1 is a block diagram of a system for performing a car audio playback method using a dial according to the present invention. Referring to FIG. 1, an audio system according to the present invention selects a sound source source from a deck unit 10 for providing a sound source source through a medium of radio, tape, CD, and the deck unit 10 according to a user input. A control unit 20 for generating a control signal for reproduction, a function control unit 30 for inputting a user's selection signal for selecting an operation of the deck unit 10 to the control unit 20, and the function control A display unit which displays a playback unit 40 for receiving a control signal of the control unit 20 with respect to the sound source selected by the unit 30 to reproduce the sound source, and an operation display screen for displaying the current operation state of the deck unit 10 ( 50).

The deck unit 10 includes a tuner unit (TUNER) 11 for playing a radio, a tape deck unit (TAPE DECK) 12 for playing a tape, a CDP unit 13 for playing a CD, It may be composed of a CDC unit 14 for selectively playing a plurality of CDs.

The controller 20 selects and plays one sound source from the radio, tape, and CD on the deck unit 10 according to the input signal of the function controller 30. The playback method performed by the control unit 20 will be described later.

The function adjusting unit 30 may employ a control dial to generate a click signal according to the rotation direction, or employ a control button to generate click signals in different directions according to the pressing direction. In the following embodiment will be described by employing the control dial.

The function control unit 30 is a volume or each function mode performed in the conventional car audio, for example, bass control (BASS)-> treble control (REBLE)-> front and rear volume control (FADER)-> left and right volume control It is provided separately from the volume control dial configured to perform functions such as (BALANCE)-> VOLUME-> BASS.

This separately provided is to perform the functions as described above, and to control each operation mode by inputting the user's input signal in the radio, tape, CD operation mode by a simple left and right rotation.

The playback unit 40 performs amplification and filtering functions to reproduce the sound source selected by the deck unit 10 through the speaker according to the user's input signal, and adjusts the volume, front, rear, left and right, and sound quality according to the user's operation signal. It may also be configured as an audio processor that performs a function such as.

The display unit 50 may display which sound source is selected in the deck unit 10 to operate in which operation mode, the broadcast frequency of the radio being played, the track status of the CD being played, and the like.

The operation of the car audio system according to the present invention configured as described above will be described. Press the control dial 30 once to perform the following functions.

For example, BASS-> TREBLE-> FADER-> BALANCE-> VOLUME-> BASS can do. At this time, by pressing the control dial 30 once, it is in a control state capable of adjusting each mode for, for example, 5 seconds for a predetermined time. At this time, if no operation is performed within 5 seconds, it is returned to the original mode.

In this case, the conventional car audio is generally used as a volume control button in each mode step to perform high, low, front and rear volume control, in the car audio according to the present invention so that the adjustment dial can be adjusted to the left and right in the above adjustment state. It is designed.

That is, in the conventional case, the present invention secures the driver's safety by allowing the user to easily adjust using the same control dial as compared to performing each state control using the volume button or another button in each state mode after pressing the audio button. Make it possible.

In addition to performing the audio adjustment mode each time the control dial is pressed once, the following operation is performed.

2 is a general flowchart of a car audio playback method using a control dial according to the present invention. Referring to FIG. 2, a car audio playback method using a control dial will be described.

First, it is determined whether there is a push input for the control dial (S1). If there is a push input, the mode-specific adjustment function is performed to proceed to the normal audio control mode (S2). On the other hand, if there is no push input, it is determined whether there is a rotation input for the control dial (S3). If there is a rotation input, the current operation mode is read (S4). The current operation mode may be a radio operation mode, a tape playback mode, or a CDP / CDC playback mode. Then, read the direction of rotation of the control dial (S5). For example, there may be a clockwise or counterclockwise direction. After obtaining information on the rotation direction, the number of rotation clicks of the control dial is counted (S6). In this way, when information on the current operation mode, the rotation direction, and the number of rotation clicks is obtained, a function according to each operation mode is performed based on the information.

