Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a cordless telephone, and in particular, to a cordless telephone that has a built-in speaker, and by switching between this and an ear receiver, it is possible to monitor audio signals using the speaker. related to cordless telephone handsets.

[Prior Art] In a conventional cordless telephone, an operation section such as a numeric keypad is provided on a handset, and the user picks up the handset and operates the operation section.

Regarding this, see, for example, the Institute of Electronics, Information and Communication Engineers' ``Electronic Information and Communication Handbook 1988J'' (Ohmsha, 1988).
You can refer to the descriptions in Volumes 32 and 36 (March 2016).

[Problem to be solved by the invention]

In the above-mentioned conventional technology, since the handset is equipped with an operation section such as a numeric keypad, it is impossible to perform the operation while listening to the receiving sound such as a dial tone when making a call. Especially when operating under a PBX, in order to check the internal and external dial tones, place the ear receiver of the handset to your ear before and after key operations.
There was the annoyance of having to check the dial tone.

Furthermore, in the above conventional technology, after making a call, until the called party picks up the call, the ear receiver of the handset is held against the ear.
Since I had to wait while listening to the ringback tone, I also had the problem of having my hands full during that time. Furthermore, in the above-mentioned prior art, even when interrupting the audio of a so-called telephone service such as a weather forecast, it is necessary to listen by holding the ear receiver of the handset to the ear, which has the same problem as above.

Also, if the caller puts the call on hold until the person on the other end of the call calls the person you are directly talking to, hold the ear receiver of the handset to your ear to know when the hold tone will be released. I had the same problem as above.

The present invention has been made in view of the above circumstances, and its purpose is to solve the various problems described above in the conventional technology, add a speaker, and make it possible to switch between this and an ear receiver. Another object of the present invention is to provide a cordless telephone handset that allows audio signals to be monitored using the speaker.

[Means for Solving the Problems] The above-mentioned object of the present invention is to provide a cordless telephone handset equipped with a microphone for sending speech and an ear receiver for receiving calls, in addition to the ear receiver, a speaker for receiving calls, and an ear receiver for receiving calls. This is achieved by a cordless telephone handset characterized in that it is provided with means for selecting whether to transmit the information from the ear receiver or from the speaker.

[Effect]

In the cordless telephone handset according to the present invention, in addition to the conventional functions, a speaker is added and it is possible to switch between this and an ear receiver.
This makes it possible to monitor the audio signal using the speaker, eliminates the hassle of operations when making a call and during a call, and also frees up the user's hands for a relatively long period of time. be.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a handset of a cordless telephone that is an embodiment of the present invention, and FIG. 2 is a block diagram of the base unit. 3 is a radio frequency (RF) circuit that modulates an audio signal into a wireless signal or a wireless signal into an audio signal; 3 is an audio signal (AF) circuit that handles audio signals in the audible frequency band;
) circuit, 4 is a speech circuit that converts the 4-wire circuit for transmitting and receiving into a 2-wire circuit on the line side, and 5 is a line input/output circuit that controls DC current, detects the state, sends dial pulses, etc. There is.

Further, 6 is an incoming call detection circuit that detects incoming calls from the line;
8 is a line protection circuit, 8 is a dialer that sends out a DTMF signal, 9 is a ringer that sounds a ring tone, and 10 is a CPU on the base unit side that controls these. Note that 12 is a new speaker installed in the handset, and 13 is the speaker 1.
14 is an ear receiver, 15 is a microphone, 16 is an analog switch for switching between the speaker 12 and the ear receiver 14, and 17 is a CPU on the handset (child unit) side that controls these. It shows.

Note that the operation unit 11 of the handset includes a numeric keypad and function keys 18. Speaker selection button 19. A call button 20 is provided, and a speaker selection button 1
9 turns the speaker mode ON10 F F every time you press -
It is designed to switch between. In addition, the speaker selection button 19 has the function of switching to the speaker side and capturing one wireless connection line at the same time when pressed in the idle state.The call button 20, when pressed in the idle state, It has a function to capture one wireless connection line at the same time as switching to the ear receiver (handset) side.

In addition to the above-mentioned circuits, the base device has a detection means for detecting the setting of a handset and a power supply section, and the handset is equipped with a device consisting of a battery as described above. The operation of the constructed cordless telephone of this embodiment will be explained below. Since users usually want to spend as little time holding the handset as possible, they do the following.

The user first picks up the handset from the base unit and presses the speaker button on the handset. As a result, in this telephone, a wireless connection is established between the handset and the base unit, and when the base unit starts a line acquisition operation (0 line capture operation), the station side sends out a dial tone, which is a wireless connection. is sent to the handset and output from the speaker on the handset. The user only needs to confirm this dial tone and perform dial operations.

By the above-described operation, after performing a calling operation, the user can hear audio signals from the station, such as a ringback tone and a busy tone, from the speaker until the called party picks up. During this time, there is no need to hold the handset to the ear, so the user remains untethered to the telephone. Once the called party is connected and the called party's voice is confirmed, the user presses the call button to switch to handset mode,
Make a call using the handset.

If the purpose of the call is simply to listen to a telephone service such as a weather forecast, the user can simply switch to speaker mode after making the call and listen to as much information as necessary.

Additionally, if the other party puts the call on hold during a call, the user can press the speaker button again to switch to speaker mode and monitor changes in the other party's status using the earphone tone.

According to the above embodiment, the user can monitor the audio signal on the line using the speaker, so the user can monitor the audio signal on the line using the speaker.

This frees you from the hassle of having to hold the ear receiver of the handset to your ear before and after pressing keys to check the dial tone of an outside line, and it also frees up your hands for more time. It has the effect of becoming.

In the above embodiment, an example was shown in which the speaker mode is selected using the speaker button, and the switching to the handset mode is then performed using the call button, but it goes without saying that these control means may be combined as appropriate.

[Effects of the invention] As described above in detail, according to the invention, in a cordless telephone handset that is equipped with a microphone for sending and an ear receiver for receiving calls, in addition to the ear receiver, a speaker for receiving calls and a speaker for receiving calls are provided. By providing a means for selecting whether the incoming call sound is transmitted from the ear receiver or the speaker, it is possible to realize a cordless telephone handset in which the audio signal can be monitored by the speaker. This has a remarkable effect.
