Description

Car audio device with touch sensor {THE CAR AUDIO SYSTEM USING TOUCH SENSOR}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a car audio device having a touch sensor. Specifically, a car sensor is provided in a conventional button switch to store voice data corresponding to the button switch, and the user does not directly see the car audio device. The present invention relates to a car audio device having a touch sensor that can find a desired button using the voice data output by contacting the touch sensor.

Conventional car audio devices are configured to receive user input using a button switch.

1 is a view showing the appearance of a car audio device having a conventional button switch.

The conventional car audio device 100 shown in FIG. 1 includes various button switches 110a to 110j, a display unit 120 for displaying image information, and a CD insertion / ejection tray 130. In addition, although not shown, a configuration for inserting or ejecting a cassette tape may be included.

The button switches 110a to 110j are configured to execute the operation of the car audio device by pressing a button, and generate different electrical signals corresponding to the respective operations by pressing the button switches 110a to 110j. . This is interpreted by a signal sensing device inside the car audio device, and provides an interface for performing a specific operation of the car audio device.

However, the button switches 110a to 110j have to be directly pressed by the user to see the button switches 110a to 110j, and thus may cause a safety hazard when operated during operation.

To compensate for this drawback, car audio devices with touch screens, such as capacitive touch switches, have been developed.

2 is a diagram illustrating an appearance of a car audio device having a capacitive touch switch.

As shown in FIG. 2, the car audio device 100 ′ is replaced with a capacitive touch switch 140a through 140j rather than the button switches 110a through 110j as a conventional car audio device including a button switch. have. In this case, the capacitive touch switches 140a to 140j may be external touch switches protruding out of the front panel, or may be internal touch switches mounted inside the front panel.

 When the touch screen touches the screen with a finger or a pen, the touch screen is configured to detect a portion in which a corresponding contact has occurred and to execute a command. The most representative method of operating the touch screen is a sensor line that responds to pressure applied to a screen surface. Is arranged in the form of X, Y axis and the (x, y) coordinates are read when the pressure is applied.

3 is a diagram illustrating a configuration of a touch screen using a conventional sensor line.

As shown in FIG. 3, the transparent touch screen panel 160 is attached to the display panel 150. In the transparent touch screen panel 160, the sensor lines 163a to 163e and 168a to 168d are arranged to form X and Y axes. The display panel 150 is a panel for implementing a display such as an LCD or an LED, for example, and the transparent touch screen panel 160 is attached to the display panel 150 to detect the user's touch. The sensor lines 163a to 163e and 168a may be used. To 168d).

The detection of the contact may be performed by measuring a change in resistance values of the X and Y axes when a user's finger or the like touches the transparent touch screen panel 120, and this method may be referred to as a "pressure sensitive".

However, a car audio device provided with such a touch screen also has a disadvantage in that an unwanted malfunction may be performed because a command is executed only by the user's contact unless the user directly looks and manipulates the touch screen.

The present invention has been made to solve this problem and includes a touch sensor in a conventional button switch, and stores the voice data corresponding to the button switch, the button switch as the voice data output by the user in contact with the touch sensor The present invention provides a car audio device having a touch sensor that can be operated in a desired operation without looking at the car audio device.

Car audio device having a touch sensor according to the present invention comprises a key input unit having a button for operating the car audio device; A touch sensor unit corresponding to the button provided on the key input unit to sense contact with a user; A voice data storage unit for storing voice data corresponding to the touch sensor unit; And a controller configured to detect the touch of the user, extract the voice data stored corresponding to the touch sensor unit, and control the car audio device.

In this case, the voice data may be voice guide information for the button of the key input unit corresponding to the touch sensor unit.

In addition, the car audio device having a touch sensor according to the present invention includes a voice converter for converting the voice data extracted from the control unit into an audio signal; A sound source reproducing unit which reads a sound source and converts it into an audio signal; It may include a speaker for outputting the audio signal converted from the sound source playback unit and the voice conversion unit at an audible frequency.

In addition, the touch sensor unit may be provided in the key input unit, and one or more buttons may be disposed on the button.

As described above, according to the present invention, a car audio device having a conventional button switch is provided with a touch sensor to store voice data corresponding to the button switch, and the voice data is output by contacting the touch sensor. Since the car audio device can be operated by knowing the function of a button, the user can safely operate the car audio device without directly looking at the car audio device.

Preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

4 is a block diagram illustrating a car audio device having a touch sensor according to the present invention.

As shown in FIG. 4, a car audio device having a touch sensor according to the present invention includes a key input unit 300, a voice data storage unit 310, a touch sensor unit 320, a controller 330, and a voice output unit ( 340, a sound source playback unit 350, a speaker 360, and a display unit 370.

The key input unit 300 selects a mode function and transmits a user's operation command to the controller 330.

The key input unit 300 may receive the control command of the user through the provided button and transmit the received control command to the controller 330, and the controller 330 may control the car audio device according to the control command.

The voice data storage unit 310 stores a voice data corresponding to a button provided in the key input unit 300. In this case, the voice data may be voice guide information on the button corresponding to the touch sensor unit 320.

The voice data storage unit 310 stores the voice data corresponding to the button, for example, "play" for a play button, "stop" for a stop button, "fast rewind" for a fast rewind button, and "pause" for a pause button. The operation button can be stored in the fast button as "fast forword". Voice data for selecting a mode function, for example, "tuner" for radio selection, "compact disc" for CD selection, and "tape" for cassette tape selection. "And so on.

In addition, the voice data storage unit 310 may record and store voice data corresponding to a manipulation command of the car audio device according to the user's preference.
