Interactive Speaker Grille Layout for Sound and Sensor Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart speakers face challenges in integrating indirect input sensors with speaker elements, as the size of the speaker element impedes the performance of these sensors, competing for space and affecting their field of view and functionality.
Innovation Solution
Incorporating an environmental-sensing faceplate subassembly with a circuit board placed in the path of sound transmission, featuring a grille with openings that align with those on the circuit board, allowing indirect input sensors to sense the environment while promoting improved sound transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the speaker element size is increased to provide sufficient sound output in small enclosures, then the speaker performance is improved, but the field of view and performance of indirect input sensors deteriorate due to space competition and obstruction
Solution Approach 1:
The faceplate is segmented into multiple regions: a first region with a speaker grille for sound transmission and a second region with openings for sensor access. This segmentation allows the speaker element and sensor to occupy different spatial zones, reducing mutual obstruction while maintaining both sound output and sensor field of view in compact enclosures
Solution Approach 2:
The patent transitions from a traditional single-plane speaker-grille configuration to a multi-dimensional arrangement where the faceplate contains distinct first and second regions. The sensor is positioned in the second region with its own opening pattern, creating a layered spatial structure that resolves the two-dimensional space conflict between speaker and sensor
2Power
If the speaker element occupies more space in the enclosure, then the sound transmission capability is improved, but the space available for sensor placement and field of view is reduced
Solution Approach 1:
Different regions of the faceplate are assigned different functional qualities: the first region is optimized for sound transmission with a speaker grille pattern, while the second region is optimized for sensor access with a different opening pattern. This local differentiation allows each component to perform its function effectively without compromising the other
Solution Approach 2:
The faceplate serves multiple functions simultaneously: it acts as a protective cover, a sound transmission interface through the first region, and a sensor access interface through the second region. This multi-functionality consolidates speaker and sensor pathways into a single component, maximizing space utilization in compact enclosures

AI summary
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.
