An apparatus includes a frame and a surround element that couples a diaphragm to the frame such that the diaphragm is movable in a reciprocating manner relative to the frame. The surround element includes a half-roll element having a concave and convex apparent area. Another apparatus includes a diaphragm, a frame, and a surround element that couples the diaphragm to the frame such that the diaphragm is movable in a reciprocating manner relative to the frame. The surround element includes a half-roll element having a horizontal span and a free-length. A ratio of the horizontal span to the free-length is constant throughout the half-roll element. In an aspect, an apparatus includes a landing and a half-roll element adjacent the landing. The half-roll element includes an outer portion having a variable thickness and a transition portion located between an inner and the outer portion.

Embodiments of the present disclosure provide a sound production component including a diaphragm, a magnetic circuit assembly, a coil, and a housing. The coil is connected to the diaphragm and is at least partially disposed in a magnetic gap formed by the magnetic circuit assembly, and the coil drives the diaphragm to vibrate to produce a sound after being energized. A sound outlet is provided on an inner side surface of the housing for directing a sound generated at a front side of the diaphragm out of the housing. The diaphragm comprises a main body region and a folded-ring region surrounding the main body region, the folded-ring region comprising an arc-shaped segment and a connection segment connected to the main body region. A projection of a center of the sound outlet along a vibration direction on the diaphragm is on an inner side of the arc-shaped segment.

The present disclosure relates to an open earphone. The open earphone may include a sound production device and an ear hook including a first part and a second part connected in sequence. The first part may be hooked and arranged between an auricle and a head of a user. The second part may extend to a front lateral surface of the auricle and may be connected to the sound production device. The sound production device may be worn at a position that is near an ear canal without blocking an earhole of the user. The sound production device may be at least partially inserted into an auricular concha cavity of the user. An overlap ratio of a projection area of the sound production device on a sagittal plane to a projection area of the auricular concha cavity on the sagittal plane may be not less than 44.01%.

The present disclosure provides an open earphone, including: a sound production component including: a transducer including a diaphragm configured to generate a sound; and a housing forming a cavity used to accommodate the transducer, wherein in a wearing state, the housing is provided with a sound guiding hole on an inner side surface toward an auricle of a user for guiding a sound generated by a front side of the diaphragm out of the housing and into an ear canal, and at least two pressure relief holes are provided on one or more other side surfaces of the housing, the at least two pressure relief holes including a first pressure relief hole away from the ear canal and a second pressure relief hole near the ear canal, and a sound pressure at the first pressure relief hole being greater than a sound pressure at the second pressure relief hole.

Sound generation component, comprising: a membrane; a magnetic circuit arrangement; and a coil connected to the diaphragm and located at least partially within a magnetic gap formed by the magnetic circuit arrangement, wherein the coil, when energized, causes the diaphragm to vibrate in order to produce sound, wherein the diaphragm comprises a main area and a surround area surrounding the main area, wherein the main area comprises a first inclined segment and a first connecting segment connected to the coil, wherein the first inclined segment abuts a portion of the surround area and the first inclined segment is inclined away from the coil relative to the first connecting segment, the inclination angle of the first inclined segment relative to the first connecting segment being in the range of 5° to 30°, wherein the first connecting segment is perpendicular to the direction of vibration of the diaphragm.

A passive horn integrally formed by using liquid silicone rubber, includes a first outer casing, a second outer casing, an inner casing and an iron piece. The first outer casing includes a sealing ring, a folding ring and a vibrating membrane, and the sealing ring, the folding ring and the vibrating membrane are integrally injection molded into the first outer casing. A groove is disposed in the second outer casing, and the first outer casing is disposed in the groove. The back surface of the vibrating membrane is provided with a casing groove, which is sequentially embedded with the inner casing and the iron piece. A preparation method of a passive horn integrally formed by using liquid silicone rubber, under the condition of integrated injection molding, may improve the yield rate, ensure product quality, save assembly time and labor cost, and improve production efficiency.

Sound generation component, comprising: a membrane; a magnetic circuit arrangement; a coil connected to the diaphragm and located at least partially within a magnetic gap formed by the magnetic circuit arrangement, wherein the coil, when energized, causes the diaphragm to vibrate in order to produce sound, the diaphragm comprising a main area and a surround area; and a support surrounding the magnetic circuit arrangement, wherein a first part of the support is connected to the corrugated area, the thickness of the first part being in the range of 0.3 mm to 3 mm and defined as the minimum distance between the connection area of ​​the support with the corrugated area and an area of ​​the support directly adjacent to the magnetic circuit arrangement in the direction of vibration of the membrane.
