Abstract
The utility model discloses a kind of radio sound amplifier, this radio sound amplifier comprises base, sound hangs device, candle, described sound hangs device and candle is positioned on base, described sound hangs device and comprises again audio amplifier, is positioned at transparent organic pipe above audio amplifier, being provided with in described transparent organic pipe can the bead of upper and lower motion, in described audio amplifier, bottom is provided with power amplifier, is provided with the energy collector of a toroidal above described power amplifier.Owing to adopting said structure, energy-producing experiment the demonstration radio of dramatic can be amplified in classroom, make student better accept knowledge.
Description
Technical field
The utility model belongs to technical field of radio, particularly a kind of radio sound amplifier.
Background technology
At present, classroom teaching, lacks sound and amplifies energy-producing demonstration device by radio, so this experiment of demonstration that student can not be directly perceived, lively.
Summary of the invention
The purpose of this utility model is to provide a kind of demonstrating sound that can be directly perceived, lively and amplifies energy-producing demonstration device by radio.
The purpose of this utility model is achieved through the following technical solutions, this radio sound amplifier comprises base, sound hangs device, candle, described sound hangs device and candle is positioned on base, described sound hangs device and comprises again audio amplifier, is positioned at transparent organic pipe above audio amplifier, being provided with in described transparent organic pipe can the bead of upper and lower motion, in described audio amplifier, bottom is provided with power amplifier, is provided with the energy collector of a toroidal above described power amplifier.
During demonstration, the power switch opening wireless microphone and power amplifier respectively makes two equipment communicate, wireless microphone is blown with mouth, the air-flow sent from loudspeaker after sound passes to and is exaggerated in power amplifier passes through energy collector, bead in transparent pipe is hanged, sound can also be hanged device to take off audio amplifier to keep flat and make energy collector mouth facing to the candle of combustion baked, candle be extinguished, also the flash disk jack having the flash disk of music to insert power amplifier can be made the sound of music that the bead in transparent pipe has been suspended and the candle of extinguish combustion.
The beneficial effects of the utility model: the demonstration radio of dramatic can amplify energy-producing experiment on classroom, make student better accept knowledge.
