Speakers, speakers, amplifiers, amplifiers, speakers

First, the concept is probably sound understanding <br> <br> including amplifiers, peripherals (including Compressor, effects, equalizers, VCD, DVD, etc.), speakers (speakers, speakers) mixer, microphone, display equipment And so on add up to one set. Among them, speakers are sound output devices, speakers, subwoofers and so on. A speaker includes three speakers, high, low, and medium, three but not necessarily three.

The amplifier is the most basic device in the audio system. The amplifier is commonly known as the "amplifier". His role is to amplify the weak signal from the sound source or preamplifier and push the speaker to sound. The function of a good sound system amplifier is indispensable.

The power amplifier is abbreviated as power amplifier. It can be said that it is the largest family in all kinds of audio equipment. Its function is mainly to amplify the weaker signal input by the audio source equipment and generate enough current to push the speaker for sound reproduction.

The microphone, scientifically known as a microphone, is an energy conversion device that converts a sound signal into an electric signal, also called a microphone, a microphone, and a microphone.

There are two types of amplifiers: wireless amplifiers and wired amplifiers. For example, teachers use it in class.

Speakers belong to the speaker, connect to the amplifier, and output sound.

Amplifier = amplifier There is no speaker in the amplifier, there is no sound; there is no amplifier in the speaker, the speaker will not sound.

The original audio is very small. To use amplifiers (loudspeakers) to amplify small audio N.. times. The average speaker is relatively large, and the audio source of a plate is very small. If the audio is directly connected to the speaker, the sound is almost inaudible, so the amplifier is used to amplify the audio signal.

Highly active against diptera, homoptera coleoptera insects and mites. Target pests include rice leaf folder, dlamondback moth, cabbage butterfly,mematodes, jumping plantlices. Application crops include rice, vegetables, fruit trees, cotton,etc.

Abamectin is also used as a Veterinary antihelmintic. Resistance to abamectin-based antihelmintics, although a growing problem, is not as common as to other classes of veterinary antihelmintics. The benzoate salt emamectin benzoate is also used as an Insecticide.