To this end, first, it is determined whether the RADIO operation mode (S7). In the case of the RADIO operation mode, it performs the RADIO control mode function, and if it is not the RADIO operation mode, it is determined whether the TAPE operation mode (S8). In the TAPE operation mode, the TAPE control mode function is performed, and in the non-TAPE operation mode, it is determined whether the operation is the CDP / CDC operation mode (S9). In the CDP / CDC operation mode, the CDP / CDC control function is performed.

As such, when the current operation mode is RADIO / TAPE / CDP / CD CHANGER, various various operations are performed according to the left / right rotation input of the control dial.

That is, in the RADIO control mode, the address of the memory of the pre-stored frequency is changed according to the left and right inputs of the control dial to tune the frequency of the corresponding reproducing memory address so that the broadcast of the tuned frequency is reproduced.

In the TAPE adjustment mode, the left and right inputs of the control dial move forward and backward to the currently playing song, and the selected song is selected to play.

In the CDP / CDC control mode, the left and right inputs of the control dials move forward and backward to the track of the track currently being played to select the track corresponding to the track and play the selected track.

Then, let's take a closer look at how the current operation mode operates according to the left / right rotation input of the control dial when the RADIO / TAPE / CDP / CD CHANGER is respectively.

First, let's look at the operation of the left and right input of the control dial in the RADIO control mode.

If the control dial is changed left and right during operation in the radio state, the memorized broadcast can be sequentially tuned accordingly. For example, if you turn it clockwise, you will hear the broadcast stored in memory. Table 1 shows, for example, a case in which each radio frequency is memorized in each radio reproduction memory address, which is a case of a reproduction memory capable of storing six broadcast channels.

M1 M2 M3 M4 M5 M6 89.1 91.9 93.6 95.1 95.9 97.3

As can be seen in Table 1, each memory stores a radio channel of the specified frequency. Therefore, when the currently tuned frequency is 93.6 MHz, turning the control dial counterclockwise makes the tuning for the frequency stored in M2 and the frequency stored in M1 according to the number of clicks on the control dial. On the other hand, when the control dial is turned to the right, the frequency stored in M4 in the case of a single click and the frequency stored in M5 in the case of a double click can be tuned.

3 is a flowchart illustrating an operation in a radio mode of a car audio playback method using a control dial according to the present invention. Referring to FIG. 3, a car audio playback method using a control dial performed in a radio mode will be described in more detail.

First, when the current operation mode is operating in the radio mode, it is determined whether or not the current playback memory address is designated (S11). If it is determined that the current playback memory address is designated, the current playback memory address is read (S12). For example, in Table 1, if a broadcast of a frequency of 93.6 MHz is being reproduced, it can be seen that a third reproducing memory address is designated. On the other hand, if a broadcast of a frequency not included in the reproduction memory address is being reproduced, the first reproduction memory address is designated as the current reproduction memory address (S13). For example, if a 104.5 MHz broadcast, which is not shown in Table 1, is being played, the first playback memory address (89.1 MHz) is designated as the current playback memory address.

If the current playback memory address is designated as described above, a subsequent procedure according to the rotation direction is performed. That is, it is determined whether the rotation direction is the right side (S14). As a result of the determination, when the rotation direction of the control dial is on the right side, the frequency of the reproduction memory address which has moved forward by the number of rotation clicks from the current reproduction memory address is tuned (S15). For example, in Table 1, when the broadcast of the frequency of 93.6 MHz in the third reproducing memory address is being reproduced, if the number of rotation clicks is 3, the frequency of 97.3 MHz in the sixth reproducing address is tuned.

On the other hand, if the rotation direction of the control dial is not the right but the left side, the frequency of the playback memory address shifted backward by the number of rotation clicks from the current playback memory address is tuned (S16). For example, in Table 1, when the broadcast of the frequency of 93.6 MHz in the third reproducing memory address is being reproduced, if the number of rotation clicks is 2, the frequency of 89.1 MHz in the first reproducing address is tuned.

When the frequency of the corresponding playback memory address is tuned according to the rotation of the control dial, the control signal is transmitted to the TUNER section 11 and the playback section 40 so that the broadcast of the tuned frequency is reproduced.

On the other hand, let us explain the operation in the tape playback mode of the car audio playback method using the control dial according to the present invention.

