Abstract

Disclosed is a wireless stereo headset. The wireless stereo headset includes a first headset including a speaker unit and a Bluetooth® enabled module, for converting sound signals received from a device, transmitting the sound signals into sounds and outputting the sounds, and a second headset including a speaker unit and a Bluetooth® enabled module, for selectively receiving a portion of the sound signals which are converted into sounds and outputting the sounds, thereby accomplishing mono sound by using the first headset according to a user'"'"'s request or achieving stereo sound by using the first and second headsets. The wireless stereo headset can perform voice communication by using only the first headset, while accomplishing stereo sounds by using both the first and second headsets, thereby using the wireless stereo headset to enjoy an improved sound quality.

Claims

1. A wireless stereo headset comprising:

a first headset including a speaker unit and a Bluetooth®

enabled module, for converting sound signals received from a device, transmitting the sound signals into first sounds and outputting the first sounds; and

a second headset including a speaker unit and a Bluetooth®

enabled module, for selectively receiving a portion of the sound signals which are converted into second sounds and outputting the second sounds, thereby achieving mono sound by using the first headset according to a user'"'"'s request or achieving stereo sound by using the first and second headsets.

2. The wireless stereo headset as claimed in claim 1, wherein the second headset receives through the first headset the portion of the sound signals output from the device and converts the portion of the sound signals into the second sounds to output the second sounds.

3. The wireless stereo headset as claimed in claim 1, wherein the second headset receives the portion of the sound signals transmitted from the device and converts the portion of the sound signals into the second sounds to output the second sounds.

4. The wireless stereo headset as claimed in claim 1, wherein the respective first and second headsets include a housing containing the speaker unit and a wearable frame surrounding at least a portion of and spaced apart from a periphery of the housing and having one end connected to the housing.

5. The wireless stereo headset as claimed in claim 1, wherein the first headset performs functions for transmitting and receiving signals to and from the device through the Bluetooth®

enabled module.

6. The wireless stereo headset as claimed in claim 1, wherein the device includes an audio device for playing sound media and the first headset further includes at least one key for playing the sound media, stopping the playing of the sound media, controlling volume of the sound media and selecting the sound media while performing a communication function with the audio device.

7. The wireless stereo headset as claimed in claim 1, wherein the respective first and second headsets include an interior battery and a jack connector for connection to an electric source for charging the interior battery.

8. The wireless stereo headset as claimed in claim 1, wherein the device includes a portable terminal providing a voice communication function, and the first headset includes a microphone unit for converting a user'"'"'s voice into electric signals and can enable voice communication by transmitting the electric signals to the portable terminal through the Bluetooth®

enabled module.

9. The wireless stereo headset as claimed in claim 8, wherein the first headset includes a housing containing the speaker unit and a transmitter extending from an outer peripheral surface of the housing, the microphone unit being disposed in the transmitter.

10. The wireless stereo headset as claimed in claim 9, wherein the transmitter extends retractably from the housing.

11. The wireless stereo headset as claimed in claim 8, wherein the first headset further includes an on/off key for starting and ending the voice communication.

12. The wireless stereo headset as claimed in claim 8, wherein the first headset further includes a luminous element that flickers according to an extent of reception of signals transmitted and received to and from the portable terminal.

13. A wireless stereo headset comprising:

a first headset including a Bluetooth®

enabled module and a speaker unit, for outputting and playing a first sound signal if only the first sound signal is received, and transmitting a second sound signal through Bluetooth®

enabled communication if first and second sound signals are received;

a second headset including a Bluetooth®

enabled module and a speaker unit, for outputting and playing the second sound signal received from the first headset; and

a portable terminal for transmitting the first and second sound signals corresponding to right and left channels, respectively, of a corresponding music file through the Bluetooth®

enabled communication to the first headset according to a user'"'"'s request, playing the music file and transmitting corresponding voice signals through the Bluetooth®

enabled communication to the first headset during a voice communication.

14. A wireless stereo headset comprising:

a first headset including a Bluetooth®

enabled module and a speaker unit, for outputting and playing a first sound signal when the first sound signal is received;

a second headset including a Bluetooth®

enabled module and a speaker unit, for outputting and playing a second sound signal when the second sound signal is received; and

a portable terminal for transmitting the first sound signal corresponding to a right channel of corresponding music file through Bluetooth®

enabled communication to the first headset according to a user'"'"'s request, playing the music file while transmitting the second sound signal corresponding to a left channel of corresponding music file through the Bluetooth®

enabled communication to the second headset.
