Loudspeaker Transducer Fixing TRIZ Cases

Sound guiding holes in the housing redirect internal vibrations to create destructive interference, reducing leakage by 20 dB without adding weight.

Crimping the exposed lead wire directly onto the housing conductive portion eliminates false welding risks and reduces material costs.

A speaker cabinet positions an acoustic duct opening at a side wall center to reduce standing wave influence on sound radiation.

Partitioned chambers isolate loudspeakers from microphones, suppressing vibration noise while maintaining compact chassis size.

A contact member headrest integrates a propagation obstruction between left and right speakers to physically block sound wave paths.

Segmented multi-channel vents distribute airflow across three dimensions, resolving blockage bottlenecks that cause wind noise and poor bass response.

Sound-absorbing cotton in a speaker module front cavity prevents standing waves, improving high-frequency sensitivity without structural changes.

A cover body gap forms a sound outlet channel between the frame and cover to reduce space occupation.

Double wall structure transmits acoustic energy through an intermediate layer without exterior panel openings.

Segmented elastic bridge design consumes kinetic energy to limit low frequency resonance transmission in notebook computers.

Three-dimensional mesh fiber pads transmit sound through a vehicle headrest, resolving acoustic quality loss and user discomfort from hard speaker frameworks.
