FR2768285A1 - Telephone ringing signal control circuit with facility for personalization - Google Patents

Abstract

the telephone includes an analogue to digital converter enabling conversion of the received microphone signal to digital format in order to be memorized. The system includes a microphone transforming a received signal into an analogue electrical signal, and a converter changing this signal into digital format. A memory is able to store the resulting digital signal. When an incoming call is detected by the telephone circuit, the circuit uses the stored digital signal which is converted back into analogue format, amplified and applied to a loudspeaker. The resulting sound is used as the telephone ringing signal. The microphone used in the circuit may be the normal microphone forming part of the telephone handset.

Description

 The present invention relates to a telephone ringing characterized by the fact that the sound emitted in the event of a call comes from a memory circuit where it has been previously recorded in digital form.

 Telephone ringtones are traditionally analog and make unpleasant sounds.

 The device according to the invention replaces traditional ring tones. according to a first characteristic, it indeed comprises a memory circuit on which a sound is recorded in a digital format, according to a second characteristic a circuit converting this digital recording into an analog signal, according to a third characteristic a device amplifying this analog signal and according to a fourth characteristic in a loudspeaker transforming this amplified analog signal into sound.

According to particular embodiments:
a) Several different sounds can be recorded in the factory in the ct memory
add a command to the electronic components of the telephone device
allowing the user to choose which of the sounds in memory will be
made when a call arrives.
b) It will be possible to add to the electronic components of the telephone apparatus a
circuit randomly choosing one of the sounds in
memory. The user can optionally using commands activate and
deactivate this operating mode and choose which sounds may or may not
cannot be selected by the telephone device.
c) In the case of a telephone set provided on the one hand with a system
allowing to know the phone number of the caller and on the other hand
a system allowing the user to store several numbers in memory
phone, we can add commands coupled to a circuit
electronic allowing to associate a sound to each telephone number
remembered.
d) It will be possible to add to the electronic components of the telephone apparatus a
microphone and analog / digital converter allowing the user
to record one or more sounds in memory itself.

 The accompanying drawing illustrates an embodiment of the invention, in which the loudspeaker 1 also serves as a microphone. Two doors and 2 and 3 controlled by the push button 4 and the sound signal from the telephone 5 control the write or read function of the memory 6 and the state of the analog switches 7,8 and digital 9,10.

 When the push button 4 and the ring signal 5 are inactive, or when both are active, none of the two doors 2 and 3 deliver a signal, no memory function is then activated, and the four switches 7, 8,9,10 are in the open state. Therefore, nothing happens.

 If button 4 is activated and if signal 5 is inactive, door 2 does not deliver a signal, and therefore the memory read command is deactivated and the 8 ct switches 10 are open, while door 3 delivers a signal, thus commanding the closing of the switches 7 and 9 as well as the command to write the memory. The sound signals picked up by the microphone 1 are then amplified by the amplifier 11, converted into digital information by the analog / digital converter 13 and stored by the memory 6. The button 4 thus triggered the recording of a sound.

 If button 4 is not activated and If signal 5 is active, door 3 does not deliver a signal and therefore the memory write command is deactivated and switches 7 and 9 are open, while the door 2 delivers a signal, thus commanding the closing of switches 8 and 10 as well as the command to read the memory. I, a memory 6 then restores the digital signal which is recorded there. This signal is transformed into an analog signal by the digital / analog converter 14, then amplified by the 12 ct amplifier reproduced by the loudspeaker 1. The ring signal therefore triggers the restitution of the sound recorded in the memory.

 The device according to the invention is particularly intended for telephone devices.

 N.B. 1) You can use the analog amplifier and the speaker already present in some telephone devices to amplify the analog signal at the output of the digital / analog converter and transform it into sound.

 2) In the case of a digital cellular telephone device, the analog / digital and digital / analog converters already present in these devices can be used.

 3) In the case of a telephone device comprising an automatic digital answering machine, analog / digital and digital / analog converters and the memory circuits already present in these devices may be used.

 4) In the case described in d), the microphone of the telephone handset can be used.
