[0023] In order to further understand the utility model content, characteristics and effects of the utility model, the following examples are cited, and the detailed description is as follows in conjunction with the drawings.

[0024] The structure of the utility model will be described in detail below in conjunction with the drawings.

[0025] As Figures 1 to 5 shown, the loudspeaker assembly structure provided by the embodiment of the utility model comprises a sound unit 3, further comprises: a frame 1 arranged at the lower part of the sound unit 3, the sound unit 3 is fixedly installed on the frame 1, wherein the frame 1 is separately arranged, the frame 1 comprises an upper support 101, the lower part of the upper support 101 is provided with a lower support 102, the second shock pad 5 is clamped and installed between the upper support 101 and the lower support 102; a diaphragm 2 fixedly installed on the frame 1, the inner ring of the diaphragm 2 is fixedly connected with the sound unit 3.

[0026] The above-mentioned through improving the design of the frame 1 and increasing the shock-absorbing element, aims at solving the noise problem caused by resonance in the traditional loudspeaker:

[0027] First, the sound unit 3 drives the diaphragm 2: the electric signal passes through the sound unit 3, drives the diaphragm 2 to vibrate, and generates sound waves.

[0028] The shock-absorbing part: the frame 1 is designed as two parts of the upper support 101 and the lower support 102, so that the whole structure is more flexible, can effectively isolate the vibration of the sound unit 3, reduce the transmission of vibration to the whole frame 1, thereby reducing the occurrence of resonance, and the second shock-absorbing washer 5 is clamped and installed between the upper support 101 and the lower support 102. These shock-absorbing washers are usually made of materials with good shock-absorbing performance, such as rubber, foam and sponge, which can absorb and buffer the vibration from the sound unit 3, further reduce the propagation of vibration, and can significantly reduce the resonance of the frame 1 caused by vibration, thereby reducing the generation of noise, improving the sound quality, and making the audio output clearer and more accurate.

[0029] In the embodiment, the lower part of the upper support 101 is fixedly connected with a plurality of second expansion pins 107, the second shock-absorbing washer 5 is provided with a first clamping groove 404, and the second expansion pin 107 is inserted into the first clamping groove 404. The upper support 101 is provided with a first through hole 103 for passing through a screw rod, and the lower support 102 is provided with a screw hole 104. The first through hole 103 and the screw hole 104 are correspondingly arranged, the upper support 101 is provided with three first through holes 103, and the lower support 102 is provided with three screw holes 104. The second shock-absorbing washer 5 is separately arranged, and the washer includes a first arc-shaped strip plate 401, and a second arc-shaped strip plate 402 movably contacts one side of the first arc-shaped strip plate 401. The first arc-shaped strip plate 401 and the second arc-shaped strip plate 402 are respectively provided with a limiting groove 403 for limiting the screw rod, the first clamping groove 404 is provided with two, and the two first clamping grooves 404 are arranged on the first arc-shaped strip plate 401.

[0030] The lower part of the upper support 101 is fixedly connected with a plurality of second expansion pins 107, which are inserted into the first clamping groove 404 of the second shock-absorbing washer 5. In this way, the shock-absorbing washer and the upper support 101 are reliably fixed together. However, at the same time, due to the certain expansion of the expansion pin, a certain elastic displacement can be allowed when subjected to vibration, thereby buffering the vibration and avoiding direct transmission of the vibration to the whole structure, which can effectively reduce the direct transmission of resonance and impact, and protect other elements in the device, such as the diaphragm 2 and the sound unit 3, from unnecessary vibration interference.

[0031] The upper support 101 is provided with a first through hole 103, a screw rod passes through these through holes, passes through the limiting groove 403 of the second shock-absorbing washer 5, and is fixedly connected with the screw hole 104 of the lower support 102. The first arc-shaped strip plate 401 and the second arc-shaped strip plate 402 of the second shock-absorbing washer 5 are both provided with limiting grooves 403, and when the screw rod passes through these grooves, the relative position of the upper and lower supports 102 can be fixed, and the second shock-absorbing washer 5 is prevented from being displaced laterally or axially. Necessary structural stability is provided to ensure that the support is firmly assembled while maintaining a certain flexibility to cooperate with the second shock-absorbing washer 5 to absorb excess vibration.

