Description

Volume control device and method thereof

technical field

The invention relates to a volume control device and a method thereof, which can make a shortcut key area execute different function commands by using different operation modes.

Background technique

With the increasing popularity of computers, the functions that computers can perform are becoming more and more powerful, and the role played by computers has gradually extended from document processing in offices to audio-visual entertainment at home. Utilizing the powerful processing capability of the computer, multimedia files, such as MP3 or video files, can be played simultaneously while surfing the Internet or doing paperwork, making users accustomed to playing multimedia through computers.

When a user uses a computer, the keyboard is the most important command input unit for using the computer. Each key on the keyboard can correspond to a signal, so that the user can input commands to the computer by pressing or touching the keys on the keyboard. . However, in multimedia playback, since users may frequently select tracks or adjust volume, multiple shortcut keys are set in a functional area on many keyboards, and each shortcut key can correspond to a special function command. When the shortcut keys are touched or pressed, the keyboard can send a specific instruction to the computer, and the computer can perform corresponding multimedia functions according to the instruction, such as selection of tracks or adjustment of volume.

However, because the volume adjustment is to increase or decrease the volume in sequence, if the general shortcut key design is used, the user needs to repeatedly press a single button, so the user cannot control the volume of the audio through the keyboard. For easy volume control.

Detailed ways

The aforementioned purpose or features of the present invention will be described in detail according to the accompanying drawings. It should be noted that the following drawings and examples are only for illustration rather than limiting or narrowing the present invention.

The invention is a dual-mode keyboard, which can make a functional area execute different functional commands by using different operation modes.

Referring to FIG. 1 , it is a system architecture diagram of an embodiment of the present invention. A system of this embodiment includes a host 1 connected to a keyboard 2 and a speaker 3 respectively, the keyboard 2 is an input unit to provide the user with an input command, and the host 1 executes the command received from the keyboard 2, and can according to The received command adjusts the volume of the speaker 3 . The top of the keyboard 2 has a touch-type function area 20 and provides a row of multiple shortcut keys 21 to provide users with shortcut operations for specific functions such as multimedia playback.

The function area 20 has dual-mode operation settings. In the normal mode, each shortcut key 21 corresponds to a specific function command. When the user touches a shortcut key 21, the keyboard 2 can output the command corresponding to the shortcut key 21. , so that the host 1 can correspondingly execute the command, such as volume up, volume down, one song back, one song forward, play/pause, mute or stop and other functional commands, and then adjust the output of the speaker 3 volume.

According to an embodiment of the present invention, the left end of the shortcut keys 21 is the volume key V+, and the right end is the volume key V-, both of these two keys represent volume adjustment commands, wherein the volume key V+ represents the volume increase during the volume adjustment function, while the volume key V- represents the volume down function in volume adjustment. When the user touches the volume key V+ or V- for the first time, and touches the adjacent shortcut key for the second time within a predetermined time, the functional area 20 enters a volume control mode. Under the volume control mode, the function commands represented by individual shortcut keys 21 will suspend their functions, that is, when the user touches a shortcut key 21 in the volume control mode, the keyboard 2 will not press the shortcut key The command corresponding to 21 is output to the host 1 . In the volume control mode, when the user slides the touched button left or right, the keyboard 2 can output a volume control signal to the host 1 correspondingly according to the user's sliding position. And when the user does not touch any key in the functional area 20 for more than a preset time, or the touched key is not adjacent to the originally touched key, the functional area 20 will leave the volume control mode .

Referring to FIG. 2 , it is a flowchart of the steps of an embodiment of the present invention. As shown in the figure, in process 101, the keyboard 2 starts the touch detection function of the functional area 20; in process 102, the functional area 20 detects whether any key is touched, and if any key is touched, then Process 103, if no key is touched, then directly proceed to process 113; in process 103, the keyboard 2 sends an instruction to the host 1 according to the touched key; in process 104, the function area 20 detects the touched Whether the key is a volume key V+ or V-, if so, proceed to process 105, otherwise proceed to process 111; in process 105, the function area 20 further detects whether the key that the user touches next time is the same key as the last touch Volume key V+ or V-, if so, proceed to process 109, otherwise proceed to process 106; in process 106, the function area 20 detects whether the key touched in process 105 is adjacent to the key touched last time Press the button, if so, then proceed to process 107, otherwise proceed to process 112; in process 107, the keyboard 2 transmits an instruction that the key (volume key V+ or V-) touched in process 103 is released; in process 108, then The keyboard 2 executes the volume control mode; in process 109, the keyboard 2 detects whether the touched shortcut key is released, if so, proceeds to process 110, otherwise returns to process 105; in process 110, the keyboard 2 is sent to Process 103 is an instruction that the touched button (volume key V+ or V-) is released; in process 111, the keyboard 2 detects whether the touched shortcut key is released, if so, proceed to process 112, otherwise return to the process 111 ; at process 112 , the keyboard 2 transmits an instruction that the touched shortcut key is released; and at process 113 , end the process.

Wherein, in the process 108, the keyboard 2 executes a volume control mode, refer to FIG. 3 for a flow chart of the volume control mode. As shown in the figure, when in flow process 121, this keyboard 2 starts to execute this volume control mode; When in flow process 122, set a parameter X, wherein this parameter X is the volume change unit of every button interval, that is X=(maximum volume Vmax-minimum volume Vmin)/total number of shortcut keys; during process 123, the function area 20 detects the direction of the shortcut key touched by the user relative to the key touched last time, and if the user moves to the left, the Process 124, if the user moves to the right, proceed to process 128; at process 124, the keyboard 2 sends the command that the volume key V- is touched to the host 2; at process 125, the keyboard 2 immediately sends the volume key V- Released instructions are given to the host computer 2; at process 126, set parameter X=X-1; at process 127, check whether the parameter X is 0, if yes, proceed to process 132, otherwise return to process 124; during the process 128, the keyboard 2 transmits the command that the volume key V+ is touched to the host 2; during the process 129, the keyboard 2 promptly transmits the command that the volume key V+ is released to the host 2; during the process 130, then Set parameter X=X-1; During process 131, detect whether this parameter X is 0, if yes then carry out process 132, if otherwise return to process 128; And during process 132, this keyboard 2 leaves volume control model.

According to the above-mentioned embodiments of the present invention, a dual-mode button device can provide the user with a volume control mode to control the output volume of the speaker, and the user can increase or decrease the volume by sliding left and right, so that the user can use a simple operation method Control multimedia playback on your computer.

After describing the preferred embodiments of the present invention in detail, those skilled in the art can clearly understand that various changes and changes can be made without departing from the scope and spirit of the following patent applications, and the present invention is not limited to the specification Implementation of the examples given.
