An asymmetrical waveguide focuses loudspeaker output toward vehicle occupants while limiting sound dispersion into unnecessary areas.
A nested sound-outlet ramp enlarges the front cavity and acoustic channel path to reduce eddy currents without adding device thickness.
Magnetic coupling and a perforated mounting ring let audio grills detach easily, supporting interchangeable designs without complex fastening.
Multiple speaker frequency ranges create acoustic resonance that moves water and foreign substances out of an electronic device’s audio passage.
An internal acoustic barrier separates speaker and microphone spaces in a protective cover to prevent vibration-driven audio interference.
Mounting the flexible circuit board on the diaphragm keeps it out of magnetic-circuit space, supporting driving force and acoustic performance.
Segmented audio channels let order takers switch a portable communicator between drive-through lanes for clearer customer ordering.
Blocking members keep sound from entering the cover-panel gap, reducing reflected interference in slim speaker housings.
Stacked sheet-metal layers thicken the assembly ring without shrinking the avoiding cavity, supporting sounder strength and sound production.
A dedicated sound pickup channel separates microphone input from speaker output to improve noise cancellation in semi-in-ear earphones.
