Abstract

A portable sound equipment having a body curved in C-shape, the body including an elastic part, an earbud holder provided to the body, an earbud detachably attached to the earbud holder, the earbud including a sound output module configured to output sound, a main board situated within the body, the main board configured to control the sound output module by being connected to the earbud, a sound cable connecting the earbud and the main body, a rotation module located within the body between an end portion of the body and main board, the rotation module configured to have the sound cable wound on an outer circumference thereof, a bridge coupled with the body to cover one surface of the rotation module, a flexible board disposed along the bridge and having one side connected to the main board and another side coupled to a microphone.

First claim

What is claimed is:

1 . A portable sound equipment, comprising:
a body including an elastic part; a metal case coupled at an outer side of the body; an earbud holder located at the body; an earbud detachably seated on the earbud holder, the earbud including a sound output module configured to output sound; a main board located within the body, the main board being connected to the earbud to control the sound output module; a sound cable connecting the main board to the earbud; a wireless communication unit installed at the main board; an antenna pattern connected to the wireless communication unit, the antenna pattern being configured to transceive a wireless signal; and a member having a non-conductive material, the member being inserted between the antenna pattern and the metal case.

2 . The portable sound equipment of claim 1 , wherein the member is located in an antenna hole formed in the body.

3 . The portable sound equipment of claim 1 , wherein the member comprises a non-conductive elastic gasket and conductive materials located on both sides of the non-conductive elastic gasket.

4 . The portable sound equipment of claim 1 , wherein a first end of the antenna pattern is connected to the wireless communication unit and a second end is connected to the member.

5 . The portable sound equipment of claim 1 , wherein the body comprises a case,
wherein the main board and the sound cable are installed in the case, and wherein the member comprises a portion of the case that is thinner than the rest of the case.

6 . The portable sound equipment of claim 1 , wherein the member is located closest to a gap between the antenna pattern and the metal case.

7 . The portable sound equipment of claim 1 , wherein, when the body is worn on a user's neck, the metal case is disposed in a direction away from user's neck.

8 . The portable sound equipment of claim 1 , further comprising a rotation module located within the body between an end portion of the body and the main board, the rotation module being configured to allow the sound cable to be wound on an outer circumference of the rotation module,
wherein the antenna pattern comprises a flexible board located to overlap the rotation module.

9 . The portable sound equipment of claim 1 , further comprising first and second microphones located on a first end portion of the body, the first and second microphones being spaced apart from each other by a prescribed distance in a length direction of the body,
wherein, when a sound level collected by the first and second microphones is greater than a reference value, the main board receives an input of sound from the first microphone only, and wherein, when the sound level collected by the first and second microphones is smaller than the reference value, the main board receives an input of sound from both of the first and second microphones.

10 . The portable sound equipment of claim 1 , wherein the earbud comprises:
an earbud housing having a sound output module located therein, the earbud housing having a curved surface; a sound hole formed in a first side of the earbud housing; and a cable holder projecting from a second side of the earbud housing, the cable holder being coupled with the sound cable, and wherein the earbud holder further comprises:
a seating part having a curved surface corresponding to a shape of the earbud housing; and
a cable hole formed in the seating part to allow the sound cable to pass therethrough.

11 . The portable sound equipment of claim 10 , wherein the seating part comprises:
a first portion configured to contact said second side of the earbud housing; a second portion extending from the first portion along an extending direction of the body toward a user's neck when being worn by the user; and a third portion extending along the extending direction of the body from the first portion, the third portion configured to contact the second portion in a front direction facing a front side of the user when being worn by the user, and wherein the cable hole is formed in an edge where the first, second and third portions meet one another.

12 . A portable sound equipment, comprising:
a body including an elastic part; a metal case coupled at an outer side of the body; an earbud holder located at the body; an earbud detachably seated on the earbud holder, the earbud including a sound output module configured to output sound; a main board located within the body, the main board being connected to the earbud to control the sound output module; a sound cable connecting the main board to the earbud; an antenna pattern connected to the main board, the antenna pattern being configured to transceive a wireless signal; and an antenna connecting part includes conductive material and configured to connect the antenna pattern and the metal case by penetrating the body.

13 . The portable sound equipment of claim 12 , wherein the body comprises:
an elastic band including elastic material; and a pair of housings connected to opposite ends of the elastic band, and wherein the elastic band includes:
a memory alloy having a wire shape;
a pair of connecting parts coupled to opposite end portions of the memory alloy; and
a deformable, first covering part configured to enclose the memory alloy and a portion of each of the connecting parts.

14 . The portable sound equipment of claim 13 , further comprising:
a signal line configured to transceive a signal, the signal line being between the pair of housings; and a second covering part configured to cover the memory alloy and a portion of the signal line, and placed inside of the first covering part.

15 . The portable sound equipment of claim 13 , wherein the opposite end portions of the memory alloy are each bent in a hook shape to be locked to a corresponding connecting part of the pair of connecting parts.

16 . The portable sound equipment of claim 13 , further comprising:
an upper case covering a first side of a part of the pair of connecting parts; a plurality of locking holes formed at the part of the pair of connecting parts; a plurality of screws coupling the connecting part and the upper case through the locking holes; and a lower case covering a second side of the part of the pair of connecting parts.

17 . The portable sound equipment of claim 16 , further comprising:
a signal line configured to transceive a signal, the signal line being between the pair of housings; and a signal line receiving part in each of the housings configured to receive the signal line, the signal line being separated from the locking holes.

18 . The portable sound equipment of claim 17 , wherein the signal line receiving part comprises a first portion wider than a thickness of the signal line and a second portion corresponding to the thickness of the signal line, and
wherein the first portion and the second portion are alternatingly formed.

19 . The portable sound equipment of claim 12 , further comprising first and second microphones located on a first end portion of the body, the first and second microphones being spaced apart from each other by a prescribed distance in a length direction of the body.

20 . The portable sound equipment of claim 19 , wherein the first and second microphones are located on one side of the first end portion of the body,
