The loudspeaker has been the explanation of the equipment, mainly to amplify the speaker's voice, has reached the effect of all people can hear. But the loudspeaker will also have a more headache, that is, the impact of noise is relatively large, and the transmission of sound will not be very stable, so now gradually choose the audio guide to explain the reception. But can a audio guide really replace a megaphone? The answer is yes, because the audio guide also belongs to the transmission of audio equipment, but different from the loudspeaker, the audio guide will not have the impact of noise, because it is through the special audio transmission channel to transmit audio, rather than through the amplification of the volume to transmit, so will not let the listening people have noise trouble.
The audio guide is now in use in many occasions, such as enterprises and institutions, factories to visit customers, museums, exhibition halls to receive visitors, tourist attractions to receive tourists can see the shadow of the audio guide. In addition, there are educational training, conference speech, simultaneous interpretation of these occasions are also can use the audio guide. The audio guide also supports the use of multiple teams at the same time, it is the transmitter can be paired with multiple receivers, and at the same time, it can effectively resist the interference of the surrounding environment, in a real sense to achieve no noise to explain, explain the sound quality is also clear. So the audio guide can do the audio transmission that the loudspeaker can do, but also can do the loudspeaker can not do no noise, anti-interference.
