Description
Technical Field
[0001] The utility model belongs to the technical field of sound amplification devices, and in particular relates to a sound amplification device for offline education. Background Art
[0002] Loudspeakers can be divided into many types according to their size, usage and purpose, each with its own advantages. Portable loudspeakers are limited by their size and speaker, and generally have a power of only 3-8W. Wireless loudspeakers and wired loudspeakers are different in size and use. Smaller ones are suitable for teachers and tour guides, hanging around the waist, so that both hands can be used more freely, and their power is generally 3W-8W. Large ones are suitable for outdoor activities, summer camps, extracurricular speeches and other places with large traffic, and their power is 35W-95W. Lithium-ion loudspeakers are one of the types of batteries used. It solves the problem of environmental pollution caused by traditional dry batteries. It mainly uses mobile phone lithium battery technology to power the loudspeaker.
[0003] Existing offline educational loudspeakers still have some defects. Most of them have relatively single functions. When conducting educational classes, writing pens are needed to give students writing demonstrations. During the class, the writing pens may be damaged or forgotten. For this reason, we propose an offline educational loudspeaker. Utility Model Content

[0006] Preferably, a sound outlet hole is provided on the surface of the loudspeaker body, and a display is embedded on the top of the loudspeaker body.
[0007] Preferably, an antenna is provided on one side of the loudspeaker body, and a heat dissipation hole is provided on one end of the loudspeaker body.
[0008] Preferably, a heat exhaust fan is provided inside the heat dissipation hole, and two heat exhaust fans are provided.
[0009] Preferably, a charging hole is provided on one side of the loudspeaker body, and a control key is also provided on one side of the loudspeaker body.
[0010] Preferably, a dustproof net is provided on the surface of the heat dissipation hole, and the dustproof net is fixedly connected to the heat dissipation hole.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. The function of the device is enhanced by the placement slot, top plate, spring, spare pen, hand rope and card. When the writing pen is damaged or forgotten, the spare pen can be used temporarily. The hand rope and card make the loudspeaker more convenient to carry.
[0013] 2. The display function of the loudspeaker is realized through the sound outlet and display, and the power level and working status of the loudspeaker can be checked at any time. The heat dissipation function of the loudspeaker is realized through the heat dissipation holes and heat exhaust fan. When the internal temperature of the loudspeaker is too high, the heat exhaust fan is started to quickly discharge the heat inside the loudspeaker, thereby increasing the service life of the loudspeaker.
