Abstract

A tactile vibration driver for use in a headphone includes a support structure, at least one suspension member suspending at least one rigid member relative to the support structure, and a plurality of magnetic members attached to the at least one rigid member and configured to drive oscillating movement of the at least one rigid member and the at least one suspension member so as to produce tactile vibrations during operation of the tactile vibration driver. An audio system includes the tactile vibration driver. A method of operating an audio system includes driving a plurality of magnetic members attached to a rigid member of the tactile vibration driver to cause oscillations of the plurality of magnetic members and the rigid member relative to a suspension member and producing tactile vibrations responsive to receipt of an electrical signal.

First claim

What is claimed is:

1. A tactile vibration driver for use in a headphone, comprising:
a support structure;
at least one suspension member;
at least one rigid member; and
a plurality of magnetic members, the plurality of magnetic members comprising:
a first pair of magnetic members located in a first location on the at least one rigid member and in a first location on the at least one suspension member; and
a second pair of magnetic members located in a second location on the at least one rigid member and in a second location on the at least one suspension member;

wherein the at least one suspension member suspends the at least one rigid member relative to the support structure; and
wherein the plurality of magnetic members is attached to the at least one rigid member and configured to drive oscillating movement of the at least one rigid member and the at least one suspension member so as to produce tactile vibrations during operation of the tactile vibration driver.

2. The tactile vibration driver of claim 1 , wherein each of the plurality of magnetic members is configured to be driven at an operating frequency during operation of the tactile vibration driver.

3. The tactile vibration driver of claim 1 , wherein at least one magnetic member of the plurality of magnetic members is attached to the at least one rigid member at a different plane than another magnetic member of the plurality of magnetic members.

4. The tactile vibration driver of claim 1 , further comprising a housing for the tactile vibration driver that is separate and distinct from a housing of an audio driver of the headphone.

5. The tactile vibration driver of claim 1 , wherein the tactile vibration driver substantially surrounds an audio driver of the headphone.

6. The tactile vibration driver of claim 1 , further comprising an opening defined by inner surfaces of the at least one rigid member.

7. The tactile vibration driver of claim 1 , wherein the at least one rigid member is oval-shaped, circular-shaped, semicircular-shaped, triangular-shaped, serpentine-shaped, square-shaped, rectangular-shaped, or trapezoidal-shaped.

8. An audio system including a media player configured to send an electrical audio signal to at least one tactile vibration driver of the audio system, the at least one tactile vibration driver comprising:
a support structure;
at least one suspension member;
at least one rigid member; and
a plurality of magnetic members, the plurality of magnetic members comprising:
a first pair of magnetic members located in a first location on the at least one rigid member and in a second location on the at least one suspension member; and
a second pair of magnetic members located in a second location on the at least one rigid member and in a second location on the at least one suspension member;

wherein the at least one suspension member is coupled to the at least one rigid member and the support structure; and
wherein the plurality of magnetic members is attached to the at least one rigid member and each magnetic member of the plurality of magnetic members is configured to oscillate relative to the support structure and generate tactile vibrations responsive to receipt of the electrical audio signal.

9. The audio system of claim 8 , wherein the at least one tactile vibration driver is configured to contact a surface of a head of a user.

10. The audio system of claim 8 , wherein the at least one tactile vibration driver is secured to a headband of a headphone.

11. The audio system of claim 8 , wherein the at least one tactile vibration driver is disposed within an ear cup of a headphone.

12. The audio system of claim 8 , further comprising a headphone including a headband, a plurality of tactile vibration drivers secured to the headband.
