Abstract

A beeper includes a micro processor unit 4 controlled by a receiver signal to drive a motor 6 or a speaker 5 causing it to vibrate or make sound so as to inform the user of the receiving of a message, to drive a message display 7, and to drive a speech IC 8 causing it to speak out the content of the message through a piezoelectric buzzer 9. The speech IC 8 is disabled 83 in response to low power or manual operation. <IMAGE>

Description

CIRCUIT DEVICE FOR BEEPERS The present invention relates to a speech IC circuit device for a beeper which comprises a speech IC controlled by the micro processor unit of the beeper to tell the user the content of the received message by synthesized speech.

A regular beeper generally comprises a receiver controlled to receive carrier signals from a transmitter, a decoder controlled to decode the signals been received, and a micro processor unit controlled to drive a motor-driven vibrator causing it to produce vibrating waves or to drive a speaker causing it to make sound so as to inform the user the receiving of a message. While turning on the motor-driven vibrator or the speaker, the micro processor unit gives a data to a display through parallel output terminals thereof for showing the code of the signal been received. It is very dangerous to watch the display while the user of the beeper is driving a motor vehicle or doing a risk job.

The present invention gives a solution to eliminate the aforesaid problem. It is therefore the main object of the present invention to provide a speech IC circuit device for a beeper which tells the user the content of the message been received by synthesized speech. To achieve this object and according to the preferred embodiment of the present invention, the speech IC circuit device comprises a receiver to receive carrier signals, a decoder to decode the signals received by the receiver, a micro processor unit to process the signals transmitted from the decoder and store them in the memory thereof, a motor and a speaker driven by the micro processor unit to inform the user the receiving of a message by sound or vibrating waves, a display controlled by the micro processor unit to show the content of the message been received, and a speech IC controlled by the micro processor unit to speak out the content of the message been received. The speech IC gives a busy signal to the micro processor unit while speaking. The micro processor unit gives an enable signal to the speech IC causing it to do work, or gives a disable signal to the speech IC causing it to stop from working upon the detection of a manual operation or low power operation mode.

Fig. 1 is a system block diagram of a speech IC circuit device according to the present invention; Fig. 2 is a circuit block diagram of the speech IC circuit device; and Fig. 3 is a flow chart showing the operation procedure of the speech IC circuit device.

Referring to Figs. 1 and 2, a speech IC circuit device in accordance with the present invention comprises a receiver 2 having a receiving antenna 1 to receive carrier signals from a transmitter. The signal received by the receiver 2 is then sent to a decoder 3 which decodes the signal according to standard beeper telecommunication agreement and then sends a corresponding signal to a micro processor unit 4.

Upon receipt of the signal from the decoder 3, the microprocessor unit 4 drives a speaker 5 to give sound or a motor 6 to make vibration so as to inform the user of the receipt of a message. The received signal is simultaneously recorded in the memory of the micro processor unit 4. At the same time, the micro processor unit 4 sends the character data being received by the beeper to a display 7 through parallel output terminals for display, and drives a speech IC 8 to retrieve speech data segments in proper order according to the character data being received. The retrieved speech data segments are sent out through a piezoelectric buzzer 9. While sending out the speech, the speech IC 8 sends a busy signal through a busy line 81 thereof to the micro processor unit 4 informing it to stop from sending signals.After one speech data segment has been sent out, the busy signal is stopped, and the micro processor unit 4 sends a next data to the speech IC 8. This procedure is repeated until all received signals have been sent out. Further, the micro processor unit 4 has an enable line 82 and a disable line 83 connected to the speech IC 8. Under normal operation, the micro processor unit 4 gives an enable signal to the speech IC 8. As the micro processor unit 4 detects a manual operation or low power operation mode, it outputs a disable signal to the speed IC 8 causing it to stop from working.

Referring to Fig. 3, when a carrier signal from the exchange center A is received and recognized through decoding B, a corresponding signal is sent to the micro processor unit C causing it to turn on the motor or the speaker so that the motor vibrates or the speaker beeps D, and simultaneously the message is shown through.the display E and speak out by the speech IC.

While only an embodiment of the present invention has been shown and described, it will be understood that various modifications and changes could be made without departing from the spirit and scope of the invention.
