Durable sound amplification equipment for English teaching

Abstract

The invention provides durable sound amplification equipment for English teaching. The sound amplification equipment comprises a shell, an anti-dropping mechanism is arranged at the bottom of the inner wall of the shell, a loudspeaker body is arranged in the middle of the top of the anti-dropping mechanism; fixed strips are adhered at the tops of two sides of the loudspeaker body, a bayonet is welded at the bottom of one side, far away from the loudspeaker body, of each fixed strip, one side, far away from the loudspeaker body, of the loudspeaker body penetrates the shell and extends to the outside of the shell, and the sound amplification equipment is relates to the technical field of the audio-video equipment. Through the use of the shell, the anti-dropping mechanism, the loudspeaker body and the bayonet, the sound amplification equipment for teaching solve the problem that the service life of the sound amplification equipment is influenced since the traditional sound amplification equipment is weak in shock-resistant and anti-dropping function. The sound amplification equipment for teaching solves the problem that the service life is influenced since the sound amplification equipment for teaching is excessive in temperature after working for a long time.

Description

technical field [0001] The invention relates to the technical field of audio-visual equipment, in particular to a durable amplifying equipment for English teaching. Background technique [0002] Loudspeaker, commonly known as power amplifier or power amplifier for short, is the most basic equipment in the audio system. Its task is to amplify the weak electrical signal from the signal source (in professional audio system, it is from the mixer) to drive the speaker to make sound , which are mainly used for teaching, tour guides, outdoors, and speech activities. There are relatively small volumes that can be hung on the body, and relatively large volumes that can be carried and placed in teachers, conference halls and other places. There are many types and uses. [0003] With the continuous popularization of compulsory education and the increasing number of students accepted by various colleges and universities, when teachers are teaching, due to the large size of the classroom...
