Dual-Driver Speaker
US Patent:
D354058, Jan 3, 1995
Filed:

Piezoelectric Loudspeaker With Thermal Protection
US Patent:
4864624, Sep 5, 1989
Filed:
Mar 30, 1988
Appl. No.:
7/175001
Inventors:
Thomas H. Tichy - Albuquerque NM
International Classification:
H03G 1100, H04R 2900
US Classification:
381 55
Abstract:
A preferred embodiment of a thermal protection circuit for a piezoelectric speaker includes a PTC resistor connected in series with the speaker and a second PTC nonlinear resistive element, such as a light bulb, connected in parallel with the resistor. This protects the speaker from failure due to overheating caused by excessive drive signals without causing audio distortion during infrequent excessive drive signals of a short duration.
Piezoelectric Audio Transducer
US Patent:
5514927, May 7, 1996
Filed:
Feb 28, 1994
Appl. No.:
8/203469
Inventors:
Thomas H. Tichy - Albuquerque NM
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H01L 4108
US Classification:
310330
Abstract:
A piezoelectric transducer (100) may be achieved by mounting a piezoelectric bender (101) within a housing (102). Maximum resonation may be obtained by mounting the piezoelectric bender (101) on a single post (103). The housing (102) is constructed to have essentially the same geometry as the piezoelectric bender (101) and is separated by a predetermined distance (104). This predetermined distance (104) provides an acoustic impedance such that sound may resonate from the transducer.
Method Of Mounting A Piezoelectric Helmholtz Transducer On A Printed Circuit Board
US Patent:
4630342, Dec 23, 1986
Filed:
Mar 10, 1986
Appl. No.:
6/838441
Inventors:
Thomas H. Tichy - Albuquerque NM
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H01L 4122
US Classification:
29 2535
Abstract:
A helmholtz resonator is driven by a piezoelectric element and is suited for mounting to a printed circuit board. The resonator includes a resonant chamber defined by bottom, top, and side walls, and at least two ports that provide access to the chamber. The ports are contiguous to the bottom and side walls so that any liquid entering the chamber during the printed circuit board cleaning process can exit via the ports. This arrangement overcomes the contamination problem existing in prior art resonators having a single port.
Suppression Of Cursor Control During Tactile Feedback Operation
US Patent:
6873316, Mar 29, 2005
Filed:
Feb 1, 2001

International Classification:
G09G005/08, G06F019/00
US Classification:
345157, 345161, 345163, 463 30, 463 37
Abstract:
An apparatus for filtering or suppressing a tactile feedback to a user of a computer cursor control device such as a pointing stick is provided. A pzt material is first mounted to a semi-rigid material such as by bonding the pzt material to a metal substrate. When an ac signal is applied to this assembly it vibrates. By coupling this mechanical vibration to the pointing stick, the user can sense the feedback. This can be used, for example, to provide a tactile feedback when the user depresses the pointing stick to cause a “mouse click. ” In order to prevent unwanted cursor movement on the display, a suppression circuit is provided that filters out the spurious signals or completely deactivates cursor movement during activation of the tactile feedback.
Mechanical-Vibration-Cancelling Piezo Ceramic Microphone
US Patent:
5251264, Oct 5, 1993
Filed:
Mar 25, 1992
Appl. No.:
7/857210
Inventors:
Thomas H. Tichy - Albuquerque NM
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H04R 2500, H04R 300
US Classification:
381173
Abstract:
In applications where mechanical vibrations should not cause a microphone to produce an output signal, opposing and series connected PZT elements (A and B) are used to cancel mechanical shock or vibration that might cause an output voltage or signal. Acoustic waves cause the PZT elements to deflect in opposite directions which when the sensors (A and B) are electrically in series produce a measurable output.

Dual Function Transducer Housing
US Patent:
5517574, May 14, 1996
Filed:
Dec 22, 1994
Appl. No.:
8/361630
Inventors:
Thomas H. Tichy - Albuquerque NM
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H04R 2500
US Classification:
381188
Abstract:
A dual function transducer housing (100), includes a narrow profile housing having top and bottom cavities (105, 103) and a ringer side port (106). The top and bottom cavities (105, 103) are adapted to receive a ringer diaphragm and a speaker diaphragm, respectively. The top cavity (105) is in communication with the ringer side port (106). A ringer output signal is providable through the ringer side port (106) and a speaker output is providable from the housing (100).
