Implementation mode one
Referring to fig. 1-3, the present invention provides a sound production device 100, which includes a frame 1, a vibration system 2, and a magnetic circuit system 3 having a magnetic gap 30. The vibration system 2 and the magnetic circuit system 3 are respectively and fixedly supported on the basin frame 1, and the magnetic circuit system 3 is used for driving the vibration system 2 to vibrate and sound.
It should be noted that the specific structural form of the frame 1 is not limited, and it can be specifically set according to the actual use situation, for example, in the present embodiment, the frame 1 includes a bottom plate 11, an outer wall 12 bent and extended from the periphery of the outer side of the bottom plate 11, and an inner wall 13 bent and extended from the inner side of the bottom plate 11, and the outer wall 12 is disposed around the inner wall 13 and spaced from each other; of course, in practical applications, it is also possible to provide the basin stand with only the bottom plate and the outer wall.
The inner wall 13 encloses an accommodating space 10; the inner wall 13 is provided with through openings 131 extending therethrough, the through openings 131 extending in the vibration direction of the vibration system 2.
The vibration system 2 includes: a diaphragm 21, a voice coil support 22, a voice coil 23, and an auxiliary diaphragm 24.
The diaphragm 21 includes a vibration portion 211, a bent portion 212 bent and extended from a peripheral edge of the vibration portion 211, and a fixing portion 213 bent and extended from the bent portion 212 and fixed to the frame 1.
In the present embodiment, specifically, the vibration portion 211 radiates sound waves to generate sound when vibrating. Specifically, the vibrating portion 211 has a ring shape.
The hinge portion 212 is used for improving elastic support and vibration amplitude when the vibration portion 211 vibrates, and includes a first hinge portion 2121 and a second hinge portion 2122 which are bent and extended from two opposite sides of the vibration portion 211 and are annular. The first collar portion 2121 is disposed around the second collar portion 2122 and spaced apart from each other.
The fixing portion 213 is used for fixing the diaphragm 21 to the frame 1, and includes a first fixing portion 2131 bent and extended from a side of the first collar portion 2121 away from the vibrating portion 211 and a second fixing portion 2132 bent and extended from a side of the second collar portion 2122 away from the vibrating portion 211, and both the first fixing portion 2131 and the second fixing portion 2132 are annular; the first fixing portion 2131 is fixed to the outer wall 12, and the second fixing portion 2132 is fixed to the magnetic circuit system 3 so as to be away from the vibrating direction of the diaphragm 21.
In the above structure, the first collar part 2121 and the second collar part 2122 are arranged, so that the vibrating diaphragm 21 has a double-collar structure, the double-collar structure effectively improves the rigidity of the vibrating diaphragm 21, and the problem that the vibrating diaphragm is damaged due to too large vibration amplitude in the vibration process is avoided, so that the vibration reliability of the vibration system 2 is high.
One end of the voice coil bobbin 22 is fixed to the vibrating portion 211, and the other end of the voice coil bobbin 22 extends into the magnetic gap 30 through the through hole 131.
In this embodiment, the voice coil support 22 includes a ring-shaped flat wall 221 and an extension wall 222, the flat wall 221 is attached to one side of the vibration portion 211 close to the magnetic circuit system 3 to serve as a dome structure of the diaphragm 21, and the extension wall 222 is bent and extended from the flat wall 221 to a direction away from the diaphragm 21 to be connected with the voice coil 23 and support the voice coil 23.
Preferably, the vibration portion 211 is provided with a through hole 2111 extending therethrough, and one end of the voice coil bobbin 22 connected to the vibration portion 211 completely covers the through hole 2111, i.e., the flat plate wall 221 completely covers the through hole 2111. Compared with the vibration part 211, the flat wall 221 is made of a rigid material, which is beneficial to improving the high-frequency acoustic performance of the sound production device 100, and the thickness of the diaphragm 21 can be reduced to a certain extent by the arrangement of the through holes 2111, so that the vibration space of the vibration part 211 is effectively increased.
The voice coil 23 is inserted into the magnetic gap 30 and is fixedly connected to an end of the voice coil bracket 22 away from the vibrating portion 211, that is, the voice coil 23 is fixedly connected to the extending wall 222. The voice coil 23 drives the extension wall 222 to vibrate to drive the flat wall 221 to vibrate, so as to drive the vibration portion 211 to vibrate and generate sound.
It should be noted that, because the flat wall 221 of the voice coil bracket 22 serves as a top ball structure of the diaphragm 21 to radiate sound waves, and the extension portion 222 is used to fix the voice coil 23, that is, the voice coil bracket 22 and the diaphragm 21 form an integrated structure, the fitting error of assembly between parts is reduced, the acoustic performance is improved, the assembly process is simplified, and the production efficiency is improved.

The second extension wall 2222 abuts against the outside of the voice coil 23 and forms a fixed connection. The structure realizes that the extension wall 222 of the voice coil bracket 22 is bonded from the outer side of the voice coil 23 to form a support for the voice coil 23, the structural design is more flexible for controlling the magnetic gap 30, and the design of the whole structure of the sound device 100 is more convenient.
