Abstract
Description
Technical Field
[0001] This utility model relates to a microphone sealing structure and belongs to the field of electronic component technology. Background Technology
[0002] In the sealing technology of acoustic components, especially microphones, such as Figure 7 As shown, traditional sealing methods primarily rely on the sealing ring B integrated into microphone A, which, along with microphone A, is mounted in the microphone mounting slot D on the electronic device housing C. While this sealing method can meet basic sealing requirements to a certain extent, its sealing effect tends to deteriorate over prolonged use or in extreme environments, leading to compromised sound quality. Furthermore, traditional sealing methods are prone to displacement or damage during assembly, increasing production costs and maintenance complexity. Clearly, a seal can be achieved by installing silicone gaskets around the microphone. The advantages are lower cost and easier installation; the disadvantages are unstable sealing performance, susceptibility to environmental temperature and humidity, and aging after prolonged use. Therefore, developing a microphone sealing structure has become a pressing issue for those skilled in the art. Utility Model Content
[0003] The present invention addresses the aforementioned shortcomings by providing a microphone sealing structure.
[0004] The above-mentioned objective of this utility model is achieved through the following technical solution: a microphone sealing structure, comprising an electronic device housing, an elastic rubber component, and a microphone, wherein the electronic device housing is provided with a microphone hole, the elastic rubber component is provided with an integrally formed microphone mounting cylinder and a silicone key cap, the microphone mounting cylinder is inserted into the microphone hole, the microphone is inserted into the microphone mounting cylinder, and the outer wall of the microphone mounting cylinder containing the microphone is constrained and squeezed by the inner wall of the microphone hole to achieve a stable seal.
[0005] Furthermore, the microphone mounting tube and the microphone adopt an interference fit structure.
[0006] Furthermore, the inner cavity of the microphone mounting tube is provided with a microphone embedding slot, forming a raised step on the rear side of the microphone, which can stably hold the microphone.
[0007] Furthermore, the elastic component is made of elastic materials such as silicone or rubber. The silicone is high-performance silicone, which has good elasticity and weather resistance, and can effectively prevent sound leakage.
[0008] Furthermore, the electronic device housing is made of plastic.
[0009] The advantages of this invention compared to existing technologies are: This invention eliminates the need for a pre-installed silicone sealant on the microphone head, improves the stability and reliability of the sealing effect through a new sealing method, reduces displacement and damage during assembly, and extends the service life of the sealing material. Specifically:
[0010] 1) The sealing effect is more stable and reliable, and it can maintain good sealing performance under different environmental conditions.
[0011] 2) It reduces displacement and damage during the assembly process, thereby lowering production costs and maintenance difficulty.
[0012] 3) It extends the service life of the sealing material and improves the overall durability and reliability. Attached Figure Description
