Loudspeakers TRIZ Cases
- Dual-Diaphragm Loudspeaker Structure for Low Distortion Privacy
Opposed diaphragms and damping rubber blocks stabilize voice-coil motion to cut distortion, noise, and lateral sound leakage.
- Tactile Transducer DSP Control for Headphone Sound Localization
Digital filtering and closed-loop tactile control add directional cues in headphones, improving sound localization and situational awareness.
- Opposed-Voice-Coil Loudspeaker Structure for Distortion Control
Opposed voice-coil winding and dual diaphragms improve BL-curve symmetry, reducing loudspeaker distortion, noise, and call leakage.
- Single-Amplifier Speaker Circuit With Frequency Split and Anti-Phase Muffling
A single power amplifier and capacitor split low and high audio paths, simplifying portable speaker circuits while enabling anti-phase muffling.
- Vehicle Seat Speaker Phase Control for Adjustable Tactile Feedback
Opposed low-frequency seat speakers use phase-controlled input signals to vary tactile vibration independently of audio volume.
- Vehicle Seat Speaker Control for Adjustable Tactile Feedback
Opposed low-frequency seat speakers use controlled amplitude and phase to vary or cancel tactile feedback without changing audio volume.
- Tubular Magnet Speaker Driver for High-Power Low-Inductance Audio
A tubular magnet driver layout raises speaker power capacity while lowering inductance, reducing rub and buzz, and simplifying assembly.
- Flexible PCB Loudspeaker Cone for Synchronized Light and Audio
A flexible PCB on the loudspeaker diaphragm integrates lighting and control electronics to align visual effects with audio output.
- Coaxial Speaker Magnetic Layout for Reduced Height
Nested sounding units and shared magnetic elements cut coaxial speaker height and magnetic circuit cost while preserving separate gaps.
- Coaxial Speaker Shared Magnetic Gaps for Lower Height
Nested sounding units and shared magnetic gaps reduce coaxial speaker height and magnetic circuit cost while preserving sound emission.
- Loudspeaker Vibration Assembly With Phase Ball for Low Distortion
A phase ball and dual-damper loudspeaker layout corrects phase distortion while improving stability, thinness, and sound quality.
- Speaker Edge Welding With Ultrasonic Energy Director
A meltable energy director enables fast, stable ultrasonic welding of the speaker edge, avoiding solvent adhesives and improving waterproof sealing.
- Speaker Magnetic Circuit Layout for Larger Vibration Space
Segmented side magnets with projections free more vibration space while preserving magnetic force to improve speaker acoustic output.
- Speaker-Integrated Antenna Layout to Cut Vehicle Installation Labor
By placing WiFi/LTE antenna elements concentrically inside the speaker cone, vehicle installation labor and antenna-related cost are reduced.
- 3D Flexible PCB Elastic Arm Layout for Sound-Producing Units
A folded 3D flexible PCB with non-parallel elastic arms improves vibration sensitivity, avoids magnetic circuit interference, and extends service life.
- Dual-Diaphragm Sound Emitting Structure for Space-Saving Terminals
A single voice coil drives two diaphragms to emit sound on both sides, saving terminal space while improving waterproofing and diaphragm protection.
- Display-Adjacent Speaker Pairing for EMI-Canceling Audio Output
Opposite-phase electrical drive lets adjacent speakers cancel EMI near display data lines while preserving in-phase audio output in compact devices.
- Self-Sounding Display Panel Layout for Accurate In-Screen Audio
Multiple vibrating display units and sound channels improve in-screen audio positioning, listening range, and immersion in compact displays.
- Suspended Speaker Magnetic Structure for Resonance Isolation
Elastic members suspend the speaker magnetic structure to absorb reaction force, cut frame resonance, and improve sound quality.
- Multi-Voice-Coil Loudspeaker for Diaphragm Resonance Control
Independent inner and outer voice coils control radial diaphragm vibration to reduce high-frequency resonances and interference effects.
