Abstract

There is disclosed a portable sound equipment comprising a neckband wire configured to wrap a predetermined region of a user's neck; a main body coupled to one end of the neckband wire; a first printed circuit board disposed on an upper or lower surface of the main body; a flat bracket disposed on the first printed circuit board and having one surface which contacts with the first printed circuit board; a lateral bracket coupled to a lateral surface of the flat bracket; a second printed circuit board supported to the lateral bracket and toward a lateral surface of the main body; and a side button disposed on the second printed circuit board and exposed outside the lateral surface of the main body.

First claim

What is claimed is:

1. A portable sound equipment comprising:
a neckband wire configured to wrap a predetermined region of a user's neck;
a main body coupled to one end of the neckband wire;
a first printed circuit board disposed on an upper or lower surface of the main body;
a flat bracket disposed on the first printed circuit board and having one surface which contacts with the first printed circuit board;
a lateral bracket coupled to a lateral surface of the flat bracket;
a second printed circuit board supported to the lateral bracket and toward a lateral surface of the main body; and
a side button disposed on the second printed circuit board and exposed outside the lateral surface of the main body.

2. The portable sound equipment of claim 1 , further comprising:
a first sealing member configured to cover an inner surface of the side button and contact with the lateral surface of the main body by being compressed by the lateral bracket.

3. The portable sound equipment of claim 1 , further comprising:
a battery disposed on the other surface of the flat bracket,
wherein the flat bracket spaces the battery a preset distance apart from the first printed circuit board.

4. The portable sound equipment of claim 3 , wherein an opening is formed in a preset region of the flat bracket.

5. The portable sound equipment of claim 1 , further comprising:
a fastening screw hole formed in each of the flat bracket, the first printed circuit board and the surface of the main body where the first printed circuit board is disposed; and
a first screw configured to fasten the flat bracket, the first printed circuit board and the main body to each other, after penetrating the fastening screw hole.

6. The portable sound equipment of claim 1 , further comprising:
a coupling unit provided in one end of the neckband wire and secured to an inside of the end of the main body;
a waterproof rib projected along an inner circumference of the end of the main body; and
a waterproof groove provided in the coupling unit and configured to be fastened to the waterproof rib.

7. The portable sound equipment of claim 6 , further comprising:
a coupling hole formed in the coupling unit; and
a projection projected from one region of the main body, corresponding to the coupling hole,
wherein the fastening structure between the waterproof rib and the waterproof groove is further inside toward the first printed circuit board than the coupling structure between the coupling hole and the projection.

8. The portable sound equipment of claim 6 , further comprising:
a first connection leading wire projected from one end of a waterproof region formed in the coupling unit and configured to be coupled to the first printed circuit board,
wherein a non-waterproof region toward the neckband wire and a waterproof region toward the first printed circuit board are distinguished from each other with respect to a boundary of the coupling region between the waterproof rib and the waterproof groove.

9. The portable sound equipment of claim 1 , further comprising:
a first connection wire coupled to the first printed circuit board after penetrating the neckband wire;
a wire tube in which the first connection leading wire is mounted; and
a coupling unit coupled to one end of the wire tube and fixed in one end of the main body,
wherein the neckband wire comprises,
a first wire portion covering and coupled to the wire tube and a region of the coupling unit; and
a second wire portion coupled to a region which contacts with the user's neck.

10. The portable sound equipment of claim 9 , wherein the coupling unit is double-injection molded in the wire tube and one region of the coupling, and
the second wire portion is double-injection-molded in the first wire portion.

11. The portable sound equipment of claim 9 , wherein the first wire portion comprises TPU (thermoplastic Poly Urethane); and
a pattern engraved or embossed on one region of the second wire.

12. The portable sound equipment of claim 1 , further comprising:
an I/O port provided in the main body;
a waterproof cap configured to selectively expose the I/O port to an outer surface of the main body;
a second sealing member coupled to an inner surface of the waterproof cap; and
a waterproof band provided along an outer surface of the second sealing member.
