A smart speaker is disclosed with an interactive speaker grille. In one embodiment a smart speaker comprises a housing with a speaker grille comprising a plurality of openings. Circuitry coupled to the speaker grille is configured to sense direct user interaction with one or more of a plurality of regions of the speaker grille and to generate corresponding electrical signals indicative of the one or more regions of the speaker grille experiencing direct user interaction. The circuitry can include portions in the path of sound transmission to detect user interaction with regions of the grille and portions outside the path of sound transmission for controlling aspects of the smart speaker (e.g. speaker volume, radio station or media stream selection) based on the particular regions touched.

In one embodiment a sound generating system comprises: a housing; a speaker located at least partially inside the housing; and an interactive faceplate subassembly comprising: a front surface, wherein a portion of the front surface contains a first plurality of openings forming a speaker grille; a display operable to display through a first portion of the front surface; the display disposed behind the front surface of the interactive faceplate subassembly and coupled to a second surface having a second plurality of openings, and wherein at least one of the openings in the second plurality of openings aligns with one or more of the openings in the first plurality of openings, thereby promoting improved sound transmission from the speaker.

Keyboards for electronic devices with keys having integrated speakers are disclosed herein. An example keyboard includes a key having a key cap and a speaker coupled to the key cap. The speaker is disposed in or at least partially covered by the key cap.

An electrical switch responds to acoustic inputs. A microphone integrated into the electrical switch generates electrical signals in response to the acoustic inputs. A network interface integrated into the electrical switch provides addressable communication with controllers, computers, and other networked devices. The electrical switch may thus be installed or retrofitted into the electrical wiring of all homes and businesses. Users may thus speak voice commands, which are received by the electrical switch and sent for voice control of appliances and other automation tasks.
