On any one frame of frame.The upper side frame of picture frame is provided with to be put into the slot position of picture, setting in this way, Lao Shike
Easily the picture shown will be needed to be put into picture frame by slot position；Plurality of pictures can be accommodated in picture frame, thus teacher
The picture for needing to show can be selected by way of extracting picture out, so that the replacement of exhibiting pictures can be more convenient
It is simple and fast.
Further, the audio input port is set to the outer surface of speaker.The outer surface of speaker is arranged in audio input port,
So as to easily be attached external equipment with audio input port, so that audio signal transmission is to speaker, Jin Erke
To be played out to audio signal.
Further, the outer surface of the speaker is provided with broadcast mouth.The outer surface of speaker is provided with broadcast mouth, so that
The sound that speaker plays can successfully play out transmitting, will not be stopped because of the mouth that broadcasts and the feelings that cause sound to become smaller
Condition occurs.
The beneficial effects of the utility model are: the utility model provides a kind of picture frame sound for receiving wireless microphone signal
Case, speaker are fixed on a frame side of picture frame, and speaker is combined with picture frame, saves the space in classroom, so that classroom
Environment is more beautiful；It include wireless receiving module, the signal transmitted for receiving wireless microphone inside speaker；Wirelessly connect
It receives module and the signal received is transferred to reception processor, receive processor and High frequency amplification, analog frequency mixing solution are carried out to signal
Analog audio signal is converted digital audio and video signals by reconciliation analog-to-digital conversion, and control module receives reception processor and is transmitted across
The demodulated signal come, the matching code in demodulated signal is compared with preset value；If consistent, control module sends control signal
To processor is received, then receives processor and transfer signals to audio processing modules, audio processing modules filter signal
Then wave and digital-to-analogue conversion transmit a signal to power amplifier module, analog signal is carried out signal enhanced processing by power amplifier module, and driving is raised
Sound device makes a sound, so that speaker can receive microphone signal and can play out, it is that imparting knowledge to students for teacher is wide with school
It broadcasts and provides good condition.
Detailed description of the invention
The utility model is described in further detail with example with reference to the accompanying drawing.
Fig. 1 is a kind of structure chart for the board frame sound box for receiving wireless microphone signal of the utility model；
Fig. 2 is a kind of circuit block diagram for the board frame sound box for receiving wireless microphone signal of the utility model.
Specific embodiment
Referring to Fig.1, the board frame sound box of a kind of reception wireless microphone signal of the utility model, including picture frame 1 and speaker 2,
The speaker 2 is fixed on the frame side of picture frame 1, and the speaker 2 includes wireless receiving module 3, receives processor 4, audio processing mould
