In this specification, the singular also includes the plural unless specifically stated otherwise in the phrase. Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, a function key input device using an ultrasonic sensor according to an exemplary embodiment of the present invention will be described with reference to FIG. 1. 1 is a block diagram illustrating a function key input device using an ultrasonic sensor according to an exemplary embodiment of the present invention.

Referring to FIG. 1, a function key input device 10 using an ultrasonic sensor according to an exemplary embodiment of the present invention may include an ultrasonic sensor unit 101, a distance recognition unit 103, a motion recognition unit 105, and an audio control unit 107. ).

The ultrasonic sensor unit 101 generates ultrasonic waves by using an ultrasonic sensor and measures the return time reflected by an object or an input tool (for example, a human hand) within a predetermined distance.

The distance recognizing unit 103 calculates a distance to an object or an input tool by using the speed of the ultrasound according to the time when the ultrasonic wave is reflected and returns, and recognizes a distance to an object or an input tool close to the ultrasonic sensor.

The motion recognition unit 105 recognizes a movement of an object, an input means, or the like that is close to each ultrasonic sensor by using the plurality of ultrasonic sensors. That is, a plurality of ultrasonic sensors are used to recognize movement of an object, an input means, and the like that are close to each ultrasonic sensor.

The audio controller 107 inputs a predetermined function key according to the recognition result of any one of the distance recognizing unit 103 and the motion recognizing unit 105. In addition, the audio is controlled to perform a function corresponding to the input function key.

Here, the Function Keys are Power On / Off, Light On / Off, Button Input, Audio Play, Stop, Rewind, Fast Forward, Jump, Select Playlist, It means a predefined key to activate the file search and file selection functions.

On the other hand, the ultrasonic sensor unit 101 may be configured to include a plurality of ultrasonic sensors, to generate a plurality of ultrasonic waves to measure the time when each ultrasonic wave is reflected back to the object.

Meanwhile, the proximity distance between the ultrasonic sensor and the object or the input tool, the driving direction and the timing value of each ultrasonic sensor may be set according to the user's input.

On the other hand, the ultrasonic sensor may be configured to be mounted on the key input means of the car audio. On the other hand, the key input means of the car audio is made of thin plastics and fiber materials, etc. may be configured to easily pass the ultrasonic waves.

Meanwhile, the distance recognizing unit 103 may be configured to calculate a distance to the object or the input tool corresponding to the smallest time by calculating a time when the plurality of ultrasonic waves are reflected and returned by using the plurality of ultrasonic sensors. have.
