Abstract

PURPOSE:To utilize a head set as a telephone terminal equipment by inserting a modular plug to a modular connector fitted to a telephone set so as to connect a microphone and the speaker of the head set to a telephone set circuit in place of the transmitter/receiver of the telephone set and short-circuiting effec tively a hook switch. CONSTITUTION:Modular plugs 13a, 14a, 15a and modular connectors 13b, 14b, 15b are provided to the head set 10 and a telephone set main body, and when the plug 13a (not shown) is connected to the connector 13b, a relay is activated. In inserting the plugs to the connectors, a relay contact 16 closes terminals (a, c) and opens terminals (a, b). A contact 17 closes terminals (d, f) and opens terminals (d, e). Then terminals (g, h) of the contact 18 are closed. Then the contact 18 plays a role of a hook switch of the head set 10. Thus, the microphone 11 and the speaker 12 are connected to the telephone set circuit in place of the transmitter 4 and the receiver 5, and the contact 18 is closed and the telephone set circuit is brought into the outgoing state.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a headset switching method for a telephone, and particularly to a headset switching method that allows dialing.

Headsent has been widely used in the past, but it has the disadvantage that it plays an auxiliary role to a telephone and cannot be used as a telephone terminal, and there has been a need to improve this problem.

[Conventional technology]

FIG. 2 is a diagram showing an example of a conventional telephone.

In the figure, Ll and L2 are connection terminals, ■ is a hook switch, and 2
is a dial sending circuit, 3 is a transformer, 4 is a transmitter, 5 is a receiver, 6.9 is a capacitor, 7.8 is a resistor,
20 is a conventional headset, 21 is a headset microphone, and 22 is a headset speaker. The same symbols represent the same objects throughout all the figures below.

A conventional telephone set 20 is composed of a microphone 21 and a speaker 22. The microphone 21 is connected in parallel to the transmitter 4 of the telephone, and the speaker 22 is connected in parallel to the receiver 5. It is used primarily for the purpose of intercepting telephone calls.

Conventionally, by inserting the plug into the connector, the contact u
, v, w, and x are short-circuited, and when the plug is removed from the connector, the contacts u, v, v, and x are opened.

[Problem that the invention seeks to solve]

However, compared to conventional telephones, Dosenoto has the advantage of being lightweight, small, and can be used by attaching it to the head, but it does not have a dialing function, so it cannot directly make or receive calls. .

The object of the present invention is to eliminate the drawbacks of the above-mentioned conventional systems and provide a headset that can make direct calls.

[Means for solving problems]

A solution to the problem is to attach a modular connector to a telephone, insert a headset into said modular connector via a modular plug, and thereby use the microphone of said headset instead of the telephone's handset. This is accomplished by connecting the speaker of the headset instead of the handset of the telephone, and shorting the hookswitch by a contact instead of the hookswitch of the telephone.

[Operation] According to the present invention, by inserting the modular plug into the modular connector attached to the telephone, the microphone and speaker of the headset are connected to the telephone circuit instead of the transmitter and receiver of the telephone, and the hook switch is connected to the telephone circuit. Since it is effectively short-circuited and a dial can be sent using the dial sending circuit of the telephone, the effect is that it can be used as a telephone terminal.

〔Example〕

FIG. 1 is a diagram illustrating an embodiment of a headset switching method according to the present invention.

In the figure, 10 is a headset according to the present invention, 11 is a microphone of the headset, 12 is a Hesodo Sesotho speaker, 13a, 14a, and 15a are modular plugs, respectively.
13b, 14b, and 15b are modular connectors, respectively;
19 is a relay, 16, 17, and 18 are each a relay 19
This is the point of contact.

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

The headset 10 according to the present invention is composed of a microphone 11 and a speaker 12 like the conventional headset,
The microphone 11 and the speaker 12 are modular plugs 13a, 14a, 15a having an integrated structure.
connected to.

Modular connectors 13b, 14b, and 15b are also of integral construction and are attached to the telephone body. Modular plug 13a is connected to modular connector 13b, modular plug 14a is connected to modular connector 14b, and modular plug 15a is connected to modular connector 15b.

Although not shown, when the modular plug 13a is connected to the modular connector 13b, the relay 19 is activated.
When the modular plug 13a separates from the modular connector 13b, the relay 19 becomes inactive.

When the modular plugs 13a, 14a, 15a are not connected to the modular connectors 13b, 14b, 15b, that is, when the headset 10 according to the invention is not used, the contacts 16, 17, and 18 of the relay 19 are Take the position shown in Figure 1. Note that the contacts 18 of the relay 19 serve as a hook switch for the headset 10 according to the invention.

That is, the contact 16 is closed between terminals a and 2, and is open between terminals d and e. The contact 17 is closed between terminals d and e, and open between terminals d and f. Further, the terminal g of the contact 18 is open.

Therefore, the transmitter 4 and the receiver 5 are connected to the telephone circuit, and the telephone circuit operates normally.

However, when the modular plugs 13a, 14a, 15a are inserted into the modular connectors 13b, 14b, 15b,
The contact 16 is closed between terminals d and e, and is open between terminals a and s. Contact 17 is closed between terminals d and f, and closed between terminals d and f.
Terminal e is open. Also, the terminal a to terminal 1 of the contact 18 is closed.

Therefore, the microphone 11 is connected to the telephone circuit instead of the transmitter 4, and the speaker 12 is connected to the telephone circuit instead of the receiver 5, and since the terminal g of the contact 18 is closed, the telephone circuit enters the transmitting state.

In this state, when the operator operates the dial sending circuit 2, a desired dial signal is sent to the subscriber's line, and it becomes possible to start a call by performing the same operations as with a conventional telephone.

When the call ends, the modular plugs 13a, 14a,
By unplugging 15a from the modular connectors 13b, 14b, 15b, the telephone circuit using the transmitter 4 and receiver 5 is put into a standby state.

In this way, according to the present invention, it is possible to use the dossette 10 to make outgoing calls and make calls.

C. Effects of the Invention] As described above in detail, the present invention has the great effect of allowing direct transmission using head cents.
