Description

Mobile communication device with wireless earphones {Apparatus for mobile communication with wireless earphone}

The present invention relates to a mobile communication device having a wireless earphone, and more particularly, the earphone can be wirelessly handled and used conveniently during driving, walking, and meetings, and can be used without invasion of privacy, and additional services provided by a communication service company are provided. The present invention relates to a mobile communication device having a wireless earphone which is secretly provided and prevents unnecessary communication with a counterpart caller.

Mobile cordless telephones are generally intended for personal mobile communication services, and their use is exploding because users can conveniently and quickly deliver messages to users of other landline or mobile cordless telephones regardless of location. To make a call using a mobile cordless phone while the user is moving through a vehicle, a call is made using a hands free device. When using such a vehicle hands free device, the voice of the other party's voice is transmitted through a speaker. Since the confidentiality of the call is not guaranteed, conventionally, the apparatus shown in FIG. 1 is used to improve this.

1 is a block diagram showing a hands-free device for a mobile radio telephone according to the prior art, and FIG. 2 is a perspective view for implementing the hands-free device of the prior art shown in FIG.

1 and 2 together, the connection jack 24a connected to the wireless telephone connection unit 24 of the hands-free kit 20 is connected to the ear microphone connection portion 11 of the mobile radio telephone 10. The ear microphone connection part 26 of the hands free kit 20 connects the ear microphone 30.

At this time, the ear microphone 30 is composed of the earphone 31 and the microphone 32, when the charging of the mobile radio telephone 10, the mobile phone 10 is mounted on the hands free kit 20, the cigar jack ( The charging system 29 is connected to the charging system 29.

In this way, when a call is received while driving while the ear microphone connection portion 11 of the mobile wireless telephone 10 is connected to the hands-free kit 20, the driver and the occupant are set / released to a call provided in the ear microphone 30. Press 40 or operate the mobile radio telephone 10 to make a call while the call path is set.

When the caller wishes to make a secret call in the above-described call process, when the switch 27 provided in the hands free kit 20 is operated, the circuit between the radio telephone connection unit 24 and the speaker 22 is cut off, and the radio telephone connection unit Since the circuit between the 24 and the ear microphone connection unit 26 is connected and the received voice signal R is output only through the earphone 31, the confidentiality of the call is guaranteed, and the LED (Light Emitting Diode) 25 is emitted. It indicates that the received voice signal R is output to the earphone 31.

If it is irrelevant to the contents of the call, if the switch 27 is operated again, the amplifier 21 and the speaker driver 23 between the wireless telephone connection unit 24 and the speaker 22 operate to receive the received voice signal R. ) Is output through the speaker 22 and sent to the driver or the passenger.

Meanwhile, the voice signal S to be transmitted is input to the microphone 32 and transmitted to the wireless telephone connection unit 24 through the ear microphone connection unit 26, and the blocking circuit 28 is output through the speaker 22. It is a blocking circuit that prevents the received voice signal R from being transmitted to the other party.

By the way, according to the conventional hand-free device for a mobile radio telephone, the following problems occur.

The prior art allows the driver to make a hand-free call while driving, but the earphone is connected by wire, which makes it convenient to use during driving, walking and meetings, and cannot be used without invasion of privacy. You will not be able to receive music, securities information and other value-added services provided, and the other party will be able to hear the caller's voice.

Accordingly, the present invention is to solve such a problem, and an object of the present invention is to enable the use of the mobile wireless telephone in various spaces without being limited to the vehicle.

Another object of the present invention is to allow music, securities information, and other additional services provided by a mobile wireless telephone to be received without invading privacy.

Another object of the present invention is to attach a high-sensitivity microphone and call key to a mobile wireless phone to perform a smooth call without crosstalk and noise even in a noisy area.

Another object of the present invention is to prevent the called party from sending the called party's voice to the other party while the other party is on the phone.
