Speaker and electronic device

A speaker, comprising:

• a speaker unit, a first housing and a second housing, an energy director is disposed on the first housing or the second housing, wherein
• raw material components of the second housing and the first housing comprise:
• a polymer composite material and a hollow sphere material;
• the polymer composite material comprises polyamide PA, a range of a mass percentage of the PA in the polymer composite material is 80-100 wt %, a range of a diameter of the hollow sphere material particle is 2-130 μm, a range of a mass percentage of the hollow sphere material in the raw material components is 10-50 wt %, and a range of a mass percentage of the polymer composite material in the raw material components is no less than 50 wt %;
• the energy director melts after being welded to connect the first housing and the second housing together, wherein an overflow groove is disposed on a side of the energy director, and the overflow groove is configured to accommodate a molten material overflowing after being melted;
• and
• the speaker unit is disposed between the first housing and the second housing, the speaker unit connects with the first housing adhesively to form a front cavity on a first side of the speaker unit, a sound outlet channel is disposed on the first housing, the front cavity is connected to the sound outlet channel, the speaker unit is configured to drive air in the front cavity to vibrate, and the air vibrating in the front cavity is directed out through the sound outlet channel;
• and
• a rear cavity is disposed on a second side of the speaker unit based on the first housing, the second housing and the speaker unit, the rear cavity is a sealed cavity.
