Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable radio telephone having a winding cord type earphone mounted on a portable telephone or a home cordless telephone handset.

[0002]

2. Description of the Related Art In a conventional portable telephone, a speaker and a microphone are usually provided inside the portable telephone. FIG. 3 shows the mobile phone 100. Here, 10 is a speaker, 60 is a microphone, 70 is an earphone connector, 90 is an antenna unit, and 91 is an antenna body.

When the earphone 80 cannot hear the received audio signal, the jack 82 of the earphone 80 is connected to the earphone connector 70 so that the earphone 80 can listen to the received audio signal.

However, since the earphone 80 and the mobile phone 100 are separated from each other, it is necessary to take out the earphone from a storage device storing the earphone and mount it when using the earphone. In some cases, the user may forget the storage location. Since the cord 81 between the earphone 80 and its jack 82 is also long, storage is troublesome.

Embodiments of the present invention will be specifically described below with reference to the drawings. 1A is a front view of the mobile phone 100, FIG. 1B is a side view thereof, and FIG. In the side view of (b) and the back view of (c), the upper part is shown in a sectional view.

FIG. 2B is a cross-sectional view showing the positions of the front end portion 80a of the earphone 80 and the antenna body 91 of the antenna section 90 which are housed from the side surface and the side surface of the speaker 10 fixed to the front and supported on the side surface. .

FIG. 2C is a sectional view showing an earphone 80 in which an earphone support 15 is formed on the side surface of the mobile phone 100 in the form of a hole, and the earphone 80 is detachably supported by the earphone support 15. Indicates a state in which Reference numeral 15 is formed of an elastic member.

Cord 81 connected to earphone 80
Indicates a state where the cord has been wound by the cord winding mechanism 20.

Reference numeral 30 denotes an earphone sensing mechanism. When the earphone 80 is set on the earphone support 15, the earphone tip 80a pushes the contact short-circuit plate 32 against the spring 33, and as a result, the earphone sensing contact 31 is short-circuited. Let it.

Reference numeral 35 denotes a switch control unit, which judges ON / OFF of the sensing contact connection terminals 36 and 37, and turns ON
In this case, the corresponding signal is output from the control signal output terminal 38.

A changeover switch 40 has a first output terminal 4 connected to an earphone 80 and a second output terminal 42.
Is connected to the speaker 10, and the input terminal 43 is
This is a reception audio signal input terminal for inputting a signal 50 obtained by FM detection of the reception electromagnetic wave 00. Control signal output terminal 3
8 is received by the control signal input terminal 44 and when the sensing contact connection terminals 36 and 37 are ON, the input terminal 43 is controlled to be connected to the second output terminal 42, and the sensing contact connection terminal Input terminals 4 when 36 and 37 are OFF
3 is controlled so as to be connected to the first output terminal 41.

FIG. 2 shows the earphone 80 connected to the earphone support 15.
And listening to the sound using the earphone 80. In the case of FIG. 2, the spring 33 is extended to separate the contact short-circuit plate 32 from the earphone sensing contact 31, and the sensing contact connection terminals 36 and 37 of the switch control unit 35 are turned off.
The control signal is output from the control signal output terminal 38 to the control signal input terminal 44 of the changeover switch 40, and the switch is switched to the output terminal 41 to transmit the received audio signal to the earphone 80.
Indicates the state of transmission.

The operation when using the earphone 80 is as follows. When the earphone 80 is not used, the cord 81 is wound by a winding spring at the center of the cord winding mechanism 20, and the cord 81 is wound until the earphone 80 is set on the earphone support 15. At the same time, the tip 80a of the earphone 80 is
Is pressed to turn on the switch control unit 35. Therefore, the changeover switch 40 is connected to the speaker 10, and the speaker 10 outputs sound.

Here, when listening to the sound with the earphone 80, the earphone 80 is taken out from the earphone support 15.
At this time, the spring 33 extends to separate the contact short-circuit plate 32 from the earphone sensing contact 31, and the switch control unit 35 is turned off. Therefore, the changeover switch 40 is connected to the earphone 80, and a sound is output from the earphone 80.

In this embodiment, when the earphone is stored, the speaker is automatically switched to the speaker. However, a manual switch may be provided instead of the switch 40. Further, a manual short-circuit switch may be provided in the switch control unit.

According to the technical idea of the present invention, it goes without saying that the present invention can be applied not only to the earphone but also to a bone conduction microphone earphone in which a speaker and a microphone are incorporated in the earpiece.

[0021]

The portable radio telephone having the winding cord type earphone of the present invention has the following effects. The earphone is detachably supported and stored on the side of the portable wireless telephone, and its cord is also wound up and stored in the telephone, so you can switch from the speaker to the earphone at any time and change the sound with the earphone Can be received. There is no need to worry about forgetting the earphone storage device, and the cord storage area can be rolled up inside the phone, making it easier to use.
