Description
Technical field
This utility model relates to a kind of teaching or the microphone of host, relates in particular to one and gives lessons volume adjusting instrument.
Background technology
In the classroom in modern multimedia classroom, the most up to hundreds of people, it is necessary to possess and amplify and stereo set, and existing
Mostly equipment is from stage and conference facility to develop and comes, and does not accounts for the practical situation of teachers' instruction, and using effect exists
Not enough.Existing microphone is variation with the relative distance of teacher, and the relative position of microphone is uncertain, causes student to hear
Volume is change.When microphone and teacher are distant when, it may appear that volume is too small, student can not hear clearly lecture contents
Situation, cannot affect the reception of sound just to population under many existing microphone duties, manually makes microphone just to population, long
Time can cause arm Fatigue, it is also difficult to persistently, and these situations also result in teaching quality and decline.At present, many hosts will
Microphone holder is fixed on head, makes microphone just to population, and this mode can ensure that tonequality and volume, but seldom has religion at present
Teacher adopts in this way.
Summary of the invention
The purpose of this utility model: this utility model is intended to overcome above-mentioned prior art shortcoming, develops a kind of new for classroom designing
, wireless microphone attractive in appearance.This microphone can be used for performer, host etc..
This utility model uses following technical approach to realize: this utility model uses bearing having certain rigidity and deformable
Flexible metal conduit is connected on necklace, and the armoured other end connects microphone, and necklace is worn over cervical region and supports to say by microphone by talker
The vicinity of words person's mouth, preferably dead ahead, reach the purpose amplified.Owing to flexible metal conduit can deform, make the employment can be according to need
Microphone position is carried out adjustment the most all around.When volume is too low, the distance between microphone and mouth can be adjusted by teacher
Obtaining smaller, when volume is excessive, the distance between microphone and mouth can be adjusted so as to larger by teacher.Owing to flexible metal conduit has one
Fixed rigidity, after microphone position adjusts properly, its position remains relatively unchanged over people.Therefore, it is ensured that volume of giving lessons is suitable
And keep constant.
Flexible metal conduit is securable to bearing, it is also possible to disassemble from bearing.Bearing is securable to necklace, it is also possible to from necklace
Disassemble.
For the microphone of lighter weight, without rotation-preventing mechanism between flexible metal conduit end and bearing, for the microphone of heavier mass, Periostracum Serpentis
Rotation-preventing mechanism is had between pipe end and bearing.The microphone of heavier mass is also integrated with laser pen or other auxiliary unit in addition to microphone self
Part.
The part that flexible metal conduit end matches with bearing hole is non-circular structure, is machined with two planes, be called respectively big plane and
Facet.A wedge shape space is formed between the big plane of flexible metal conduit end and facet and bearing hole hole wall.Rotation-preventing mechanism includes
Spheroid, spring, catch, be positioned at wedge shape space.Wedge shape space at least two, rotation-preventing mechanism is at least two sets, and catch is solid
Being scheduled in the big plane of flexible metal conduit end, spring is fixed on the facet of flexible metal conduit end.Spring make spheroid lean against catch end,
The hole wall of bearing hole, flexible metal conduit end big plane on, three contact points determine the position of spheroid.The end of catch and hole wall
Can not contact, catch constitutes acute angle with flexible metal conduit end, and spheroid is positioned within the scope of these acute angle both sides or its extended line.This machine
Structure utilizes the principle anti-rotation of friction self-locking.
Below for its self-lock mechanism of situation analysis with two set rotation-preventing mechanisms.When propping up dwell of sley, such as flexible metal conduit end up time
Pin rotates, and two spheroids are respectively by the frictional force from bearing hole hole wall.Under the effect of frictional force, an oriented wedge of spheroid
The trend of reduction direction, shape gap motion, the trend of another spheroid oriented wedge gap augment direction motion.The former will hinder Serpentis
Turning clockwise of leather hose end.In like manner, flexible metal conduit end can not rotate counterclockwise.In a word, this utility model has following
Feature:
1. bearing is connected with necklace and flexible metal conduit respectively, and the armoured other end connects microphone, and microphone is supported in the attached of talker's mouth
Closely, deforming when flexible metal conduit is by staff active force, microphone position changes with armoured deformation, and flexible metal conduit is not by staff
Do not deform during active force.Flexible metal conduit is fixed on bearing, or is plugged in bearing；The portion that flexible metal conduit end matches with bearing hole
Being divided into column structure or non-circular structure, flexible metal conduit end is that cylinder is combined or is combined by rotation-preventing mechanism with bearing hole；Bearing is fixed
In necklace, or have with necklace and removably connect.
2. flexible metal conduit end is to be machined with two planes during non-circular structure, the biggest plane and facet, the big plane of flexible metal conduit end
And between facet and bearing hole hole wall, forming a wedge shape space, rotation-preventing mechanism includes spheroid, spring, catch, rotation-preventing mechanism
Being positioned at wedge shape space, wedge shape space at least two, rotation-preventing mechanism is at least two sets, and catch is fixed on the big of flexible metal conduit end
In plane, spring is fixed on the facet of flexible metal conduit end, and spring acts on spheroid, and spheroid leans against catch end, bearing hole
Hole wall, flexible metal conduit end big plane on, the end of catch does not contacts with hole wall, and catch and flexible metal conduit end constitute acute angle,
Spheroid is positioned within the scope of these acute angle both sides or its extended line.
The beneficial effects of the utility model: this utility model makes the Azimuth & Range between microphone and population permissible after adjusting properly
It is relatively fixed.And existing microphone volume is affected by teacher's head, arm action.Walking about of teacher also affects the sound of microphone
Amount.What is particularly worth mentioning is that, the existing microphone of part is difficult to be placed in the dead ahead of population, can be only positioned at front, and volume is relatively low,
Student is difficult to not hear lecture contents.This utility model avoids the excessive too small unfavorable condition of teachers' instruction volume, effectively prevent
The fluctuation of sound.This utility model has given full play to the effect of necklace, makes necklace dual-use material, therefore reduces this utility model
Cost, the decoration function that necklace itself is had makes this utility model better appearance.This utility model is at flexible metal conduit end and props up
There is rotation-preventing mechanism between Zuo, microphone can be made stably to work.In a word, this utility model changes and microphone is fixed on head part
Cause the traditional method that human body is uncomfortable, the most attractive in appearance；Overcome in classroom handheld mike or fixed microphone relative to population moving
The fluctuations in volume caused, the newest design, there is advantage attractive in appearance, comfortable, that volume is high, tonequality is good.
