The present invention relates to a device for receiving and transmitting a bracelet-type radiotelephone in which reception and transmission are made by drawing or inserting an antenna of a wrist-worn radiotelephone and a control method thereof.

In general, wireless phones (wireless phones) are wire-free, made of a small size is easy to carry and are widely used as an advantage that can be called anywhere, anytime.

However, the cordless phone has been manufactured in a small size, making it easy to carry, but the risk of loss due to carelessness is highly diversified to be detachably portable to the body so as not to lose the cordless phone. For example, bracelet-type cordless phones have been developed. The bracelet-type cordless phone is designed to be worn on a wrist, such as a watch, and includes a watch and a calling function (aka beep) as well as a phone function. However, because the bracelet-type cordless phone must be worn on the wrist, the volume and weight of the bracelet-type cordless phone are smaller than those of ordinary cordless phones, so the dial buttons and various functional buttons are also very small in a narrow space. Therefore, it is desirable to operate the operation of various dial buttons and various function buttons to a minimum.

For reference, the process of deterioration for reception and transmission of a general wireless telephone is as follows.

In the case of reception, when a ringing tone is generated, a call is made by opening an outgoing communication board covering the reception button or the dial button after drawing the antenna to improve the call sensitivity. In case of calling, turn on the power switch (Power s / w), draw out the antenna, enter the desired number and press the send button (Send s / w) to talk to the other party.

As described above, in the case of the reception and transmission of the conventional radiotelephone, the inconvenience of having to operate various functional buttons sequentially is generated. In particular, in the case of an outgoing call, if the receiver is absent or not connected to the receiver, the call is attempted several times, which is a hassle of repeating the outgoing operation as described above.

Employing such a cumbersome reception and transmission function in a wrist wearable wireless telephone has a very cumbersome and inconvenient problem of operating various functional buttons installed in a limited range of the wrist as described above.

In addition, the main problem is that the conventional wrist wearable wireless phone has to speak in close proximity so that the speaker's voice is transmitted to the microphone built into the wireless telephone during the call, and wear the wrist to listen to the other party's voice from the speaker Because the radio cordless phone should be close to the ear, it is inconvenient to talk with the mouth and ear while changing the mouth and ears of the cordless phone worn on the wrist when talking and listening. In addition, when a lot of noise occurs in the call area, there is a problem that the call is difficult due to the noise, and there is a problem that personal privacy is exposed by leaking the call contents to others in the call area.

The present invention has been invented to solve the problems caused by the wireless telephone to be worn on the wrist as described above.

An object of the present invention is to make the phone body to improve the listening feeling when making a call in a noisy place and at the same time not to disclose the contents of the individual call to others in the call area when making a call through the wrist worn wireless telephone. To provide a receiving and transmitting apparatus having a receiver that can be placed in the ear to be fitted to the finger at the end of the antenna drawn from the.

If described in detail the working example and the working effect on the receiving and transmitting device of the wearable wireless telephone according to the present invention as described above.

First, the functional characteristics performed by the main circuit, that is, the microcomputer, according to the drawing and receiving operation of the antenna according to the present invention will be described with reference to FIGS. 7 and 8.

A block diagram for performing a circuit operation in accordance with antenna drawing and receiving is shown in FIG.

Referring to FIG. 7, a keyboard 100 (function button) having a plurality of keys for performing an operation according to a dicing or mode is connected to input a signal to the microcomputer 101, and the microcomputer 101 is provided. ) Is connected to the signal processing processor 102 to mutually interface information about a control signal and a signal processing state for operation control.

The signal processing processor 102 includes a receiver 103 for tuning, amplifying and applying a signal received through the antenna 3, a transmitter 104 for adjusting and outputting a signal to be transmitted by air over a specific frequency, and It is connected to a handset 20 for converting and outputting a signal to be received into an audible frequency range that can be heard by the user, and a handset 5 for converting a user's speech into a signal that can be recognized by the signal processing processor 102. .

