Abstract

PURPOSE:To easily identify an incoming telephone set in a very short period if plural telephone sets receive a call simultaneously by forming a unique telephone set whose incoming tone is varied through the use of an independent incoming information storage means loaded from the outside of a telephone set case. CONSTITUTION:A voice information storage means 44 is a separate body and connected to an interface 45 from the outside of a telephone set 46. A signal sent through lines L1, L2 is separated 7 to activate a voice synthesis circuit 41. In this case, the circuit 41 transfers the storage from the voice information storage means 44 via the interface 45 to reproduce the voice, amplifies 42 and laudens 14. In giving an optional voice to the voice information means 44, the incoming tones of plural telephone sets provided in the same closed space are identified clearly and immediately.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an incoming call sound switching device for a telephone that can arbitrarily select a ring tone in a ring tone generating means for a telephone.

(Prior Art) Conventional telephones include a magnetic bell, a buzzer, a tone ringer, and recently, ICK, which generates a chime ringer, as calling parts that acoustically notify an incoming call signal.

For example, Research Application Report, Volume 33, [No. 6].

(1984:1, Nippon Telegraph and Telephone Public Corporation Musashino Telecommunications Research Institute, Toshihiko Yamamori et al., Circuit structure of electronic telephones, pages 123 to 135, using a tone ringer).

FIG. 2 is a basic configuration diagram of an electronic telephone circuit according to the prior art (.zeta.) described in the above-mentioned publication.

This conventional electronic telephone has adopted a major electronic circuit technology for the telephone circuit due to the progress of OLSI technology in recent years, and by realizing these on a single LSI chip, the degree of freedom in design has been improved. In addition to the basic functions of a telephone, this telephone is equipped with additional functions such as dual-dial dialing, on-hook dialing, handset amplification, and tone ringer.

In this description of the prior art, the tone color switching tone ringer device K related to the gist of the present invention will be limited, and other descriptions will be omitted.

In FIG. 2, 1 is a tone ringer, 2 is a sounder, and 3 is a crystal oscillator.The tone ringer 1 employs a highly efficient circuit and a highly sensitive sounder 2 to obtain a sufficient ringing volume. The ring tone has two audible frequencies, two peaks 1024 and 136 of the sensitivity characteristics of sounder 2.
I'm trying to tune it to 5Hz.

The tones are synthesized by a frequency dividing circuit clocked by a 32.8 kHz crystal oscillator 3, and three types of tones are selected.

Also, the volume can be adjusted in three stages.

(Problem to be Solved by the Invention) However, in conventional devices for acoustically announcing the incoming call signal of telephones, the magnetic bell, buzzer, tone ring, etc., which are most commonly used in the current incoming call system, do not change the pitch of the sound. Since it can only be used to make noises and use special signal tones, it has disadvantages such as when multiple telephones are installed in the same space and calls arrive at the same time, it takes time to identify the incoming telephone. Ta. In addition, since the melody oscillation circuit is built into the circuit that makes up the telephone system for IC-generated melodies, the user cannot freely select the ringtone, and if they wish to select one, they must modify the circuit or use the telephone. The disadvantage was that it was expensive to purchase and replace.

An object of the present invention is to provide a telephone that solves the difficulty of identifying telephones that generate standardized ring tones.

(Means for Solving the Problems) The present invention incorporates an independent incoming call information storage means from outside the telephone casing in order to give the telephone individuality by changing the ring tones. In a telephone having means for detecting an incoming signal from a connected telephone line using arbitrary sounds, a voice information storage means in which various voices that can be installed and replaced from the outside are registered and stored;
a connector into which the voice information storage means is inserted, a voice synthesis circuit that synthesizes the information stored in the voice information storage means into voice, an amplification circuit that amplifies the output of the voice synthesis circuit, and the voice information storage. An incoming voice switching device for a telephone is constructed, which includes an incoming voice switching circuit for switching between the incoming voice from the means and an incoming call generation means built in the telephone body, and means for connecting to each circuit of the telephone body.

(Function) Since the present invention is configured as described above, it is possible to obtain a unique telephone with various ring tones due to the independent incoming call information storage means fitted from outside the telephone housing, and it is possible to obtain a unique telephone with various ring tones. Even if the telephones are installed in a space and receive calls at the same time, it is now possible to easily identify the receiving telephones in an extremely short period of time.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory diagram of a circuit configuration of an embodiment of the present invention.

In the figure, 41 is a speech synthesis circuit, 42 is an amplifier circuit, 4
3 is a power adapter. The power adapter 43 is used by being plugged into a household outlet during normal use, but each circuit may be driven by the internal power source 19 using a battery. 4
Reference numeral 4 denotes an audio storage means, and the audio storage means 44 is, for example, an audio memory card. 45 is an interface, and the interface 45 is an interface between the voice storage means 44 and the voice synthesis circuit 41. 46 is a telephone, 47
is a handset, and 49 is a housing body.

An incoming signal detection circuit 7, a voice synthesis circuit 41, an amplification circuit 42, a speaker 14, an interface 45, an internal power supply 19, and a connection line are provided in a housing body 49 of the telephone set 46 as shown by a dashed line.

The audio information storage means 44 is provided separately and independently, and is configured to be inserted from the outside of the telephone 46 via a connector (not shown) and connected to the interface 45.

In such a configuration, the operating principle is as follows.

The signal transmitted through the telephone line L1L2 is separated by the incoming signal detection circuit 7 and activates the voice synthesis circuit 4. At this time, the voice synthesis circuit 41 reads the voice information storage means 44.
The recording signal is transferred through the digital interface 45, and the voice is reproduced in the voice synthesis circuit 41, which is amplified by the amplifier circuit 42 and amplified by the speaker 14.

Any audio information is input into the audio information storage means 44.

(Effects of the Invention) Since the present invention is configured as described above, any voice information can be inputted from outside the phone case using the voice memory card of the voice information storage means, so that incoming signals of various voices can be input to one phone. This system has the advantage that it can be reproduced by any telephone set, and since the telephone set can adopt any ringtone of various voice information, it has the effect that the ringtones of a plurality of telephones installed in the same closed space can be clearly and easily identified.
