摘要： One or more embodiments relate to a speaker. The speaker includes a diaphragm, a magnetic circuit component, a coil, and a bracket arranged around the magnetic circuit component. At least part of the coil is arranged in a magnetic gap formed by the magnetic circuit component. The coil drives the diaphragm to vibrate to generate sound after the coil is energized. The diaphragm includes a main-body region and a folded-ring region surround the main-body region. A first part of the bracket is connected to the folded ring region. A thickness of the first part of the bracket is within a range of 0.3mm-3mm. The thickness of the first part is a minimum distance between a connection region and an attaching region. The connection region is a region where the bracket and the folded-ring region connect. The attaching region is a region where the bracket directly attaches to the magnetic circuit component in a vibration direction of the diaphragm.

摘要： One or more embodiments of the present disclosure provide a speaker. The speaker may include a diaphragm, a magnetic circuit component, a coil connected to the diaphragm, a bracket arranged around the magnetic circuit component, and a housing. At least part of the coil may be arranged in a magnetic gap formed by the magnetic circuit component, and the coil may drive the diaphragm to vibrate to generate sound after the coil is energized. The diaphragm may include a main-body region and a folded-ring region surround the main-body region. The bracket may be connected to a portion of the folded ring region away from the main-body region, and a plurality of air holes may be provided on the bracket. A pressure relief hole may be provided on the housing. Sound from a back surface of the diaphragm may be transmitted to the pressure relief hole through the plurality of air holes, and the plurality of air holes may at least include a first air hole and a second air hole. A distance from a center of the first air hole to a center of the pressure relief hole may be greater than a distance from a center of the second air hole to the center of the pressure relief hole, and an area of the first air hole may be greater than an area of the second air hole.
