Abstract

A sounding body is included in an audio reproduction device mounted on a mobile device. At least a part of the sounding body also serves as at least a part of one of an emblem, a horn section, and a mirror section of the mobile device.

First claim

What is claimed is:

1. A sounding body included in an audio reproduction device for use with a mobile device, the sounding body comprising:
a vibrating body;
a voice coil coupled to a rear surface of the vibrating body directly;
a magnetic circuit having a magnetic gap into which the voice coil is inserted; and
a frame including a bottom coupled to the magnetic circuit and an upper part supporting the vibrating body with respect to the magnetic circuit, and
a resin section coupled to an outer peripheral surface of the vibrating body and an inner peripheral surface of an opening of an exterior member of the mobile device such that the resin section attaches the vibrating body to the exterior member, and being more apt to deform than the vibrating body,
wherein the vibrating body includes an emblem portion which serves as an emblem of the mobile device, and the emblem portion is mounted on at least one of a front surface, side surface, and rear surface of the exterior member of the mobile device,
the upper part of the frame is fixed to a rear surface of the exterior member of the mobile device,
the emblem portion of the vibrating body is located at an outer side of the upper part of the frame.

2. An audio reproduction device for use with a mobile device, the audio reproduction device comprising:
an amplifier configured to amplify a sound source signal; and
the sounding body of claim 1 further configured to reproduce a signal amplified by the amplifier.

3. A mobile device comprising:
an audio reproduction device including:
an amplifier configured to amplify a sound source signal; and
the sounding body of claim 1 further configured to reproduce a signal amplified by the amplifier;

a sound source configured to supply the sound source signal to the amplifier of the audio reproduction device; and
a main body having the audio reproduction device and the sound source.

4. The sounding body according to claim 1 ,
wherein an outer surface of the exterior member of the mobile device and an outer face of the emblem portion are not covered with the resin section.

5. A sounding body included in an audio reproduction device for use with a mobile device, the sounding body comprising:
a vibrating body;
a voice coil coupled to a rear surface of the vibrating body directly;
a magnetic circuit having a magnetic gap into which the voice coil is inserted; and
a frame including a bottom coupled to the magnetic circuit and an upper part supporting the vibrating body with respect to the magnetic circuit, and
an elastic body coupled to an outer peripheral surface of the vibrating body and an inner peripheral surface of an opening of an exterior member of the mobile device such that the elastic body attaches the vibrating body to the exterior member,
wherein the vibrating body includes an emblem portion which serves as an emblem of the mobile device, and the emblem portion is mounted on at least one of a front surface, side surface, and rear surface of the exterior member of the mobile device,
the upper part of the frame is fixed to a rear surface of the exterior member of the mobile device,
the emblem portion of the vibrating body is located at an outer side of the upper part of the frame.

6. The sounding body according to claim 5 ,
wherein an outer surface of the exterior member of the mobile device and an outer face of the emblem portion are not covered with the elastic body.

7. A sounding body included in an audio reproduction device for use with a mobile device, the sounding body comprising:
a vibrating body;
a diaphragm acoustically coupled to a rear surface of the vibrating body via a cavity and apart from the vibrating body so that the vibrating body and the diaphragm do not contact each other;
a voice coil coupled to the diaphragm directly;
a magnetic circuit having a magnetic gap into which the voice coil is inserted; and
a frame including a bottom coupled to the magnetic circuit and an upper part supporting the vibrating body with respect to the magnetic circuit,
wherein the vibrating body serves as an emblem mounted on at least one of a front surface, side surface, and rear surface of an exterior member of the mobile device, and
the upper part of the frame and an outer part of the diaphragm are fixed to a rear surface of the exterior member of the mobile device.

8. The sounding body according to claim 7 , further comprising
an elastic body disposed between an outer periphery of the vibrating body and an inner periphery of an opening of the exterior member of the mobile device such that the elastic body attaches the vibrating body to the exterior member.

9. A sounding body included in an audio reproduction device for use with a mobile device, the sounding body comprising:
a vibrating body;
a voice coil coupled to a rear surface of the vibrating body directly;
a magnetic circuit having a magnetic gap into which the voice coil is inserted;
a frame including a bottom coupled to the magnetic circuit and an upper part supporting the vibrating body with respect to the magnetic circuit; and
an elastic body coupled to an outer peripheral surface of the vibrating body and an inner peripheral surface of an opening of an exterior member of the mobile device such that the elastic body attaches the vibrating body to be flush with the exterior member,
wherein the vibrating body serves as an emblem mounted on at least one of a front surface, side surface, and rear surface of the exterior member of the mobile device, and
an outer surface of the exterior member of the mobile device and an outer face of the emblem portion are not covered with the elastic body.

10. The sounding body according to claim 9 ,
wherein an outer surface of the exterior member of the mobile device and an outer face of the vibrating body are not covered with the elastic body.
