Abstract

PURPOSE:To improve the convenience of use of a slave set of a cordless telephone set by devising the slave set of the cordless telephone set such that either loudspeaking reception by a speaker or usual reception state by a receiver is manually selected for the received voice from a talking opposite party. CONSTITUTION:When a slave set main body 20 is called while it is place on a charger, a received voice is sounded from a speaker 8 by depressing an on- hook button 24a and the received voice is heard without taking up the slave set main body 20 in hand. Then the usual talking to mute the sound of the speaker 8 is implemented by lifting up the slave set main body 20. Moreover, when a call comes while the slave set main body 20 is not placed on the charger, the received voice is sounded from the speaker 8 by depressing the on-hook button 24a. Thus, the output from the speaker 8 or the output of a receiver 17 is selected manually or automatically and the convenience of use of the cordless telephone set is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a base unit connected to a wired line and a slave unit of a cordless telephone connected to a wireless line.

[Conventional technology]

Figure 3 shows the main body of the telephone (1
) is a block diagram of a telephone in which a handset (2) is connected.

A communication circuit (6) connected to the output side of the circuit via the dialer circuit (5), a transformer (7) connected to the output side of the diode bridge circuit (4), and a secondary side of this transformer (7). A speaker (10) connected via a switch (8) and an amplifier circuit (9), and a melody IC circuit (1) connected to the above communication circuit (6) and the above amplifier circuit (9).
1), the dialer circuit (5), and the telephone call circuit (6).
a key switch (12) for supplying signals to the communication circuit (6) and a control section (13) that receives signals from the key switch (12) and controls the melody IC circuit (11).
and a power supply circuit (15) having a backup power supply (14) and connected to an external AC adapter.

In addition, the above handset (2) is a microbon (16)
and a receiver (17), and is connected to the telephone line (6) with a machine cord (18).

Now, operate the key switch (12) and switch (8).
) is supplied to the control section (13), and when the switch (8) is turned on, the audio signal received from the line via the connector (3) is transferred to the diode-bridge circuit (
After the polarity is adjusted in step 4), the signal is outputted as amplified sound from the speaker (1o) via the transformer (7), switch (8) and amplifier circuit (9).

In this receiving state, if you press the key to cancel the loudspeaker call or hook up the handset (2), the control unit (13) that receives this key operation signal or hook-up signal turns off the switch (8) and turns off the handset (2). 2) becomes a normal conversation state. Here, the control unit (13) constantly detects the state of the handset (2) in order to switch between the loudspeaker reception state and the normal call state by hooking up/down the handset (2).

Note that non-voice sounds such as voice messages, melody sounds, ringer sounds, etc. produced by the melody IC circuit (11) are output from the speaker (10) via the amplifier circuit (9), regardless of the state of the switch (8). Amplified sound can be generated.

By providing the speaker (10) in this way, it is possible to hear the received voice and key click sound even when the handset (2) is not hooked up.

On the other hand, cordless telephones are known in which a slave unit having a handset is wirelessly connected to a base unit connected to a wired line. This cordless telephone has the advantage of being able to carry the handset freely.

In such cordless telephones, the receiver is usually the only member capable of emitting sound. Therefore,
There is no incoming voice, and a ringer tone is also emitted from the receiver. However, the volume of the ringer sound is higher than that of the received voice, and when the ringer sound is emitted with the receiver close to the ear, the shock to the ear becomes very large.

Therefore, it has been proposed to provide a sound generating member in the handset of a cordless telephone separately from the receiver.

For example, in Japanese Patent Application Laid-open No. 60-69921, a cordless telephone handset is provided with a sounding body with an interest separately from a receiver for receiving a call, and is also provided with a discrimination detection means for discriminating and detecting a ringer signal and voice. When a sound is detected, a ringer sound is generated from the gain sounding body, and when a voice is detected, the separate sounding body is muted and the sound is controlled so that the sound is generated only from the receiver. According to this cordless telephone, since the ringer sound is generated from a sounding body separate from the receiver, the impact on the ears can be reduced. Incidentally, the provision of a sounding body (speaker) in the handset is also disclosed in Japanese Utility Model Application Laid-Open No. 63-38438.

[Problem to be solved by the invention]

As described above, telephones in which the main body of the telephone is connected to a line and a handset is connected to the main body of the telephone by a device string are conventionally known to be equipped with a speaker so as to enable loud voice reception. However, such telephones have a problem in that the range of movement of the handset is limited.

On the other hand, it is known that a cordless telephone handset is provided with a sounding body separate from a receiver for receiving voice calls.

However, this gain sounding body is used for non-speech sounds such as ringer tones or key click sounds, and cannot amplify voices. This is because the sounding body of the cordless handset was made for the purpose of softening the impact on the ears.

The handset is basically carried in the hand of the person making the call, and there was no idea that the received voice would be generated from a sounding device separate from the receiver.

However, the handset is not necessarily held in the hand of the caller, but may be placed on the charger or table.

Therefore, the inventor of the present invention thought that it would be possible to further improve the usability of the cordless telephone if it were possible to listen to the received voice from the handset without having to put the receiver to the ear.

The present invention was made in view of the above-mentioned problems, and an object thereof is to provide an easy-to-use cordless telephone handset that can amplify and receive the voice of the other party.

[Means to solve the problem]

A handset of a cordless telephone according to the present invention includes a speaker for amplifying received audio, which is provided separately from a telephone receiver, a switching means for switching the speaker to an amplifying state or a mute state, and a switching signal for the switching means. and a control means for switching and controlling the switching means in response to a switching signal input by the manual inputting means.

[Effect]

In the handset of the cordless telephone according to the present invention, by manually inputting a switching signal using the manual input means, the control means inputting this switching signal controls switching of the switching means.
It is possible to switch between a loudspeaker receiving state using a speaker and a normal receiving state using a receiver, thereby improving usability of a slave unit of a Court 1 Nos telephone.
