Abstract

PURPOSE:To increase the sound volume of an external call tone and of voice of opposite party by sounding a ringer tone from a ringer when a call comes from the opposite party and supplying an output of a ringer driver to a speaker for a charger. CONSTITUTION:When an external phone call comes through a general telephone line, a ringer 4 rings, a signal from a ringer driver 3 is sent to a signal superimposing circuit 10 and sent to a charger unit 9 via a charging terminal 7. The signal is amplified by a speaker amplifier 11, which drives a speaker 12 for charger. In the case of replay without hooking-off of a slave set for the incoming telephone call, the voice of the opposite party is sent to the speaker 12 from a speaker amplifier 1 via the circuit 10, the terminal 7 and the amplifier 11. Thus, a large and clear sound not obtained in a conventional telephone set is generated and the taking is confirmed in a large and clear voice.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application: j This invention relates to a cordless telephone device, and particularly to improvements in its speaker section.

[Prior Art] FIG. 2 is a block diagram showing, for example, a speaker section of a conventional cordless telephone device, in which (1) shows a speaker amplifier;
(2) is a speaker. The speaker amplifier (1) is a circuit that amplifies the voice of the other party supplied from the outside via a general telephone line, and the speaker (2) is driven by the output of this speaker amplifier (1). (3) is a ringer driver, and (4) is a ringer. The ringer driver (3) is a circuit that drives the ringer (4) in response to a call from the other party and generates a ringer sound. (5) is the slave unit power supply, (6
) is a protection diode, and (7) is a charging terminal of the charger unit (9). The handset power supply (5) is a circuit that supplies power voltage to the handset of the cordless telephone device, and the handset power supply (5) is connected to the charger unit ( A predetermined voltage is supplied from 9). The charger unit (9) is a unit containing a constant voltage power supply (8), and the AC 100V power taken in by the constant voltage power supply (8) is made into a constant voltage by the constant voltage power supply (8), and the charging terminal (7) and the protection diode (6) to the slave unit power supply (5).

Next, the operation will be explained.

When you receive a call from outside through a regular telephone line,
The ringer driver (3) causes the ringer (4) to ring, thereby informing the user that there is an incoming call from outside.

When the ringer sound is emitted from the ringer (4), the user picks up the handset and makes a call to the outside. At that time, the other party's voice is sent to the speaker (2) via the speaker amplifier (1), so that the user can hear the other party's voice close to his or her ears.

[Problems to be Solved by the Invention] Since the conventional cordless telephone device was configured as described above, the ring tone and the other party's voice from the outside could not be emitted from the speaker (2) or the ringer (4) of the handset. It must be done. Therefore, in order to make the ringer and the other party's voice louder, the shape of the speaker (2) or ringer (4) must be made larger. As described above, there have conventionally been problems in that it is necessary to increase the size of the handset and the weight is heavy.

This invention was made to solve the above-mentioned problems, and it is possible to increase the ringing sound from the outside and the voice of the other party without increasing the size and weight of the handset. purpose.

[Means for Solving the Problems] A cordless telephone device according to the present invention includes a signal superimposing circuit that superimposes output signals of a driver and a speaker amplifier, and a charger unit or a charger that amplifies the output of the signal superimposing circuit. It is characterized by comprising a speaker amplifier and a charger speaker driven by the charger speaker amplifier.

[Operation] In the present invention, when a call is made by the other party, the ringer emits a ringer sound, and the output of the ringer driver is supplied to the charger speaker via the signal superimposition circuit and the charger speaker amplifier. As a result, a ringing sound is emitted from the charger speaker.

Further, during a call, the other party's voice is emitted from the speaker amplifier, and the output of the speaker amplifier is supplied to the charger speaker via the signal superimposition circuit and the charger speaker amplifier. As a result, the other party's voice is emitted from the charger speaker.

This charger speaker can be configured separately from the handset of the cordless telephone device, and a large one can be used if necessary.

Therefore, the ring tone from the outside and the voice of the other party can be made louder without increasing the size or weight of the handset.

[Example code] Hereinafter, one embodiment of the present invention will be described based on the drawings.

In Fig. 1, (10) is the signal superimposition circuit in the handset, (
11) and (12) are a speaker amplifier and a charger speaker provided in the charger unit.

In this embodiment, when a call is received from outside through a general telephone line, the ringer (4) rings as in the conventional case.
At the same time, the signal from the ringer driver (3) is sent to the signal superimposition circuit (10) and sent to the charger unit (9) via the charging terminal (7). This signal is amplified by the speaker amplifier (11) and the charger speaker (12) makes a sound.

In addition, when a call is received as described above, when the handset is raised, the operation is the same as before, but when the handset is answered without raising the handset, the other party's voice is superimposed as a signal from the speaker amplifier (1). The signal is sent to the charger speaker (12) via the circuit (10), the charging terminal (7), and the speaker amplifier (11).

Further, in the above embodiment, the charging terminal (7) is connected to the signal superimposition circuit (
10) is connected, but if they are separated separately, power supply noise etc. will be removed. As a result, a clearer sound is generated, and in addition to the same effect as in the above embodiment, the sound quality is further improved.

[Effects of the Invention] As described above, according to the present invention, by providing the charger speaker and generating the other party's voice and ringer sound, it is possible to generate a loud and clear sound that has not been possible until now. , you can confirm calls with a loud and clear voice.
