Description

The present invention relates to a hands-free mobile telephone with voice recognition at a decoiler.

Currently, cell phones are held in the hand. They require frequent handling and can be stolen or lost. They are unsuitable for children. Radiant emission can be harmful to the brain. Connection capabilities to other peripheral devices are reduced.

The present invention overcomes these drawbacks by presenting a new way of wearing and using it. We know US patent 44121 on a "stereo listening system to be worn ..." but it does not include radio transmission means. We also know the patent WO 98I0723 of radio transceiver but it has a complicated configuration with distribution of the elements on two shoulders, usable by being sewn on a jacket.

mobile phone according to the present invention comprises - at least one earpiece applying to the ear, - at least one microphone, near the mouth, - at least one transmitting and / or receiving antenna, - an electronic signal processing circuit from the microphone to the transmitting antenna, - an electronic circuit for processing the signal from the receiving antenna to the earpiece, - an electrical cord connected to the earpiece and / or microphone on the one hand, and on the other hand connected to one or both of said electronic signal processing circuits, - an unwinder of said cord with return spring, - an electronic circuit for controlling peripheral devices and said electronic signal processing circuits, - an electronic voice recognition circuit for telephone dialing, - an electrical power source coupled with the various preceding elements.

- a support for attachment to a garment, preferably a belt to be worn at the waist or over the shoulder, For definition, the expression "attachment support" designates any detachable element or not allowing the mobile phone to be carried on oneself. According to a variant, the support is in the form of a belt on which or inside which the components of the telephone are arranged. According to another variant, the support is a shell, a case which may include clips, or loops, or hooks, intended to hang it on the trouser belt, on the trouser edge itself, to a pocket, or any garment. . The shell may also include screws that the user can screw into a button fixed on the belt on any item of clothing.

The support can include the following accessories - A housing which can contain the microphone and the earpiece, or according to another variant, a hook making it possible to retain the microphone and the earpiece.

- Connectors to peripheral electronic devices coupled to the said electronic signal processing and telephone control circuits. In particular, one or more connectors are mounted near the pocket. The device can then be placed in the pocket.

- A lock fastening the belt, with coded lock with key unlocking.

- One or microphones coupled to analog digital converters, to reduce ambient noise compared to voice by subtracting the sounds coming from the different microphones from the sounds coming from the microphone near the mouth.

- A vibrator or buzzer warning of the reception of a telephone call.

- An alarm, for security.

- Several antennas arranged along the belt around the body, to improve reception of the signal whatever its source, with optional electromagnetic shielding consisting of a conductive plate placed between the transmitting antenna and the human body, for the thus protect from radiation.

- A jack to connect two headphones, and listen to music in stereo.

- A display screen to view the numbers dialed. Alternatively, the antenna is part of the cord connected to the earpiece and / or the microphone. According to other variants, the antenna is attached along this cord, or placed on the support, remote from the cord. It can receive an electromagnetic shield consisting of a conductive plate placed between the transmitting antenna and the human body. Preferably, the attachment or the exit of the antenna, when the support is belted, is situated vertically from the ear, in particular to improve the quality of reception of satellites with low orbit, when the body is in a standing position or seated. In order to give the antenna a rectilinear shape once extracted from the belt support or the unwinder, the antenna consists of a metal plate with shape memory, taking the form of a longitudinal portion of cylinder. But in the absence of interest from a vertical antenna integrated into said cord, the attachment point is on the lateral part opposite the ear, so as to bring the microphone closer to the mouth.

The microphone and the earpiece can be separated, but also integrated into a single headset. They are connected to the mobile phone by a thin electrical cord, which unrolls and coils.

The cord unwinder has a spiral return spring. A lever with a spring clamps the cord. A button on the lever allows by pressing to release from the pinch the cord, which rewinds a pulley.

A means of establishing a telephone conversation, done according to the following steps The owner of the mobile telephone pulls the earpiece. The unwinding of the cord towards the ear triggers an electrical contact which activates the electronic control circuit. This triggers the line and activates voice recognition. Announcement voice commands, such as the recipient's name or telephone number, are recognized, and incidentally repeated by the device. The control circuit then automatically starts dialing. In the event of non-voice recognition, the device can call a data processing center whose voice recognition system is improved, or transfer the order to teleoperators.

The electronic circuits according to their size are dissociated and connected together by flexible ply cords, thus reducing the thickness allowing an arrangement along the body. It should be noted that if we mention by distinguishing the electronic circuits for processing incoming, outgoing signal and the control circuit, this does not prejudge that these elements can be merged into a single multifunction electronic chip (DSP), such as authorizes the state of the art.

A protective insulating plastic sheath can cover the electronic circuits. The electric power source coupled with the various electronic elements will naturally be an accumulator, or a conventional stable battery, but also a fuel cell, a solar photoreceptor, a coiled wire making turn a mini-alternator when one draws the wire, a magnetized oscillator whose movement recharges an accumulator.

One of the most interesting features is that the telephone, in its variant in belt-shaped support, can have several connectors, connecting it to peripherals such as dial keypad with display, portable television, infrared transmitter, remote control, computer translator , electronic slate, stereo radio receiver, volatile memory for recording sound, music, and software, detectors, metal detectors, weapons, camera, digital camera, position or location detectors, medical devices, Internet browser, player barcode, contactless identification system, badge, taxi call beacon, door opening system, voice note taking alert system, paging, connection to power supply, emergency power supply, electronic payment, electronic book, game console, etc.

For example, the dial pad with associated display can be connected to the waist, on the side, and is placed in the pocket.

The mobile telephone can then become a communicating and programmable microcomputer, a central unit comprising a microprocessor associated with a volatile memory. It can thus download programs, with various functions, for example change of reception frequency, or of peripheral control.
