A loudspeaker comprises a diaphragm, a tubular voice coil assembly coupled to the diaphragm, a magnet assembly providing an annular gap in which the tubular voice coil assembly is arranged, and a flexible suspension. A longitudinal axis of the tubular voice coil assembly extends along a central axis of the loudspeaker. A longitudinal axis of the annular gap extends along the central axis of the loudspeaker. The flexible suspension has a disc shape and is configured to guide a movement of the tubular voice coil assembly along the central axis of the loudspeaker. The flexible suspension extends substantially perpendicular to the central axis. An inner diameter of the tubular voice coil assembly is greater than or equal to an outer diameter of the flexible suspension.

The present disclosure provides a speaker, including a frame, a vibrating system and a magnet portion accommodated in the frame, the vibrating system includes a diaphragm and a voice coil which drives the diaphragm to vibrate, the diaphragm includes a first suspension at a central position of the diaphragm, a second suspension at an edge position of the diaphragm and a dome connected between the first suspension and the second suspension, an inner periphery of the first suspension is fixed on the magnet portion, an outer periphery of the first suspension is connected with the dome, an inner periphery of the second suspension is connected with the dome, an outer periphery of the second suspension is fixed on the frame, a stiffness of the first suspension is different from a stiffness of the second suspension. Comparing with the related art, the speaker of the present disclosure guarantees sounding effect.

The present disclosure provides a speaker including a frame, a vibration system, and a magnetic circuit system, wherein the vibration system includes a first vibration diaphragm and a second vibration diaphragm which are fixed to two opposite sides of the frame, the magnetic circuit system includes a bobbin, a magnet fixed in the bobbin and spaced from an inner wall of the bobbin, a first pole plate fixed on one side of the magnet close to the first vibration diaphragm, a second pole plate fixed to one side of the magnet close to the second vibration diaphragm, and a third pole plate fixed outside the bobbin and spaced from an outer wall of the bobbin. The first voice coil assembly and the second voice coil assembly move inside and outside in a staggered manner, which saves a Z-directional space of the speaker and achieves higher magnetic field efficiency.

Embodiments relate to an audio system configured to provide enhancement of low audio frequencies. The audio system includes a tissue transducer and a speaker coupled to the tissue transducer. The tissue transducer is configured to be coupled to a tissue of a user (e.g., pinna of a user's ear). The speaker includes a diaphragm having a first surface and a second surface that is opposite the first surface. The first surface is configured to generate a first set of airborne acoustic pressure waves, and the second surface is configured to generate a backpressure. The tissue transducer is driven by the backpressure to vibrate the tissue to form a second set of acoustic pressure waves. The first set of airborne acoustic pressure waves and the second set of acoustic pressure waves together form audio content that is presented to the user.

Disclosed is a micro loudspeaker, which comprises a magnetic circuit system, a vibration system and a support system. The magnetic circuit system comprises a yoke, and a magnet and a washer accommodated within the yoke. The vibration system comprises a diaphragm and a voice coil adhesively fixed to the diaphragm. The support system comprises a front cover, and a housing matched and combined with the front cover. The housing comprises a bottom wall and a side wall. The bottom wall is provided with a mounting portion accommodating the magnetic circuit system, and is also provided with an assembly plane for assembly with a terminal. A height difference is provided between a position of the bottom wall of the housing corresponding to the assembly plane and a position of the side wall of the housing corresponding to the assembly plane, so as to cooperatively form an avoidance inclined surface.
