Description
Technical field
The utility model relates to a kind of broadcasting audio amplifier, especially a kind of wireless charging type broadcasting audio amplifier.
Background technology
At present, the employed sound box system of public broadcasting almost is exactly one type, wired constant-pressure type that hinders surely has the top of suction or ceiling-mounted, but nearly all is to use the cable to connect, the scheme that the audio amplifier use wireless connections of individual brand are also arranged, but have a bit, if when running into fire or other incidents and taking place, if power supply is forced to interrupt, after perhaps some circuit was destroyed, the audio amplifier of this part was with regard to cisco unity malfunction.
Summary of the invention
According to background technology, the purpose of this utility model is to avoid above-mentioned deficiency, provide one when normal the use, to connect civil power, when interrupting, civil power switches to storage battery power supply, by commercial power charged, the signal that adopts the wireless receiving custom frequencies to launch carries out the wireless charging type broadcasting audio amplifier of public address at ordinary times.
To achieve these goals, the utility model is achieved through the following technical solutions:
A kind of wireless charging type broadcasting audio amplifier, mainly by sound box (1), loud speaker (2), electronic compartment (3), ANTENN AUDIO reception antenna (4) and power line (5) are formed, and wherein: constitute sound box (1) by wood based panel, wherein the bottom is provided with diaphragm plate (11) formation electronic compartment (3); In sound box (1), loud speaker (2) is installed on the Loudspeaker panel (12), on it tweeter (21), it is intermediate frequency or woofer (22) down; 12V storage battery (31) and audio amplifier wiring board (32) are set in electronic compartment (3), and its audio amplifier wiring board (32) is by accumulator voltage detecting circuit, battery charging circuit, power supply power supply commutation circuit, the ANTENN AUDIO receiver module, audio-frequency power amplifier, the civil power input transformer constitutes; The outer top of its sound box (1) is provided with the reception antenna (4) of ANTENN AUDIO receiver module, is connected with audio amplifier wiring board (32) through dividing plate (11) by line (41), from the interior extracting power supply cord of electronic compartment (3) (5) of sound box (1).
Owing to adopt technique scheme, the utlity model has following advantage and effect:
1, the utility model has changed the loaded down with trivial details of public in the past public address audio amplifier wiring, adopt point-to-point emission to receive, setting emission and receive frequency that can be random, thereby realization sectorization broadcast, under urgent situation of constantly cutting off the electricity supply, can also utilize the storage battery of self to power, guarantee carrying out smoothly of public address broadcasting, can be used in important or special occasions such as public broadcasting and fire broadcast.
2, the utility model is simple in structure, and is cheap, and working service and repairing are simple and easy.