And, the receiving unit 103 is connected to apply a signal that can recognize that the signal is received to the ringing unit 105 when a signal of a specific telephone number propagated in the air, ringing unit 105 is ringing operation And outputs a signal indicating that the signal is received by the microcomputer 101 and a ringing control signal can be input from the microcomputer 101.

In addition, the switch 106 is configured to perform a switching operation according to the antenna withdrawal and storage state according to the present invention. The switch 106 encodes the above-described micro switch, wherein the switch is connected such that the power supply voltage Vcc is applied to the terminal a through the resistor R, and the terminal b is connected to the microcomputer 101. Terminal c is grounded.

That is, the switch 106 has a structure that is switched according to the withdrawal and storage state of the antenna as can be seen in the above-described component. When the antenna is pulled out, the switch 106 is turned on, and when the antenna is stored, the switch 106 is turned off. The turn-on state of the switch 106 is a state in which the terminal a and the terminal b become conductive internally to apply a high level electrical signal to the terminal connected to the microcomputer 101, and the turn-off state of the switch 106 is internally Terminal b and terminal c are in a conductive state.

Operation according to the reception and transmission control method by the antenna according to the present invention configured as shown in FIG. 7 will be described in detail with reference to FIG.

When the portable telephone is not in the call mode, the portable telephone is in a standby state, that is, a state for performing a reception or origination operation. When the user draws an antenna for a call in the standby state or a corresponding signal propagated in the air is received and the user draws the antenna, the standby state is switched to the call mode by the control operation of the microcomputer 101. That is, the antenna is stored in the standby state.

In the call mode, a signal of the corresponding telephone number through which radio waves are received by the user is received, the antenna 3 is drawn out, and the signal received from the receiver 103 is controlled by the signal processor 102 of the microcomputer 101. Through the predetermined signal processing by the audible frequency signal to the handset 20 and at the same time the voice signal to the talker 5 by the microcomputer 101 to control the signal processing processor 102 through the predetermined signal processing process After the air propagation through the transmission unit 104, the user presses the desired number to call the keyboard 100, the corresponding signal is coded in the microcomputer 101, the signal processing processor 102 and the transmission unit The signal received through the receiver 103 is transmitted to the talker 5 at the same time as the audible frequency signal is received by the receiver 20 in the same manner as the reception operation with the other party after being transmitted through the receiver 104. Speech sound is transmitted through the transmitter 104.

In order to perform the above-described operation, the microcomputer 101 checks whether the received signal is input through the receiving unit 103 in step S4 while performing the standby state in step S2.

If it is determined in step S4 that there is no reception signal (N), the microcomputer 101 performs step S6 to check the current state of the switch 106. This is because when the user wants to perform a send operation for transmitting, i.e., operate a specific number key to attempt a call with the other party, the user must pull out the stored antenna 3 in the standby state. This is because the state of 106 is switched to the on state. That is, when the state of the switch 106 is turned on in the step S8 without the reception signal (Y), the microcomputer 101 performs the call mode described above by performing the step S10, and the step S8. If the state of the switch is not in the ON state (N), the step (S2) is performed again to maintain the standby state and repeat the above-described operation.

In step S10, the call mode is performed, and the microcomputer 101 checks the state of the switch 106 as an electrical signal level input to the terminal connected to the switch 106 (S12). This is because the switch 106 is switched from the current turn-on state to the turn-off state in accordance with the reception of the antenna because the user must store the antenna when the user wants to end the call.

After confirming the switch state in step S12, the microcomputer 101 performs the call mode again by performing step S10 again if the state of the current switch 106 identified in step S14 is ON (N). If the current state of the switch 106 is OFF (Y), the process returns to step S2 to maintain the standby state.

On the other hand, when the microcomputer 101 receives a specific signal of the corresponding telephone number to the receiving unit 103 in step S4 (Y), the receiving unit 103 receives a ringing unit to recognize the user that the radio propagated telephone signal is received. A predetermined signal is output to 105 to perform a ringing operation.

