Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio calling apparatus suitable for use when a mobile communication device such as a mobile phone or a personal handyphone system (PHS) is required to notify an incoming call. It is a thing.

[0002]

2. Description of the Related Art Conventionally, notification of an incoming call in a mobile communication device such as a so-called mobile phone or PHS has been performed by generating a predetermined sound (for example, a beep sound). However, the generation of such sound causes annoyance to others in a place where many people gather, in a low noise environment such as a movie theater or a concert hall, and during a conference. On the contrary, in a noisy environment, it is difficult to hear the generated sound.

On the other hand, a method is proposed in which a vibrator having a vibrator function is wirelessly provided separately from the main body of the mobile communication device, vibration is generated by the vibrator when an incoming call is received, and the incoming call is notified by this vibration. It has been implemented. However, in such a method, some users may not always like such vibration, or may not like to carry the vibrator in close contact with the body.

On the other hand, the style of listening to music, such as an FM radio receiver, a portable cassette player with FM (headphone stereo) and a mini disk player with FM, etc., is always carried around, and the style of listening to music is established mainly in young people. It's starting. For a user having such a habit, only the user may not notice the notification sound of the mobile communication device or the like, which may disturb the surroundings. In addition, it is troublesome for a user with such a habit to carry the vibrator together with the main body of the mobile communication device, which is economically wasteful and not preferable.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to generate a sound when a call arrives in a conventional device in recognizing a ringing tone of a mobile communication device. For users who are unfavorable and have a habit of carrying electronic devices, wireless calling that eliminates the trouble and economic waste of carrying a vibrator together with the mobile communication device body and can recognize incoming calls while using electronic devices It is to provide a device.

[0006]

In order to solve such a problem, in a radio calling device of the present invention, a main body device such as a mobile communication device and a calling device such as an electronic device are separately formed, The main body device was provided with a transmitting means for oscillating and transmitting a specific frequency in synchronization with an incoming radio signal from the main body device, and the calling device was provided with at least a tuning means for tuning to the specific frequency. Then, when the notification from the main body device is requested, the calling device is activated by a radio signal from the main body device, and the notification from the main body device is transmitted to the calling device. This allows
The user can easily make a good call simply by carrying the main body device and the calling device.

The calling device is provided with a display means such as an LED or LCD, and the notice from the main body device is displayed on the display means and transmitted. Therefore, for example, the ringing tone of the main body device can be turned off, and the ringing tone does not disturb the surroundings.

Further, the calling device can be provided with or connected to a sounding means such as a speaker or a headphone, and the notification sound from the main body device is replaced (muted) with the sound of the calling device or the calling device. I mixed (mixed) with the sound of and output it. As a result, when a call is made from the main body device, it is possible to hear the ringing tone while normally listening to the voice of the calling device.

Further, since the radio signal includes a predetermined identification code, and the calling device determines the identification code to generate a ringing tone, a radio signal from another device is erroneously detected and malfunction occurs. The fear can be removed.
