Diaphragm Mounting/Tensioning TRIZ Cases

A bobbin-integrated flange enables resin-molded damper attachment with higher positioning accuracy and lower assembly labor in electroacoustic transducers.

A magnetic-potential loudspeaker diaphragm integrates a rigidity adjusting portion with a magnetic conductive material to drive sound generation.

An elastomeric ring rolls on the radiator and basket surfaces to extend excursion while reducing rocking in compact loudspeakers.

Suspended spider stabilization in a multi-magnet structure increases excursion range and sound pressure without requiring larger amplifiers.

Segmented polymer film stabilizer resists asymmetric motion and limits large excursions to prevent shock-induced instability.

A piezoelectric film with a polymer composite featuring a void volume ratio of 1.2 or greater across its thickness.

Thermal molding nests the membrane onto the carrier ring, eliminating gluing steps and reducing environmental pollution.

Segmented edge unit with first and second edges suppresses division resonance, maintaining linearity and reducing distortion.

A two-step damper structure and flat vibration plate increase voice coil diameter to boost sound pressure in ultra-thin speaker units.

Offset inner ring magnets in a loudspeaker assembly create a compensated magnetic field that minimizes eddy currents and reduces non-linearity distortions.

Segmented elastic arms with varying thickness distribute applied force to reduce root stress and prevent mechanical fatigue breakage.

Filling the air gap with ferrofluid confines the magnetic field and seals the membrane, resolving complexity trade-offs in loudspeaker design.

Nested motor and inverted spider suspension maintain diaphragm surface area to preserve low-frequency output in reduced cabinet volume.

A speaker uses a magnetic conductive element to support the coil assembly and suspension.

A rectangular locking ring secures the diaphragm edge in an acoustic device housing.

A speaker mounting member features a bending portion fixed to the connector, securing the first diaphragm and voice coil assembly.

A flat speaker uses a single permanent magnet and voice coil plates to reproduce sound frequencies.

Curved baffle structure eliminates geometrical discontinuities and diffraction products between high frequency driver and low frequency cone.

Bow-shaped damper inner circumference with wave sections reduces lowest resonance frequency while maintaining compact size.

Tapered yoke cross-section generates magnetic saturation to lower high-frequency impedance without adding non-magnetic conductive caps.

Batch stamps chuck ring inner holes and bonds vibrating diaphragms to resolve manual assembly inefficiency.

Angled integral flanges secure diaphragms on vented voice coil bobbins, resolving the trade-off between resonance control and compact axial driver size.
