-D/A converter is connected with described decoder, converts the digital signal that receives to audio analog signals.
Described attaching plug comprises being set to two core plugs or being set to three-prong plug.Described supply hub is set to two core jacks or three core jacks.Described audio jack is set to L channel jack and R channel jack.
The beneficial effects of the utility model mainly show: 1, can insert the power line appliance network, realize effective use of traditional analog audio amplifier; 2, volume is little, and is easy to use.
Description of drawings
Fig. 1 is the outline drawing of audio amplifier transducer;
Fig. 2 is the system construction drawing of the electronic-controlled installation of audio amplifier transducer.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1-2, a kind of audio amplifier transducer that connects power line network, comprise housing 1, be arranged on the attaching plug 2 in described housing 1 front, be arranged on the supply hub 3 at described housing 1 back side, be arranged on the analogue audio frequency jack 4 and the electronic-controlled installation that is arranged in the described housing 1 at described housing 1 back side.
Described shell 1 adopts plastic casing, and plastic material satisfies the safety insulating requirements.
Described attaching plug 2 is used to introduce power supply, can directly be inserted in the supply socket.Adopt copper material, be set to two core plugs or be set to three-prong plug, do not influence the enforcement of patent.
Described supply hub 3 is used for out-put supply, can be connected with the attaching plug of traditional analog audio amplifier.Be set to two core jacks or three core jacks, do not influence the enforcement of patent.
Described audio jack 4 output simulated audio signals can be connected with the tone frequency channel wire of traditional audio amplifier.Be set to L channel jack and R channel jack.
Described electronic-controlled installation is used for obtaining audio file from power line, and converts analog signal to and export.Comprise:
-power line network bridge joint module 5 is connected with power line, can receive the digital information on the power line.This module adopts the power line transmission technology, and the high-frequency signal of carrying information is loaded on electric current, and with the electric wire transmission, the module of receiving information is separated high-frequency signal again from electric current, and is sent to terminal, transmits with realization information then.
-processor 6 is connected with described power line network bridge joint module 5, is used for coordinating and handling various data.This device can adopt digital signal processor at a high speed, and inside is provided with the memory of storage identity identification information.When processor 6 when described power line network bridge joint module 5 obtains data, identity identification information that at first will be wherein compares with identity identification information in the memory of processor 6, if identical, just can remove to receive corresponding data.
-decoder 7 is connected with described processor 6, is used for the audio compression information that receives is decoded.In order to improve efficiency of transmission, audio-frequency information is all through overcompression, and audio compressed files is reduced through decoder 7.
