JPH0946398A - Incoming telephone notifying device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent the loss of the timing for obtaining information, although a user is at home, because of the adverse effect due to incoming sound and the incoming sound out of his hearing range by receiving ac voltage transmitted as a call signal from a telephoneline and emitting an incoming notifying radio wave. SOLUTION: An oscillation part 7 is composed of an IC 22 for transmission and a voltage regulator 23 for voltage stabilization, generates the voltage of a prescribed frequency and supplies the voltage to the signal oscillation part 11 in the next stage. The signal transmission part 11 receives the voltage of a prescribed frequency from the oscillation part 7 and emits an incoming notifying radio wave from an antenna 9 via an LC resonance circuit 27. This device has a modulation circuit part 29 modulating the frequency of a carrier wave according to the signal voltage from the oscillation part 7 when an FM pocket radio is used as a reception means. Thus, while a bady is sleeping, etc., a user wears a reception means and sets the device to the small in the range in which the only user hears, and conversely, when the user goes out to dry washed clothes, etc., or uses a cleaner, he set the device to the large volume enough to hear notification sound. As a result, the using forms according to purpose can be taken.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary device for a telephone, which emits a radio wave for receiving an incoming call without sounding the ringing tone of the telephone and various receptions including an FM radio provided separately. The present invention relates to an incoming call notification device for issuing an incoming call alert instead of a ringing tone by means.

[0002]

2. Description of the Related Art Needless to say, the present telephone set has received a call by connecting an individual telephone set to a terminal telephone line and ringing a ring tone with an AC voltage as an incoming signal. To inform the user.

[0003]

However, sometimes the ringing tone of the telephone itself becomes annoying noise,
There may be a problem that the incoming call cannot be recognized even though the ring tone sounds. First of all,
It can occur while the baby is sleeping. In other words, young married couples who have just married often have a 0-year-old baby, and considering the housing situation in Japan, it is difficult for younger people to own a detached house, and in general In most cases, apartments and heights with a small area are used as housing. Therefore, the baby's sleeping place and the telephone installation place are often very close to each other, and the ringing tone of the telephone often causes the sleeping infant to wake up, which adversely affects the infant's life rhythm. . Next, in the case of, regardless of the size of the living area, it may occur during housework of a housewife, for example. That is, when the laundry is hung up in the outdoor clothes-drying place, or when the upper floor or the lower floor of the telephone installation place is vacuumed, the ringing tone of the telephone often cannot be heard. . On the other hand, although the answering machine has become popular recently, it is complicated to switch to the answering machine mode each time when the user leaves the place where the telephone is installed, and the answering machine mode is not set to the first answering machine except when going out. In addition, even in the answering machine, the caller cannot talk to the phone one-sidedly, and often hangs up without saying a message. Therefore,
In the case of an important requirement, the timing of obtaining information will be missed even at home.
