[0002] Currently, in the consumer electronics field, especially in devices such as smartphones, tablets, and smart speakers, the acoustic performance and mounting reliability of miniature speakers are of paramount importance. Their main function is to convert electrical signals into sound through the speaker, reproducing the effect of the scene as closely as possible. They are widely used in home theater systems, background music systems, multimedia audio systems, public address systems, and other fields. In existing technologies, speakers are fixed to the device housing by their own mounting brackets and by screws or direct clips to achieve the assembly and positioning of the speaker on the housing.

[0003] However, whether it is screw fastening or clip fixing, there may be slight gaps in the fit during the assembly process, or loosening may occur after long-term use of the product. These gaps or loosening can cause undesirable mechanical resonance between the speaker and the housing, resulting in abnormal noise, sound quality distortion (such as crackling), and other problems, which in turn affect the user experience and limit the scope of application.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a resonant speaker structure. It utilizes a positioning plate to contact and position the speaker unit, and a connecting plate to connect and fix it to the housing. This reduces the transmission of structural vibrations generated by the speaker unit during operation to the housing, thereby avoiding abnormal noises and sound quality degradation caused by resonance, ensuring a good user experience, excellent usability, and wide applicability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A resonance-resistant speaker structure includes a housing, a speaker unit, and a vibration-damping cover; wherein:

[0008] The housing has an internal acoustic cavity and an upwardly extending mounting platform. The mounting platform has an installation port communicating with the acoustic cavity. The speaker unit extends into the acoustic cavity through the installation port and is mounted on the mounting platform. The sound output end of the speaker unit faces upward.

[0009] The vibration damping cover is mounted on the mounting platform. The vibration damping cover includes an integrally connected positioning plate, a side plate, and a connecting plate. The positioning plate extends circumferentially along the edge of the speaker unit. The side plate extends downward from the outer end of the positioning plate. The connecting plate extends horizontally outward from the lower end of the side plate. The lower end of the positioning plate contacts and positions the edge of the speaker unit. The lower end of the connecting plate is fixed to the housing.

[0010] As a preferred embodiment, the upper end of the mounting platform has a support protrusion extending toward the vibration damping cover, the support protrusion being located beside the mounting opening, and the upper end of the support protrusion being connected to the lower end of the positioning plate.

[0011] As a preferred embodiment, the support protrusion extends circumferentially along the periphery of the mounting opening.

[0012] As a preferred embodiment, the housing is provided with a first mounting groove, which extends circumferentially along the lower edge of the mounting platform, and the lower end of the connecting plate is disposed on the inner end face of the first mounting groove.

[0013] As a preferred embodiment, the upper end of the mounting platform is provided with a second mounting groove, the mounting opening is formed at the center of the second mounting groove, and the speaker unit has a bracket, which is disposed on the second mounting groove.

[0014] As a preferred embodiment, a buffer pad is provided between the bracket and the second mounting slot.

[0015] As a preferred embodiment, the edge of the buffer pad is provided with an upwardly extending edge, the inner wall of which is connected to the outer wall of the support.

[0016] As a preferred embodiment, the upper end of the vibration damping cover is provided with a number of raised lines arranged sequentially from the inside out.

[0017] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly uses the design of the anti-vibration cover to position the speaker unit in contact with the positioning plate and connect and fix it to the housing with the connecting plate, so as to reduce the structural vibration generated by the speaker unit during operation and transmit it to the housing, thereby avoiding abnormal noise and sound quality degradation caused by resonance, and ensuring the user experience. At the same time, the setting of the connecting plate is conducive to the connection operation of the anti-vibration cover on the housing, with good usability and wide applicability.

[0018] Secondly, the support protrusions serve as a support connection between the positioning plate and the mounting platform, improving the stability of the vibration damping cover and enhancing its practicality. Meanwhile, the first mounting groove is designed to match and position the connecting plate and the housing, facilitating subsequent bonding and fixing operations. Additionally, the second mounting groove is designed to position and connect the speaker unit on the mounting platform, which is beneficial for assembling and fixing the speaker unit on the mounting platform, resulting in excellent usability.

[0019] Furthermore, the inclusion of a buffer pad allows vibrations generated by the speaker unit during operation to be absorbed and cushioned, further reducing resonance between the speaker unit and the housing, thus improving the product's stability and practicality. Additionally, the textured design enhances the structural strength of the vibration-damping cover, preventing noise from vibrations and resisting the impact of external collisions on the speaker unit, thereby protecting it.
