CAR AUDIO DEVICE CAPABLE OF RECORDING RADIO BROADCASTING SOUND}

1 is a block diagram of a car audio device according to a preferred embodiment of the present invention.

2 is an operation flowchart of a car audio device according to a preferred embodiment of the present invention.

The present invention relates to a car audio device, and more particularly, to a car audio device for storing broadcast contents received through a car audio device.

The car audio device is installed in a center passenger inside the vehicle, and provides a function of listening to AM / FM broadcasting, or playing back audio cassette tape or playback of a compact disc (CD).

However, the conventional car audio device is not equipped with a function of recording music or the like reproduced through AM / FM broadcasting on a cassette deck or other storage medium, or recording a conversation content by a driver, etc. in a vehicle.

In order to solve the above-described problem, the present invention provides a function of selectively recording audio signals received from an AM / FM tuner of a car audio device and a driver's dialogue contents in a cassette deck or a portable storage medium such as a flash memory card. In addition, an object of the present invention is to provide a car audio device in which a driver can use a recording function by simpler key manipulation.

In order to achieve the above object, according to an aspect of the present invention, an AM / FM tuner for receiving a radio broadcast, a tape deck for playing and recording audio tape, and a memory card for inserting a memory card to store information. There is provided a car audio device including a slot, a key input provided with a record button, a microphone attached to the front panel of the car audio device, and an MPU. When the record button provided in the key input unit is clicked, the MPU selectively designates one of the tape deck and the memory card slot as a recording medium according to whether or not recording is possible on the audio tape inserted in the tape deck. The radio broadcast signal is stored in the designated recording medium when the / FM tuner is in operation, and the audio signal received from the microphone is stored in the selected recording medium when the AM / FM tuner is not in operation.

In this case, the storage unit may further include a display unit for displaying a storage completion message when the storage operation of the MPU is completed, wherein the MPU message indicating the storage capacity exceeded in the storage completion message when the storage capacity of the designated recording medium is exceeded. Can be added to the display unit.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.                     

1 shows a configuration of a car audio device according to a preferred embodiment of the present invention.

As shown in FIG. 1, a car audio device according to a preferred embodiment of the present invention includes a tape tech 110 for playing / recording an audio tape, a CDP deck 120 for playing / recording a CD, and radio broadcasting. An AM / FM tuner 130 for receiving a signal, a key input unit 140 including a plurality of buttons for inputting an operation command by a user, a display unit 150 for displaying an operation state of a car audio device, and a memory; Memory card slot 160 for recording data by inserting a card, a speaker 170 for outputting a sound signal, and a microphone 180 installed at a front panel of a car audio device and converting a user's voice or the like into an electrical signal. ) And a microprocessing unit (MPU, hereinafter referred to as " MPU ") 190 for controlling each component described above. In addition, description of well-known component is abbreviate | omitted in this invention.

The key input unit 140 according to the present invention includes a recording button. When the user presses the recording button, the recording function is performed, and the recording medium may be automatically selected. Details thereof will be described with reference to FIG. 2.

2 is a flowchart illustrating operations of a car audio device according to the present invention.

First, when the user selects the record button provided in the key input unit 140 (S100), the MPU 190 is a medium that is being played from the tape tech 110, the CDP deck 120, and the AM / FM tuner 130. It is determined whether there exists (S110). If it is determined in step S110 that there is a medium being played, it is then determined whether the tape deck 110 is being played (S120).

If the tape deck 110 is being played back, since recording to audio tape cannot be performed, a memory card inserted in the above-described memory card slot 160 is selected as a storage medium from the tape deck 110 being played back. The sound signal of the digital form is stored (S130). If it is determined in step S120 that the medium being played is not tape, it is determined whether recording can be performed on the audio tape inserted in the tape deck (S150). For example, if the tape is not inserted into the tape deck or the tape cannot be recorded even if it is inserted, the tape cannot be recorded. Therefore, the process proceeds to the step S130 described above, whereby the audio signal from the medium currently being played is output from the memory card. Store in If it is possible to record on the audio tape inserted in the tape deck in step S150, the audio signal from the media currently being played is stored in the audio tape (S160).

Referring back to step S110, if there is no medium being played, the user wants to record a signal input from the microphone, and thus the MPU selects a recording function using the signal input from the microphone 180 as a source signal. (S140).

When the microphone signal is selected as the input signal in the above-described step (S140), the process proceeds to the above-described step (S150). That is, in step S150, for example, if the audio tape is not inserted into the tape deck or the tape is impossible to record even if it is inserted, the tape cannot be recorded. Therefore, the process proceeds to the step S130 described above and is currently playing. The audio signal from the medium is stored in the memory card. If it is possible to record to the audio tape inserted into the tape deck in step S150, the audio signal from the media currently being played is stored in the audio tape (S160).

In step S130 or step S160, when the storage operation is completed, a message indicating the completion of storage is output on the display unit 150 of the car audio device to allow the user to recognize that the storage is completed. On the other hand, when the user presses the above-described recording button again, when there is a mute signal for a predetermined time or more in the audio signal (including the AM / FM broadcast signal) from the playback medium, or on the tape / memory card used as the storage medium. If the above storage cannot be performed, the storing can be completed, and the message corresponding to each case described above can be included in the storing completion message. That is, in the present invention, the storage completion can be programmed in advance so that the storage is automatically completed without a user's storage completion instruction.

Although the preferred embodiment according to the present invention has been described above, this is merely exemplary and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the protection scope of the present invention should be defined by the following claims.

As described above, according to the present invention, the audio signal received from the AM / FM tuner of the car audio device and the conversation of the driver can be selectively recorded on the cassette deck or the portable storage medium, and the user does not specify the storage medium separately. If not, the storage medium is automatically selected, which has the advantage of improving user convenience.
