Abstract

A supporter for use in an electroacoustic transducer device including a housing and an electroacoustic transducer mounted to the housing using the supporter, the supporter including: a truncated conical shaped body including: a first portion configured to be held in contact with the electroacoustic transducer at a first position; and a second portion configured to be held in contact with the housing at a second position, wherein the second position is disposed spaced from the first position along an axial direction of an axis of the truncated conical shaped body.

First claim

What is claimed is:

1. A supporter for use in an electroacoustic transducer device including a housing and an electroacoustic transducer included in a microphone and configured to pickup sound and output a sound signal, mounted to the housing using the supporter, the supporter comprising:
a truncated conical shaped body including:
a first portion configured to be held in contact with the electroacoustic transducer at a first position; and
a second portion configured to be held in contact with the housing at a second position,
wherein the second position is disposed spaced from the first position along an axial direction of an axis of the truncated conical shaped body.

2. The supporter according to claim 1 , wherein the first portion is located at a height level lower than that of the second portion, in a state where the axis is extending vertically.

3. The supporter according to claim 1 , wherein the truncated conical shaped body further includes at least one slot disposed between the first portion and the second portion.

4. The supporter according to claim 3 , wherein:
the truncated conical shaped body includes a circumferential wall connecting the first portion and the second portion, and
the at least one slot extends along a circumferential direction of the circumferential wall.

5. The supporter according to claim 4 , wherein the circumferential wall includes a plurality of slots, including the at least one slot, that are symmetrically arranged around the axis.

6. The supporter according to claim 4 , wherein:
the first portion is a first end face configured to be held in contact with the electroacoustic transducer at an inner circumferential portion of the first end face, and
the second portion is a second end face configured to be held in contact with the housing at an outer circumferential portion of the second end face.

7. The supporter according to claim 6 , wherein the at least one slot is disposed so that a line extending along a shortest path from the first end face to the second end face intersects the at least one slot.

8. The supporter according to claim 3 , wherein:
the truncated conical shaped body includes a circumferential wall connecting the first portion and the second portion,
the circumferential wall includes a plurality of slots, including the at least one slot, disposed spaced apart from each other in the circumferential direction of the circumferential wall, and
the plurality of slots each include:
a first slot portion disposed at a first-diameter region of the circumferential wall along a first diameter that is larger than an inside diameter of the first end face and smaller than an outside diameter of the second end face; and
a second slot portion disposed at a second-diameter region of the circumferential wall along a second diameter that is larger than the first diameter and smaller than the outside diameter of the second end face.

9. The supporter according to claim 8 , wherein the first slot portion and the second slot portion of each of the plurality of slots are shifted relative to each other along the axial direction.

10. The supporter according to claim 8 , wherein each of the plurality of slots include a connecting portion connecting the first slot portion and the second slot portion.

11. The supporter according to claim 8 , wherein the plurality of slots are arranged so that the first slot portion of one slot, among the plurality of slots, and the second slot portion of a neighboring slot, among the plurality of slots, that neighbors the one slot, partly overlap in the circumferential direction.

12. The supporter according to claim 1 , wherein the truncated conical shaped body is made of an elastic material.

13. An electroacoustic transducer device comprising:
a housing;
an electroacoustic transducer included in a microphone and configured to pickup sound and output a sound signal; and
a supporter mounting the electroacoustic transducer to the housing, the supporter comprising a truncated conical shaped body including:
a first portion held in contact with the electroacoustic transducer at a first position; and
a second portion held in contact with the housing at a second position,
wherein the second position is disposed spaced from the first position along an axial direction of an axis of the truncated conical shaped body.

14. The electroacoustic transducer device according to claim 13 , further comprising a plurality of supporters each corresponding to the supporter.

15. The electroacoustic transducer device according to claim 13 , wherein the truncated conical shaped body further includes at least one slot disposed between the first portion and the second portion.

16. The electroacoustic transducer device according to claim 15 , wherein:
the truncated conical shaped body includes a circumferential wall connecting the first portion and the second portion, and
the at least one slot extends along a circumferential direction of the circumferential wall.

17. The electroacoustic transducer device according to claim 16 , wherein:
the first portion is a first end face held in contact with the electroacoustic transducer at an inner circumferential portion of the first end face,
the second portion is a second end face held in contact with the housing at an outer circumferential portion of the second end face, and
the at least one slot is disposed so that a line drawn along a shortest path from the first end face to the second end face intersects the at least one slot.

18. The electroacoustic transducer device according to claim 15 , wherein:
the truncated conical shaped body includes a circumferential wall connecting the first portion and the second portion,
the circumferential wall includes a plurality of slots, including the at least one slot, disposed spaced apart from each other in the circumferential direction of the circumferential wall, and
the plurality of slots each include:
a first slot portion disposed at a first-diameter region of the circumferential wall along a first diameter that is larger than an inside diameter of the first end face and smaller than an outside diameter of the second end face; and
a second slot portion disposed at a second-diameter region of the circumferential wall along a second diameter that is larger than the first diameter and smaller than the outside diameter of the second end face.

19. The electroacoustic transducer device according to claim 18 , wherein the plurality of slots are arranged so that the first slot portion of one slot, among the plurality of slots, and the second slot portion of a neighboring slot, among the plurality of slots, that neighbors the one slot, partly overlap in the circumferential direction.
