Description

Technical Field

[0001] This utility model relates to the field of side-entry silicon microphone technology, and in particular to the dustproof and airflow guiding cavity structure of side-entry silicon microphone. Background Technology

[0002] Side-entry silicon microphones are a type of microphone based on MEMS (Micro-Electro-Mechanical Systems) technology. Their core feature is that sound enters the microphone's pickup area from the side. They are widely used in consumer electronics, smart homes, and other fields. In the composition of a side-entry silicon microphone, the dustproof and airflow-guiding cavity structure is one of the main dustproof components.

[0003] The existing side-entry silicon microphones need further improvement in terms of dust protection and sound pickup. Utility Model Content

[0004] The purpose of this invention is to provide a side-entry silicon microphone dustproof and airflow guiding cavity structure that can further improve the dustproof effect, while also improving the clarity and effect of sound reception, making it highly practical.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The side-entry silicon microphone dustproof and airflow guiding cavity structure includes a circuit board. A dustproof cover is adhered to one outer surface of the circuit board. A sound receiving hole is provided on one outer surface of the dustproof cover. A mounting base is installed inside the sound receiving hole. A support base is inserted and snapped into one end of the mounting base. A second diaphragm is adhered to the end face of the support base by adhesive.

[0007] By adopting the above technical solution, dustproof operation can be performed while also performing a single resonance operation, which improves the sound propagation and enhances the sound clarity and effect of the side-entry silicon microphone.

[0008] Furthermore, a micro-motor system and an ASIC chip are disposed on the outer surface of the circuit board, and the micro-motor system and the ASIC chip are electrically connected by multiple gold wires.

[0009] By adopting the above technical solution, the side-entry silicon microphone can operate normally.

[0010] Furthermore, each of the symmetrical side surfaces of the mounting base is provided with a mounting hole, and a first vibrating diaphragm is adhered to the port of each mounting hole.

[0011] By adopting the above technical solution, single-resonance operation can be achieved.

[0012] Furthermore, a dust cover is fixedly connected to the end face of the mounting base, and the outer surface of the dust cover is provided with multiple through holes, and the dust cover is arc-shaped.

[0013] By adopting the above technical solutions, effective dust prevention operations can be carried out.

[0014] Furthermore, a rubber gasket is fitted onto the outside of the mounting base, and an adhesive layer is provided on both symmetrical sides of the rubber gasket.

[0015] By adopting the above technical solution, it is easy to install and fix the mounting base.

[0016] Furthermore, one end of the support base is provided with a locking position, and notches are provided on both symmetrical sides of the support base.

[0017] By adopting the above technical solution, sound propagation is facilitated.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] 1. This utility model provides a sound-receiving hole on the side surface of the dust cover. During normal use, the sound can be received through the sound-receiving hole on the side. In this process, the sound-receiving hole on the side can reduce the chance of dust entering the dust cover, thereby improving the dustproof effect of the entire side-entry silicon microphone.

[0020] 2. This utility model involves installing a mounting base inside the microphone hole, installing a support base at the port of the mounting base, attaching a second diaphragm to the end face of the support base, and attaching a first diaphragm to each of the symmetrical side surfaces of the mounting base. A dust cover is fixedly installed at the port of the mounting base. The dust cover can be used for dust prevention. At the same time, when sound is transmitted into the interior of the dust cover, it can effectively cause the first and second diaphragms to resonate. This can effectively improve the sound transmission efficiency and the sound reception effect of the side-entry silicon microphone, thus significantly improving its practicality.

[0024] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Reference Figure 1 , Figure 2The side-entry silicon microphone dustproof and airflow guiding cavity structure includes a circuit board 1. A dust cover 4 is attached to one outer surface of the circuit board 1. A sound receiving hole 5 is provided on one outer surface of the dust cover 4. A micro-motor system 2 and an ASIC chip 3 are provided on the outer surface of the circuit board 1. The micro-motor system 2 and the ASIC chip 3 are electrically connected by multiple gold wires. By providing a sound receiving hole 5 on the side surface of the dust cover 4, sound can be received through the side sound receiving hole 5 during normal use. In this process, the side sound receiving hole 5 can reduce the probability of dust entering the interior of the dust cover 4, thereby improving the dustproof effect of the entire side-entry silicon microphone.

[0026] Reference Figure 1 The receiver hole 5 has a mounting base 6 installed inside. A support base 10 is inserted and clipped into one end of the mounting base 6. A second diaphragm 11 is glued to the end face of the support base 10. Each of the symmetrical side surfaces of the mounting base 6 has a mounting hole, and a first diaphragm 9 is glued to the port of each mounting hole. A dust cover 8 is fixedly connected to the end face of the mounting base 6. The outer surface of the dust cover 8 has multiple through holes and is arc-shaped. A rubber gasket 7 is fitted onto the outside of the mounting base 6. Adhesive layers are applied to both symmetrical side surfaces of the rubber gasket 7. One end of the support base 10 has a locking position. The symmetrical side surfaces of the support base 10... All are provided with notches and slots. A mounting base 6 is installed inside the sound-receiving hole 5, a support base 10 is installed at the port of the mounting base 6, a second diaphragm 11 is attached to the end face of the support base 10, and a first diaphragm 9 is attached to the symmetrical side surface of the mounting base 6. A dust cover 8 is fixedly installed at the port of the mounting base 6. At this time, the dust cover 8 can be used for dust prevention. At the same time, when the sound is transmitted into the interior of the dust cover 4, it can effectively cause the first diaphragm 9 and the second diaphragm 11 to resonate. This can effectively improve the sound transmission efficiency, improve the sound reception effect of the side-entry silicon microphone, and effectively improve its practicality.

[0027] Working principle: In use, first assemble the various structures, and then install the assembled side-entry silicon microphone in the designated position. Normal use is then possible. During this process, the side sound-receiving hole 5 reduces the chance of dust entering the dust cover 4, thus improving the overall dustproof effect of the side-entry silicon microphone. Simultaneously, by installing a mounting base 6 inside the sound-receiving hole 5, and a support base 10 at the port of the mounting base 6, a second diaphragm 11 is attached to the end face of the support base 10. A first diaphragm 9 is attached to the symmetrical side surface of the mounting base 6. A dust cover 8 is fixedly installed at the port of the mounting base 6. Dust protection is achieved using the dust cover 8. Simultaneously, when sound is transmitted into the dust cover 4, it effectively induces resonance between the first diaphragm 9 and the second diaphragm 11. This effectively improves sound transmission efficiency and the sound reception effect of the side-entry silicon microphone, significantly enhancing its practicality.
