Abstract

A microphone assembly includes a base and a microphone cover. The base defines a receiving groove for receiving a microphone and a first recess communicating with the receiving groove. The microphone cover defines a second recess covering the base. The first recess and the second recess of the microphone cover together define a sound channel communicating with the receiving groove therebetween, and running through an end of the base.

Claims

1. A microphone assembly, comprising:

a base including a microphone at a first surface, a first recess at a second surface, and a receiving groove communicating with the microphone and the first recess; and

a microphone cover defining a second recess;

wherein the microphone cover covers on the base;

the first recess and the second recess together define a sound channel, one end of the sound channel communicating with the microphone by the receiving groove therebetween, another end of the sound channel runs through an end of an external of the base.

2. The microphone assembly as claimed in claim 1, wherein an adhesive layer is located between the base and the microphone cover.

3. The microphone assembly as claimed in claim 1, wherein the base defines a through hole;

the microphone cover comprises a post, the post passes through the through hole and is melted to fix the microphone cover on the base.

4. The microphone assembly as claimed in claim 3, wherein an adhesive layer defining an opening is located between the base and the microphone cover, and the post pass through the opening.

5. An electronic device, comprising:

a housing;

a microphone; and

a microphone cover covering on the housing, the housing defining a receiving groove for receiving a microphone and a first recess communicating with the receiving groove;

wherein the first recess and the microphone cover together define a sound channel communicating with the receiving groove therebetween, the sound channel runs through an end of the housing.

6. The electronic device as claimed in claim 5, wherein an adhesive layer is located between the housing and the microphone cover.

7. The electronic device as claimed in claim 5, wherein the housing defines a through hole;

the microphone cover comprises a post, the post passes through the through hole and is melted to fix the microphone cover on the housing.

8. The electronic device as claimed in claim 7, wherein an adhesive layer defining an opening is located between the base and the microphone cover, and the post pass through the opening.

9. The electronic device as claimed in claim 5, wherein the microphone cover defines a second recess, the first recess and the second recess together define the sound channel therebetween.
