Definitions
- the document FR-A-2,521,808 discloses a ribbon speaker comprising a permanent magnet defining a gap in which is disposed a ribbon. The free ends of the ribbon are connected to electrical contacts. According to one embodiment, the ribbon consists of a series of strips that can be wound on a flexible support.
- a product such as the plasma chamber was close to the physical performance of the air since it acted on the particles of the air.
- the invention provides an apparatus according to claim 1 and its use as defined in claim 4, as well as a system as defined in claim 5.
- the other claims define preferred embodiments.
- the present apparatus complements current sound reproduction systems such as the loudspeakers used. These speakers create the necessary sound bases but without any refinement, and in particular have a characteristic defect which is the non respect of the intermodulation sound.
- the present method and apparatus superimposes the coarse sound signal of the speakers,
- This sound information is the amplification and precise order of the harmonics in space-time.
- the sound emission is thus carried out by the sonic micro-vibrations of the electrical wires of the solenoid (s).
- a variant of the apparatus is a solenoid supplemented with at least one magnet inside or outside, which activates its effect but decreases its sensitivity due to the remanence of the magnetic field of the magnet which imposes its Magnetic field constant, masking the Earth's magnetic field.
- the apparatus is constituted ( Fig 1 ) by at least one winding of electrical wires (1) in this case of figure 1 / 10th of a millimeter wound on a flexible support (2) made of polymer 10 cm long and 0.8 cm in diameter.
- the impedance of this winding is 8 Ohms, the winding is characterized in that each layer (3, 4) is wound in the same winding direction, the return wire (5) being placed along the winding.
- This winding mode allows micro-vibrations between the turns, given the difference in voltage between the turns of the first and second layers. These micro-vibrations participate in the sound amplification of the harmonics.
- This device is coupled to an audio electrical signal of a acoustic enclosure or an acoustic power supply.
- This device comes in addition to usual electro-acoustic transducers.
- This apparatus is made by a person skilled in the art and represents a non-limiting example of embodiment of this method.
- This device ( Fig 1 ) is integrated ( Fig 2
- the electroacoustic transducer solenoid 10 of the present apparatus is freely mounted in the ambient air next to the tweeter 11. It is mounted on the facade mechanically held by two screws 12. and is electrically mounted with the tweeter 11 by the electrical wires (5, 6) from the electro-acoustic filter (7).
- the winding of the electric wire can have any type of shape, for example round, conical, square or any other shape.
- This assembly is not exhaustive of the application of the device.
- This new electro-acoustic transducer could be mounted directly on the general audio supply between the amp and the speaker.
- These new electro-acoustic transducers can be connected together in series or in parallel or both.
- These acoustic transducers are harmonic amplifiers.
- the present method and electro-acoustic apparatus limited to a winding of electric wire without membrane gives an unmatched acoustic fineness.
- This apparatus and method can be used on all audio, audio-video and all communication systems such as telephones, radio, as well as by the medical world for improving the hearing comfort of the hearing impaired.
