Description

Technical Field

[0001] The utility model relates to the technical field of hearing aid earphones, in particular to a hearing aid earphone based on a silicon microphone waterproof net. Background Art

[0002] A silicon microphone is a miniature microphone made of silicon semiconductor material, also known as a silicon microphone or a silicon microphone head. Silicon microphones can be divided into digital silicon microphones and analog silicon microphones, and are widely used in consumer electronics fields such as mobile communications, personal computers, and digital products. The working principle of a silicon microphone is based on capacitive microelectromechanical technology, and through the integration of an analog amplification circuit and an ADC circuit, the conversion and processing of sound signals are realized. Silicon microphones have the characteristics of small size, light weight, and resistance to falling and impact, and can directly output digital signals, becoming digital microphones.

[0003] The silicon microphone in a hearing aid earphone is very easy to get into sweat and water droplets. Sweat or water droplets may cause a change in the resistance on the surface of the silicon microphone, thereby affecting the conduction and processing of sound, resulting in distorted or unclear sound quality. And existing earphones are usually buckled together by two groups of cover plates, and there will be gaps at the connection positions of the cover plates. Dust and moisture are easy to enter the earphone through the gaps. The entry of dust and moisture into the earphone interior may cause a short circuit, especially to the circuit board and connection points inside the earphone, which may cause the device to suddenly fail. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a hearing aid earphone based on a silicon microphone waterproof net, which has the characteristics of preventing moisture intrusion, preventing dust and impurities from intrusion, improving durability, and extending the product life.

[0005] To achieve this purpose, the utility model adopts the following technical solutions:

A circuit board is fixedly installed inside the lower cover body, and a noise reduction processing module is fixedly connected to the upper surface of the circuit board. Both the first silicon microphone head and the second silicon microphone head are connected to the noise reduction processing module.

[0008] Further, a function switching key, a volume key, and a power key are provided on the right side of the isolation board and below the first sound receiving hole. The volume key includes a volume increase key and a volume decrease key, and the volume increase key and the volume decrease key are combined. The ends of the function switching key, the volume key, and the power key are all electrically connected to the circuit board through microswitches.

[0013] The technical solution provided by the present utility model may include the following beneficial effects:

[0014] 1. By covering the first silicon microphone and the second silicon microphone with a silicon microphone waterproof net, the present utility model can block impurities such as dust and sand grains from entering the inside of the silicon microphone, thereby preventing the influence of dust accumulation on the performance of the microphone, effectively preventing moisture from entering the inside of the silicon microphone, reducing corrosion or short circuit caused by moisture, and thus extending the service life of the silicon microphone.

[0015] 2.
