Next, the operation of the karaoke system of the embodiment will be described. FIG. 2 is a flowchart showing the operation of the karaoke system of the embodiment. When the power is turned on in step 1, the karaoke system is initialized (step 3). In this initialization, a menu screen 40 shown in FIG. Here, the navigation mode and TV mode switches 41 and 42 are displayed,
These modes can be selected. The mode at the time of initialization can be determined in advance by the initial setting.

In step 5, it is determined whether or not the mobile phone 7 is connected to the communication section 3. If the mobile phone 7 is not connected to the communication unit 3 (step 5;
N), proceed to step 11; In this case, the telephone mode and the communication karaoke mode are prohibited. When the mobile phone 7 is connected to the communication unit 3 (Step 5; Y), the telephone mode is set, and the subroutine shown in FIG. 5 is executed (Step 7). The subroutine of FIG. 5 will be described later.

In step 9, the display of the communication karaoke mode is set, and the communication karaoke mode switch 43 appears on the menu screen 40 as shown in FIG. Thereby, the communication karaoke mode can be selected.

When the navigation mode is selected on the touch panel type menu screen 40 (step 11; Y), the navigation mode is set (step 13). In this navigation mode, the extension device 5
The car navigation device 51 connected to the karaoke system main unit 1 via is activated. Since the operation of the car navigation device 51 is well known, a detailed description is omitted. However, the map data and the selected route are displayed on the display 15.
And the speaker 33 is used for voice navigation.

When the TV mode is selected on the menu screen 40 (step 15; Y), the TV mode is set (step 17). In this TV mode, the TV receiver 53 connected to the karaoke system main unit 1 via the extension device 5 is activated. The TV image signal received by the TV receiver 53 is sent to the display via the extension device 5, the external extension unit 13, and the screen control / output unit 19. The TV audio signal is sent to the speaker 33 via the audio input / output unit 31 via a path (not shown).

When the communication karaoke mode is selected on the menu screen 40 (step 19; Y), the communication karaoke mode is selected (step 21). In the communication karaoke mode, the karaoke system body 1 is connected to the central unit of the communication karaoke system via the communication unit 3 and the mobile phone 7. And the data is exchanged between the two,
Karaoke is performed according to the user's request, and the background image and the lyrics telop are displayed on the display 15. Various types of communication karaoke systems have been proposed (for example, see JP-A-6-102888), but are not particularly limited as long as they can execute communication karaoke using a mobile phone.

The main routine shown in FIG. 2 ends when the power is turned off. Each step is executed by the main control unit 11 controlling each element shown in FIG. The role of the main controller 11 is the same in the subroutines shown in FIGS. 5, 6, 8 and 9.

Next, returning to step 7 in FIG. 2, the telephone mode will be described. The telephone mode is performed by a subroutine shown in FIG. This subroutine includes a navigation mode (step 13) and a TV mode (step 1).
7) Or executed in parallel with the communication karaoke mode (step 21). Therefore, when the power of the karaoke system main body 1 is turned off, this subroutine also ends.

When the telephone mode starts, first, at step 71, it is determined whether or not there is an incoming call to the portable telephone 7. If there is no incoming call (step 71; N), the process proceeds to step 75, and if there is an incoming call (step 7).
1; Y), the subroutine of the incoming call mode shown in FIG. 6 is executed (step 73).

When the incoming call mode starts, the audio output is first muted as shown in FIG. 6 (step 731). For example, during a karaoke performance, the audio signal from the karaoke performance unit 27 to the audio control unit 29 is cut.

Then, in step 733, an incoming call is displayed. FIG. 7 shows an example of an incoming call display in the karaoke mode. In this embodiment, the screen 45 of the display 15 is
The incoming call display 47 flashes above the lyrics telop 46 in. The karaoke performance is muted, but the background image 48 and the lyrics telop 46 are executed on the screen 45.

Next, at step 734, it is determined whether or not the answering machine mode is set. Note that the answering machine mode is set by the user. If the answering machine mode is set (step 734; Y), the answering machine mode is executed in step 735. Thereby, when the call is not answered during the predetermined number of incoming calls, the answering guidance saved in the ROM (not shown) of the main control unit 11 is transmitted to the other party. And
The message of the other party can be recorded in the storage device 25.

If the answering machine mode is not set (step 734; N), the process proceeds to step 736, where it is determined whether or not the running mode is set. The running mode is set by the user.

If the running mode is not set (step 736; N), the flow advances to step 738 to execute the subroutine shown in FIG. 8 for hands-free communication. Here, the hands-free call is started by touching the incoming call display 47 on the screen 45. The main control unit 11 receives the audio signal sent to the mobile phone 7 via the communication unit 3, sends this to the audio control unit 29, decodes the signal, and outputs the signal to the speaker 33 via the audio input / output unit 31. Output more. On the other hand, the voice input from the microphone 35 is input to the voice control unit 29 via the voice input / output unit 31, encoded here, and a voice signal is transmitted from the main control unit 11 to the mobile phone 7 via the communication unit 3. Output. This signal is wirelessly communicated from the mobile phone 7 to the base station.

In FIG. 8, when the call mode starts,
The microphone 35 and the speaker are turned on (step 738)
1, step 7383). Next, the howling prevention function provided in the voice control unit 29 is activated (step 7).
385). This enables hands-free communication. Then, the data in the storage device 25 is cleared, and the contents during the call can be stored in the storage device 25 (step 7387). The recording mode during a call is set by the user.

During a call, the incoming call display 47 is replaced by a display indicating "calling". Then, by touching the "during call" display, the call is terminated.

On the other hand, if the running mode is set (step 736; Y), the running mode subroutine shown in FIG. 9 is executed.

In the running mode, as shown in FIG. 9, first, in step 7371, it is determined whether or not the vehicle speed ≧ 0.1 km has continued for 3 minutes or more in order to check whether or not the vehicle is running. to decide.

If the vehicle is running (step 7)
371; Y), and proceed to step 7372. In this step, the call to the mobile phone 7 is set to an on-hook state, and a voice guide is output in step 7373. This voice guide is provided by an R (not shown) of the main control unit 11.
For example, a voice guide that is stored in the OM and is transmitted to the other party, for example, "I am currently driving in a car and cannot answer the call.

Then, in step 7374, the voice of the other party can be input to the storage device 25. The voice of the other party recorded here is automatically reproduced after the termination of the incoming call mode.

On the other hand, when the vehicle is stopped (step 7371; N), the process jumps to the talking mode (step 738).

The subroutine shown in FIGS. 6, 8 and 9 ends when the call ends or the answering machine ends.

Returning to the flow of FIG. 5, when the above-described incoming call mode ends, it is determined whether or not a call has been made by the user (step 75). The transmission is performed by operating a predetermined portion of the screen 45 of the display 15. If there is an outgoing call (step 75; Y), the process proceeds to step 77, where the outgoing call mode is executed.

In this transmission mode, first, the audio output is muted, as in step 731 in FIG. 6, and then the process jumps to the call mode in step 738 to enable a call. During a call, the screen 4 of the display 15
5 is displayed as "calling", and touching the "calling" display ends the call.

The present invention is not limited to the description of the above-described embodiments and examples, but includes various modifications that can be made by those skilled in the art without departing from the scope of the claims.
