Brief description
Fig. 1 is the external form schematic diagram of an embodiment of Multifunctional demonstration device of the present utility model；
Fig. 2 is the construction module schematic diagram of an embodiment of Multifunctional demonstration device of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings Multifunctional demonstration device of the present utility model is described in detail.
As Fig. 1, the profile entirety of Multifunctional demonstration device of the present utility model is as a microphone, comprising: mike 10, shell
Body 20, the button 30 being revealed in housing and the expansion link 40 below housing.Wherein, there are multiple function moulds the inside of housing 20
The electronic devices and components of block, expansion link 40 partly can be extended as needed or be shortened.
As shown in Fig. 2 the inner function module of housing includes: wireless midair mouse module a, audio input output module b,
Laser pointer module c, wireless communication module d, recording module e, identification people sound module f, infrared ray sensing module g and control module h.
Control module h connects above-mentioned other functions module, for controlling or coordinating other functions module.Control module h includes shell
The button 30 of body.
Wireless midair mouse module a includes acceleration transducer and gyro sensor, and acceleration transducer, gyroscope pass
The angular velocity of the inertia device Measuring Object such as sensor motion and linear acceleration, obtain position and the attitude of object by integration.
Such as, when gyroscope ultimate principle is to rotate with objects at high speed, powerful angular momentum makes rotary shaft stably point to one always
The property in direction.When the direction of motion points to inconsistent with rotating shaft, corresponding drift angle can be produced, further according to the pass of drift angle and motion
System, obtains movement locus and the position of moving object up till now, thus realizing the function of positioning.And acceleration transducer technology is
Inertia and the combination of power, by Real-time Collection moving object acceleration signal, obtain the rail moving by way of Second Order Integral
Mark is to realize positioning.Typically, gyro sensor technology and acceleration transducer technology are combined, can be reliably real
Now accurate, stable space orientation.
Audio input output module b includes Audio Input Modules and dio Output Modules.Audio Input Modules include Mike
Wind 10, amplifier circuit unit, filter circuit unit.Mike is used for collecting sound, and is converted into audio signal；Amplifying circuit list
Unit is for carrying out signal processing and amplifying to audio signal；Filter circuit unit is used for the audio frequency letter after signal processing and amplifying
Number it is filtered processing.Dio Output Modules include power amplifier unit and speaker.Power amplifier unit is used for output
Sound source data is amplified processing, with drive the speaker sounding.Recording module f, for the acoustical signal that will collect, and by no
Line communication module is transferred to multimedia computer, is stored by multimedia computer, reaches the purpose of record sound.
The opening and closing of laser pointer module c, are controlled by being revealed in the button 30 of housing, are easy to use, laser
The direction of the launch could be arranged to become vertical direction with the main body of microphone；When pressing certain button, laser pointer module sends bright
Light, when pressing this button again, laser shutdown.Use for aspect, button also include ppt can be carried out page turning on turn over work(
Can button and under turn over function button, also include being equivalent to the button of left mouse button, right mouse button.
Wireless communication module d, for the signal of control module is sent to multimedia computer, is entered with multimedia computer
Row information exchanges, and among the present embodiment, wireless communication module d can adopt bluetooth communication module.
Identification people sound module f, for being distinguished the sound of speaker and environmental noise, so that the sound by speaker
Apparent expresses, and reduces or avoid the impact of environmental noise.The sound frequency that such as people can send has certain model
Enclose, the audio frequency range that most people can send is between 85hz to 1100hz；And the sound frequency that Canis familiaris L. sends typically exists
Between 40hz to 1800hz；The sound frequency that Rana nigromaculata sends is typically between 100hz to 8000hz.Identification people sound module f, to sound
Voice frequency is less than 85hz and the sound higher than 1100hz is not processed, thus avoiding noise to be amplified by microphone and affect
Speech effect.
Infrared ray sensing module g, microphone is taken suitable distance by the user for reminding microphone, if microphone with drill
Speaker away from too far away, then show warning mark (cartoon figure's figure such as showing redness, shaking the head that microphone is too far away from
Case)；If microphone is just suitable with the distance of speaker, the in running order mark of display microphone (such as shows green
Cartoon figure's smiling face's pattern).
Illustrate below application scenarios, such as speaker explains the ppt of current page, and he pushes button, laser spot
Indicate the emphasis of ppt, explained current page, needed to intercut a video, he opens wireless midair mouse module to minimize
Ppt window, and search out the associated video below file, play out, video playback is closed after finishing, and speaker uses again
Wireless midair mouse function opens ppt window to maximization.The audience on speaker side needs to put question to, and speaker is by expansion link
Elongate, such as about one meter of distance, allow audience's be aligned microphone to put question to.Whole speech sound, can arrange unlatching recording module,
Speech content is stored in the form of the audio file control module buffer area in, then by wireless communication module send to
Multimedia computer, to store.
Enumerate another application scenarios again, when speaker is among speech process, carry out significantly limb action, infrared
Line sensing module shows the warning mark that microphone is too far away from, and speaker is recognized that microphone is too remote apart from itself automatically, needs
It is held close for some and just can send sound.
The Multifunctional demonstration device that this utility model provides, has gathered wireless midair mouse module a, audio input output mould
Block b, laser pointer module c, wireless communication module d, recording module e, identification people sound module f, infrared ray sensing module g and control mould
Block h, and provide working power so that speaker does not need two handss blocked operations by battery for these modules, it is to avoid chaotic；
In operating multifunction apparatus for demonstrating, speaker can accomplish to speak or action having step, systematically carrying out so that thinking
Dimension is smooth in order.
It should be noted that above example is only in order to illustrate the technical solution of the utility model rather than to this utility model
The restriction of protection domain, although being explained in detail to this utility model with reference to preferred embodiment, the ordinary skill people of this area
Member is it should be appreciated that can modify to the technical solution of the utility model or equivalent, without deviating from this utility model
