Multistage tactile sound device
A tactile sound device in proximate contact with a user, comprising a multistage arrangement of vibrotactile materials to impart visceral sensations to a user. The device imparts a physical sensation via a multistage arrangement of vibrotactile materials embodied in a wearable or seated configuration, in response to a wired or wireless signal input.
1. A tactile device, comprising:
a membrane of a vibrotactile assembly, the membrane including a composite material comprising:
a first region at a first depth proximal to a user; and
a second region at a second depth deeper than the first depth relative to the user; and
one or more electroactive components that translate at least one electrical signal into motion, the electroactive components attached along or embedded into the second region of the membrane,
wherein at least part of the second region is between the electroactive components and the first region of the membrane, the second region of the membrane dampening and dissipating the motion from the electroactive components before the motion reaches the first region of the membrane;
wherein the first region of the membrane is adapted to transfer the damped and dissipated motion from the second region of the membrane to the user, and
wherein the membrane includes a vertical portion adapted to be proximate a spine of the user and a horizontal portion extending horizontally beyond the vertical portion and positioned towards a bottom of the vertical portion.
2. The tactile device of claim 1 , wherein the first region is rigid, and the second region comprises a microcellular material.
3. The tactile device of claim 1 , wherein the second region has greater vibration dampening characteristics than the first region.
4. The tactile device of claim 1 , wherein the first region comprises a thermoplastic or composite material.
5. The tactile device of claim 4 , wherein the first region comprises polypropylene.
6. The tactile device of claim 1 , wherein the second region comprises a microcellular elastomer, urethane, polyurethane or rubber.
7. The tactile device of claim 1 , wherein:
the first region includes a first layer of the membrane and the second region includes a second layer of the membrane; and
a surface area of the second layer is less than a surface area of the first layer.
8. The tactile device of claim 1 , wherein the membrane includes:
a second horizontal portion extending horizontally beyond the vertical portion towards a top of the vertical portion.
9. The tactile device of claim 1 , wherein the one or more electroactive components comprise a transducer.
10. The tactile device of claim 1 , wherein the one or more electroactive components comprise a first electroactive transducer and a second electroactive transducer spaced apart from the first electroactive transducer.
11. The tactile device of claim 1 , further comprising:
a circuit assembly that receives an audio signal input and powers the one or more electroactive components based on the audio signal input.
12. The tactile device of claim 11 , wherein the circuit assembly comprises:
an amplifier that powers the one or more electroactive components; and
a filter that filters the audio signal input into a filtered signal and provides the filtered signal to the amplifier.
13. The tactile device of claim 12 , wherein the filter removes frequencies above a frequency response range of the one or more electroactive components.
14. The tactile device of claim 11 , wherein the circuit assembly applies sound effects to the audio signal input.
15. The tactile device of claim 11 , further comprising:
a display to output light based on a characteristic of the audio signal input or an audio signal output.
16. The tactile device of claim 1 , further comprising:
a circuit assembly that powers the electroactive components, the circuit assembly generating car-engine effects.
17. The tactile device of claim 1 , wherein the tactile device is situated inside a textile cover.
18. The tactile device of claim 1 , wherein the tactile device comprises a strap or clasp to secure the device to a seat.
19. The tactile device of claim 1 , wherein the tactile device is situated inside a seat.
20. The tactile device of claim 1 , wherein the tactile device is integrated inside a backpack on a side proximal to the user's back.
