Claims (59)

1. A sound reproduction device comprising a wireless earphone, and a cradle that houses the wireless earphone, wherein

the cradle includes:

a rechargeable battery for charging the wireless earphone; and

a touch panel that functions as an input/output interface for the wireless earphone,

the wireless earphone includes a sensor unit that acquires sensor information that contains at least either motion information or biological information of a user, and

the cradle further includes a data processing unit that receives the sensor information from the sensor unit and performs display based on the sensor information on the touch panel.

2. The sound reproduction device according to claim 1 ,

wherein the wireless earphone includes a left-ear earphone and a right-ear earphone, and

the left-ear earphone and the right-ear earphone are configured so as to be independent from each other.

3. The sound reproduction device according to claim 1 ,

wherein the cradle includes a data transfer port for connection with the wireless earphone housed in the cradle.

4. The sound reproduction device according to claim 1 ,

wherein the wireless earphone includes a microphone.

5. The sound reproduction device according to claim 4 ,

wherein a voice instruction is received through the microphone.

6. The sound reproduction device according to claim 1 ,

wherein the wireless earphone further includes a position acquisition unit that acquires coordinate information of a current position.

7. The sound reproduction device according to claim 1 ,

wherein the wireless earphone further includes a voice communication unit that performs voice communication with another terminal.

8. The sound reproduction device according to claim 1 ,

wherein the data processing unit updates display based on the sensor information in real time on the touch panel.

9. The sound reproduction device according to claim 1 ,

wherein the sensor unit acquires the sensor information from the user's right and left ears, and

the data processing unit displays the sensor information acquired from the right and left ears, in such a manner that the sensor information acquired from the right ear and the sensor information acquired from the left ear can be compared on the touch panel.

10. A sound reproduction device comprising a wireless earphone, and a cradle that houses the wireless earphone, wherein

the cradle includes:

a rechargeable battery for charging the wireless earphone; and

a touch panel that functions as an input/output interface for the wireless earphone,

the wireless earphone further includes an equalizer processing unit that adjusts acoustic frequency characteristics of the wireless earphone, and
