A headrest waveguide extends the dipole speaker path to boost bass SPL near the listener while reducing leakage and vibration transmission.
Multiple acoustic conduits route sound to the rear cover and flexible display, keeping speaker and receiver functions usable in folded and unfolded states.
A single driving motor switches between sound generation and haptic vibration to cut internal space use and device cost.
An angled bass driver and elastomeric reflector-damper plate boost bass in a compact speaker while reducing acoustic frequency distortion.
A through hole and connecting structure link speaker and shield-can spaces to improve low-frequency resonance without enlarging the device.
Adjustable acoustic ports and damping layers let a modular speaker cabinet tailor bass and sound profile while limiting vibration.
A limiting assembly between the clamping plate and damping component restrains magnetic circuit movement to prevent tearing under impact.
Aligned ports and three seals isolate speaker outputs inside a wearable arm, improving audio privacy, sound quality, and compact assembly.
An anti-overflow layer on the upper clamping plate blocks damping material overflow during molding, preserving vibration space and speaker performance.
A shield can and PCB form a hermetic speaker resonance space, improving low-frequency sound quality without increasing device volume.
Sound-guiding holes route internal waves to interfere with housing leakage in bone conduction speakers, cutting airborne sound without bulkier magnets.
Cooling channels around the speaker driver and in an external pipe circulate liquid to move heat out of the cavity and reduce thermal damage risk.
COF porous material increases loudspeaker cavity virtual volume while improving low-frequency response and acoustic consistency.
Resonant passages and a buffer section absorb selected frequencies, reducing enclosure interference and preserving a consistent speaker amplitude spectrum.
Adjacent piezoelectric units vibrate in opposite directions through shared acoustic cavities to raise low-frequency output in a compact speaker.
Fixed transducer and sensor supports position ANC components in neonatal incubators to reduce noise while preserving care-device function.
Existing home voice systems may require nearby IoT devices; domestic sensors and satellite modules enable connection without layout changes.
