Waterproof microphone, implementation method thereof, and electronic product

Abstract

The invention discloses a waterproof microphone, an implementation method thereof, and an electronic product. The waterproof microphone comprises a shell, wherein a sound access hole is formed in the shell; a waterproof membrane component is adhered to the inner side of the shell at the sound access hole part; a limited slot is also arranged in the inner side of the shell; a rubber mat reserving with a sound hole is adhered with a microphone component to form a combination body; the combination body is loaded in the limited slot in the inner side of the shell under the state of being extruded toward the shell side, so that the rubber mat and the waterproof membrane component contact in a sealing way, and are fixed in the limited slot through adhesive dispensing under an extrusion state. According to the waterproof microphone provided by the invention, the rubber mat reserving with the sound hole and the microphone component are fixed through adhesive dispensing under a pressure maintaining state, and an elastic pressing plate in the prior art is replaced, so that the product cost can be remarkably reduced, and compared with the application of the elastic pressing plate, the sealing stability of the fixed manner through adhesive dispensing under the pressure maintaining state is higher, the dimensional requirement on parts is reduced, the design precision can be reduced, and the processing difficulty and the cost are reduced.

Description

technical field [0001] The invention relates to the technical field of microphones, in particular to a waterproof microphone, its realization method and an electronic product. Background technique [0002] The consumer electronics market is developing rapidly, and various new products are constantly emerging. At the same time, with the improvement of consumer demand and the expansion of application fields, the functions of consumer electronic products are becoming more and more perfect. As a basic requirement, waterproofing is a function that most existing products have. [0003] Waterproof is divided into 8 grades of IPX1-IPX8 according to the standard. When the product is a single whole and there is no need for interaction with the outside world or Unicom, the waterproof function is easier to achieve. However, when structures such as microphones appear in products, waterproofing above level 7 is still a difficult point in the industry. In existing electronic products, t...

AI Technical Summary

Problems solved by technology

In order to ensure the acoustic performance of the product, the sound transmission path between the air-permeable membrane and the sound hole of the microphone must be sealed well, and an elastic body must be assembled between the air-permeable membrane and the microphone to form a closed sound cavity required for the microphone to work, such as figure 1 As shown, the existing products mostly use the waterproof membrane assembly 1 plus the microphone silicone sleeve 2 and the elastic pressing sheet 4 to realize the waterproofing of the microphone assembly 3, and the cost is relatively high. It will cause displacement and deformation, etc., resulting in unstable sealing performance, and most of the microphones of existing products use the top sounding method, which is directly wrapped in the silicone sleeve to realize the sealing of the microphone, and the sealing performance is not stable enough
