Abstract

Headphones including a sound output unit, a processing unit, a memory unit, a lighting unit, and a detection unit are provided. The sound output unit is configured to output sound. The memory unit is configured to store a program. The lighting unit is configured to emit light in response to a signal supplied from the processing unit. The detection unit is configured to obtain detection information and supply a detection signal corresponding to the detection information to the processing unit. The processing unit is configured to read out the program, carry out an operation using the detection signal and the program, and supply a signal corresponding to an operation result to the lighting unit.

Claims

1. Headphones comprising:

a sound output unit;

a processing unit;

a memory unit;

a lighting unit; and

a detection unit,

wherein the sound output unit is configured to output sound,

wherein the memory unit is configured to store a program,

wherein the lighting unit is configured to emit light in response to a signal supplied from the processing unit,

wherein the detection unit is configured to obtain detection information and supply a detection signal corresponding to the detection information to the processing unit, and

wherein the processing unit is configured to read out the program, carry out an operation using the detection signal and the program, and supply a signal corresponding to an operation result to the lighting unit.

2. The headphones according to claim 1,

wherein the detection unit comprises a photodetector unit, and

wherein the photodetector unit is configured to supply a detection signal corresponding to a quantity of detected light to the processing unit.

3. The headphones according to claim 2, wherein the processing unit is configured to make the lighting unit emit light when the quantity is smaller than a reference quantity.

4. The headphones according to claim 2, wherein the processing unit is configured to make the lighting unit emit light at a first luminance when the quantity is smaller than a reference quantity and make the lighting unit emit light at a second luminance different from the first luminance when the quantity is larger than the reference quantity.

5. The headphones according to claim 1,

wherein the detection unit comprises an attitude detection unit, and

wherein the attitude detection unit is configured to supply a detection signal corresponding to detected change in attitude to the processing unit.

6. The headphones according to claim 5, wherein the processing unit is configured to make the lighting unit blink when the detected change in attitude is larger than a reference quantity.

7. The headphonew according to claim 1, further comprising a biological sensor,

wherein the biological sensor is configured to obtain biological information and supply a detection signal corresponding to the biological information to the processing unit.

8. The headphones according to claim 7, wherein the processing unit is configured to stop the sound output unit from outputting sound when the biological sensor obtains no biological information.

9. The headphones according to claim 1, further comprising a power supply unit,

wherein the power supply unit comprises a power storage device and an antenna, and

wherein the power supply unit is configured to charge the power storage device wirelessly with the antenna.

10. The headphones according to claim 1, further comprising an external connection terminal,

wherein the processing unit is supplied with a sound signal from an external device that is connected to the external connection terminal with a wire.

11. The headphones according to claim 1, further comprising a housing,

wherein the sound output unit and the lighting unit are located inside the housing,

wherein the sound output unit outputs sound to an outside of the housing through a first surface of the housing, and

wherein the lighting unit emits light to the outside of the housing through a second surface of the housing.

12. The headphones according to claim 1, further comprising a band that can be worn on a human body,

wherein the band comprises the lighting unit.
