Description

[Detailed explanation of the idea] The present invention relates to a transmission mechanism for a call signal.

Conventionally, the use of telephones with enhanced acoustic effects has been increasing, such as by amplifying telephone calls using a speaker installed in the in-flight base cellar l-, and by making a ringing signal ring at a moderate volume with a tone ringer at a moderate volume.

The present invention relates to a tone ringer telephone that does not require a special ringing speaker when making an incoming call and is composed of an electromagnetic transmitter and a receiver.

An example of the arrangement and configuration of parts of a conventional telephone will be explained with reference to the external view of FIG.

In the figure, reference numeral 1 denotes a handset, and the handset 1 houses a transmitter 2 and a receiver 3.

Reference numeral 4 denotes a pace set, and the base cell IIc houses a calling speaker 5, and is provided with a resonator 6 and a resonator radiation hole 7 for the speaker.

In this case, the transmitter/receiver may be used as a speaker for incoming calls, but if the handset is stored inside the handset, there is no resonator section that effectively extracts the sound pressure from the sound source, so sufficient directional characteristics and sound quality cannot be obtained. It is structurally unsuitable.

The present invention eliminates such structural defects.

The present invention is characterized by comprising a handset housing a transmitter and receiver, and a pace set used in combination with the handset, and an acoustic resonator is formed at a portion of the pace set opposite to the handset receiver. In a telephone used as a ring signal speaker, a sealing protrusion is provided on the contact surface of the pace set with the handset of the second set to form an acoustic space (2), and a hook button attached to the pace set is lowered. As if configuring the acoustic space V0, the acoustic space ■2
This is a telephone in which an acoustic resonator of a calling signal speaker is constituted by (1) and (1).

The configuration of the telephone according to the present invention will be explained below with reference to the drawings.

FIG. 2 shows an embodiment of the present invention in which the receiver is configured as a calling speaker.

In the figure, 1 is a handset, 2 is an electromagnetic transmitter, 3 is an electromagnetic handset, 4 is a pace set, 6 is a resonator, and 7
9 is a resonator radiation hole, and 9 is a hook button.

FIG. 3 is a sectional view taken along the line AA' in FIG. 2, showing the detailed structure of the present invention.

The illustrated state shows a state in which the handset 1 is attached to the pace set 4.

In this state, there is a mutual gap space (2) between the handset 1 and the handset cover guide 4-1', and an acoustic space (1) is provided between the cover 4-1 and the cover plate 8 in the base set 4 on the other side.

The present invention is a handset in such a state of waiting for an incoming call, in which a resonator is formed by connecting the space V2 and the acoustic space V□ by means of a hook button 9 that moves downward.

That is, the sound pressure of the speaker 3 is effectively guided to the resonator sections (2) and (1), and the ringing tone is emitted from the sound emission hole 7.

Reference numeral 11 is a cushioning rubber, which is effective in improving the sealing effect of the acoustic space (1) when the hook button 9 is pressed.

Reference numeral 10 is a converter which, when the handset 1 is removed, causes the hook button 9 to be raised to the position shown by the dotted line by the spring 12.

As a result, the acoustic space ①, , is blocked by the hook button 9, and a foreign object is inside the acoustic space V0.

Infiltration of dust, etc. can be prevented, and acoustic characteristics can be maintained over a long period of use and maintenance can be improved.

Regarding the shape shown in FIG. 3, for example, the shape and position of the hook button 9, the resonator forming space (1) and (2)
It goes without saying that the method for combining the two can be modified as appropriate.

A telephone with this configuration does not require a dedicated speaker in conventional telephones, thereby saving space and contributing to miniaturization of the telephone.
