Electronic device and its volume control system and method

The present invention relates to the field of electronic technologies, and in particular, to an electronic device and a volume control system and method thereof.

With the development of science and technology, various household appliances continue to evolve, such as the development of television sets from CRT to LCD TVs and plasma TVs. With the innovation of household appliances, auxiliary equipment such as remote controls for home appliances have emerged. The increasing popularity of various household appliances has greatly enriched people's lives, and the remote control has also brought great convenience to people's lives.

The remote control generally uses infrared transmission signals. A signal transmitter is disposed on the remote controller, and the signal transmitter converts the electrical signal generated by the user operation into an infrared signal, and transmits the infrared signal to the outside. A signal receiver for receiving an infrared signal is disposed on the television, and the signal receiver further converts the received infrared signal into a signal signal, and the television performs the corresponding function according to the electrical signal.

Nowadays, people can watch TV at home with air conditioners. When people watch an exciting TV show, if an important call comes in, in order not to affect the quality of the call, people usually use the remote control to turn down the volume of the TV. There are two ways to adjust the volume. One is to adjust the volume to a small volume that meets the requirements by the volume increase and decrease buttons. However, this method has many steps, long time and inconvenience. The other method is to mute the button with a mute button, but if there are other people watching TV together at this time, the mute will affect other people, so the mute button is not convenient.

In view of this, it is necessary to provide an electronic device having a more convenient function of adjusting the volume.

It is also necessary to provide a volume control system for electronic devices that are more convenient to operate.

It is also necessary to provide a volume control method for an electronic device that is more convenient to operate.

2 is a flow chart of a volume control method of a preferred embodiment.

The following volume control systems and methods are applicable to a variety of electronic devices with audio output functions, such as televisions, DVDs, set-top boxes, CD players, and the like. The following is an example of the most common TV set in daily life.

As shown in FIG. 1, it is a functional module diagram of a television set according to a preferred embodiment. The television set 10 includes a sound reproducing unit 200 for playing back sounds and a volume for adjusting the volume of the sound reproducing unit 200. Volume control system 100. The volume control system 100 includes an input unit 101, a storage unit 103, a setting unit 105, a control unit 107, and a volume adjustment unit 109.

The input unit 101 is configured to generate a first input signal and a second input signal according to a user operation. The input unit 101 is a mute button or other newly added button on the television 10 or its remote controller. The user first operates the mute button or adds a button to generate the first pulse signal, that is, the first input signal, and the second operation. Then, a second pulse signal, that is, a second input signal, is generated.

The setting unit 105 generates a setting signal based on the operation of the user, and outputs the setting signal to the control unit 107 for setting a setting value and saving it to the storage unit 103. This setting is any value between the maximum and minimum values of the volume. The setting unit 105 includes a combination of a button device on the television 10 or its remote controller such as a menu button and a channel addition and subtraction, a volume addition and subtraction button. If the user can operate the menu button on the TV 10 or its remote control and use the channel addition and subtraction and volume up and down buttons to select the function of setting the “set value”, after selecting this function, the volume can be increased by volume plus or minus or channel plus or minus. Choose between a value and a minimum value that the user thinks the part affects the call and does not affect others. The volume value (such as "10") is taken as the set value, and then the menu button is pressed to save the set value to the storage unit 103.

The control unit 107 is configured to respond to the first input signal, store the current volume value of the sound playback unit 200 in the storage unit 103, and extract the set value in the storage unit 105, and output the set value to the volume adjustment unit 109.

The volume adjustment unit 109 is for adjusting the volume of the sound reproduction unit 200 to the set value in accordance with the set value output from the control unit 107.

If the current volume value of the sound playback unit 200 of the television set 10 is "30", if the volume up/down key is operated to adjust the volume of the sound playback unit 200 to a set value such as "10", it is necessary to operate the volume down key 20 times. Doing so many operations requires a lot of time and effort. According to the volume control system 100 according to the present embodiment, the volume of the sound reproducing unit 200 can be adjusted to "10" by simply operating the mute button or adding a button once.

The control unit 107 responds to the second input signal, extracts the stored current volume value, and outputs it to the volume adjustment unit 109. The volume adjustment unit 109 adjusts the volume of the sound playback unit 200 to the current volume value.

The volume control system 100 of the television set 10 can set a set value according to the needs of the user, and adjust the volume of the sound reproducing unit 200 of the television set 10 to the set value according to the user's operation on the input unit 101. The volume control system 100 of the television 10 according to the present embodiment is generated by operating the input unit 101, that is, the mute button or the new button, by repeating the operation of the volume up and down button to achieve the volume of the sound reproduction unit 200. The first input signal, and the first input signal is used to adjust the volume of the sound reproduction unit 200 to the set value, thereby adjusting the volume of the sound reproduction unit 200 to the set value by one operation, thereby avoiding the operation of the volume multiple times. The addition and subtraction keys adjust the volume of the sound reproduction unit 200 to a set value, saving time.

As shown in FIG. 2, it is a flowchart of a volume control method of a preferred embodiment. The volume control method is used to adjust the volume of the electronic device. The volume control method includes the following steps: Step 301: Generate a setting signal based on a user operation.

Step 303: Set a set value according to the setting signal, and save. This setting is limited to the maximum and minimum values of the volume. The user sets the size of the set value by operating a button of the electronic device such as a function meter of the television or its remote controller, and setting the value of the set value so that the set value does not affect the user's call and does not affect other users' viewing.

Step 305: Generate a first input signal based on a user's operation. A button on an electronic device such as a mute button on a television or its remote controller or a new button receives a user's operation to generate a pulse signal, that is, a first input signal.

Step 307: The first input signal is returned to adjust the volume of the electronic device to the set value. The first input signal should also store the current volume value of the electronic device.

Step 308: Generate a second input signal based on the user's operation. A button on the electronic device, such as a mute button on the television or its remote controller or a new button, receives the user's operation again to generate a second pulse signal, that is, a second input signal.

Step 309: The second input signal is returned to restore the volume of the electronic device to the current volume value.

The volume control method adjusts the volume of the electronic device to the set value by setting the set value and responding to the user's operation of the button of the electronic device, thereby avoiding repeatedly operating the volume plus or minus button on the electronic device. Quickly adjust the volume of the electronic device to save time.
