Abstract

An apparatus including a microphone; a speaker including at least one vibrating element and at least one movable section, where the at least one vibrating element is configured to at least partially move the at least one movable section to generate sound waves from the at least one movable section; and at least one vibration dampening member between the microphone and the at least one movable section, where the at least one vibration dampening member is suitably positioned in a path of vibration transmission between the at least one vibrating element and the microphone, where the at least one vibration dampening member is configured to absorb vibrations when the movable section is actuated by the at least one vibrating element.

First claim

What is claimed is:

1. An apparatus comprising:
a microphone;
a speaker comprising at least one vibrating element and at least one movable section, wherein the at least one movable section is at least one section of the apparatus and at least in part covers the apparatus, where the at least one vibrating element is configured to at least partially move the at least one movable section to generate sound waves from the at least one movable section; and
at least one vibration dampening member between the microphone and the at least one movable section, where the at least one vibration dampening member is suitably positioned in a path of vibration transmission between the at least one vibrating element and the microphone, where the at least one vibration dampening member is configured to absorb vibrations when the movable section is actuated by the at least one vibrating element;
wherein a connection of the speaker to a frame of the apparatus comprises a first section at a first location of the at least one movable section and a second section at a second location of the at least one movable section,
wherein the first section comprises a soft suspension, wherein the second section comprises a harder suspension than the first section, wherein the at least one vibrating element is located away from the second location of the at least one movable section, and wherein the apparatus is an electronic device.

2. An apparatus as in claim 1 where the at least one vibration dampening member extends across a majority of a width of the at least one movable section for 10 percent or more of a lower half of the at least one movable section.

3. An apparatus as in claim 1 where the at least one vibration dampening member is located substantially in a lower half of the apparatus so as to substantially absorb vibrations before the vibrations reach the microphone.

4. An apparatus as in claim 1 where the at least one movable section comprises at least one of: at least one display element; a display; a display window and an apparatus cover, and where the at least one vibration dampening member is coupled to a rear side of the at least one movable section.

5. An apparatus as in claim 1 where the at least one movable section comprises at least one display element, and where the at least one vibration dampening member comprises at least one of pressure sensitive adhesive (PSA) tape and foam.

6. An apparatus as in claim 1 where the at least one movable section comprises at least one display element, and where the at least one vibration dampening member is located at a lower half of the at least one display element, where the at least one vibration dampening member comprises an edge having a non-straight and/or non-uniform shape.

7. An apparatus as in claim 1 where the first section comprising the soft suspension of the at least one movable section is between the at least one movable section and the frame, where the second section comprising the harder suspension of the at least one movable section is between the at least one movable section and the frame, and where the at least one vibrating element is located proximate the at least one movable section at the first location of the at least one movable section so as to move the at least one movable section substantially using the first section based on the soft suspension of the at least one display element.

8. An apparatus as in claim 1 further comprising:
at least one printed wiring board;
a processor connected to the at least one printed wiring board;
a memory comprising software connected to the at least one printed wiring board;
a camera connected to the at least one printed wiring board; and
a battery connected to the at least one printed wiring board.

9. A method comprising:
providing a speaker, where the speaker comprises at least one vibrating element and at least one movable section, wherein the at least one movable section is at least one section of an apparatus and at least in part covers the apparatus, where the at least one vibrating element is configured to at least partially move the at least one movable section to generate sound waves from the at least one movable section; and
locating at least one vibration dampening member between a microphone and the at least one movable section, where the at least one vibration dampening member is suitably positioned in a path of vibration transmission between the at least one vibrating element and the microphone, where the at least one vibration dampening member is configured to absorb vibrations when the movable section is actuated by the at least one vibrating element;
further comprising the speaker being connected to a frame by a connection comprising a first section at a first location of the at least one movable section and a second section at a second location of the at least one movable section, where the first section comprises a soft suspension, and where the second section comprises a harder suspension than the first section, and wherein the at least one vibrating element is located away from the second location of the at least one movable section, and wherein the apparatus is an electronic device.

10. A method as in claim 9 where the at least one movable section comprises at least one display element, and where the at least one vibration dampening member is located across a majority of a width of the at least one display element for 10 percent or more of a lower half of the at least one display element.

11. A method as in claim 9 where the at least one movable section comprises at least one display element, and where the at least one vibration dampening member is located against a majority of a lower half of the at least one display element.

12. A method as in claim 9 where the at least one movable section comprises at least one of: at least one display element; a display; a display window and an apparatus cover, and where the at least one vibration dampening member is coupled to a rear side of the at least one movable section.

13. A method as in claim 9 where the at least one vibration dampening member comprises at least one of pressure sensitive adhesive (PSA) tape and foam.

14. A method as in claim 9 where the at least one movable section comprises at least one display element, and where the at least one vibration dampening member is located at a lower half of the at least one display element, where the at least one vibration dampening member comprises an edge having a non-straight and/or non-uniform shape.

15. A method as in claim 9 where the at least one movable section comprises at least one display element, where the first section comprising the soft suspension of the at least one display element is between the at least one display element and the frame, where the second section comprising the harder suspension of the at least one display element is between the at least one display element and the frame, and where the at least one vibrating element is located proximate the at least one display element at the first location of the at least one display element so as to move the at least one display element substantially using the first section based on the soft suspension of the at least one display element.

16. An apparatus comprising:
a microphone;
a speaker comprising at least one vibrating element and at least one movable section, wherein the at least one movable section is at least one section of the apparatus and at least in part covers the apparatus, where the at least one vibrating element is configured to at least partially move the at least one movable section to generate sound wave
