An identification code decoder 25; And gate AD outputting a mute control signal MCS to cancel the muting operation of the mute control unit 23 when a signal of a predetermined level is output from both the carrier detector 24 and the identification code decoder 25. Wow; An amplifier (AMP) for amplifying a voice signal output without being muted by the muting control unit 23 to a predetermined level and outputting the same to the speaker SP; With reference to FIGS. 4 and 5 attached to the operation and effect of the present invention configured as a microcomputer 26 that collectively controls the operation of each of the receiving unit is as follows.

First, an e-mail transmission process will be described with reference to FIGS. 2 and 4.

After the system is initialized, the e-mail server 11 checks whether the e-mail has arrived to the user, and if it does not arrive, checks whether the e-mail arrives continuously. If the e-mail arrives, the e-mail server 11 reads and stores the user account. (ST1-ST3)

Thereafter, it is checked whether the user account is set as an account for broadcasting and terminates as it is not set for broadcasting. However, if it is set as an account for broadcasting, the received e-mail is output to the voice synthesizing unit 12 and the identification code encoder 14, respectively. (ST4)

Therefore, the voice synthesizer 12 converts the e-mail output from the e-mail server 11 into a voice signal and outputs the voice signal. The ID code encoder 14 compares a user account to find a broadcast ID code. After that, it is encoded in a predetermined format. As an example of encoding the identification code (ID), techniques such as complex frequency (DTMF) can be used. (ST5, ST6)

At this time, the voice signal output from the voice synthesizer 12 is converted into an analog voice signal through the D / A converter 13 and provided to one input of the mixer 15. Therefore, the mixer 15 mixes and outputs the audio signal output from the D / A converter 13 and the identification code ID coded and output from the identification code encoder 14. It is transmitted to the air through the broadcasting device 16 and the transmitting antenna ANT1. (ST7.ST8)

Meanwhile, a process in which the subscriber receives an e-mail transmitted as a voice signal through the above process will be described with reference to FIGS. 3 and 5.

In the initialization state, the mute control unit 23 is muted and no signal is emitted from the speaker SP since the received signal is muted by the mute control unit 23. (SR1)

A signal transmitted through the transmitting antenna ANT1, that is, a voice email signal carried on a high frequency signal, is received through the receiving antenna ANT2 and input to the station and detector 21. Therefore, the tuning and detecting unit 21 performs the tuning and detecting function on the input high frequency signal and outputs a voice email signal therefrom.

The voice e-mail signal output from the station and detector 21 is transmitted to the tone control unit 22, the volume and tone are adjusted to a preset pattern, and then transmitted to the mute control unit 23. At this time, the mute control signal MCS ) Is supplied low, it is not transferred to the next amplifier (AMP) and muted to ground.

At this time, the carrier detector 24 checks whether or not the carrier is output from the channel selection and detector 21, and if not detected, continues the detection operation, and if detected, outputs a high signal of a predetermined level. (SR2) In addition, the identification code decoder 25 decodes the identification code (ID) output in a predetermined form (eg, DTMF) from the station and detector 21 and compares it with a preset identification code of the same to each other. Outputs a predetermined level of signal (SR3, SR4).

Therefore, the carrier is detected by the carrier detector 24, and a high signal of a predetermined level is output therefrom, and the identification code ID of the subscriber is detected by the identification code decoder 25, and a high signal of a predetermined level is detected therefrom. Is outputted, the high signal is supplied to both input terminals of the AND gate AD. At this time, the mute control signal MCS is output high at the AND gate AD so that the mute operation of the mute controller 23 is performed. Release (SR5)

As a result, the voice email signal output from the tone control unit 22 is transmitted to the amplifier AMP through the mute control unit 23, amplified to a predetermined level, and then transferred to the speaker SP. It is possible to recognize the contents of the voice e-mail uttered at the), and if necessary, additionally connects a voice signal detection device and a recording device to the output of the amplifier (AMP) and records the e-mail when the voice e-mail is output. When necessary, the contents of the received voice mail can be confirmed. (SR6)

However, when the carrier is not detected at the carrier detector 24 or the identification code ID of the subscriber is not detected at the identification code decoder 25, the mute control signal MCS is low at the AND gate AD. As a result, the voice e-mail received from the mute control unit 23, that is, the e-mail not related to the subscriber, is muted.

As described in detail above, the present invention converts the e-mail output from the e-mail server into a voice signal, and wirelessly transmits the voice signal to the subscriber through the transmission and reception system, the subscriber of the account registered using the identification code By selectively receiving only your own e-mail, you can deliver your e-mail regardless of time or place.
