[0034] Loudspeaker electronic components are essential in electronic devices, playing a crucial role in their communication and audio-visual playback functions. A loudspeaker is a transducer that converts electrical signals into sound signals. The performance of a loudspeaker significantly impacts sound quality; therefore, loudspeakers have specific installation requirements and necessitate a mounting structure for connection and assembly. In related technologies, the vibrations generated by loudspeakers can affect the resonance of surrounding components and the entire device, leading to sound quality loss, such as the generation of noise.

[0035] To address the aforementioned problems, this invention proposes a loudspeaker vibration damping structure, aiming to improve the sound quality of the loudspeaker. Figures 1 to 5 This is an embodiment of the loudspeaker vibration damping structure of this utility model.

[0036] Please refer to Figures 1 to 5 This utility model proposes a loudspeaker vibration damping structure 1000, including a housing 1, a loudspeaker 2, and a vibration damping member 3. The housing 1 has a receiving cavity 13 and a first sound outlet 14 communicating with the receiving cavity 13. The loudspeaker 2 is received in the receiving cavity 13. The vibration damping member 3 is sandwiched between the inner wall of the receiving cavity 13 and the loudspeaker 2.

[0037] In this invention, the speaker 2 vibrates when it emits sound, causing the housing 1 to vibrate and thus resonating. Consequently, the speaker 2 vibrates excessively at a specific frequency, resulting in audio distortion. By providing the damping element 3, the vibration generated by the speaker 2 can be absorbed, reducing the resonance between the speaker 2 and the housing 1 within the cavity 13 to a certain extent. This makes the output audio of the speaker 2 clearer, more accurate, and more balanced across frequency bands. Furthermore, reducing resonance can decrease the vibration and stress of the speaker 2, improving its durability and lifespan. The damping element 3 can be PSR damping foam or rubber; this invention does not limit this. By providing damping foam on opposite sides of the speaker 2's vibration direction, the vibration force of the speaker 2 can be effectively absorbed, thereby improving the sound quality of the speaker 2.

[0038] To further improve the sound quality of the speaker 2, please refer to [link / reference]. Figure 3 and Figure 5 In one embodiment of this utility model, the loudspeaker 2 includes a housing 21 and a loudspeaker body 22. The housing 21 has a cavity 23, and the loudspeaker body 22 is housed in the cavity 23. The housing 21 has a second sound outlet 24, which is connected to both the cavity 23 and the first sound outlet 14. The loudspeaker damping structure 1000 includes a sealing foam 4, which is arranged around the periphery of the second sound outlet 24 and located between the first sound outlet 14 and the second sound outlet 24 to isolate the cavity 13 and the second sound outlet 24. The sound emitted by the speaker body 22 is transmitted through the second sound outlet 24 to the first sound outlet 14, and then out of the housing 1. Since there is a gap between the housing 21 and the inner wall of the receiving cavity 13, after the sound is transmitted through the second sound outlet 24, the sound will enter the receiving cavity 13 through the gap. The sealing foam 4 can isolate the receiving cavity 13 from the second sound outlet 24, prevent the sound from entering the receiving cavity 13, and thus enhance the sound quality of the speaker damping structure 1000.

[0039] To prevent external dust from entering the housing 21, please refer to... Figure 3 and Figure 5 In one embodiment of this utility model, the loudspeaker vibration damping structure 1000 further includes a dustproof mesh 5. The dustproof mesh 5 is disposed on the inner wall of the receiving cavity 13 and located between the first sound outlet 14 and the sealing foam 4. The dustproof mesh 5 is provided to prevent external dust from entering the enclosure 21, thereby preventing dust from entering the loudspeaker body 22, which would cause poor sound output of the loudspeaker body 22 and even affect the normal operation of the loudspeaker 2. The dustproof mesh 5 can extend the service life of the loudspeaker 2.

[0040] To secure the housing 21 to the inner wall of the receiving cavity 13, please refer to [link / reference needed]. Figure 1 , Figure 3 and Figure 4In one embodiment of this utility model, the speaker vibration damping structure 1000 further includes at least one locking member 6. The inner wall of the receiving cavity 13 is provided with at least one connecting post 15, and the connecting post 15 has a mounting hole 151. The enclosure 21 has at least one mounting slot 211, the connecting post 15 passes through the mounting slot 211, and the locking member 6 passes through the mounting hole 151 to fix the enclosure 21 to the inner wall of the receiving cavity 13. The locking member 6 fixes the enclosure 21 to the inner wall of the receiving cavity 13, preventing the enclosure 21 from shaking within the receiving cavity 13, which would lead to a decrease in sound quality. Fixing the speaker 2 within the receiving cavity 13 ensures its stability during sound playback. The locking member 6 can be a pin or a screw; this utility model does not limit its application to either.

