Abstract

The present disclosure provides a receiver module comprising a receiver, the receiver comprising a basin frame, a vibration system and a front cover, the receiver module further comprises: a fixing member disposed on the front cover, a noise canceling member fixed to a side of the fixing member adjacent to the front cover, and a microphone disposed on a side surface of the noise canceling member away from the vibration system; the fixing member comprises a body portion fixed on the front cover, an extending portion extending from the body portion in a direction away from the front cover, and a through hole penetrating through both the body portion and the extending portion; the noise canceling member is located outside the basin frame and fixed to the extending portion, and it comprises a main body portion and a sound absorption hole penetrating through the main body portion.

First claim

What is claimed is:

1. A receiver module comprising a receiver, wherein, the receiver comprises a basin frame, a vibration system fixed to the basin frame, and a front cover disposed on the basin frame by covering the basin frame, the front cover forms a front cavity with the vibration system, and the front cover comprises a body portion disposed on the basin frame by covering the basin frame, and a sound output hole penetrating through the body portion and in communication with the front cavity, wherein,
the receiver module further comprises: a fixing member disposed on the front cover by covering the front cover, a noise canceling member fixed to a side of the fixing member adjacent to the front cover, and a microphone disposed on a side surface of the noise canceling member away from the vibration system;
the fixing member comprises a body portion fixed on the front cover by covering the front cover, an extending portion extending from the body portion in a direction away from the front cover, and a through hole penetrating through both the body portion and the extending portion;
the noise canceling member is located outside the basin frame and fixed to the extending portion, and the noise canceling member comprises a main body portion and a sound absorption hole penetrating through the main body portion;
the main body portion is recessed with several embedded grooves spaced apart, and the extending portion is extended with several clasping pieces spaced apart in a direction approaching the front cover, the clasping pieces are clasped and fixed within the embedded grooves; the front cavity, the through hole, the sound absorption hole and a sound input hole of the microphone are sequentially in communication; and a sound wave of the front cavity is directed out of the noise canceling member through the through hole and the sound absorption hole and the noise is absorbed and canceled by the microphone.

2. The receiver module according to claim 1 , wherein, the sound absorption hole extends in a vibration direction of the vibration system from a side of the noise canceling member adjacent to the fixing member, and the microphone is disposed at a side of the noise canceling member away from the fixing member.

3. The receiver module according to claim 2 , wherein, the cross-sectional area of an end of the sound absorption hole adjacent to the fixing member is larger than that of an end of the sound absorption hole away from the fixing member.

4. The receiver module according to claim 2 , wherein, the sound absorption hole is an via circular.

5. The receiver module according to claim 1 , wherein, the receiver module further comprises a permeable spacer fixed to the fixing member, the permeable spacer completely covers the sound output hole and the through hole, and makes the sound output hole and the through hole in communication with outside, respectively.

6. The receiver module according to claim 5 , wherein, the permeable spacer comprises an annular frame fixed to the front cover and a permeable membrane adhered to the frame, and the permeable membrane completely covers the sound hole and the through hole.
