Mouthpiece/Microphone Attachments TRIZ Cases

A battery holder uses a resilient positioning member to accommodate either one large or two small batteries in a wireless device.

Self-actuating piezoelectric valve opens relief port to absorb air burst impact, preventing diaphragm damage from acoustic shock.

Flexible wire positions microphone along auricle to measure ear canal transfer characteristics without blocking the ear canal.

A microphone array generates spatial distribution information from phase differences to identify overlapping speech signals.

A multifunctional Bluetooth microphone integrates a touch screen interface with dual-channel reception for voice signal processing.

Differential axial and radial spring stiffness isolates structure-borne sound while maintaining compact device volume.

A microphone assembly uses a movable inner sleeve to shift relative to an outer sleeve, altering sound hole exposure.

A hearing aid microphone cover uses oleophobic filtration media to block contaminants while allowing sound transmission.

Segmented adhesive sheets prevent membrane sagging and transducer contact, maintaining sound quality in compact electronic devices.

Open-pore foam drains water residues from action camera microphone holes, preventing acoustic obstruction after immersion.

Separate input units on a remote controller generate independent voice recognition and microphone request signals, enabling simultaneous function activation.

An acoustic perforated sheet filters sound waves passing through a microphone inlet to attenuate specific frequency ranges.

A microphone adjustable joint uses a ball and socket mechanism to enable constrained swiveling movement for precise orientation.

Processor selects screen or speaker output based on command result information amount, preventing auditory overload and improving usability.

A digital mirror assembly integrates multiple cameras, LED flash lights, and a touch screen on a single base unit for versatile photo capture.

A rotatable shield covers the mouth to block sight while keeping the microphone stem clear.

Sliding grooves and fasteners adjust the ear position, eliminating redesigns for different device sizes.

A composite acoustic membrane uses segmented porous and nonporous regions to transmit sound while blocking liquid ingress.

Merging spatial and ear-canal transfer characteristic measurements into one unit eliminates microphone variability errors while maintaining high precision.

A magnetic microphone mounting adapter couples to vehicle interiors via a disc-shaped housing and magnet, eliminating precise alignment requirements.
