To achieve a certain acoustic effect, a corresponding speaker structure needs to be set on the temple 1, and its speaker structure is as follows: Figure 1 As shown, the temple 1 needs to be designed with a front acoustic cavity 11, a rear acoustic cavity 13, a sound outlet 12, and a sound vent 14 on both the front and rear sides of the speaker module 2. The front acoustic cavity 11 is connected to the sound outlet 12, and the rear acoustic cavity 13 is connected to the sound vent 14. The front acoustic cavity 11 is the cavity where the diaphragm surface 21 of the speaker module 2 is located. Currently, the speaker module 2 is installed on the temple 1 at a sloping bottom position. Figure 3 In position A, to achieve a fixed seal for the speaker module 2 and to match the design of the temple 1, the sound outlet 12 on the temple 1 forms a long and flat tunnel structure, such as... Figure 2 As shown, this tunnel structure significantly weakens the high-frequency resonance peaks in acoustics, resulting in insufficient acoustic performance of the product. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a glasses display device that can improve the sound outlet structure, expand the front sound cavity, increase the sound resonance frequency of the whole device in the high frequency band, and improve its acoustic performance.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A pair of eyeglasses display devices includes a frame and temples mounted on the left and right sides of the frame. A speaker module is mounted on the temple, and a sound outlet is formed on the housing of the temple. The speaker module is sealed and fixed to the housing by a speaker bracket. A clearance space is formed between the side of the speaker bracket near the sound outlet and the housing. The clearance space is directly connected to the sound outlet. The clearance space and the space between the diaphragm surface of the speaker module and the housing together form a front sound cavity.

[0006] Furthermore, the speaker bracket has a square ring structure, and the speaker bracket includes a gate-shaped support part and a clearance part connected to the support part near the sound outlet. The clearance part is bent away from the diaphragm surface, and the clearance space is formed between the clearance part and the housing.

[0007] Furthermore, a support surface is provided on the inner side of the support portion, and the speaker module is sealed to the support surface with adhesive.

[0008] Furthermore, a positioning structure is provided on the housing located around the horn bracket.

[0009] Furthermore, the positioning structure consists of the inner walls on the upper and lower sides of the housing and two straight positioning baffles located on the front and rear sides of the speaker bracket, respectively.

[0010] Furthermore, the edge of the avoidance portion near the sound outlet is a contoured structure adapted to the inner wall structure of the housing.

[0011] Furthermore, the avoidance part has a triangular structure, and one side of the avoidance part abuts against one of the straight positioning retaining walls.

[0012] Furthermore, the surface of the speaker bracket is provided with an adhesive coating surface for adhesive sealing with the housing. The adhesive coating surface includes the bottom surface of the support portion and the side of the clearance portion near the sound outlet and the side of the clearance portion near the straight positioning barrier.

[0013] Furthermore, a groove is formed on the housing at a position opposite to the diaphragm surface and the clearance portion.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] In the eyeglass display device disclosed in this utility model, the speaker bracket supports and fixes the speaker module, and an clearance space is formed between the speaker bracket and the housing. The clearance space and the space between the speaker module diaphragm surface and the housing together form the front acoustic cavity. The front acoustic cavity is directly connected to the sound outlet. On the one hand, it avoids the adverse effects of the tunnel structure on high-frequency acoustic vibration in the prior art. On the other hand, the front acoustic cavity is not limited by the positioning of the speaker module and is large enough. After the front acoustic cavity is enlarged, the sound quality of the product can be effectively improved. This structure is suitable for the application of miniaturized AR and MR devices.

[0016] In this invention, the positioning structure provided on the housing can effectively support and fix the speaker bracket. Through the sealing fit between the housing and the speaker bracket, and the sealing fit between the speaker bracket and the speaker module, the speaker module can be sealed and fixed on the housing.

[0031] like Figure 3 , Figure 4 and Figure 7 As shown, an eyeglass display device includes a frame 3 and temples 4 mounted on the left and right sides of the frame 3. A speaker module 43 is mounted on the temples 4. A sound outlet 413 is provided on the housing 41 of the temples 4. The speaker module 43 is sealed and fixed to the housing 41 by a speaker bracket 42. A clearance space is formed between the side of the speaker bracket 42 near the sound outlet 413 and the housing 41. The clearance space is directly connected to the sound outlet 413. The clearance space and the space between the diaphragm surface of the speaker module 43 and the housing 41 together form a front sound cavity 44.

[0032] The temple 4 consists of an inner shell and an outer shell. The speaker module 43 can be installed in the inner shell or the outer shell as needed. In this application, the speaker module 43 is specifically installed in the inner shell.

[0033] like Figure 5 and Figure 6 As shown, the speaker bracket 42 has a square ring structure. The speaker bracket 42 includes a gate-shaped support portion 421 and a clearance portion 423 connected to the support portion 421 near the sound outlet 413. The clearance portion 423 is bent away from the diaphragm surface, and the clearance space is formed between the clearance portion 423 and the housing 41. A support surface 422 is provided on the inner side of the support portion 421, and the speaker module 43 is glued and sealed to the support surface 422.

[0034] like Figure 7 As shown, a groove 412 is formed on the housing 41 at a position opposite to the diaphragm surface and the clearance portion 423. The front acoustic cavity 44 is formed between the groove 412, the diaphragm surface of the speaker module 43, the clearance portion 423, and the lower inner wall of the housing 41.

[0035] like Figure 7 and Figure 8 As shown, a positioning structure is provided on the housing 41 located around the speaker bracket 42. The positioning structure consists of the inner walls on the upper and lower sides of the housing 41 and two straight positioning baffles 411 located on the front and rear sides of the speaker bracket 42, respectively.

[0036] like Figure 5 and Figure 8 As shown, the edge of the clearance portion 423 near the sound outlet 413 is a contoured structure adapted to the inner wall structure of the housing 41. In this application, the clearance portion 423 has a triangular structure, with one side of the clearance portion 423 abutting against one of the straight positioning baffles 411, which is located on the inner wall of the lower side of the housing 41 in the figure. The other straight positioning baffle 411 abuts against the support portion 421 of the speaker bracket 42.

[0037] like Figure 5 As shown, the surface of the speaker bracket 42 is provided with an adhesive coating surface for adhesive sealing with the housing 41. The adhesive coating surface includes the bottom surface 424a of the support part 421 and the side surface 424b of the clearance part 423 near the sound outlet 413 and the side surface 424c near the straight positioning barrier wall 411.

[0038] The assembly process of the speaker module 43 with the speaker bracket 42 and the housing 41 in this application is as follows: First, the speaker module 43 is assembled according to... Figure 6 As shown, the speaker module 43 is installed on the speaker bracket 42, and the connection between the speaker module 43 and the speaker bracket 42 is sealed with adhesive. Then...