[0032] The second shock-absorbing washer 5 adopts a split design, including a first arc-shaped strip 401 and a second arc-shaped strip 402, which realize a certain elastic buffering effect through movable contact. The movable contact between the arc-shaped strips allows the washer to have more elastic buffering space when subjected to external vibration, which can further dissipate and buffer the vibration.

[0033] In this embodiment, the third shock-absorbing washer 6 is fixedly connected to the upper part of the upper support 101, and the diaphragm 2 is fixedly connected inside the third shock-absorbing washer 6. The sound emitting unit 3 includes a sound emitting piece 301, which is fixed on the upper support 101, and a membrane 302 is fixedly connected to the upper part of the sound emitting piece 301. The membrane 302 is located below the diaphragm 2 and cooperates with the diaphragm 2 to perform joint vibration operation.

[0034] The third shock-absorbing washer 6 is fixedly connected to the upper part of the upper support 101, and its main function is to provide additional shock-absorbing effect. By connecting the diaphragm 2 with the third shock-absorbing washer 6, the shock-absorbing washer can absorb the excess energy generated by vibration and reduce the mechanical vibration transmitted to the diaphragm 2. The sound emitting piece 301 is installed on the upper support 101, and the membrane 302 is fixedly connected to the upper part of the sound emitting piece 301. The membrane 302 is located below the diaphragm 2. The sound emitting piece 301 is driven by electrical signals to produce vibration. The membrane 302, as part of the sound emitting piece 301, directly transmits the vibration to the diaphragm 2. The close cooperation between the diaphragm 2 and the membrane 302 ensures that they can vibrate synchronously, producing more abundant and accurate sound waves. This cooperative vibration improves the acoustic performance of the loudspeaker, ensuring the accuracy of audio output.

[0035] Since the membrane 302 is located below the diaphragm 2, when the sound emitting piece 301 drives the membrane 302 to vibrate, the membrane 302 further drives the diaphragm 2 to vibrate jointly. The joint vibration design enables the diaphragm 2 to better respond to the vibration signals of the sound emitting piece 301, improving the energy transmission efficiency and enhancing the output capability of sound waves.

[0036] In this embodiment, the lower support 102 is externally provided with a second through hole 105, and the first telescopic nail 106 is inserted and installed at the lower part of the lower support 102. The first shock-absorbing washer 4 is inserted and installed on the lower support 102 through the first telescopic nail 106. The first shock-absorbing washer 4 is provided with a second clamping groove 501 corresponding to the first telescopic nail 106, and the first telescopic nail 106 is movably inserted into the second clamping groove 501.

[0037] The second through hole 105 provided on the outside of the lower support 102 provides a mounting position for the first telescopic nail 106. During installation, the first telescopic nail 106 is inserted through the second through hole 105 of the lower support 102, ensuring stable connection between the telescopic nail and the support.

[0038] The first shock absorbing washer 4 is arranged between the lower support 102 and the mounted device, and is positioned by the second clamping groove 501 corresponding to the first telescopic nail 106. After the first telescopic nail 106 is inserted into the second clamping groove 501, the first shock absorbing washer 4 is arranged to absorb vibration energy generated during operation of the device.

[0039] The working principle of the utility model is as follows:

[0040] In use, the electric signal drives the diaphragm 2 to vibrate through the sound generating unit 3, generates sound waves, and designs the frame 1 as two parts of the upper support 101 and the lower support 102, so that the whole structure is more flexible, can effectively isolate the vibration of the sound generating unit 3, reduce the transmission of vibration to the whole frame 1, thereby reducing the occurrence of resonance, and the second shock absorbing washer 5 is clamped and installed between the upper support 101 and the lower support 102. These shock absorbing washers are usually made of materials with good shock absorption performance, such as rubber, foam and sponge, and the role is to absorb and buffer the vibration from the sound generating unit 3, further reduce the propagation of vibration, can significantly reduce the resonance of the frame 1 caused by vibration, thereby reducing the generation of noise, thereby improving the sound quality, and making the audio output more clear and accurate.
