Abstract

A microphone includes: a housing; a microphone unit that outputs a sound signal disposed in the housing; an elastic member mounted to the microphone unit; and a weight member mounted to the elastic member.

Claims

1. A microphone comprising:

a housing;

a microphone unit that outputs a sound signal disposed in the housing;

an elastic member mounted to the microphone unit; and

a weight member mounted to the elastic member.

2. The microphone according to claim 1, further comprising an insulator supporting the microphone unit with respect to the housing and in contact with the housing at a predetermined position in a vertical direction,

wherein a weight of the weight member is determined to allow a center of gravity of a system constituted by the microphone unit, the elastic member, and the weight member to be located at the predetermined position.

3. The microphone according to claim 1, further comprising an adjusting member configured to adjust elasticity of the elastic member.

4. The microphone according to claim 1, further comprising a plurality of pairs of ones of the elastic member and a plurality of ones of the weight member.

5. The microphone according to claim 1, wherein the elastic member:

has a disc shape,

is mounted to the microphone unit at a portion of the elastic member located in a vicinity of a center of the disc shape of the elastic member, and

holds the weight member at a distance from the portion of the elastic member located in the vicinity of the center.

6. The microphone according to claim 5, further comprising:

an extending member extending from a bottom surface of the microphone unit,

wherein the portion of the elastic member located in the vicinity of the center is secured to the extending member to mount the elastic member to the microphone unit.

7. The microphone according to claim 6, wherein the portion of the elastic member located in the vicinity of the center includes a hole through which the extending member extends.

8. The microphone according to claim 7, wherein:

the extending member is a screw, and

the portion of the elastic member located in the vicinity of the center is held between a pair of nuts secured to the screw and between a pair of washers inserted in the screw, with the screw inserted in the hole, to mount the elastic member to the microphone unit.

9. The microphone according to claim 5, wherein the weight member has a ring shape disposed at a distance from the portion of the elastic member located in the vicinity of the center.

10. The microphone according to claim 5, wherein:

the weight member has a ring shape, and

the elastic member includes;

a weight-member holder having a ring shape configured to hold the weight member; and

a coupling member having a cross shape and provided on an inner circumferential side of the weight-member holder.

11. The microphone according to claim 10, further comprising:

an extending member extending from a bottom surface of the microphone unit,

wherein the coupling member at a center thereof includes a hole through which the extending member is inserted.

12. The microphone according to claim 11, wherein:

the extending member is a screw, and

a portion of the coupling member of the elastic member located in the vicinity of the center is held between a pair of nuts secured to the screw and between a pair of washers inserted in the screw, with the screw inserted in the hole, to mount the elastic member to the microphone unit.

13. The microphone according to claim 1, wherein one of the elastic member or the weight member is in contact with an inner wall of the housing.

14. The microphone according to claim 1, wherein:

the elastic member has a disc shape, and

a first surface of the elastic member is mounted on a bottom surface of the microphone unit, and the weight member is mounted on a second surface of the elastic member.

15. The microphone according to claim 1, wherein:

the elastic member is a coil spring, and

a first end of the coil spring is attached to a bottom surface of the microphone unit, and a second end of the coil spring is attached to the weight member.
