And a signal processing unit for processing a signal so that voice transmission / reception with the speaker and the microphone is performed in a wireless manner, and a necklace for allowing the user to hang the phone around the neck.

The wireless telephone may further include a jack for connecting one of the earphone and the headphone so that only the user can hear the other party's voice.

Hereinafter, with reference to the accompanying drawings, the configuration and operation according to a preferred embodiment of the present invention.

1 is a view showing the shape of a landline phone in a general wired / wireless combined phone, Figure 2 is a view showing a wireless phone in the shape of an earphone as an embodiment of a wireless phone according to the present invention, Figure 3 according to the present invention As another embodiment of the wireless telephone is a view showing a shape designed to talk on the neck of the wireless telephone, Figure 4 is a block diagram showing the internal configuration of a wireless telephone according to the present invention.

The landline telephone 101 according to the present invention has the same shape as the landline telephone of a general wired and wireless combined telephone as shown in FIG. 1.

The wireless telephone according to the present invention is intended to have only the minimum necessary functions such as incoming and outgoing calls in existing wireless phones capable of incoming, outgoing and calling. For this reason, it is desirable to minimize the volume by removing other configurations, for example, additional functions such as extension calls, keypads, and the like.

Therefore, as shown in FIG. 2, the wireless telephone includes a call button 201 for receiving a telephone call when the telephone comes in, a battery lead-in unit 202 for mounting a small battery such as a mercury battery, and the wireless telephone. A power switch 203 which is a means for turning on / off the power of the antenna, an antenna 204 for transmitting / receiving radio waves, and an earring 205 that can be attached to and detached from the ear to simplify the portable telephone. Speaker 206 for outputting voice and telephone ring, microphone 207 for receiving voice, and signal processing unit 400 for processing the wired telephone and voice transmission / reception in a wireless manner. It is composed of

In addition, although not shown, it is also possible to configure a headset-type wireless telephone by applying the configuration of the wireless telephone according to the present invention.

As another embodiment according to the present invention, the wireless telephone is configured to reduce the volume by minimizing the configuration such that only the incoming and the call can be made, as shown in FIG. As described above, a call button 301 for answering a call when a call comes in, a battery lead-in part 302 into which a battery enters, a power switch 303 used as a means for turning on / off the power of the cordless phone, radio waves Antenna 304 for transmitting / receiving, a necklace 305 for hanging the user's neck to simplify carrying the wireless phone, a speaker 306 for outputting the voice and call of the other party, a microphone for receiving voice 307, a jack 308 for connecting earphones, general headphones or bone conduction headphones, a signal processing signal to make a wired telephone and voice transmission / reception in a wireless manner Consists of a processing unit (see 400, Fig. 4 is an internal circuit configuration required).

At this time, the signal processing unit 400 is applicable to the two embodiments of the present invention shown in Figs. 2 and 3 in common, as shown in Fig. 4, a transmission for transmitting and receiving a wired telephone and radio waves A receiver 406, a modulator / demodulator 407 for modulating and demodulating the radio wave, and a voice signal received through a microphone to the modulator / demodulator 407, and outputting the modulator / demodulator 407 The transmitter / receiver circuit 409 for transmitting the signal to the speaker, the antennas 204 and 304 for transmitting / receiving radio frequency, the transmitter / receiver 406, the modulator / demodulator 407, and the transmit / receive circuit 409 It consists of a control unit 408 for the following. The transmission / reception circuit 409 is connected to a speaker, a microphone, and a call button.

As such, the signal processor 400 is an application of a signal processor used in a general telephone, and thus a detailed description thereof will be omitted.

Referring to the operation of the wired / wireless telephone according to the present invention configured as described above in detail.

When a call comes from the outside through the trunk line to the landline telephone 101, a telephone ring rings at the wired telephone 101 and speakers 206 and 306 of the wireless telephone. At this time, if the user is near the landline telephone 101, the handset can be picked up from the landline telephone.
