Referring to fig. 1 to 8, the present invention provides a sound generating device 100, the sound generating device 100 includes a support 80, a vibration unit 90, an elastic component 10 and a damping member 30, the elastic component 10 connects the support 80 and the vibration unit 90, and the damping member 30 is disposed on the elastic component 10.

In one embodiment, the sound generating device 100 includes a vibration unit 90, a magnetic circuit system 101, and a housing mounting and fixing the vibration unit 90 and the magnetic circuit system 101; wherein, the vibration unit 90 includes a diaphragm 91 and a voice coil 40 combined below the diaphragm 91; the magnetic circuit system 101 includes an upper magnetic conductive plate, a magnet, and a lower magnetic conductive plate, where the upper magnetic conductive plate and the lower magnetic conductive plate are magnetic conductive structures for correcting magnetic lines of force generated by the magnet, the magnetic circuit system 101 forms a magnetic gap 1011, and the voice coil 40 is disposed in the magnetic gap 1011 of the magnetic circuit system 101. The utility model discloses magnetic conduction board can be for U type structure down, including diapire and lateral wall, go up magnetic conduction board, magnet and form magnetic gap 1011 between the lateral wall of magnetic conduction board down, form relatively even magnetic field in the magnetic gap 1011, and voice coil loudspeaker voice coil 40 sets up in this magnetic gap 1011 that has relatively even magnetic field. The voice coil 40 is usually formed by winding a metal wire, and vibrates up and down by an ampere force in a magnetic field after the voice coil 40 is connected with an electric signal, the vibration direction of the voice coil 40 is represented by a vertical direction or a vertical direction, and the direction perpendicular to the vibration direction of the voice coil 40 is represented by a horizontal direction; because the vibrating diaphragm 91 and the voice coil 40 are fixedly combined into a whole through bonding and other modes, the voice coil 40 can drive the vibrating diaphragm 91 to vibrate to generate sound waves when vibrating up and down according to an electric signal.

However, since the magnetic field in the magnetic gap 1011 is only relatively uniform and not absolute, the position of the voice coil 40 may also change during the vibration of the voice coil 40, and the magnetic lines of force on the upper side of the magnetic gap 1011 are arc lines, so that the ampere force applied to the voice coil 40 is not only vertical but also includes ampere forces in other directions, which causes the voice coil 40 to easily generate non-vertical polarization during the vibration, and further affects the vibration of the diaphragm 91.

In order to prevent the occurrence of polarization in the above-described case, the elastic member 10 connecting the voice coil 40 and the holder 80 may be provided to center-support the polarization of the voice coil 40, i.e., to ensure that the voice coil 40 vibrates in the vibration direction within the magnetic gap 1011. In one embodiment, the elastic member 10 is a centering disk or a flat spring.

Referring to fig. 10, in an embodiment, the vibration unit 90 further includes a drag cup 92 disposed on the diaphragm 91, the drag cup 92 is disposed on the same side of the diaphragm 91 as the voice coil 40 and surrounds the voice coil 40, when the magnetic gap 1011 exists, the drag cup 92 is disposed outside the magnetic gap 1011, and the elastic member 10 connecting the drag cup 92 and the support 80 is also configured to center and support the polarization of the voice coil 40, i.e., to ensure that the voice coil 40 vibrates in the vibration direction in the magnetic gap 1011.

In an embodiment, the support 80 is a housing or a magnetic yoke, and since the housing can be used for bearing the speaker unit, the support 80 is configured as the housing, so that the side of the elastic component 10 departing from the vibration unit 90 can be conveniently fixed, and the centering support effect of the elastic component 10 is improved. Since most of the vibration unit 90 is close to the magnetic gap 1011, and the distance between the vibration unit and the yoke is short, one side of the elastic member 10 away from the vibration unit 90 is connected to the yoke, on one hand, the arrangement distance of the elastic member 10 can be saved, and the centering support effect of the elastic member 10 can be improved conveniently. Note that, the fixing manner of the elastic member 10 in the present embodiment includes various combinations: the elastic component 10 is connected with the voice coil 40 and the shell, the elastic component 10 is connected with the voice coil 40 and the yoke, the elastic component 10 is connected with the dragging cup 92 and the shell, and the elastic component 10 is connected with the dragging cup 92 and the yoke, so that the centering support effect of the elastic component 10 can be better ensured.

The utility model discloses sound generating mechanism 100 is through setting up support 80 and vibration unit 90, be connected one side and vibration unit 90 of elastomeric element 10 again, the opposite side is connected with support 80, further set up damping piece 30 that is located elastomeric element 10, because be provided with damping piece 30 on elastomeric element 10, elastomeric element 10 sets up the energy difference that the part of damping piece 30 and the part that does not set up damping piece 30 need produce the vibration needs of same frequency, so, can change elastomeric element 10's resonant frequency, reduce elastomeric element 10 resonant probability. Therefore, the technical scheme of the utility model can avoid elastomeric element 10 and vibration unit 90 to produce resonance, guarantee vibration unit 90's vibration orbit, guarantee sound generating mechanism 100's job stabilization nature.

In some embodiments of the present invention, the elastic member 10 includes a first deformation region and a second deformation region, the deformation amount of the first deformation region is greater than that of the second deformation region, and the damping member 30 is disposed in the first deformation region. In this embodiment, since the elastic deformation amount of a part of the elastic component 10 is larger, the part needs low energy for vibration, and is easy to resonate with the vibration unit 90 to affect the track of the vibration cabinet of the vibration unit 90, so that the damping member 30 is disposed in the first deformation region to increase the energy needed for vibration of the first deformation region, and thus, the resonant frequency of the elastic component 10 can be changed, and the probability of resonance of the elastic component 10 can be reduced. It is understood that the first deformation region and the second deformation region can be connected to each other or spaced from each other, the elastic component 10 can have a plurality of first deformation regions and a plurality of second deformation regions, and different elastic deformation amounts can be defined according to different vibration units 90 (because some vibration units 90 have high resonant frequency and some vibration units have low resonant frequency), and when the deformation amount of the deformation region is greater than the defined elastic deformation amount, the first deformation region is determined. In one embodiment, when the elastic member 10 includes the first connection portion 1 for connecting with the vibration unit 90, the second connection portion 2 for connecting with the bracket 80, and the deformation portion 3 connecting the first connection portion 1 and the second connection portion 2, the first deformation region may be understood as the deformation portion 3, and the second deformation region may be understood as the first connection portion 1 and the second connection portion 2.

In an embodiment, the elastic component 10 can have both conducting and centering functions, and can simultaneously achieve conducting functions on internal and external circuits and centering functions on vibration of the vibration unit 90, so that not only can the space in the cavity of the sound generating device 100 be saved, but also the assembly process of the sound generating device 100 is effectively simplified. And by arranging the damping member 30 between the first connection portion 1 and the second connection portion 2, the resonance frequency of the part between the first connection portion 1 and the second connection portion 2 is changed, and then the resonance frequency of the elastic member 10 is changed, so that the probability of resonance of the elastic member 10 is reduced. The resonance of the elastic component 10 is avoided, the vibration track of the vibration unit 90 is ensured, and the working stability of the sound production device 100 is ensured.
