Abstract

A portable phone system includes a portable phone receiver and transmitter and an acoustic driving circuit coupled to a CPU. An acoustic processor is coupled to the acoustic driving circuit for processing input voice signals, along with a microphone and a speaker. A receiver and transmitter is coupled to the acoustic processor, and a headset unit comprising a microphone and an earphone may exchange voice signals with this receiver and transmitter to allow a user to use the portable phone system in a hands-free mode.

Description

PORTABLE PHONE ACOUSTIC CONTROL SYSTEM The invention relates to a portable phone acoustic control system.

Typical portable phone systems have been widely used and have to be controlled by a number of switch buttons. The user have to depress the switch buttons for controlling the phone system and have to hold the handset. However, it is dangerous while the user is driving. Many accidents occur when the user uses portable phone.

It is* accordingly an object of the present invention to provide a portable phone that may be operated without depressing any button and without holding the handset.

According to the present invention there is provided a portable phone system comprising: a central processing unit (CPU), a portable phone receiver and transmitter coupled to said central processing unit, an acoustic driving circuit coupled to said CPU, an acoustic processor coupled to said acoustic driving circuit for processing inlet voice, a first microphone and a speaker coupled to said acoustic processor for input and output voice, a first receiver and transmitter coupled to said acoustic processor for input and output voice, a second receiver and transmitter, and a second microphone and an earphone coupled to said second receiver and transmitter for transmitting and receiving a voice to said first receiver and transmitter via said second receiver and transmitter and for allowing user to use said portable phone system without using his hand.

An acoustic memory may be coupled to said acoustic processor for storing user's voice and for preventing unauthorized person from using said phone system.

At least one button is coupled to said acoustic driving circuit for switching between said first receiver and transmitter and said speaker.

An acoustic random access memory is coupled to said CPU for storing instructions.

A telephone control circuit is coupled to said CPU for coupling said CPU to a telephone line, and a third receiver and transmitter coupled to said CPU for receiving and transmitting a call.

A memory may store phone numbers and may allow said phone system to dial selected phone number.

A secret code setting circuit may be coupled to said CPU for allowing the user to enter secret code and for preventing unauthorized person from using said phone system.

In the drawing: FIG. 1 is a block diagram of a portable phone acoustic control system.

As shown in the drawing, a portable phone system comprises a central processing unit (CPU) 10, and a portable phone receiver and transmitter (handset) 12 is coupled to the CPU 10 via an interface 11 which is coupled to a direct current or alternate current electric power supply 15 or to the electric system of the vehicle via a stabilizer 14. Two memories 16, 17, such as acoustic random access memories (RAM), and a displayer 19 and a secret code setting circuit 19 are coupled to the CPU 10. The memory 16 may store phone numbers for allowing the phone system to dial stored phone numbers. The memory 17 may store acoustic instructions, such as "dial number ...", "switch to earphones', etc. The displayer 18 may show the status and/or instructions and/or phone numbers etc. The secret code may be entered into the CPU via the setting circuit 19 for preventing unauthorized person from using the phone system. A telephone control circuit 20 may couple the CPU 10 to the family telephone line 21 and/or to the receiver and transmitter 22, such as beeper, recorder etc.

An acoustic processor 31 is coupled to the CPU 10 via an acoustic driving circuit 30 for processing inlet voice. A receiver and transmitter 32 and a microphone 33 and a speaker 34 are coupled to the acoustic processor 31 for receiving and/or transmitting voices.

One or more press buttons 36 may switch between the receiver and transmitter 32 and the microphone 33 and the speaker 34. An acoustic memory 35 may store the voices of the users and is coupled to the acoustic processor 31 for recognizing the voices of the users and for preventing unauthorized person to use the phone system. Another microphone 38 is coupled to another receiver and transmitter 37 which may transmit a sound or voice to the receiver and transmitter 32 and which includes an earphone 39 for allowing the user to use the phone system without using his hands. The user may also contrbl the phone system via the microphone 33 directly. The voice may be output via the speaker 34 or to the earphone 39 via the receiver and transmitter 37, 32. When the output voice may not be heard by the others, the user may switch to the earphone 39 for allowing only the user to hear the sound. The receiver and transmitter 37 may be energized by battery 40.

In operation, when the user is speaking, the acoustic processor 31 may identify the voice by comparing that stored in the acoustic memory 35 and may couple to the CPU 10 for storing phone numbers in the memory 16, for storing acoustic instructions in the memory 17, for setting secret code 19 and for receiving the telephone line 21, or for transferring the telephone line to another receiver and transmitter 22, such as beeper or recorder. The user may use his voice to couple the phone line to the speaker 34 or the earphone 39 and to receive the call and to dial the pre-stored phone numbers and to control the phone system by the instructions stored in the memory 17. The most important thing is that the user may control the phone system via the microphones 33, 38 without using the handset 12, such that the user may concentrate on driving and such that accidents may be greatly decreased. The acoustic processor 31 may recognize the users' voices. In addition, the entered secret code (19) may prevent the other people from using the phone.
