1 is a block diagram showing the configuration of an audio component system equipped with a time signal apparatus according to the present invention.

Here, reference numeral 100 denotes signal selection means for selecting and outputting one audio signal from among the plurality of audio signals.

The signal selecting means 100 includes a tuner unit 10 for receiving and outputting AM and FM radio broadcast signals, an audio tape recording and reproducing unit 12 for reproducing an audio tape and outputting a reproduced audio signal, and a CD ( An optical disk reproducing unit 14 for reproducing an audio signal by reproducing an optical disk such as a compact disk, the tuner unit 10, an audio tape recording / reproducing unit 12, an optical disk reproducing unit 14, and an external device And a signal selector 16 which selects and outputs one of the external audio signals input to the input terminal AUX.

Reference numeral 18 is a mixer that mixes and outputs an audio signal output from the signal selecting means 100, a microphone audio signal input to the microphone terminal MIC, and a time signal audio signal.

The mixed audio signal of the audio signal, the microphone audio signal, and the time signal audio signal of the signal selecting means 100 mixed by the mixing unit 18 is output to the audio output terminal 22 through the amplifier 20, and then the L channel and the R signal. It is output to the speaker 24 and the headphone jack 28 of the channel.

Reference numeral 36 denotes an input unit for inputting an operation command according to a user's operation, and reference numeral 38 controls an operation of the signal selection unit 16 of the signal selection means 100 according to an operation command of the input unit 36. The control unit controls the generation of the time signal audio signal when the current time is counted and displayed on the display unit 34 and the set alarm time or the set time passes from the current time.

Reference numeral 32 denotes a time signal generator for generating a time signal audio signal under the control of the controller 38, and reference numeral 30 amplifies the time signal audio signal generated by the time signal generator 32 and inputs the signal to the mixing unit 18. It is an amplifier.

The time signal generator 32 is composed of a voice synthesis chip, and outputs, for example, a time signal audio signal that `` it has been promised '' or `` ○○ minute has elapsed from ○○ hour ○○ minute ''. It may be configured to be configured as an integrated circuit chip for melody or may be configured to output a predetermined melody.

Reference numeral 26 in the drawing of FIG. 1 denotes a headphone connected to the headphone jack 28.

In the audio component system having the time signal device of the present invention configured as described above, the tuner unit 10 of the signal selecting means 100 receives an AM or FM broadcast signal of a predetermined frequency and selects an audio signal while power is supplied. The audio tape recording and reproducing section 12 outputs the reproduction audio signal reproduced by reproducing the audio tape to the signal selecting section 16, and the optical disc reproducing section 14 reproduces the optical disc. The output audio signal is output to the signal selector 16, and the external audio signal input to the external input terminal AUX is input to the signal selector 16.

When the user inputs an operation command for selecting one audio signal by operating the input unit 36 in this state, the control unit 38 according to the input operation command, the signal selector 16 of the signal selection means 100. The audio signal of the tuner unit 10, the audio tape recording / reproducing unit 12, the optical disk reproducing unit 14, or the external input terminal AUX inputted by controlling the control unit is selected and output.

The audio signal selected and output by the signal selector 16 is input from the mixing unit 18 and output from the audio signal and the time signal generator 32 of the microphone input to the microphone terminal MIC and amplified by the amplifier 30. The signal is mixed with the time signal audio signal, amplified by the amplifier 20, and then output to the audio output terminal 22 and output to the speaker 24 and the headphone jack 28.

The controller 38 counts the current time and displays the counted current time on the display unit 34 so that the user can check the current time.

If the user operates the input unit 36 to set the alarm time or to output the time signal audio signal after a predetermined time elapses from the current time, the controller 38 reaches the set alarm time while counting the current time. Or, it is determined whether the predetermined time elapses, and when the determination result is the set alarm time or the predetermined time elapses, the controller 38 controls the time signal generator 32 to generate the time signal audio signal, The generated timed audio signal is input to the mixing unit 18 through the amplifier 30, mixed with the audio signal output by the signal selecting unit 16, and then output.

2 is a signal flow diagram illustrating the operation of the controller of FIG. 1 according to the time signal according to the present invention.

As shown in FIG. 2, when the user presses the time signal mode key and the general / specific mode key of the input unit 36, the controller 38 determines the setting of the time signal mode at step S100, and at step S102 a normal mode. Or determine whether a particular mode is set.

When the normal mode is set in step S102, the control unit 38 requests selection of the time interval between the display unit 34, and in step S104, the user sets the time interval, for example, through the input unit 36. For example, when time interval information such as 30 minutes or 60 minutes is selected, the control unit 38 stores the selected time interval information Td, and stores current time information in an internal timer (not shown).

In the next step S106, the time interval information Td input by the user is stored in the time register T, and in step S108, the value of the time register T is subtracted, i.e., the time register T. The time interval information Td stored in the subtraction is counted down.

In the next step S110, it is determined whether the value of the time register T which has been subtracted by counting is '0', and if the value of the time register T is not '0', the counting is continued. If the value is '0', in step S112, the controller 38 updates the current time information by adding the time interval information (Td) time to the current time information stored in the internal timer, and stores the result in the internal timer again. In addition, the time data for the elapsed time set by the time signal generator 32 is transmitted.

Then, the time signal generator 32 generates a predetermined time signal audio signal in step S114 according to the time data input from the controller 38. For example, the Td time has elapsed since the time of ○○ o'clock ○○. Generates an hourly audio signal, which is input to the mixing unit 18 through the amplifier 30, mixed with the audio signal output by the signal selector 16, and then through the amplifier 20. It is output to the speaker 24 and the headphones 26.

Therefore, the user may be notified of the time signal preset by the user in the state of listening to the predetermined music output from the audio component system as a time signal.

In this way, after generating the time signal audio signal, it is determined whether the time signal mode and the normal mode are released in the next step S116, and if the time signal mode and the normal mode have not been canceled, the process returns to step S104 to set the time. Repeat the generation of the time signal audio signal when elapsed.

Therefore, the user can be notified how much time has elapsed from the time set by the user at predetermined time intervals.

When a specific mode is set in step S102, the user requests input of specific time information in step S118, and stores information of a specific time input by the user and information of the current time.

In the next step (S120), the current time counted by the internal timer is checked to determine whether it is a specific time set by the user, and when the specific time is reached, the time signal for a specific time is sent to the time signal generator 32. do.

Then, in step S124, the time signal generator 32 generates a time signal audio signal, for example, `` it has been promised time '' or `` current time is ○○ hour ○○ minute '', and the generated time signal audio is generated. The signal is input to the mixing unit 18 through the amplifier 30, mixed with the audio signal output by the signal selecting unit 16, and then output to the speaker 24 and the headphone 26 through the amplifier 20.

Therefore, the user can easily know that the predetermined time is reached while enjoying the predetermined music output from the audio component system.

As described in detail above, the time signal method and the time signal device according to the present invention not only notify the user when a specific time set by the user, but also detects the elapsed time from the current time and notifies the elapsed time so that the user outputs the audio component system. Even while enjoying the predetermined music, it is possible to know the specific time and the passage of time accurately.
