Description
The present invention relates to a mobile device having a GPS information receiving function, and more particularly, to an audio system of a mobile device having a GPS information receiving function and a channel tuning method thereof.
In general, an audio device installed in a mobile device such as a vehicle receives a radio broadcast signal and outputs an audio signal based on the radio broadcast signal to the speaker. In order to select a desired radio broadcast channel, the user changes the reception frequency band of the tuner unit by using the frequency adjustment button.
The user may preset a number of radio broadcast channels which are frequently heard in shortcut keys (ie preset keys). As a result, the user can listen to the preset radio station by simply inputting the corresponding shortcut key.
In general, however, in order to use the preset function of a radio broadcast channel, the user directly searches for the radio broadcast channel one by one using the frequency control button, and then registers the searched broadcast channel to the preset key by operating a function key. Should be.
As described above, in the case of the conventional audio device, it is very cumbersome because the user has to directly manipulate the conventional audio device by hand in order to select a desired radio broadcasting channel. In addition, since the user cannot concentrate on driving due to the operation of the audio device for selecting a radio broadcast channel, it is difficult to ensure safe driving.
On the other hand, various devices using speech recognition have been recently developed. Generally, a speech recognition apparatus has a dictionary for recognizing speech and calculates a similarity degree between an input speech and words (for example, words) registered in the dictionary. If a word having the highest similarity can be extracted from a certain degree of similarity, the speech recognition apparatus recognizes that the input voice is the extracted word. Such voice recognition devices are used in devices of various technical fields.
The present invention can automatically display the names of a plurality of radio stations in the area where the mobile device is currently located when the mobile device is tuned while moving. An audio system of a mobile device and a channel tuning method thereof are provided. Another object of the present invention is to provide an audio system of a mobile device and a channel tuning method thereof, which can use a voice recognition function without a user's direct manipulation when operating a radio broadcasting function or inputting a desired station name.
According to an embodiment of the present invention, an audio system of a mobile device having a GPS information receiving function includes a GPS module and a storage unit in which a broadcast list table corresponding to a plurality of radio station names and frequency information for each region is prestored. An audio device for displaying a name of at least one radio station in an area corresponding to a current GPS position provided from the GPS module when an execution is input; and outputting a radio broadcast by setting a frequency of the input station name when a broadcasting station name is input. do.
The audio device includes an input unit for executing a radio function and selecting a broadcast station name, a tuner unit for tuning a radio channel, a storage unit for storing a broadcast list table including a plurality of regional station names and frequencies, an audio reproducing unit, and a video reproducing unit. Preferably includes a speaker, a display, and an audio control.
The input unit may include a microphone for inputting a user voice, and the audio device may further include a voice recognition unit configured to receive a user voice and output a voice signal, and the audio controller may include a region corresponding to a current GPS position in the broadcast list table. It is effective to search the names of a plurality of broadcasting stations broadcasted in and output the search results to the display unit.
The audio control unit receives information on the broadcast station name from the voice recognition unit, and transmits a broadcast selection signal including radio frequency information corresponding to the broadcast station name based on the broadcast list table stored in the storage unit. It is preferable to have a GPS information receiving function to output.
The audio processor converts an input audio signal input from the microphone into input audio data in response to a mode control signal input from the audio controller, outputs the input audio data to the voice recognition unit, and outputs broadcast audio data input from the audio controller. It is effective to convert the broadcast audio signal to the speaker.
The voice recognition unit operates in a radio reception mode under the control of the audio control unit, recognizes a user's voice based on the input audio data in the radio reception mode, and selects a corresponding broadcasting station name selected by the user based on the recognition result. It is preferable to output the information to the audio control unit.
According to another embodiment of the present invention, a channel tuning method for an audio system of a mobile device having a GPS information receiving function, comprising: pre-storing radio station names and frequency information corresponding to regions; Receiving current GPS location information from a GPS module when executing a radio function; Extracting and displaying at least one radio station name in a region corresponding to a current GPS position; Receiving a predetermined broadcast station name; And tuning the radio by setting a frequency of the input broadcast station name.
With this configuration, when the user of the mobile device selects a radio channel while moving, the user can automatically know the names of a plurality of radio stations in the current location, and when the desired station name is input, the radio is automatically tuned to a frequency corresponding to the input station name. Can be tuned into. In addition, when operating the radio broadcasting function or inputting the desired broadcasting station name, the voice recognition function may be used without direct manipulation of the user.
Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, in the following description, when there is a risk of unnecessarily obscuring the gist of the present invention, a detailed description of well-known functions and configurations will be omitted.
When the radio broadcasting function is operated in an audio system of a mobile device such as a vehicle, the present invention displays a list of names of a plurality of radio stations in the region where the vehicle is currently located, and inputs a desired station name based on the GPS position information. The radio is automatically tuned to a frequency corresponding to the input station name. In addition, when operating the radio broadcasting function or inputting the desired broadcasting station name, the radio broadcasting function is performed using the voice recognition function without the user's direct manipulation.
Hereinafter, with reference to the drawings will be described an embodiment of the present invention;
