Abstract

PURPOSE:To allow a charger to generate a call tone in a large tone volume when a mobile set is placed on the charger. CONSTITUTION:A call signal is received by a reception means 12 of a mobile set and a call tone signal generating means 42 outputs a call tone signal in an audible tone frequency in response to the call signal received by a reception means 12 and a lighting means 32 blinks synchronously with the call tone signal. The blink of the lighting means is received by a light receiving means and converted into an electric signal and outputted to the call tone signal generating means 42, which generates the call tone signal to sound a speaker 45.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a cordless telephone,
The present invention relates to a mobile wireless telephone using a rechargeable secondary battery such as a handheld cellular phone.

[0002]

2. Description of the Related Art As a recent trend, a wireless telephone having a receiving means such as a mobile device of a cordless telephone or a handheld cellular phone has been miniaturized, and even in a sounding section of a sounding device for notifying a user of an incoming call signal. It is no longer possible to have a space inside the cabinet that emits sound efficiently.

Further, since the device uses a battery, the electric power for driving the sounding body is also limited.

[0004]

Since the device is a portable device, as long as the user wears it and carries it with him, even if the volume for notifying the incoming signal is small, it is sufficient. When charging on the external battery to charge the built-in battery, it is highly possible that the user will be located far away from the location, so it is sufficient to use the incoming call signal sound from the inside of the mobile radio. There was a problem that it was not possible to produce various sounds.

The present invention has been made in view of the above-mentioned prior art. Means for issuing an incoming call signal from the inside of the mobile device to an external device when charging such a small mobile device, and inside the charger By having a means for detecting the signal and a means for converting the signal into acoustic light, etc., and outputting,
This makes it possible for the user to recognize the ringing tone at a sufficient level.

[0006]

In order to achieve this object, a wireless telephone according to the present invention comprises a mobile unit which is supplied with electric power from a rechargeable battery and a charger which charges a rechargeable battery of the mobile unit in the previous period. In the mobile device, receiving means for receiving a ringing signal, ringing tone signal generating means for generating a ringing signal of an audible frequency in response to the ringing signal output from the receiving means, and the ringing signal In the speaker, a speaker that generates a ringing tone signal output from the generating unit as a ringing tone, a light emitting unit that blinks in synchronization with the ringing tone signal, and the charger.
A light receiving means for receiving blinking of the light emitting means of the mobile unit and converting the light into an electric signal; a ringing tone signal generating means for generating a ringing tone signal in response to an electric signal output from the light receiving means; The speaker is configured to generate a ringing tone signal output from the tone signal generating means as a ringing tone.

[0007]

With this configuration, the ringing signal is received by the receiving means of the mobile unit, and in response to the ringing signal received by the receiving means, the ringing tone signal generating means outputs the ringing tone signal of the audible frequency and the light emitting means is activated. Flashes in synchronization with the ringing signal. The blinking of the light emitting means is received by the light receiving means of the charger, converted into an electric signal and output to the ringing tone signal generating means, and the ringing tone signal generating means generates the ringing tone signal and causes the speaker to ring.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an external view of a mobile device of a wireless telephone according to the present invention, FIG. 2 is an external view of a charger, and FIG. 3 is a block diagram of the mobile device and the charger. In FIG. 1, reference numeral 1 denotes an optical display, which is composed of LEDs. Reference numeral 2 is a sound hole for generating a ringing sound, 3 is a charging terminal, 4 is a charging terminal in FIG. 5, 5 is a hole for a light receiving portion, 6 is a volume control knob, and 7 is a sounding hole for generating a ringing sound. .. In FIG. 3, 11 is an antenna, 12 is a receiving means, 13 is a transmitting means, 14 and 15 are amplifying means, 16 is a speaker, 17 is a microphone, 18 is an amplifying means for ringing tone, and 19 is a ringing tone. Speaker, 22 is a diode,
23 is a battery, 24 is a control means, 32, 33, 34, 39
Is a resistor, 35 is a transistor, 36 is a constant current circuit, 37
Is a power supply circuit, 38 is a phototransistor, 40 is a filter, 41 is an analog switch, 42 is a ring tone generator, 4
3 is a power amplifier, 44 is a volume, and 45 is a speaker.

The operation of the mobile unit configured as above will be described below. First, when a calling signal is input, the mobile station sends this signal to the antenna 11 and the receiving means 12.
And outputs a calling signal to the control means 24. When the control means 24 determines that this signal is a ringing signal, it generates a ringing tone signal from the output terminal. The ringing tone signal is amplified by the amplifying means 18, and is generated as a ringing tone from the speaker 19 through the sound hole 2. Further, the control means 24 blinks the LED 1 in response to the incoming call signal.

Next, a case where the mobile device is charged by the charger will be described. When the mobile device is placed on the charger, the charging terminal 3 of the mobile device and the charging terminal 4 of the charger come into contact with each other, and the LED 1
And the hole 5 for the light receiving portion are aligned. The current supplied from the power supply circuit 37 of the charger passes through the constant current circuit 36, the charging terminal 4, the charging terminal 3, and the diode 22 to charge the battery 23.
Further, the transistor 35 in the charger is turned on and the analog switch 41 is also turned on.

When a calling signal is input in this state as described above, the LED 1 blinks in synchronization with the calling signal. On the other hand, the charger receives the change of the light in the phototransistor 38 through the hole 5 and changes it into an electric signal, and inputs it into the ringing tone signal generator 42 through the noise filter 40 and the analog switch 41. The ring tone signal generator 42 generates a ring tone signal in synchronization with the input signal. The output from the ringing tone signal generator 42 sounds the ringer speaker 45 through the volume 44. Analog switch 41
Is in the off state when there is no mobile unit, but this is to prevent the ringing tone signal generator 42 from malfunctioning due to external light.
