Abstract

A mobile terminal device includes a housing formed with an opening, a base plate provided inside the housing and having an audio component attached thereon, a cushion part provided around the opening of an inside wall surface of the housing, a frame part that includes a face near a surface of the audio component and forms an audio path between the audio component and the opening, one end portion near the face of the frame part being attached to the base plate, and another end portion abutting the inside wall surface of the housing via the cushion part.

Claims

1. A mobile terminal device, comprising:

a housing formed with an opening;

a base plate provided inside the housing and having an audio component attached thereon;

a cushion part provided around the opening of an inside wall surface of the housing; and

a frame part that includes a face near a surface of the audio component and forms an audio path between the audio component and the opening, one end portion near the face of the frame part being attached to the base plate, and another end portion abutting the inside wall surface of the housing via the cushion part.

2. The mobile terminal device according to claim 1, wherein the frame part is attached to the base plate with double-sided adhesive tape.

3. The mobile terminal device according to claim 1, wherein the cushion part is attached to the inside wall surface of the housing with double-sided adhesive tape.

4. The mobile terminal device according to claim 1, wherein the frame part includes:

an audio section that forms an air chamber around the opening by abutting the inside wall surface of the housing via the cushion part, and

a compartment that is connected to the audio section through a through hole formed in a bottom face of the audio section, and encloses the audio component by attaching the one end portion near the face of the frame part to the base plate.

5. The mobile terminal device according to claim 4, wherein the compartment seals an area around the audio component except for the through hole that opens near a sound perception part provided in the audio component.

6. The mobile terminal device according to claim 1, wherein the cushion part includes foamable resin that deforms under pressure.

7. A method for assembling a mobile terminal device, the method comprising:

providing a housing with an opening;

attaching a base plate, having an audio component, inside the housing;

attaching a cushion part around the opening of an inside wall surface of the housing; and

providing a frame part that includes a face near a surface of the audio component and forms an audio path between the audio component and the opening, one end portion near the face of the frame part being attached to the base plate, and another end portion abutting the inside wall surface of the housing via the cushion part.

8. The method of assembling the mobile terminal device according to claim 7, wherein the frame part is attached to the base plate with double-sided adhesive tape.

9. The method of assembling the mobile terminal device according to claim 7, wherein the cushion part is attached to the inside wall surface of the housing with double-sided adhesive tape.

10. The method of assembling the mobile terminal device according to claim 7, wherein the frame part includes:

an audio section that forms an air chamber around the opening by abutting the inside wall surface of the housing via the cushion part, and

a compartment that is connected to the audio section through a through hole formed in a bottom face of the audio section, and encloses the audio component by attaching the one end portion near the face of the frame part to the base plate.

11. The method of assembling the mobile terminal device according to claim 10, wherein the compartment seals an area around the audio component except for the through hole that opens near a sound perception part provided in the audio component.

12. The method of assembling the mobile terminal device according to claim 7, wherein the cushion part includes foamable resin that deforms under pressure.
