Abstract

The invention discloses a loudspeaker, which comprises a vibration assembly, and is characterized in that the vibration assembly comprises a voice coil; the loudspeaker further comprises a washer arranged close to the vibration assembly; a yoke support far away from the vibration assembly; a magnet arranged between the washer and the yoke bracket; a micro heat pipe which is arranged in the magnetin a penetrating manner, is filled with a refrigerant, and is provided with an evaporation end embedded into the washer and a condensation end embedded into the yoke support. When the loudspeaker works, the washer and the magnet absorb heat released by the vibration assembly and transmit the heat to the evaporation end of the micro heat pipe, a refrigerant in the micro heat pipe is vaporized and flows to the condensation end, and the yoke support absorbs the heat released by the condensation end and releases the heat outwards. Meanwhile, the invention further discloses audio equipment. According to the invention, the overall heat dissipation efficiency of the loudspeaker is improved, it is ensured that the temperature in the loudspeaker does not rise excessively, and the working stabilityof the loudspeaker is improved.

Description

technical field [0001] The invention belongs to audio equipment, in particular to a loudspeaker and an audio equipment with the loudspeaker. Background technique [0002] A dynamic speaker is an acoustic transducer that converts electrical energy into sound energy. One disadvantage of the moving coil speaker is that the conversion efficiency of sound energy is low and the conversion rate of heat energy is high, that is, more than 90% of its electric energy will be converted into heat energy. This time causes the internal temperature of the speaker to rise and there are the following risks: 1. Cause high temperature failure of the voice coil adhesive layer; 2. High temperature failure of the voice coil diaphragm adhesive; 3. High temperature demagnetization of the magnet. The consequences caused by the above high temperature will damage the speaker products, especially the dynamic speaker products currently adopt a closed structure, and the internal heat can be transferred t...
