Description
Technical field
The present invention relates to a kind of teaching microphones, relate in particular to a kind of set a distance teaching microphone.
Background technique
In modern multimedia classroom, especially up in the classroom of hundreds of people, it is necessary to have and amplify and stereo set, and show
Equipment mostly be to be evolved from stage and conference facility, do not account for the actual conditions of teachers' instruction, use effect
Fruit Shortcomings.The relative distance of existing microphone and teacher be change, the relative position of microphone be it is uncertain, cause student
The volume heard is variation.When microphone and teacher distance farther out when, it may appear that volume is too small, and student, which can not hear clearly, to give lessons
The case where content, under many existing microphone working conditions can not face population, influence the reception of sound, make microphone face people manually
Mouthful, it will lead to arm Fatigue for a long time, it is also difficult to which persistently, these situations also result in teaching quality decline.Currently, many preside over
Microphone holder is fixed on head by people, makes microphone face population, and this mode can guarantee sound quality and volume, but at present seldom
There is teacher in this way.
Summary of the invention
The purpose of the present invention: the present invention is directed to overcome above-mentioned prior art disadvantage, develop it is a kind of be newly classroom designing,
Beautiful wireless microphone.The microphone can be used for performer, host etc..
The present invention is realized using following technical approach: the present invention is using support with certain rigidity and deformable snake
Leather hose is connected on colored ribbon, and the armoured other end connects microphone, and colored ribbon is worn over neck and supports to microphone and said by talker
Near words person's mouth, preferably front, achieve the purpose that amplify.Since flexible metal conduit can deform, user can be according to need
Microphone position is subjected to adjustment up and down all around.When volume is too low, teacher can adjust the distance between microphone and mouth
Smallerly whole, when volume is excessive, the distance between microphone and mouth can be adjusted so as to larger by teacher.Since flexible metal conduit has
Certain rigidity, after microphone position adjustment is suitable, position is remained relatively unchanged over people.Therefore, it is ensured that volume of giving lessons is closed
It fits and remains unchanged.
Flexible metal conduit is securable to support, can also disassemble from support.Support is securable to colored ribbon, can also be from coloured silk
It takes and disassembles.
For the microphone of lighter weight, without rotation-preventing mechanism between snakeskin pipe end and support, for the microphone of heavier mass,
There is rotation-preventing mechanism between snakeskin pipe end and support.The microphone of heavier mass is also integrated with laser pen or other in addition to microphone itself
Auxiliary element.
The part that snakeskin pipe end is matched with bearing hole is non-circular structure, and there are two planes for processing, is called respectively big
Plane and facet.A wedge shape space is formed between the big plane and facet and bearing hole hole wall of snakeskin pipe end.Anti-rotation
Mechanism includes sphere, spring, baffle, is located in wedge shape space.Wedge shape space at least two, rotation-preventing mechanism are at least two sets,
Baffle is fixed in the big plane of snakeskin pipe end, and spring is fixed on the facet of snakeskin pipe end.Spring leans against sphere
Baffle end, the hole wall of bearing hole, snakeskin pipe end big plane on, three contact points have determined the position of sphere.Baffle
End cannot be contacted with hole wall, and baffle and snakeskin pipe end constitute acute angle, and sphere is located at the acute angle both sides or the model of its extended line
Within enclosing.The mechanism utilizes the principle anti-rotation of friction self-locking.
Below for analyzing its self-lock mechanism the case where there is two sets of rotation-preventing mechanisms.When branch dwell of sley, such as flexible metal conduit end
End rotates clockwise, and two spheres are respectively by the frictional force from bearing hole hole wall.Under the action of frictional force, a sphere
Oriented wedge gap reduces the trend of direction movement, the trend of the oriented wedge gap augment direction movement of another sphere.The former
It will hinder rotating clockwise for snakeskin pipe end.Similarly, snakeskin pipe end can not rotate counterclockwise.In short, the present invention has
Following characteristics:
1. support is connect with colored ribbon and flexible metal conduit respectively, the armoured other end connects microphone, and microphone is supported in talker
It near mouth, deforms when flexible metal conduit is by manpower active force, microphone position is changed with armoured deformation, and flexible metal conduit is not
It does not deform when by manpower active force.Flexible metal conduit is fixed on support, or is plugged in support；Snakeskin pipe end and bearing hole match
The part of conjunction is cylindrical structure or non-circular structure, and snakeskin pipe end and bearing hole is in conjunction in conjunction with cylinders or by rotation-preventing mechanism；
Support is fixed on colored ribbon, or has with colored ribbon and be detachably connected.
It is processed when 2. snakeskin pipe end is non-circular structure there are two plane, i.e., big plane and facet, snakeskin pipe end
A wedge shape space is formed between big plane and facet and bearing hole hole wall, rotation-preventing mechanism includes sphere, spring, baffle, is prevented
Rotation mechanism is located in wedge shape space, wedge shape space at least two, and rotation-preventing mechanism is at least two sets, and baffle is fixed on flexible metal conduit end
In the big plane at end, spring is fixed on the facet of snakeskin pipe end, and spring acts on sphere, sphere lean against baffle end,
On the hole wall of bearing hole, the big plane of snakeskin pipe end, the end of baffle is not contacted with hole wall, and baffle and snakeskin pipe end are constituted
Acute angle, sphere are located within the scope of the acute angle both sides or its extended line.
Beneficial effects of the present invention: the present invention makes the Azimuth & Range between microphone and population can phase after adjustment is suitable
To fixation.And existing microphone volume is influenced by teacher head, arm action.Walking about for teacher also influences the sound of microphone
Amount.What is particularly worth mentioning is that the existing microphone in part is difficult to be placed in the front of population, front can be only positioned at, volume is lower,
Student is difficult to not hear lecture contents.The invention avoids the excessive too small unfavorable conditions of teachers' instruction volume, effectively prevent sound
The fluctuation of sound.The present invention has given full play to the effect of colored ribbon, makes colored ribbon dual-use material, therefore reduces cost of the invention, color
Keep the present invention relatively beautiful with decoration function possessed by itself.The present invention has anti-favourable turn between snakeskin pipe end and support
Structure can make microphone steadily work.In short, the present invention changes and microphone is fixed on head part causes human body uncomfortable, not enough
Beautiful traditional method；Handheld mike or fixed microphone are overcome in classroom with respect to fluctuations in volume caused by population moving,
Instead new design has the advantages that beautiful, comfortable, volume is high, sound quality is good.
