Screen, also can be automatically adjusted acoustics volume and the startup of sound equipment and closedown.
2, sound equipment collection has wireless communication unit, and user can remotely operate and sound equipment is pushed music.
3, the detection front end of infrared sensor arranges filter, and the infrared ray that human body is sent to surrounding can be collected by filter
Detection front end at infrared sensor.It can greatly strengthen infrared sensor detection human infrared signal ability, this from
Side also improves functional reliability and the susceptiveness of intelligent sound.
Accompanying drawing explanation
Fig. 1 is the intelligent sound structural representation of the present embodiment.
Detailed description of the invention
Below with reference to accompanying drawing 1, the present invention is described further, but should not limit the protection model of the present invention with this
Enclose.For convenience of explanation and understand that the noun of locality that technical scheme, following description are used all is shown with accompanying drawing
Orientation be as the criterion.
As it is shown in figure 1, the intelligent sound of the present embodiment includes infrared sensor, infrared signal amplifying circuit, central signal
Processing module and audio-frequency signal processing module.The outfan of infrared sensor and the input of infrared signal amplifying circuit are even
Connecing, the outfan of infrared signal amplifying circuit and the input of central signal processing module connect, central signal processing module
Outfan and audio-frequency signal processing module input connect.
The detection front end of infrared sensor arranges filter, and filter is hemispherical plastic lens, and filter also can use other
The filter of shape and structure, investigate in the detection front end of the employing infrared sensor to be combined of shape, it will be appreciated that any knot of filter
The selection of structure both falls within this design protection domain.Filter has the breach of storage infrared sensor detection front end.Filter can
Human body is collected in the infrared ray that surrounding is sent the detection front end of infrared sensor.Arranging filter, it can greatly increase
The ability of strong infrared sensor detection human infrared signal, this also improves the functional reliability of intelligent sound and sensitive from side
Property.
Infrared sensor uses human body pyroelectricity infrared sensor, and human body pyroelectricity infrared sensing can detect human-body emitting
10 μm about infrared ray.Human body has constant body temperature, is normally 37 degree, and therefore people knows from experience 10 μm sending specific wavelength
The infrared ray of left and right.When human body is near sound equipment, the change that infrared sensor occurs according to human infrared radiation temperature is outwards released
Electric discharge lotus, i.e. forms signal code.The infrared sensor of the present embodiment can detect the human body institute within distance sound equipment 10 meters
The infrared signal of radiation.
Infrared signal amplifying circuit uses operational amplification circuit, and owing to operational amplification circuit has high internal resistance, deep negative is anti-
Feedback, carry load capacity strong, by advantages such as load effect are little, therefore both stable from the signal that infrared signal amplifying circuit spreads out of,
Error is the most minimum.The current signal that infrared sensor is formed is too small, needs infrared signal amplifying circuit to be amplified by this current signal,
To make the convenient follow-up central processing unit of signal process.
