Description

Technical Field

[0001] The utility model belongs to the technical field of hearing aids, and particularly relates to a RIC type hearing aid. Background Technique

[0002] For the behind-the-ear RIC type hearing aid, the receiver inside the hearing aid is separated and directly placed into the ear canal, and is connected in the middle through an external sound guide tube. The farther the distance between the microphone and the receiver, the lower the probability of howling. Due to the lengthening of the distance between the receiver and the microphone, the probability of howling generated after wearing the RIC machine will be greatly reduced. The external auditory canal resonance effect of the RIC type hearing aid is smaller, the middle frequency has a smoother response, and the gain and output of the high frequency can be larger. It can have both the concealment of the sound guide tube and better sound quality. This type of hearing aid is also very concealed when worn. From the front and side, often only a thin line can be seen, and it is easy to be ignored if not noticed carefully. From the back, the small body of the hearing aid can be seen, and it is very beautiful to use.

[0003] The existing hearing aids are mainly charged through an externally connected USB charging cable. This charging method is not only cumbersome, but also the frequent plugging and unplugging of the charging interface will cause poor contact. In addition, during the busy work process, this plug-in charging method cannot charge the hearing aid at any time, which brings inconvenience to users. Content of the Utility Model
