Abstract

PURPOSE:To easily adjust a sound volume by gripping a main body with a hand and increasing/decreasing a sound volume of a reception section with an outputted sensor signal. CONSTITUTION:A control circuit 114 receives quantized pressure information from an A/D converter 122 and controls an electronic volume 123 when a telephone set is gripped at a prescribed pressure for a prescribed time or longer, then a sound volume of a voice signal outputted from a reception section 102 is adjusted through an amplifier 121B. A pressure sensor 108 is provided to a part of the main body 100 gripped by a hand and when the main body 100 is gripped by a hand, the sensor 108 outputs a signal. Then the sound volume of the reception section 102 is increased/decreased and the sound volume is easily adjusted without removing the ear from the reception section 102 during talking.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handy type telephone having a main body such as a handset of a portable telephone or a cordless telephone, a receiver, and a transmitter.

[0002]

2. Description of the Related Art In a conventional hand-held telephone, the volume of the earpiece is usually adjusted by two touch switches or rotary knobs installed on the side of the telephone body to adjust the volume. It was increasing and decreasing. Alternatively, it may be performed by a switch arranged together with the dial switch of the main body.

Therefore, in the case of a handy type telephone, it is necessary to operate the earpiece away from the ear in order to hold the body of the telephone by hand and adjust the volume during a call. In addition, it was not easy to operate the earpiece without removing it from the ear, which required familiarization.

[0004]

Therefore, the present invention has been proposed in view of such a conventional situation, and anyone can easily adjust the volume of the earpiece without taking the earpiece away from the ear during a call. The purpose is to provide a handy type telephone that can be adjusted.

[0005]

DISCLOSURE OF THE INVENTION The present invention provides a handy-type telephone having a main body and a transmitter / receiver unit integrated with each other, such as a handset of a mobile phone or a cordless telephone. Attach a pressure sensor, touch switch, or pressure sensitive switch to one or both sides, one side or both sides of the part touched by the thumb, all of these parts,
A signal output by gripping with a hand or pressing with a finger detects the number of times of pressing, the time of pressing, the strength of pressing, or a plurality of states, and the state of the earpiece The feature is that the volume is increased or decreased.

[0006]

By constructing the handy type telephone in this way, anyone can easily adjust the volume of the earpiece during the call without removing the earpiece from the ear.

EXAMPLES Specific examples of the present invention will now be described with reference to the drawings, but it goes without saying that the present invention is not limited to these examples. FIG. 1 is an outline view showing a telephone according to the present invention. In FIG. 1, the present invention relates to a mobile phone, a cordless phone, a main body 100, and a transmitter / receiver 101.
It is about handy type telephones that are integrated. The transmission / reception unit 101 includes a reception unit 102 and a transmission unit 103.
Consists of. The earpiece 102 has a speaker that outputs voice from the other party, and the transmitter 103 has a microphone that inputs voice to the other party.

The telephone further includes a dial unit 104 for inputting a telephone number and the like, and an antenna 10 for outputting a radio carrier.
5, battery 106, and display 107. The feature of the present invention resides in that the pressure sensors 108A and 108B are built in the portions of the main body 100 that are held by the hands.

A circuit block diagram of the telephone of the present invention is shown in FIG. In FIG. 2, an antenna 10 is used to input and output a carrier between a master station in a mobile phone and a master station in a cordless phone.
5, the transmission / reception carrier is subjected to processing such as demodulation and decoding in the receiver 111 through the transmission / reception duplexer 110,
The transmitter 112 performs processing such as modulation and coding. Also,
The transmission / reception frequency is set by the synthesizer 113.

The control circuit 114 performs connection / maintenance / disconnection of communication with the master station or the master device and control inside the telephone. The transmitting / receiving unit 101 controls the volume of an audio signal output from the receiving unit (speaker) 102 and the audio signal input from the transmitting unit (microphone) 103, and performs encoding / decoding and compression / expansion processing depending on the system. ..

The number information input from the dial unit 104 is input by the control circuit 114, displayed on the display unit 107, and subjected to predetermined control. Pressure sensor 108A, B
The signal from is input to the control circuit 114, and the transmitting / receiving unit 10
By controlling 1, the volume of the receiving unit 102 is adjusted. As described above, the feature of the present invention is that the volume of the receiving unit 102 is adjusted by the signals from the pressure sensors 108A and 108B.

FIG. 3 shows a block diagram of the volume control circuit of the telephone of the present invention. In FIG. 3, the pressure sensors 108A, B
The pressure sensed in 1 is output as a signal, this signal is amplified by the amplifier 121A, and A / D converted by the AD converter 122 to be quantized. At this time, the sample clock is output from the control circuit 114 as variable in order to prevent malfunction.

In the control circuit 114, the AD converter 12
When the quantized pressure information is input from 2 and the telephone is held for a certain time or longer at a certain pressure or more, the electronic volume 123 is controlled and output from the receiving unit 102 via the amplifier 121B. Adjust the volume of the voice.

FIG. 4 shows a control flow chart of the telephone of the present invention. In FIG. 4, when it is detected from the quantized data from the pressure sensor that a certain pressure or more is applied, the time when the pressure is applied is observed. If the time is longer than a certain time, the number of times the state occurs within a certain time is measured as the number of clicks. Depending on the number of clicks, increase / decrease in volume is switched to adjust the volume output from the receiving unit 102.

Although the sensor has been described as an example of the pressure sensor, a switch, for example, a pressure sensitive switch or a touch switch is also included. Although the mounting position of the sensor is described as an example on both sides of the main body side, it may be on one side of the main body side. Further, the number of sensors may be one on one side, plural on one side, one on each side, and plural on both sides.

Although the example of the number of clicks applied has been described as the processing condition, the processing can be determined by the pressure value itself and the time during which the pressure is applied. The thresholds for processing such as pressure thresholds and time thresholds can be fixed values or can be specified by the user from the dial.

The volume increase / decrease value can be a fixed value, proportional to a pressure value, proportional to time, or the like. Further, the volume can be increased / decreased not only by the number of clicks but also by the click time.

[0018]

As is apparent from the above description, according to the present invention, in a handy type telephone having a main body, an earpiece, and a transmitter, the sensor is provided at a portion of the main body to be held by a hand. By increasing or decreasing the volume of the earpiece by the signal of the sensor output by grasping the main body with a hand, anyone can easily adjust the volume of the earpiece without taking the ear off the earpiece during a call. The effect is that it can be adjusted.
