Input device

Abstract

An input device of an electronic apparatus including an input detection unit which is provided on the electronic apparatus at a position that is difficult to be seen by a user who uses the input device, and which detects an input operation of the user; a movement distance detection unit that detects a movement distance of an input position over the input detection unit; and an action control unit that controls a predetermined action of the electronic apparatus based on the movement distance detected by the movement distance detection unit.

What is claimed is: 
     
         1 . An electronic apparatus comprising:
 an input detection unit, comprising a surface provided on the electronic apparatus, the input detection unit being configured to detect touch input of a user on the surface;   a movement detection unit configured to detect a movement distance and direction of the touch input along the surface of the input detection unit; and   a headphone comprising a housing on which the input detection unit and the movement detection unit are located.   
     
     
         2 . The electronic apparatus according to  claim 1 , further comprising:
 a transmitter configured to wirelessly transmit at least one first signal to a sound reproduction apparatus to initiate a connection between the electronic apparatus and the sound reproduction apparatus, and to transmit at least one second signal to the sound reproduction apparatus to control the sound reproduction apparatus; and   a receiver configured to wirelessly receive at least one third signal from the sound reproduction apparatus to establish the connection between the electronic apparatus and the sound reproduction apparatus;   wherein the transmitter is configured to wirelessly transmit as part of the at least one second signal an instruction to start or stop sound reproduction by the sound reproduction apparatus in response to receiving touch input of a user on the surface.   
     
     
         3 . The electronic apparatus according to  claim 2 , comprising:
 a lock setter configured to invalidate touch input to the input detection unit; and   a lock releaser configured to release a lock set by the lock setter.   
     
     
         4 . The electronic apparatus according to  claim 2 , comprising a power supply that is rechargeable via a charging terminal. 
     
     
         5 . The electronic apparatus according to  claim 2 , wherein wireless transmission and reception by the transmitter and the receiver, respectively, is performed using near field wireless communication. 
     
     
         6 . The electronic apparatus according to  claim 5 , wherein the near field wireless communication employs a Bluetooth protocol. 
     
     
         7 . The electronic apparatus according to  claim 2 , wherein the input detection unit is configured to detect a double tap input. 
     
     
         8 . The electronic apparatus according to  claim 2 , wherein the at least one first signal and the at least one third signal comprise address information for identifying the electronic apparatus or the sound reproduction apparatus. 
     
     
         9 . The electronic apparatus according to  claim 2 , wherein the sound reproduction apparatus comprises a smartphone. 
     
     
         10 . The electronic apparatus according to  claim 2 , wherein the input detection unit comprises a capacitive type touch sensor. 
     
     
         11 . The electronic apparatus according to  claim 2 , wherein the electronic apparatus comprises a speaker configured to output a sound signal corresponding to a signal received by the receiver, and the speaker is disposed to output the sound signal in a direction orthogonal to the surface. 
     
     
         12 . The electronic apparatus according to  claim 2 , comprising at least one power button configured to switch the electronic apparatus between ON and OFF states. 
     
     
         13 . The electronic apparatus according to  claim 2  wherein the housing comprises a speaker and at least one power button, the speaker being configured to output a sound signal according to a signal received by the receiver, the at least one power button being configured to switch the electronic apparatus between ON and OFF states.
