20090072768 | USE OF AN ACCELEROMETER TO CONTROL VIBRATOR PERFORMANCE - A mobile device includes a vibrator, an accelerometer that senses a parameter of rotation, and a processor. The vibrator includes a drive motor and a drive circuit. The accelerometer senses a speed of rotation of the vibrator. The processor analyzes the sensed speed of rotation and generates a drive voltage that is received by the drive circuit to adjust the drive motor to produce a pre-determined, desired rotational speed. In another embodiment, the accelerometer senses an amplitude of a vibration produced by the vibrator. The processor analyzes the sensed amplitude of a vibration and generates a drive voltage that is received by the drive circuit to adjust the drive motor to produce a pre-determined, desired vibration amplitude. The processor may also compare the sensed parameter with a pre-determined desired parameter of rotation and generate a signal responsive to a result of the comparison and based on stored vibrator calibration curves. | 03-19-2009 |

20090154756 | Printed Circuit Board for a Flat-Panel Speaker - A flat-panel speaker is attached to an exterior surface of a printed circuit board (PCB) housed within a consumer electronic device. Rather than place the flat-panel speaker within a sealed speaker box and then attach the speaker box to the PCB, as is conventional, the present invention attaches the flat-panel speaker to the exterior surface of the PCB without the speaker box. Removing the speaker box allows designers to reduce the dimensions of the device, and to minimize the complexity of the device. | 06-18-2009 |
20090156273 | Loudspeaker for a Clamshell Wireless Communication Device - A clamshell-type wireless communication device has a flip, a base, and a hinge that pivotably connects the flip to the base. The flip pivots relative to the base between an open position and a closed position. An earpiece speaker in the flip renders the voice of a remote party to a user when the flip is in the open position. A loudspeaker within the hinge also renders audible sound to the user. The loudspeaker is positioned within the hinge such that neither the flip nor the base obstructs the audible sound projected by the loudspeaker regardless of whether the flip is in the open position or the closed position. | 06-18-2009 |
20090196442 | Low-Profile Piezoelectric Speaker Assembly - A low-profile speaker assembly comprises a substrate and a substantially plan piezoelectric element disposed in a plane substantially parallel to the substrate and mechanically connected to the substrate at one or more edges.
