[0020] In this embodiment, with reference to Figures 1 - 4, the suspension structure of the audio speaker independent cavity includes a housing 1, a speaker cavity 2 and a speaker 3. The speaker 3 is installed in the speaker cavity 2, and the speaker cavity 2 is installed in the housing 1. It also includes a hard cavity bracket and a soft cavity bracket (elastic body). One side of the speaker cavity 2 is assembled and fixed with the hard cavity bracket. The hard cavity bracket is installed in the soft cavity bracket, and the soft cavity bracket is assembled and fixed with the housing 1. The speaker 3 is installed in the speaker cavity 2 through the hard cavity bracket. The other side of the speaker cavity 2 is assembled and fixed with the housing 1 through a soft connecting piece. Through the cooperation of the soft connecting piece and the soft cavity bracket, a suspended soft connection structure is formed between the speaker cavity 2 and the housing 1 without rigid contact.

[0021] The hard cavity bracket includes a first bracket 4 and a second bracket 5, and the soft cavity bracket includes a third bracket 6. The first bracket 4 is fixed at the front end of the speaker cavity 2. The second bracket 5 is nested in the third bracket 6. The second bracket 5 is sleeved outside the first bracket 4 through the third bracket 6 to form a suspended fixation of the first bracket 4 without rigid contact. The third bracket 6 is assembled and fixed with the front end of the housing 1, which is an elastic contact.

[0022] The second bracket 5 is sleeved outside the first bracket 4. There is a gap 9 between the first bracket 4 and the second bracket 5. The third bracket 6 is wrapped outside the first bracket 4 and the second bracket 5 through a soft rubber sleeve injection molding method and is embedded in the gap 9 between the first bracket 4 and the second bracket 5, so that the second bracket 5 and the first bracket 4 form a soft connection assembly structure.

[0023] The soft connecting piece is a flexible rubber plug 7. The tail end of the speaker cavity 2 is connected and fixed with the tail of the housing 1 through several (such as four) rubber plugs 7, which makes the speaker cavity 2 float in the housing 1.

[0024] Screw holes 8 are provided on both the third bracket 6 and the second bracket 5. Screws are sequentially passed through the screw holes 8 of the third bracket 6 and the second bracket 5 and screwed into the housing, so that the second bracket 5 is locked and fixed with the housing 1 through the third bracket 6.

[0025] The first bracket 4 is locked and fixed at the front end of the speaker cavity 2 through screws.

[0026] The first bracket 4 and the second bracket 5 are made of hard plastic, such as ABS, and the third bracket 6 is made of soft plastic, such as TPR or silicone.

[0027] Refer to Figure 5 is the frequency response curve diagram of the present invention, which shows that when the volume output is different, the frequency response curve is overly smooth and the sound is not compressed.

[0028] Refer to Figure 6 is the harmonic distortion degree curve diagram of the present invention, which shows that when the volume output is different, the distortion curve is getting lower and the sound is getting cleaner.

[0029] Refer to Figure 7 This is a comparative curve graph of the harmonic distortion of the present utility model and that of the traditional cavity with hard connection. Among them, the blue color represents the traditional audio structure, that is, the speaker cavity adopts a hard connection structure without a suspension structure. The green color represents the audio structure of the present utility model, and the speaker cavity adopts a soft connection with a suspension structure. By comparing the curves of the two, it can be seen that after the speaker cavity adopts the suspension structure design, the distortion of the audio has been significantly improved, the sound is clean and clear, and the acoustic effect is better than that of the traditional hard connection structure.
