Abstract

PURPOSE:To record a radio audio signal and to inform it to the user by using a signal from a radio receiver as a trigger signal when a radio signal is muted during talking when a telephone set mounted on an automobile is in use. CONSTITUTION:A signal from a radio receiver 3 is muted during talking and when a signal is sent from the radio receiver 3 for that time, then it is informed to an on-vehicle stationary section 2 by an inter-R-C IF 4 (4-1). The on-vehicle stationary section 2 controls the radio receiver 3 by using inter-R-C IF 4 (4-3, 4-4) and the recording is informed to the user by a sound, a liquid crystal display device (LCD) and vibration or the like.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio voice recording method during radio mute (silence) when an automobile telephone is used on a vehicle.

[0002]

2. Description of the Related Art Conventionally, when a telephone call is made while using a car telephone, the voice is automatically muted when the radio is turned on.

[0003]

However, there is a problem that information cannot be obtained from the radio because the radio mute state is set during the above-mentioned conventional telephone communication by the mobile telephone.

The present invention solves such a conventional problem, and even in a radio mute state, information such as temporary news is automatically recorded by a signal from the radio and reproduced later, so that the user can reproduce the information. It is an object of the present invention to provide a radio voice recording method having an excellent function that can notify the user.

[0005]

In order to achieve the above object, the present invention is such that an on-vehicle fixed part controls a radio and starts and stops a radio voice recording by a signal from the radio. Further, the radio is provided with an external terminal capable of notifying information such as the presence or absence of temporary news.

[0006]

Therefore, according to the present invention, when the radio outputs a signal to the external terminal, the on-vehicle fixed part starts or stops recording via the interface between the radio and the on-vehicle fixed part (hereinafter referred to as R-C IF). You can know the timing. If the vehicle-mounted fixed part is in the telephone call state at this time,
Recording of radio sound can be started or stopped by the signal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a schematic system configuration of an embodiment of the present invention when the vehicle telephone is mounted on a vehicle, and FIG. 2 shows a block configuration of the embodiment when the vehicle telephone is mounted on a vehicle. It is a thing. 1 and 2,
1 is a car phone, 2 is a vehicle fixed part, 3 is a radio, 4 is an interface between the radio 3 and the vehicle fixed part 2 (IF between R and C), temporary news start / stop information 4-1, radio audio 4 There are -2, mute control 4-3 and switch control 4-4. Reference numeral 5 denotes an interface between the car telephone 1 and the in-vehicle fixed unit 2, which has a switch control 5-1 and an audio 5-2. The in-vehicle fixed part 2 has a recording unit 20, a switch 21 and a switch 22, and the radio 3 has a mute means 30 and a switch 31.

Next, the operation of the above embodiment will be described.
If the vehicle-mounted fixed unit 2 receives a start signal from the temporary news start / stop information 4-1 of the radio 3 during a call on the car phone 1, the vehicle-mounted fixed unit 2 sends a switch control 4-4 to the radio 3 and the switch 31. Is controlled to switch the radio audio 4-2 to the in-vehicle fixed part 2 side, and the mute means 30 is unmuted by the mute control 4-3. Further, the switch 21 is controlled to start recording the radio sound in the recording unit 20. Next, if a stop signal is received, the switch 21 is controlled to disconnect the recording unit 20 from the radio audio 4-2 to stop recording, and the mute control 30 is used to control the mute means 30 to mute. Switch the radio audio 4-2 to the speaker side with the switch 31. In addition, the user is notified of the recording by sound, liquid crystal display (LCD), vibration or the like. As a result, the user can later control the switch 22 of the in-vehicle fixed unit 2 from the mobile phone 1 to listen to the temporary news that could not be heard because the user was busy.

[0009]

As is apparent from the above-described embodiment, the present invention allows a user to record a radio sound by using a signal from the radio as a trigger even when a mobile phone is in a call, so that the user can make a temporary recording later. It has an effect of being able to hear news and the like.
