Transducer for tactile applications and apparatus incorporating transducers
View Patent ↗The disclosed transducer the can transfer an audio signal into a full-spectrum tactile wave over a frequency of 10 Hz-2 KHz. Upper and lower springs of the transducer produce vibrations via a coil/magnet in a manner similar to a conventional speaker, but the transducer uses a novel arrangement of elements, such as two south-to-south coils and carbon fiber springs, so as to produce the vibrations tactilely. The transducers can be tuned for specific applications and can be attached or formed integrally with a support surface. When attached or incorporated into a chair, massage table or other human-support structure, the transducer creates a sonic environment that surrounds and permeates the body with vibration, providing a direct experience of mental desired states. When connected to any full fidelity sound system, a support structure, a full frequency response process promotes a state of relaxation in the listener.
1. A transducer comprising:
an upper spring assembly having an upper spring;
a magnet assembly having a magnet positioned on a stud;
a main plate assembly having a main plate with an aperture;
a coil assembly having a first coil, a second coil, and an electrical power source attached to each coil; and
a lower spring assembly having a lower spring,
wherein:
the upper spring and the lower spring are comprised of surfaces and are secured at a peripheral region thereof to the main plate assembly;
the coil assembly is secured to the main plate so as to position the first coil and second coil adjacent opposite sides of the aperture and the electrical power source is attached to the first coil and the second coil so that the first and second coils are positioned in said a south-to-south configuration; and
the stud of the magnet assembly is secured to the upper spring assembly and the lower spring assembly and suspends the magnet within the aperture and coil assembly.
2. The apparatus of claim 1 , wherein the surfaces of the upper and lower springs include a profile with an outer portion radius and an inner portion radius.
3. The apparatus of claim 2 , wherein the surfaces of the upper and lower springs include a nipple portion that is secured to the stud.
4. The apparatus of claim 1 , wherein the surfaces of the upper and lower springs are made of carbon fiber composite.
5. The apparatus of claim 4 , wherein the carbon fiber composite includes aramid fibers.
6. The apparatus of claim 1 , wherein the surfaces of the upper and lower springs form a general appearance of a donut shape when secured to the main plate.
7. The apparatus of claim 6 , wherein the surfaces of the upper and lower springs have a profile that incorporates at least two radii that are related to each other as being members of a Fibonacci sequence.
8. The apparatus of claim 1 , further comprising mounting means associated with the main plate assembly.
9. The apparatus of claim 1 , further comprising mounting means associated with the magnet assembly stud.
10. The apparatus of claim 8 , wherein the surface of the upper spring further comprises a body support means.
11. The apparatus of claim 10 , wherein said body support means is selected from the group consisting of chair panels, table panels, and floor panels.
12. The apparatus of claim 9 , further comprising a resonating body support panel having a geometry based upon a Fibonacci sequence and said mounting means is attached to a location on the resonating body support panel associated with a tonal center.
13. The apparatus of claim 1 , wherein the stud of the magnet assembly is secured to the upper spring assembly and the lower spring assembly with a resilient means for allowing the spring tension to be adjusted for tuning purposes.
14. The apparatus of claim 13 , wherein the resilient means includes pliable o-rings on either side of the magnet on the stud.
15. The apparatus of claim 1 , further comprising the main plate being formed of heat conductive material of sufficient surface area to provide a heat sink for said transducer.
16. A method of using the transducer of claim 1 , comprising
supplying an amplified audio source as the electrical power source for each coil; and
driving the transducer in a range of 10 Hz-2 KHz.
17. The method of claim 16 , further comprising:
selecting the audio source associated with stress reduction; and
applying the audio source to a human body with the transducer.
18. The method of claim 17 , further comprising applying the audio source to the human body by tactile contact of the transducer with the human body.
19. The method of claim 16 , further comprising:
supplying the amplified audio source selected from the group consisting of mono, stereo, 4.1 multi-channel, 5.1 multi-channel, 4.2 multi-channel, 2.2 multi-channel, and combinations thereof.
