Abstract

PURPOSE:To call a desired other party of the incoming side by sending out a sound signal from the transmitting side as a voice from a loudspeaker, by constituting the titled telephone set so that a line can be switched automatically to the loudspeaker from a receiver, when the number of times of an incoming signal which arrives at the receiving side has exceeded a prescribed number of times. CONSTITUTION:When an incoming signal arrives through a line 150, the number of times of intermittence of its incoming signal is counted by a counting means 120, and whether a counting value of the number of times of intermittence of its incoming signal has exceeded a prescribed number of times or not is discriminated by a frequency discriminating means 140. In this case, if its counting value has exceeded the prescribed number of times, when a receiver 110 is not picked up, a switching means 140 switches and connects the line 150 to a loudspeaker 100 from the receiver 110. As a result, a sound signal from the transmitting side is sent out as a voice from the loudspeaker 100.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone speaker switching system for switching a line from an exchange between a 75-phone machine and a speaker.

[Conventional technology]

In the case of a conventional speaker-switching machine, even if it is known that the desired party is on the receiver 111;, until the other party picks up the receiver, the calling party will receive 1g of audio from the calling party.
I couldn't get the message to be transmitted. Here, a conventional telephone speaker switching system will be explained with reference to FIG. FIG. 2 is a block diagram of a conventional manual telephone speaker switching system.

This conventional telephone speaker switching system is based on the telephone (speaker device 1oo, g talker 11o, switching means 140, turn u
15o. In FIG. 2, the switching means 140
1. Therefore, when the line 150 is connected to the speaker device 100, as soon as the connection to the receiving side is completed, the M-voice signal from the calling side is immediately transmitted as voice from the speaker device tioo on the called side. Call. However, if (, n (
In the Ill telephone, the line 150 is connected to the switching means 140.
When the caller is on the handset 110, the caller receives an incoming call (,4Ullll), just like a normal telephone.
There is a drawback in that while the user picks up the receiver 110, the user only hears the ringing tone and cannot transmit the voice signal from the calling party to the desired party on the called party.

[Problems that the invention is supposed to solve]

If a telephone is located in an environment with loud external noise and it is a national disaster for the telephone to hear the ringing of the telephone's bell, the person who should handle the telephone even if it is easy to hear the ringing of the telephone's bell. In cases where the telephone is not specified, the chances of the telephone being operated off-hook are reduced even if the telephone bell rings, and in some cases, the opportunity to do so is completely eliminated. There is a point.

[Means for Solving Problem 7-1] The telephone speaker switching system of the present invention has financial means for financing the number of interruptions in incoming signals that arrive via the line from the speaker device and the exchange, and It has a frequency identification means for identifying whether or not the number of intermittent incoming signals exceeds a predetermined number, and a switching means for switching the line between the speaker device and the receiver.

〔Example〕 Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

In this embodiment, a telephone set includes a speaker device 100 and a receiver 11.
0, counting means 120, number identification means 130, switching means 140, and line 150. Next, the operation of this embodiment will be explained. 1st
In the figure, a line 150 is connected to a telephone receiver 110 in a normal state. Here, when a call is received from another party and an incoming signal arrives via the line 150, the counting means 120 counts the number of intermittent times of the incoming signal, and the count value of the number of times the incoming signal is interrupted is determined by the number identifying means 140. It is determined by age whether the number of times exceeded a predetermined number. Here, if the counted value exceeds a predetermined number of times and the handset 110 is not picked up, the switching means 140 switches and connects the line 150 from the handset 110 to the speaker device 100. As a result, the audio signal from the calling side is sent out as audio from the speaker device 100. Furthermore, if the handset 110 is picked up before the count value exceeds a predetermined number of times, the phone 1150 and the handset 110 remain connected, so that the audio signal from the calling party is not transmitted from the handset 110. Sent as audio.

〔Effect of the invention〕

In conventional telephones with a manual speaker switching system, unless the receiver had switched the speaker, the caller could not call any number of parties on the receiver's side through the speaker device. According to the present invention, if the number of incoming signals arriving at the receiving side exceeds a predetermined number, the line is automatically switched from the handset to the speaker device, and the audio signal from the calling side is sent out as audio from the speaker device. This has the effect that the called party can call the desired party.
