Abstract

The invention relates to a bone conduction hearing aid device, comprising an in-vitro voice processor which comprises a shell, a metal disk, an electromagnetic vibrator placed in the shell, a microphone and a circuit board, wherein a digital signal processor DSP is integrated and mounted on the circuit board. A vibrator packaging and separating cabin is arranged in the shell. A port is arranged on the right side wall of the shell. The port is communicated with the vibrator packaging and separating cabin. An output end part of the electromagnetic vibrator stretches out of the port and is connected with the metal disk. At least one microphone is arranged on the wall of the shell. The electromagnetic vibrator is arranged in the vibrator packaging and separating cabin. The port is communicated with the vibrator packaging and separating cabin. The output end part of the electromagnetic vibrator stretches out of the port and is connected with the center of the metal disk. According to the device, the electromagnetic vibrator is placed in the vibrator packaging and separating cabin. The sound propagated from the electromagnetic vibrator to the microphone is reduced and attenuated, so the sound propagated form the electromagnetic vibrator to the microphone is reduced or attenuated, and the howling of the bone conduction hearing aid device is greatly weakened.

Description

technical field [0001] The invention relates to a hearing aid, in particular to a bone conduction hearing aid. Background technique [0002] A bone anchor hearing aid is a hearing aid based on the theory of bone conduction. It is divided into an external speech processor part and an implant part implanted in the patient's head. The bone anchor hearing aid uses the human skull as a channel for sound transmission into the inner ear. For conduction For patients with permanent deafness, the bone-anchor hearing aid bypasses the patient's outer ear and middle ear, and transmits the sound directly to the patient's normal cochlea through a metal implant; One layer goes to the normal side. Most bone-anchored hearing aids require a titanium rod or plate to be surgically implanted into the skull with a small joint that exposes the patient's skin; the voice processor of the bone-anchored hearing aid is mounted on this joint , and transmit the sound vibration to the implant through the ...
