施例中，线圈31的数量为两个，且同一时刻通入两个线圈31内的电流方向相反，此时，第一端部300和第二端部301的极性始终相同。As a preferred embodiment, the vibrating assembly 3 includes a magnetically permeable core 30 and a coil 31 surrounding the outer periphery of the magnetically permeable core 30 , and the stator assembly 2 is arranged at a distance from the end of the magnetically permeable core 30 . After the coil 31 is energized, the two ends of the magnetically permeable core 30 (the two ends along the axis of the coil 31 are respectively the first end 300 and the second end 301 ) are polarized into N poles or S poles. It can be understood that at the same moment, the polarities of the first end portion 300 and the second end portion 301 may be the same or opposite. In some embodiments, as shown in FIG. 6 , the number of coils 31 is one. At this time, when the coil 31 is energized, the polarities of the first end 300 and the second end 301 of the magnetically permeable core 30 are opposite, and As the direction of the current flowing into the coil 31 changes, the polarities of the first end portion 300 and the second end portion 301 also change. In some embodiments, there are two or more coils 31. In the embodiment shown in FIG. At this time, the polarities of the first end portion 300 and the second end portion 301 are always the same.
定子组件2包括与导磁芯30的同一端部相对设置的第一磁极20和第二磁极21，第一磁极20和第二磁极21沿着振动轴线3a布置，且两者的极性相反，这样，导磁芯30的端部一侧受到吸引力，另一侧受到排斥力，形成驱使其沿着振动轴线3a振动的驱动力。The stator assembly 2 includes a first magnetic pole 20 and a second magnetic pole 21 disposed opposite to the same end of the magnetically permeable core 30, the first magnetic pole 20 and the second magnetic pole 21 are arranged along the vibration axis 3a, and the polarities of the two are opposite, In this way, one side of the end of the magnetic permeable core 30 receives an attractive force, and the other side receives a repulsive force, forming a driving force to drive it to vibrate along the vibration axis 3a.
定子组件2的数量可以是一组或者两组，优选的，骨气复合发声装置包括两组定子组件2，两组定子组件2分别与导磁芯30的两端部相对间隔设置，这样，导磁芯30的两端受力更为均衡，且沿着线圈31和导磁芯30轴线方向的力（图4中上下方向）被抵消，导磁芯30能够更好的沿着振动轴线3a振动。The number of stator assemblies 2 can be one group or two groups. Preferably, the bone-energy composite sounding device includes two groups of stator assemblies 2, and the two groups of stator assemblies 2 are respectively spaced apart from the two ends of the magnetically permeable core 30, so that the magnetically conductive The force on both ends of the core 30 is more balanced, and the forces along the axis direction of the coil 31 and the magnetic permeable core 30 (up and down directions in FIG. 4 ) are offset, and the magnetic permeable core 30 can better vibrate along the vibration axis 3a.
优选的，第一磁极20和第二磁极21朝向导磁芯30的端面的几何中心的连线24与振动轴线3a平行，这样，以第一端部300为例，在水平方向上，第一磁极20对第一端部300的磁力和第二磁极21对第一端部300的磁力的合力的方向大致与连线24的方向一致，可以高效地驱动导磁芯30沿着振动轴线3a振动。参考图9和图10，图9和图10是应用有图8所示的骨传导发声装置的两个垂直方向的剖视图，图9示出的情形中，第一端部300和第二端部301分别被极化为N极和S极，第一端部300上方的两个磁极从左至右分别为N极和S极，第二端部301下方的两个磁极分别为S极和N极，上下的两个第一磁极20的极性相反，两个第二磁极21的极性也相反，这样，定子组件2将对导磁芯30的两端产生向右（即第一分量3b方向）的水平分力。同时，参考图10，在另一视向上，第一端部300上方的两个磁极从左至右分别为N极和S极，第二端部301下方的两个磁极从左至右分别为S极和N极，定子组件2将对导磁芯30的两端产生向右（即第二分量3c方向）的水平分力，进而使得振动组件3沿着振动方向3a振动。Preferably, the line 24 of the first magnetic pole 20 and the second magnetic pole 21 toward the geometric center of the end face of the magnetic conductor core 30 is parallel to the vibration axis 3a, so that, taking the first end 300 as an example, in the horizontal direction, the first The direction of the resultant force of the magnetic force of the magnetic pole 20 on the first end 300 and the magnetic force of the second magnetic pole 21 on the first end 300 is roughly the same as the direction of the connection line 24, which can efficiently drive the magnetic core 30 to vibrate along the vibration axis 3a . Referring to Fig. 9 and Fig. 10, Fig. 9 and Fig. 10 are cross-sectional views in two vertical directions where the bone conduction sound generating device shown in Fig. 8 is applied. In the situation shown in Fig. 9, the first end 300 and the second end 301 are respectively polarized as N pole and S pole, the two magnetic poles above the first end 300 are respectively N pole and S pole from left to right, and the two magnetic poles below the second end 301 are respectively S pole and N pole. polarity, the polarity of the upper and lower two first magnetic poles 20 is opposite, and the polarity of the two second magnetic poles 21 is also opposite. In this way, the stator assembly 2 will produce a rightward direction (that is, the first component 3b) to the two ends of the magnetic permeable core 30 direction) horizontal force component. At the same time, referring to FIG. 10 , in another viewing direction, the two magnetic poles above the first end 300 are N poles and S poles from left to right, and the two magnetic poles below the second end 301 are respectively N poles and S poles from left to right. With the S pole and N pole, the stator assembly 2 will generate a horizontal component force to the right (that is, the direction of the second component 3 c ) on both ends of the magnetic permeable core 30 , and then make the vibrating assembly 3 vibrate along the vibration direction 3 a.
可以理解的是，在导磁芯30两端被极化成相同的极性时，上下的两个第一磁极20极性相同，上下的两个第二磁极21的极性相同，优选上下的两组定子组件2对称设置，以使得两组定子组件2产生的水平方向的驱动力方向一致。It can be understood that when both ends of the magnetic permeable core 30 are polarized to the same polarity, the polarities of the upper and lower first magnetic poles 20 are the same, and the polarities of the upper and lower second magnetic poles 21 are the same. The sets of stator assemblies 2 are arranged symmetrically, so that the directions of the driving forces in the horizontal direction generated by the two sets of stator assemblies 2 are consistent.

In this way, the position of the force exerted by the first magnetic pole 20 on the first end 300 is biased to the lower right, and the position of the force exerted by the second magnetic pole 21 on the first end 300 is biased to the upper left, so that the vibrating assembly 3 can be driven to vibrate along the Axis 3a vibrates.
