Sound production components

A sound production component, comprising:

• a diaphragm;
• a magnetic circuit assembly;
• a coil, the coil being connected to the diaphragm and at least partially disposed in a magnetic gap formed by the magnetic circuit assembly, the coil driving the diaphragm to vibrate to produce a sound after being energized;
• a housing, the housing having at least one pressure relief hole;
• and
• a bracket disposed around the magnetic circuit assembly;
• wherein:
• the bracket is provided with a plurality of air holes, a sound from a back side of the diaphragm is transmitted through the plurality of air holes to the at least one pressure relief hole,
• the plurality of air holes includes a first air hole and a second air hole, an area of the first air hole is greater than an area of the second air hole, and
• for any one of the at least one pressure relief hole, a distance between a center of the first air hole and a center of the pressure relief hole is greater than a distance between a center of the second air hole and the center of the pressure relief hole.
