[0002] In loudspeaker manufacturing, the core function of the rubber sleeve is to fix the diaphragm, seal the magnetic circuit, buffer vibration, and transmit sound waves. However, existing loudspeaker rubber sleeves are mostly made of rubber or silicone, which have problems such as poor wear resistance, fast aging, and low environmental friendliness. Rubber sleeves are prone to cracking under long-term vibration, resulting in diaphragm displacement deviation. Although silicone is flexible, it is expensive and has a fixed hardness, making it difficult to balance low-frequency and high-frequency performance. To address this problem, the inventor designed a rubber sleeve for loudspeakers. Utility Model Content

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this utility model, "multiple" means two or more, unless otherwise explicitly specified.
[0022] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0023] Please see Figures 1 to 4 The present invention provides an embodiment of a speaker sleeve, which includes a first mounting strip 1, a second mounting strip 2, a third mounting strip 3, and an anti-overflow component 4; the first mounting strip 1, the second mounting strip 2, and the third mounting strip 3 are distributed from the outside to the inside, and the first mounting strip 1, the second mounting strip 2, and the third mounting strip 3 are designed as a single piece, and the anti-overflow component 4 is disposed at the bottom of the third mounting strip 3;
[0024] The first mounting strip 1, the second mounting strip 2, and the third mounting strip 3 are made of TPU;
[0025] The high elasticity and abrasion resistance of TPU enable the rubber sleeve to maintain a stable seal during long-term vibration;
[0026] The height of the first mounting strip 1 and the third mounting strip 3 is the same, and the height of the second mounting strip 2 is higher than the height of the first mounting strip 1 and the third mounting strip 3;
[0027] The first mounting strip 1 forms an outer sealing layer to prevent dust and moisture from entering. The second mounting strip 2 serves as a core support layer to balance the pressure between the inner and outer layers and ensure a stable connection between the rubber sleeve and the speaker components. The third mounting strip 3 directly contacts the precision components inside the speaker.
[0028] The anti-overflow component 4 includes a connecting ring 41 and a protective ring 42; the connecting ring 41 is glued and fixed to the surface of the protective ring 42, and the surface of the protective ring 42 is fixed to the surfaces of the second mounting strip 2 and the third mounting strip 3;
[0029] The connecting ring 41 is a quick-positioning rubber sleeve to prevent misalignment during installation and physically prevents glue from overflowing from the edge of the third mounting strip 3. The protective ring 42 enhances the connection stability with the mounting platform.
[0030] The height of the connecting ring 41 is higher than the height of the protective ring 42, and the connecting ring 41 is located at the bottom of the third mounting strip 3, while the protective ring 42 is located at the bottom of the second mounting strip 2.
[0031] The protective ring 42 has a conical groove 43 inside. The conical groove 43 is narrow at the top and wide at the bottom. The conical groove 43 is distributed in a circular array inside the protective ring 42 with the center of the protective ring 42.
[0032] The tapered groove 43, narrower at the top and wider at the bottom, restricts the lateral flow of the adhesive, forcing it to penetrate vertically and increasing the contact depth. This allows the adhesive to be guided deep into the groove, forming anchor points after curing and enhancing the adhesion between the protective ring 42 and the mounting platform. Furthermore, the circumferential array design of the tapered groove 43 ensures that the protective ring 42 is evenly stressed, preventing localized pull-out that could lead to detachment.
[0033] The inner side of the third mounting strip 3 is provided with an inclined groove 5, and the inner surface of the third mounting strip 3 is inclined at 45 degrees.
[0034] The stepped height design of the inclined groove 5 ensures the sealing of each part and avoids sound leakage or resonance.
[0035] Working principle: When the adhesive strip needs to be installed in the required position, the adhesive is first applied to the required position. Then, with the design of the connecting ring 41, the adhesive sleeve is quickly and accurately placed in the required position. With the design of the conical groove 43, the protective ring 42 is more stably connected to the installation platform. The connecting ring 41 is located at the bottom of the second installation strip 2, thereby preventing the adhesive from overflowing from the edge of the first installation strip 1.
[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