Accordingly, the ringing unit 105 performs a ringing operation and applies a predetermined signal to the microcomputer 101 indicating that the ringing is in progress. The microcomputer 101 recognizes the ringing in step S16 as a signal applied from the ringing unit 105 and checks the state of the switch 106 connected to the antenna by performing step S18.

The microcomputer 101 determines the state of the current switch identified in step S16 in step S18, and if the state of the current switch 106 is off (N), continues to step S16, and the current switch If the state of the 106 is the ON state (Y), the step S22 is performed to block the ringing, and then the step S10 of performing the aforementioned call mode is performed.

In the above, the circuit function and characteristics of the wrist wearable wireless telephone can be known through the antenna, and the operation examples and the effect according to the structural configuration will be described in consideration of this.

First, when the case is to be received through the wrist-worn wireless telephone, if the call is generated in the main body 10, the receiver grasps the head (3a) of the antenna 3, the antenna 3 from the main body 10 Withdrawal toward the finger opens the case 21 of the handset 20 and fixes it so that the tip of the finger is covered as shown in FIG. In this case, the inner surface of the case 21 is tightly fixed to the end of the finger by the coil spring 24. The wire 3b inserted into the main body is drawn out to the outside while sliding by the roller 6 while the antenna 3 is drawn out from the main body 10. The wire 3b is integrated into a predetermined area of the outer ear 3b. The fixed dog 8 presses the transfer section 9 so that the transfer section 9 presses the actuator 11a of the micro switch 11. Therefore, the actuator 11a is pressed by the transfer section 9 to electrically connect the contacts of the male position 11 so that the microcomputer 101 is switched to the reception mode.

The wire 3b is drawn out by the case 21 of the earpiece 20 coupled to the tip of the finger, although a predetermined elastic force acting to be inserted into the main body 10 by the spiral spring 7 acts even though it is drawn out to the outside. Stays in the state.

Further, the conveyance section 9 is a projection 9d of the leaf spring 9c on the groove 9b in which the circumferential surface of the rotor 9a is formed so as to be maintained in the pressurized state of the actuator 11a. It will be grounded.

When the micro switch 11 is switched by the transfer period 9, the piezo speaker 22 of the handset 20 outputs a voice signal of the other party received from the microcomputer 101 to make a call.

When the reception call is completed as described above, the gripper 21 of the handset 20 is detached from the finger to insert the antenna wire into the main body by the spiral spring 7. In this case, the dog 8 coupled on the wire 3b also transfers the transfer section 9 to the initial position in the process of being homed, thereby returning the actuator 11a of the micro switch 11 to the initial position.

When the actuator 11a is returned to its original position, the micro switch is switched to a reception standby mode function by switching a contact electrically connected to the microcomputer 101.

On the other hand, when calling through a wrist-worn wireless telephone, first input a desired telephone number through the dial button 1 shown in FIG. 1, and then withdraw the antenna 3 as described above. The case 21 of the user 20 is coupled to a specific finger of the user, and the receiver 20 is brought into close proximity to the user's ear hole or ear wheel as shown in FIG. 6 with the receiver 20 coupled to the finger. On the ear side, the talker 5 is placed naturally in the mouth to talk.

This call method is made in the same motion at the time of reception and transmission.

As described above, the wearable wireless telephone according to the present invention receives and transmits the antenna by drawing the antenna, so that unnecessary unnecessary button manipulation is not required and the call is interrupted by inserting the antenna. As it is switched to the state, it is effective not only to install unnecessary button function in the limited area of the cordless phone worn on the wrist, but also when the handset is in close contact with or close to the ear and mouth, It has the effect of overcoming the problem of exposing an individual's privacy to a person.

In the present specification, the receiving and transmitting device of the wrist-worn wireless telephone and the control method thereof are described for exemplary purposes only, and the switch function for circuit-controlling various functions in the extraction and insertion process of the antenna is changed or the handset and the handset.