During tape play, turn the control dial clockwise one click to perform the tape AMS-FF function (automatic selection), which stops at the beginning of the next song you are currently listening to and plays it. On the other hand, if the control dial is turned one click counterclockwise during tape play, the tape AMS-REW function is performed to stop and play at the beginning of the current song.

At this time, the same operation is performed even if the user rotates several clicks instead of one click in the clockwise direction (or counterclockwise direction) .If the clock is rotated again while the tape AMS function is being executed, the AMS operation is canceled and the tape is moved from the current position. Is played.

In addition, if you turn it counterclockwise while the tape AMS function is running, the AMS operation is executed in reverse.

Operating status Turn counterclockwise Turn clockwise PLAY Perform AMS-REW Perform AMS-FF AMS-REW Played after stopping the current position Perform AMS-FF AMS-FF is running Perform AMS-REW Played after stopping the current position Car audio display Display A-RE display A-FF display

In Table 2, AMS-FF is auto-selection fast forward and AMS-REW represents auto-selection fast forward.

4 is a flowchart illustrating the operation in the tape playback mode of the car audio playback method using the control dial according to the present invention. Referring to FIG. 4, a car audio playback method using a control dial performed in a tape playback mode will be described in more detail.

First, when the current operation mode is operating in the tape playback mode, the subsequent procedure according to the rotation direction is performed. That is, it is determined whether the rotation direction is the right side (S21). As a result of determination, when the direction of rotation of the control dial is on the right, AMS-FF is performed to move to the beginning of the next song after the current song (S22).

On the other hand, if the rotation direction of the control dial is not the right side but the left side, the AMS-REW is performed to move to the beginning of the immediately previous song of the current playback song (S23).

When moving to the corresponding portion of the tape in accordance with the rotation of the control dial in this way, by transmitting a control signal to the TAPE DECK unit 12 and the reproducing unit 40 to play the tape from the moving portion.

On the other hand, let us explain the operation in the playback mode of the CDP / CDC of the car audio playback method using the control dial according to the present invention.

CDP and CDC differ only in the number of discs inserted (DISK), but once a CD is selected for playback, one CD is played.

While playing the CDP / CDC, turn the control dial clockwise to perform the TRACK UP function to play at the beginning of the next track you are currently listening to. On the other hand, if the control dial is turned counterclockwise during CDP / CDC performance, the track down function is performed to stop and play at the beginning of the current song. At this time, when rotating in the counterclockwise direction, if it is 1 click, it can be moved to the beginning of the current song, and if it is 2 clicks, it can be moved to the beginning of the previous song.

In addition, when a variable click is made several times instead of one click, the selected song is played in proportion to the number of clicks. At this time, if the CD song is the end song, the first track of the current CD is played and the selected song is played in proportion to the number of clicks.

5 is a flowchart illustrating the operation in the CDP / CDC mode of the car audio playback method using the control dial according to the present invention. Referring to Figure 5 will be described in more detail car audio playback method using a control dial performed in the CDP / CDC mode.

First, when the current operation mode is operating in the CDP / CDC mode, the track currently being played is read (S31). When information on the track currently being reproduced is obtained, a subsequent procedure according to the rotation direction of the control dial is performed. That is, it is determined whether the rotation direction is the right side (S32). As a result of determination, when the direction of rotation of the control dial is on the right side, track up is performed to move from the track currently being played to the beginning of the song on the next track by the number of rotation clicks (S33). For example, if the number of rotation clicks is 3, it moves from the track of the track currently being played to the beginning of the track of the third track.

On the other hand, if the direction of rotation of the control dial is not the right but the left side, the track is down to move from the track currently being played to the beginning of the song in all tracks by the number of rotation clicks -1 (S34). For example, if the number of rotation clicks is 3, it moves from the track of the currently playing track to the beginning of the track on the second track. This is because in the case of the left rotation, the first first click goes to the beginning of the track of the track currently being played, and the next click moves to the previous track.

When moving to the corresponding part of the track as the control dial is rotated in this way, control signals are transmitted to the CDP unit / CDC unit 13 and 14 and the play unit 40 so that the CD is played from the moved portion.

The control method using the control dial according to each operation mode as described above can be summarized as the following table.
