Abstract
An electronic device has an exterior housing with a piezoelectric speaker disposed in an opening formed within the housing. The piezoelectric speaker includes a speaker diaphragm that is secured within the opening with a vibration isolator. The vibration isolator allows the diaphragm to vibrate independently from the housing.
Claims24
An electronic device comprising:
- a housing including a transparent cover attached to a housing body having a rear portion and a plurality of sidewalls extending between the rear portion and the transparent cover;
- an opening formed through the transparent cover;
- a piezoelectric speaker diaphragm disposed within the opening and positioned to be substantially coplanar with an exterior surface of the transparent cover;
- a piezoelectric receiver attached to the speaker diaphragm;
- and
- a vibration isolator coupled between the piezoelectric speaker diaphragm and the transparent cover to enable the piezoelectric speaker diaphragm to vibrate independently from the transparent cover.

An electronic device comprising:
- a transparent cover disposed over a graphical display of the electronic device, the transparent cover having an opening formed there through;
- a housing body having a rear portion and a plurality of sidewalls extending between the rear portion and the transparent cover;
- a piezoelectric speaker aligned with the opening, the piezoelectric speaker including a speaker diaphragm and a piezoelectric receiver attached to the speaker diaphragm, wherein the speaker diaphragm is substantially coplanar with an exterior surface of the transparent cover;
- and
- a vibration isolator coupled between the speaker diaphragm and the transparent cover to enable the speaker diaphragm to vibrate independently from the transparent cover.
