1 is a flow chart of a method for controlling a volume of a television by a mobile phone according to a preferred embodiment.

2 is a functional block diagram of an audio device and a communication device according to a preferred embodiment.

The present embodiment provides a method of controlling the volume of an audio device with a communication device. When the communication device has a call, when the user presses the answer button, the communication device automatically sends a control signal to lower the volume of the audio device. When the user presses the hang up button to interrupt the call, the communication device automatically sends another message. Control the signal to restore the volume of the audio device. The audio device can be a television, a sound system, a computer, etc., and the communication device can be a mobile phone, a PDA, a landline phone, a PHS, or the like. The specific steps of the method are further illustrated by taking the mobile phone to control the volume of the television as an example.

As shown in FIG. 1 , it is a flow of a method for controlling a TV volume of a mobile phone according to a preferred embodiment. The method includes the following steps: Step S101 : The mobile phone receives an incoming call request and sends a reminder message, such as a ring alert or a vibration alert.

In step S103, the mobile phone responds to the user operation to generate an answering instruction, such as pressing a mobile phone answer button, or flipping the mobile phone's flip to automatically answer the action.

In step S105, the mobile phone sends an acceptance message according to the answering command to connect the phone.

Step S107, the mobile phone further generates a first control signal according to the answering command, and transmits the first control signal to the television. The transmission method can be electromagnetic wave or the same infrared signal as the remote control of the TV, and when the infrared signal is used, the television does not need to be changed.

In step S109, the television receives the first control signal and saves the current volume message.

In step S111, the television adjusts the volume to a preset size (including mute) according to the first control signal.

In step S113, the mobile phone responds to the user operation and generates a hang up command, such as pressing a mobile phone hang up button, or flipping the mobile phone's cover to automatically hang up.

In step S115, the mobile phone issues an on-hook command according to the hang up command to end the call.

Step S117, the mobile phone further generates a second control signal according to the hang up command, and transmits the second control signal to the television.

In step S119, the television receives the second control signal and restores the volume according to the stored volume information.

The television in step S109 receives the first control signal, and the step of saving the current volume information may be omitted. The subsequent television receives the second control signal, and adjusts the volume. Section to another preset size.

By the above mobile phone controlling the volume of the television, if the user calls the phone when the user calls, as long as the user answers the call, the volume of the television will be automatically reduced (including mute) to provide a better call to the user. The environment, while the user does not pick up or answer the phone does not affect watching TV. Further, after the user hangs up the phone, the TV volume is automatically restored, which saves the user from adjusting the volume of the TV to provide convenience for the user.

Please refer to FIG. 2 , which is a functional block diagram of the audio device 10 and the communication device 20 according to a preferred embodiment. The audio device 10 includes an audio signal generating unit 102, a sound output unit 104, a receiving unit 106, and a volume adjusting unit 108. The sound output unit 104 is configured to convert the audio signal provided by the audio signal generating unit 102 into a sound output. Such as the sound of TV programs on TV. The volume adjustment unit 108 is configured to adjust the size of the output volume of the sound output unit 104 according to the control signal received by the receiving unit 106.

The communication device 20 includes a communication unit 202, an operation unit 204, a status detection unit 206, an input detection unit 208, a signal generation unit 210, and a transmission unit 212.

The communication unit 202 is used for talking with other communication devices. The operation unit 204 controls the operation of the communication unit 202 according to a user operation, such as answering a call, hanging up a call, and the like.

The status detecting unit 206 detects the operation status message of the communication device 20 and supplies it to the signal generating unit 210.

The input detecting unit 208 detects an operation message of the operating unit 204 and supplies it to the signal generating unit 210.

The signal generating unit 210 generates a control signal for controlling the volume of the audio device 10 according to the working status message and the operation message, including: when the working status message is an incoming call status and the operation message is an answering operation, the first control signal is generated, and is sent by the transmitting unit 212. The audio device 10 is provided to adjust the volume of the audio device 10 to a preset size; when the working status message is the call state and the operation message is the hanging operation, the second control signal is generated and sent to the audio device 10 by the transmitting unit 212. To restore the volume of the audio device 10 to the size before adjustment, or to another preset size.

The transmitting unit 212 can transmit electromagnetic waves or infrared signals.

When the audio device 10 is controlled by the communication device 20, if the user answers the call, the volume of the audio device 10 will be automatically turned down or muted to provide a better communication environment for the user.
