Description
Technical field
The utility model is related to a kind of radio, is specifically a kind of experiment radio.
Background technology
Radio, is formed by the construction such as mechanical devices, electronic device, magnet, and electric wave signal is changed and can received with electric energy
A kind of machine for radio station transmitting audio signal of listening to the radio programme.Also known as radio, broadcast etc..Radio, by mechanical devices, electronics device
The construction such as part, magnet is formed, and electric wave signal is changed into a kind of machine that audio signal is launched in simultaneously energy broadcast listening radio station with electric energy.
Also known as radio, broadcast etc..The appearance of DSP technology radios, indicates that traditional analog radio will be gradually backed out the arena of history.
The digital Age of radio has arrived.
Exactly the high-frequency signal received from antenna through detection（Demodulation）Audio signal is reduced into, earphone or loudspeaker are sent to
Become sound wave.
Existing radio function is more, and structure is more complicated, is not suitable for student experimenting and uses.Do not have also in the market
There is the radio for student experimenting.
The content of the invention
The purpose of this utility model is to provide a kind of experiment radio, with asking for solving to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme：
A kind of experiment radio, including shell and base, the base are located at below shell, lead between base and shell

Cap screw is fixedly connected with shell；It is located on shell at the position above loudspeaker and offers the hole that amplifies；In shell inside front ends
Portion is provided with PCB components, and the PCB components are connected by the positive and negative terminal of wire and battery compartment；PCB components include PCB
Circuit board and FM antennas, FM antennas stretch out shell；The shell tail end is installed with AM aerial rods by AM antenna fixing seats；
The middle side part of shell one is provided with switch；Fm dial is installed in the middle part of case nose.
It is used as further program of the utility model：The shell is rigid plastics material.
It is used as the utility model further scheme：The base is rigid plastics material.
It is used as the utility model further scheme：Paster is pasted with the shell.
It is used as the utility model further scheme：Scale is printed with the paster.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in construction, reasonable in design, whole
Body causes to use racecar design, interesting strong, it is possible to increase the learning interest and manipulative ability of student, helps student deeply to understand
Class offerings；It is with low cost, it is adapted to large-scale use and popularization；With two kinds of HF modes of AM and FM, major part can be listened to
Broadcast.
