Abstract

A wearable speaker comprises: a speaker module equipped with a audio output unit; and a fixing module magnetically coupled to the speaker module, wherein the speaker module includes: a speaker housing having a sound hole formed on a first surface; the audio output unit positioned inside the sound hole; a battery positioned inside the speaker housing; and a first magnet disposed adjacent to a second surface of the speaker housing, and the fixing module includes a second magnet coupled to the first magnet. The wearable speaker can be easily attached to and detached from a user's clothes and thus can be attached to existing clothes and detached when washing the clothes, thereby improving usability.

First claim

What is claimed is:

1 . A wearable speaker, comprising:
a speaker module having an audio output unit mounted thereon; and a fixing module coupled to the speaker module by magnetic force, wherein the speaker module comprises a speaker housing having a sound hole formed in a first surface, the audio output unit positioned inside the sound hole, a battery positioned inside the speaker housing, and a first magnet disposed adjacent to a second surface of the speaker housing and wherein the fixing module comprises a second magnet coupled to the first magnet.

2 . The wearable speaker of claim 1 , further comprising a first magnetic shielding plate disposed on a first surface of the first magnet.

3 . The wearable speaker of claim 2 , wherein the first magnetic shielding plate further comprises a side part covering a side surface of the first magnet.

4 . The wearable speaker of claim 1 , further comprising a second magnetic shielding plate disposed on a second surface of the second magnet.

5 . The wearable speaker of claim 1 , further comprising a second magnetic shielding plate disposed on a second surface of the second magnet.

6 . The wearable speaker of claim 1 , wherein the first magnet has a ring shape and comprises an inner pole and an outer pole different from the inner pole.

7 . The wearable speaker of claim 1 , wherein the first magnet has a ring shape and comprises a first pole positioned inside and a second pole positioned at an outer circumference of the first pole and forming a polarity opposite to that of the first pole.

8 . The wearable speaker of claim 1 , wherein a plurality of the first magnets are disposed along a circumference of the wearable speaker and wherein the first magnet comprises a first pole positioned inside and a second pole positioned outside.

9 . The wearable speaker of claim 8 , wherein the first pole of the first magnet has a polarity opposite to that of the first pole of the neighboring first magnet.

10 . The wearable speaker of claim 1 , the speaker module comprising:
a power receiver charging the battery from a charger disposed on the second surface: and a power transmitter transmitting power to a speaker module stacked on the first surface.

11 . The wearable speaker of claim 10 , wherein the power receiver comprises a charging terminal disposed on the second surface of the speaker housing and configured to charge the battery and wherein the power transmitter comprises a transmitting terminal disposed on the first surface of the speaker housing and configured to provide power of the battery.

12 . The wearable speaker of claim 10 , wherein the power receiver comprises a charging coil disposed adjacent to the second surface of the speaker housing and configured to charge the battery and wherein the power transmitter comprises a transmitting coil disposed adjacent to the first surface of the speaker housing and configured to transmit power of the battery.

13 . The wearable speaker of claim 10 , further comprising a controller configured to activate the power transmitter based on a charged amount of the battery greater than or equal to a reference value.

14 . The wearable speaker of claim 10 , wherein the speaker module further comprises a third magnet disposed adjacent to the first surface and attached to the first magnet of the speaker module stacked on the first surface.
