FIG. 2 is a flowchart of a process performed by the mobile phone 100 and the toilet room device 110 when the mobile phone 100 in the toilet room receives an incoming call and the user responds to the incoming call in the first embodiment.
Step 201: There is an incoming call to the mobile phone 100 in the toilet room.
Step 202: The user presses the response button and goes off-hook. If the mobile phone 100 is in the corresponding toilet room, the pairing between the Bluetooth unit 104 of the mobile phone 100 and the Bluetooth unit of the toilet room device is established by the time the call is started.
Step 203: The call monitoring unit 102, which monitors the mobile phone control unit 101 and detects that the incoming call is off-hooked, determines whether the Bluetooth unit 104 is paired with a toilet room device having a sound muting function. Determine.
Step 204: If not paired with the corresponding toilet room device, proceed to Step 205. When there is a corresponding toilet room device, the process proceeds to step 206.
Step 205: The mobile phone 100 stops the background sound processing and performs only normal call processing.
Step 206: The mobile phone 100 performs the normal call processing and simultaneously controls the background sound control unit 103, and instructs the toilet room device 110 to reproduce the background sound for muting through the Bluetooth unit 104.
Step 207: The toilet room control unit 111 that has received an instruction to reproduce the background sound from the mobile phone 100 via the Bluetooth unit 113 of the toilet room device 110 instructs the background sound generation unit 112 to output the background sound.
Step 208: The background sound generation unit 112 reads the background sound data from the background sound storage unit 114, converts it into sound, and outputs it from the speaker 115.

  FIG. 2 shows a configuration in which the toilet room device 110 is instructed to reproduce background sound in response to an incoming call to the mobile phone 100 in the toilet room. However, it is possible to have a configuration in which the toilet room device 110 is instructed to reproduce the background sound even when the user makes a call from the mobile phone 100 in the toilet room. In this case, in addition to step 201 and step 202, the process of the call monitoring unit 102 adds a process of detecting that the mobile phone control unit 101 has made a call and proceeding to step 203.

FIGS. 3A and 3B are flowcharts of processing executed when the mobile phone 100 and the toilet room device 110 each finish outputting the background sound in the first embodiment.
The end processing flow of the mobile phone 100 shown in FIG. 3A is as follows.
Step 211: Corresponds to step 206 in FIG. The mobile phone 100 that has started the call instructs the paired toilet room device 110 to reproduce the background sound.
Step 212: The call monitoring unit 102 checks the mobile phone control unit 101 to determine whether a call is being made. When the call monitoring unit 102 detects that the mobile phone 100 is on-hook or the connection destination ends the call, the process proceeds to step 215. If the call is continued, the process proceeds to step 213 to determine the next condition.
Step 213: The call monitoring unit 102 checks the Bluetooth unit 104 to determine whether or not the link with the toilet room device 110 is maintained. When the user leaves the toilet room, the link with the toilet room device 110 is broken. When the call monitoring unit 102 detects that the link between the Bluetooth unit 104 and the toilet room device 110 has been disconnected, the process proceeds to step 216, and the process related to the background sound is terminated.
Step 214: The call monitoring unit 102 inspects the Bluetooth unit 104 and checks the intensity of the radio wave from the toilet room device 110. When the user leaves the toilet room and the distance from the toilet room device 110 increases, the received radio wave becomes weak. When the intensity of the received radio wave is equal to or lower than the predetermined value, it is considered that the user has left the toilet room, so the process proceeds to step 215 and the end process is performed. When the condition for ending the background sound is not satisfied, the process returns to step 212.
Step 215: The call monitoring unit 102 controls the background sound control unit 103 to instruct to cancel the background sound. Upon receiving this instruction, the background sound control unit 103 instructs the toilet room device 110 to stop the background sound via the Bluetooth unit 104.

Upon receiving the background sound playback instruction from the mobile phone 100 via the Bluetooth unit 113, the toilet room control unit 111 controls the background sound generation unit 112 and reads the background sound data stored in the background sound storage unit 114. The data is reproduced by the speaker 115. In addition, the toilet room control unit 111 sets a timer. The purpose of this timer is to respond to a user who only needs to play back for a certain period of time and to prevent the background sound from being played indefinitely due to failure to receive an end instruction sent by the mobile phone. This timer part can be omitted.
Step 222: The console of the toilet room device 110 is provided with a button for ending the background sound being reproduced. When the user determines that the background sound is not necessary, the background sound is canceled by operating the background sound end button. In step 222, the toilet room control unit 111 determines whether or not the background sound end button has been operated. When the end button is operated, the process proceeds to step 227 to end the background sound. The background sound end button and step 222 can be omitted.
Step 223: The toilet room control unit 111 determines whether or not the timer time set in Step 221 has elapsed. When the timer has expired, the process proceeds to step 227 to end the background sound.
Step 224: This process corresponds to step 213 in FIG. When the toilet room control unit 111 detects that the link between the Bluetooth unit 113 and the mobile phone 100 is disconnected, the process proceeds to step 227 to end the background sound.
Step 225: This process corresponds to step 215 in FIG. When the toilet room control unit 111 receives an end signal from the mobile phone 100 via the Bluetooth unit 113, the toilet room control unit 111 proceeds to step 227 and ends the background sound.
Step 226: Continue the background sound and return to Step 222.
Step 227: End the background sound. The toilet room device 110 initializes the internal state and waits for the next request from the mobile phone.
