## Abstract

A speaker frame, including: a vibration support portion supporting a vibrating body of a speaker; a magnet support portion arranged inside of said vibration support portion and supporting magnetic circuit portion of said speaker; and a plurality of connection beams connecting said vibration support portion and said magnet support portion, wherein the vibration support portion and the magnet support portion have a circular ring shape having the same major axis length and minor axis length, said plurality of connection beams are arranged radially centering on a central axis from said magnet support portion to said vibration support portion, the central axis being parallel to a direction of an acoustic radiation, and a length of one of said connection beams and a length of another connection beams are different from each other.

## Claims

### Claim 1

A speaker frame, comprising:
a vibration support portion including a vibrating body mounting portion for a vibrating body of a speaker, and a tubular portion connecting to the vibrating body mounting portion;
a magnet support portion arranged inside of the vibration support portion and supporting a magnetic circuit portion of the speaker; and
a plurality of connection beams connecting the vibration support portion and the magnet support portion,
wherein the plurality of connection beams contains a first connection beam connected to the vibration support portion at a connection portion, and a second connection beam connected to the vibration support portion at a portion opposite to the connection portion in a sound emitting direction.

### Claim 2 (depends on 1)

The speaker frame as claimed in claim 1,
wherein the first connection beam is connected to the vibrating body mounting portion of the vibration support portion.

### Claim 3 (depends on 1)

The speaker frame as claimed in claim 1,
wherein the second connection beam is connected to the tubular portion of the vibration support portion.

### Claim 4 (depends on 2)

The speaker frame as claimed in claim 2,
wherein the second connection beam is connected to the tubular portion of the vibration support portion.

### Claim 5 (depends on 4)

The speaker frame as claimed in claim 4,
wherein the second connection beam extends from an inner edge of the vibrating body mounting portion towards an inner circumferential face of the tubular portion, and connected to the inner circumferential face of the tubular portion.

### Claim 6 (depends on 4)

The speaker frame as claimed in claim 4, further comprising:
a projecting portion connecting the second connection beam and the vibrating body mounting portion, and formed on the tubular portion.

### Claim 7 (depends on 1)

The speaker frame as claimed in claim 1,
wherein the magnet support portion includes a damper mounting portion for mounting a damper on the speaker, and
wherein the first and second connection beams are connected to the damper mounting portion of the magnet support portion.

### Claim 8 (depends on 7)

The speaker frame as claimed in claim 7,
wherein the magnet support portion is arranged at a different position from the damper mounting portion along the central axis of the speaker, and includes a bottom portion at which the magnetic circuit portion of the speaker is attached.

### Claim 9 (depends on 1)

The speaker frame as claimed in claim 1,
wherein the tubular portion is formed into a cylinder-like shape.

### Claim 10 (depends on 1)

The speaker frame as claimed in claim 1,
wherein the tubular portion is connected to an outer edge of the vibrating body mounting portion.

### Claim 11

A speaker comprising:
a vibrating body;
a magnetic circuit portion; and
a speaker frame,
wherein the speaker frame includes:
a vibration support portion including a vibrating body mounting portion for a vibrating body of a speaker, and a tubular portion connecting to the vibrating body mounting portion;
a magnet support portion arranged inside of the vibration support portion and supporting the magnetic circuit portion of the speaker; and
a plurality of connection beams connecting the vibration support portion and the magnet support portion,
wherein the plurality of connection beams contains a first connection beam connected to the vibration support portion at a connection portion, and a second connection beam connected to the vibration support portion at a portion opposite to the connection portion in a sound emitting direction.
