Abstract

A speaker comprises a support structure having a circumferentially extending rim, a vibration member configured to be displaced relative to the support structure during operation of the speaker, and a suspension member suspending the vibration member relative to the support structure. The suspension member includes a radially outer portion attached to the rim of the support structure, a radially inner platform portion attached to the vibration member, and a plurality of beams. Each beam of the plurality of beams may extend from the radially outer portion to the radially inner platform portion. The plurality of beams is configured such that a resonant frequency of the vibration member attached to the radially inner platform portion of the suspension member scales linearly with a beam width of the beams of the plurality of beams.

Claims (39)

1. An apparatus, comprising:

a speaker, including:

a support structure having a circumferentially extending rim;

a vibration member configured to be displaced relative to the support structure during operation of the speaker for generating vibrations; and

a suspension member suspending the vibration member relative to the support structure, the suspension member including:

a radially outer portion attached to the rim of the support structure;

a radially inner platform portion attached to the vibration member; and

a plurality of beams, each beam of the plurality of beams extending from the radially outer portion to the radially inner platform portion, wherein the plurality of beams is configured such that a resonant frequency of the vibration member attached to the radially inner platform portion of the suspension member scales linearly with a beam width of the beams of the plurality of beams.

2. The apparatus of claim 1 , wherein the beams of the plurality of beams are configured such that the resonant frequency of the vibration member attached to the radially inner platform portion of the suspension member is between approximately 40 Hz and approximately 60 Hz.

3. The apparatus of claim 1 , wherein the vibration member comprises at least one of a physical magnet and an electrical coil configured to generate a magnetic field responsive to an audio signal.

4. The apparatus of claim 1 , wherein the suspension member comprises a metal suspension member.

5. The apparatus of claim 1 , wherein each beam of the plurality of beams extends in a spiral direction from the radially outer portion of the suspension member to the radially inner platform portion.

6. The apparatus of claim 5 , wherein each beam of the plurality of beams extends in a common spiral direction from the radially outer portion of the suspension member to the radially inner platform portion.

7. The apparatus of claim 5 , wherein each beam of the plurality of beams extends continuously without bends in the spiral direction from the radially outer portion of the suspension member to the radially inner platform portion.

8. The apparatus of claim 1 , wherein the beams do not intersect one another.

9. The apparatus of claim 1 , wherein each beam of the plurality of beams extends from the radially outer portion to the radially inner platform portion, and in a spiral direction from the radially outer portion of the suspension member to the radially inner platform portion.

10. The apparatus of claim 1 , further comprising a headphone including the speaker and a device for operatively coupling the speaker with a media player configured to send an electrical audio signal to the speaker.

11. The apparatus of claim 10 , wherein the speaker is configured to be disposed as one of:

within an ear of a person using the headphone;

on an ear of a person using the headphone; and

over an ear of a person using the headphone.

12. A method of forming a speaker, the method comprising:

providing a suspension member including a radially outer portion, a radially inner platform portion, and a plurality of beams, each beam of the plurality of beams extending from the radially outer portion to the radially inner platform portion, the beams of the plurality of beams configured such that a resonant frequency of a vibration member attached to the radially inner platform portion of the suspension member scales linearly with a beam width of the beams of the plurality of beams;

attaching the vibration member to the radially inner platform portion of the suspension member; and

attaching the radially outer portion of the suspension member to a rim of a support structure such that the vibration member is suspended relative to the support structure.

13. The method of claim 12 , further comprising forming the suspension member.

14. The method of claim 13 , wherein forming the suspension member comprises configuring the beams of the plurality of beams such that the resonant frequency of the vibration member attached to the radially inner platform portion of the suspension member is between approximately 40 Hz and approximately 60 Hz.

15. The method of claim 13 , wherein forming the suspension member comprises forming each beam of the plurality of beams to extend in a spiral direction from the radially outer portion of the suspension member to the radially inner platform portion.

16. The method of claim 13 , wherein forming the suspension member comprises forming each beam of the plurality of beams to extend continuously without bends in the spiral direction from the radially outer portion of the suspension member to the radially inner platform portion.

17. The method of claim 12 , further comprising:

sampling an electrical audio signal for a media device;

determining a peak bass frequency of the electrical audio signal; and

configuring the beams of the plurality of beams of the suspension member such that the resonant frequency of the vibration member attached to the radially inner platform portion of the suspension member is at least approximately equal to the peak bass frequency of the electrical audio signal of the media device.

18. The method of claim 17 , further comprising packaging the speaker and the media device in a common package for sale or distribution.

19. A kit including at least one speaker and a storage device storing media content configured to generate an electrical audio signal, wherein the at least one speaker comprises:

a support structure having a circumferentially extending rim;

a vibration member configured to be displaced within the support structure for generating vibrations responsive to receipt of the electrical audio signal when sent to the at least one speaker by a media player playing the media content; and

a suspension member suspending the vibration member relative to the support structure, the suspension member including a radially outer portion attached to the rim of the support structure and a radially inner platform portion attached to the vibration member, the suspension member further including a plurality of beams, each beam of the plurality of beams extending from the radially outer portion to the radially inner platform portion, wherein the beams of the plurality of beams are configured such that a resonant frequency of the vibration member attached to the radially inner platform portion of the suspension member is at least approximately equal to a peak bass frequency of the electrical audio signal.

20. The kit of claim 19 , wherein the media content is selected from the group consisting of music, a movie, and a video game.