[0041] To avoid direct contact between the housing 21 and the inner wall of the receiving cavity 13, please refer to... Figure 1 , Figure 3 and Figure 4 In one embodiment of the present invention, the loudspeaker vibration damping structure 1000 further includes at least one vibration damping silicone 7, the vibration damping silicone 7 is fitted in the mounting through groove 211, the vibration damping silicone 7 has a through hole 71, and the vibration damping silicone 7 is sleeved on the connecting post 15 to isolate the inner wall of the mounting through groove 211 from the connecting post 15. The vibration-damping silicone 7 isolates the enclosure 21 from the inner wall of the receiving cavity 13, preventing hard contact between the enclosure 21 and the inner wall of the receiving cavity 13. Therefore, when the speaker body 22 vibrates during sound generation, the vibration-damping silicone 7 absorbs the vibration force, thereby enhancing the sound quality of the speaker 2. It also prevents wear caused by collisions between the enclosure 21 and the inner wall of the receiving cavity 13, thus improving the service life of the speaker vibration-damping structure 1000. The connecting post 15, the locking member 6, the mounting slot 211, and the vibration-damping silicone 7 can be provided in one or two ways; this utility model does not limit this. In this embodiment, three of each are provided. According to geometric principles, a plane can be uniquely determined by three non-collinear points. Providing three of these components increases the connection stability between the enclosure 21 and the inner wall of the receiving cavity 13.

[0042] Specifically, in one embodiment of this utility model, the locking member 6 is a bolt, the mounting hole 151 is a threaded hole, and the bolt is threadedly connected to the threaded hole to connect the housing 21 to the connecting post 15. The bolt is threaded to the threaded hole to enhance the connection stability between the housing 21 and the inner wall of the receiving cavity 13.

[0043] To enhance the connection stability between the vibration-damping silicone 7 and the housing 21, please refer to [link / reference needed]. Figure 1 , Figure 3 and Figure 4 In one embodiment of this utility model, the sidewall of the vibration-damping silicone 7 is provided with a relief groove 72 along its circumference, and the sidewall of the mounting through groove 211 is provided with a connecting protrusion 212. The connecting protrusion 212 is engaged with and abuts within the relief groove 72. The vibration-damping silicone 7 is engaged within the mounting through groove 211 through the opening of the mounting through groove 211, and the connecting protrusion 212 abuts within the relief groove 72. This increases the contact area between the enclosure 21 and the vibration-damping silicone 7, and effectively isolates the enclosure 21 from the inner wall of the receiving cavity 13. This strengthens the connection stability between the vibration-damping silicone 7 and the enclosure 21, and prevents the enclosure 21 from colliding with other parts during vibration. This achieves the connection between the enclosure 21 and the housing 1 while also improving the sound quality of the speaker 2.

[0044] For more details, please refer to Figure 1 , Figure 3 and Figure 4 In one embodiment of this utility model, the vibration-damping silicone 7 has a plurality of vibration-damping protrusions 73 on the side facing away from the connecting post 15, and the plurality of vibration-damping protrusions 73 are spaced apart circumferentially along the vibration-damping silicone 7. When the locking member 6 fixes the housing 21, the locking member 6 contacts the plurality of vibration-damping protrusions 73. Since the vibration-damping silicone 7 may wear during use, the plurality of vibration-damping protrusions 73 can reduce the contact area between the locking member 6 and the vibration-damping silicone 7, thereby reducing its wear and improving the service life of the vibration-damping silicone 7.

[0045] For ease of maintenance and inspection of the loudspeaker damping structure 1000, please refer to [link / reference needed]. Figure 3 In one embodiment of this utility model, the housing 1 includes a first housing 11 and a second housing 12 that are detachably connected, and the first housing 11 and the second housing 12 together form the receiving cavity 13. The detachable connection of the first housing 11 and the second housing 12 can be achieved by providing a first magnetic attraction part and a second magnetic attraction part that attract each other on opposite sides of the first housing 11 and the second housing 12, or by providing a snap-fit ​​buckle and a slot on opposite sides of the first housing 11 and the second housing 12. This utility model does not limit this approach. The detachable design of the housing 1 makes the maintenance, replacement of parts, cleaning, and customization of the speaker vibration damping structure 1000 more convenient and flexible, improving the maintainability of the speaker vibration damping structure 1000.

The specific structure of the speaker vibration damping structure 1000 is as described in the above embodiments. Since this electronic device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
