摘要： 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.

摘要： The present disclosure discloses a sounding device including a frame, a magnetic circuit system with a magnetic part and a vibration system. The vibration system includes a diaphragm fixed to the frame, a voice coil driving the diaphragm to vibrate and arranged around the magnetic part, and a metal shrapnel with conductive function. One end of the metal shrapnel is fixed to the frame and electrically connected to an external circuit, and the other end of the metal shrapnel is fixed to the voice coil and electrically connected to the lead wire of the voice coil. The metal shrapnel restrains a movement of the voice coil in a direction perpendicular to a vibration direction of the diaphragm. Compared with the related art, the sounding device disclosed by the present disclosure can reduce the number of elements to simplify the product structure.

摘要： Acoustic waveguides can be used to improve audio performance of playback devices, such as a soundbar. Such a playback device can include an elongated body defining an outer perimeter with a forward surface, an upper surface, and a rounded edge between the forward surface and the upper surface. An up-firing transducer is configured to direct sound along an axis that has a vertical oblique angle with respect to a forward axis. A waveguide in fluid communication with the up-firing transducer includes a sidewall extending circumferentially around the transducer, the sidewall having a first end adjacent the up-firing transducer and a second end adjacent the outer perimeter, such that an opening defined by the sidewall has a larger area at the second end than at the first end. A rear portion of the sidewall is more steeply angled with respect to the axis than a forward portion of the sidewall.
