Abstract

Provided is a speaker fall prevention structure, which includes a speaker device formed by housing a speaker unit in a housing independent of a main appliance, a speaker attaching part provided to the main appliance to allow the speaker device to be attached, an attached part facing the speaker attaching part in the speaker device, a fall prevention wire set between the speaker device and the main appliance, and a fastening member for attaching the attached part to the speaker attaching part. Using the fastening member, a first end of the fall prevention wire is fastened and fixed to the main appliance along with the attached part.

Claims (34)

1. A speaker fall prevention structure for preventing a fall of a speaker device formed by housing a speaker unit in a housing independent of a main appliance, comprising:

a speaker attaching part provided on the main appliance to allow the speaker device to be attached;

an attached part facing the speaker attaching part in the speaker device;

a fall preventing wire set between the speaker device and the main appliance; and

a fastening member for attaching the attached part to the speaker attaching part,

wherein, using the fastening member, a first end of the fall preventing wire is fastened and fixed to the main appliance along with the attached part, and a second end of the fall preventing wire is located at a position almost identical to the center of gravity of the speaker device and is fixed to the speaker device.

2. The speaker fall prevention structure according to claim 1 , wherein a wire attaching part of the speaker device to which the second end of the fall preventing wire is attached is formed on a vertical middle portion of the speaker device.

3. The speaker fall prevention structure according to claim 2 , wherein the housing of the speaker device is dividedly made up of a first housing forming a sound outputting part and a second housing connected to a rear of the first housing, at least one of the first and second housings is formed of a plastic molding, and the attached part is integrally formed with the housing.

4. The speaker fall prevention structure according to claim 2 , wherein the fall preventing wire is configured so that the first end thereof which is fastened and fixed to the main appliance extends to follow an outer surface of the housing of the speaker device, and the second end thereof is fixed to the speaker unit of the speaker device.

5. The speaker fall prevention structure according to claim 1 , wherein the housing of the speaker device is dividedly made up of a first housing forming a sound outputting part and a second housing connected to a rear of the first housing, at least one of the first and second housings comprises a plastic molding, and the attached part is integrally formed with the housing.

6. The speaker fall prevention structure according to claim 5 , wherein the fall preventing wire is configured so that the first end thereof which is fastened and fixed to the main appliance extends to follow an outer surface of the housing of the speaker device, and the second end thereof is fixed to the speaker unit of the speaker device.

7. The speaker fall prevention structure according to claim 1 , wherein the fall preventing wire is configured so that the first end thereof which is fastened and fixed to the main appliance extends to follow an outer surface of the housing of the speaker device, and the second end thereof is fixed to the speaker unit of the speaker device.

8. The speaker fall prevention structure according to claim 1 , wherein the second end of the fall preventing wire is fixed at a center of a rear end of the speaker unit.

9. A speaker fall prevention structure for preventing a fall of a speaker device formed by housing a speaker unit in a housing independent of a main appliance, comprising:

a speaker attaching part provided on the main appliance to allow the speaker device to be attached;

an attached part facing the speaker attaching part in the speaker device, the attached part including an upper attached part and a lower attached part;

a fall preventing wire set between the speaker device and the main appliance; and

a fastening member for attaching the attached part to the speaker attaching part,

wherein, using the fastening member, the speaker device is fixed to the main appliance at the upper attached part and the lower attached part of the attached part, and the fall preventing wire is fixed to the upper attached part and is fixed to the main appliance.

10. The speaker fall prevention structure according to claim 9 , wherein a wire attaching part of the speaker device to which a second end of the fall preventing wire is attached is formed on a vertical middle portion of the speaker device.

11. The speaker fall prevention structure according to claim 10 , wherein the housing of the speaker device is dividedly made up of a first housing forming a sound outputting part and a second housing connected to a rear of the first housing, at least one of the first and second housings comprises a plastic molding, and the attached part is integrally formed with the housing.

12. The speaker fall prevention structure according to claim 10 , wherein the fall preventing wire is configured so that a first end thereof which is fastened and fixed to the main appliance extends to follow an outer surface of the housing of the speaker device, and the second end thereof is fixed to the speaker unit of the speaker device.

13. The speaker fall prevention structure according to claim 9 , wherein the housing of the speaker device is dividedly made up of a first housing forming a sound outputting part and a second housing connected to a rear of the first housing, at least one of the first and second housings comprises a plastic molding, and the attached part is integrally formed with the housing.

14. The speaker fall prevention structure according to claim 13 , wherein the fall preventing wire is configured so that a first end thereof which is fastened and fixed to the main appliance extends to follow an outer surface of the housing of the speaker device, and a second end thereof is fixed to the speaker unit of the speaker device.

15. The speaker fall prevention structure according to claim 9 , wherein the fall preventing wire is configured so that a first end thereof which is fastened and fixed to the main appliance extends to follow an outer surface of the housing of the speaker device, and a second end thereof is fixed to the speaker unit of the speaker device.

16. The speaker fall prevention structure according to claim 9 , wherein a second end of the fall preventing wire is fixed at a center of a rear end of the speaker unit.

17. A structure comprising:

a speaker device comprising:

a housing comprising a rear protruding part including a hole; and

a speaker unit formed in the housing and including a stud fixed to a rear end of the speaker unit, a threaded hole in the stud being aligned with the hole in the rear protruding part and being formed at substantially a center of gravity of the speaker device;

an attaching member formed on the rear protruding part and including a hole for accommodating a first fastening member for fastening the speaker device to an appliance; and

a wire comprising:

a first end including a first washer for connecting the wire to the attaching member, the first washer including a hole for accommodating the first fastening member; and

a second end including a second washer for connecting the wire to the rear protruding part of the housing, the second washer including a hole which is aligned with the threaded hole in the stud and the hole in the rear protruding part, for accommodating a second fastening member for fastening the second washer to the stud.
