Description

A kind of set a distance teaching microphone
Technical field
This utility model relates to a kind of teaching microphone, relates in particular to a kind of set a distance teaching microphone.
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 show Mostly some equipment is from stage and conference facility to develop and comes, and does not accounts for the practical situation of teachers' instruction, uses effect Really Shortcomings.Existing microphone is variation with the relative distance of teacher, and the relative position of microphone is uncertain, causes student The volume heard is change.When microphone is distant with teacher when, it may appear that volume is too small, and student can not hear clearly and gives lessons The situation of content, cannot affect the reception of sound just to population, manually makes microphone just to people under many existing microphone duties Mouthful, arm Fatigue can be caused for a long time, it is also difficult to persistently, these situations also result in teaching quality and decline.At present, much preside over Microphone holder is fixed on head by people, makes microphone just to population, and this mode can ensure that tonequality and volume, but the most little Teacher is had to adopt 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 class Hall design, attractive in appearance wireless microphone.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 can The flexible metal conduit of deformation is connected on colored ribbon, and the armoured other end connects microphone, and colored ribbon is worn over cervical region and by microphone by talker Support to the vicinity of talker's mouth, preferably dead ahead, reach the purpose amplified.Owing to flexible metal conduit can deform, make the employment can As required microphone position is carried out adjustment the most all around.When volume is too low, teacher can be by between microphone and mouth Distance be adjusted so as to smaller, when volume is excessive, the distance between microphone and mouth can be adjusted so as to larger by teacher.Due to Serpentis Leather hose has certain rigidity, and after microphone position adjusts properly, its position remains relatively unchanged over people.Therefore, it is ensured that award Class volume is suitable and keeps constant.
Flexible metal conduit is securable to bearing, it is also possible to disassemble from bearing.Bearing is securable to colored ribbon, it is also possible to from coloured silk Disassemble on band.
For the microphone of lighter weight, without rotation-preventing mechanism between flexible metal conduit end and bearing, for the microphone of heavier mass, Rotation-preventing mechanism is had between flexible metal conduit end and bearing.The microphone of heavier mass be also integrated with in addition to microphone self laser pen or other Auxiliary element.
The part that flexible metal conduit end matches with bearing hole is non-circular structure, is machined with two planes, is called big respectively 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.Anti-rotation Mechanism includes spheroid, spring, catch, is positioned at wedge shape space.Wedge shape space at least two, rotation-preventing mechanism is at least two sets, Catch is fixed in the big plane of flexible metal conduit end, and spring is fixed on the facet of flexible metal conduit end.Spring makes 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.Catch End can not contact with hole wall, and catch constitutes acute angle with flexible metal conduit end, and spheroid is positioned at the model of these acute angle both sides or its extended line Within enclosing.This mechanism 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 End turns clockwise, and two spheroids are respectively by the frictional force from bearing hole hole wall.Under the effect of frictional force, a spheroid Oriented wedge gap reduces the trend of direction motion, the trend of another spheroid oriented wedge gap augment direction motion.The former Turning clockwise of flexible metal conduit end will be hindered.In like manner, flexible metal conduit end can not rotate counterclockwise.In a word, this utility model Have the feature that
1. bearing is connected with colored ribbon and flexible metal conduit respectively, and the armoured other end connects microphone, and microphone is supported in talker The vicinity of mouth, deforms when flexible metal conduit is by staff active force, and microphone position changes with armoured deformation, and flexible metal conduit is not Do not deform during by staff active force.Flexible metal conduit is fixed on bearing, or is plugged in bearing;Flexible metal conduit end matches with bearing hole The part closed is column structure or non-circular structure, and flexible metal conduit end is that cylinder is combined or is combined by rotation-preventing mechanism with bearing hole; Bearing is fixed on colored ribbon, or has with colored ribbon and removably connect.
2. flexible metal conduit end is to be machined with two planes during non-circular structure, the biggest plane and facet, flexible metal conduit end Big one wedge shape space of formation between plane and facet and bearing hole hole wall, rotation-preventing mechanism includes spheroid, spring, catch, anti- Rotation mechanism is positioned at wedge shape space, wedge shape space at least two, and rotation-preventing mechanism is at least two sets, and catch is fixed on flexible metal conduit end End big plane on, spring is fixed on the facet of flexible metal conduit end, and spring acts on spheroid, spheroid lean against catch end, The hole wall of bearing hole, flexible metal conduit end big plane on, the end of catch does not contacts with hole wall, and catch and flexible metal conduit end are constituted 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 adjust properly After can be relatively fixed.And existing microphone volume is affected by teacher's head, arm action.Walking about of teacher also affects words The volume of cylinder.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, sound Measuring relatively low, student is difficult to not hear lecture contents.This utility model avoids the excessive too small unfavorable condition of teachers' instruction volume, has Effect prevents the fluctuation of sound.This utility model has given full play to the effect of colored ribbon, makes colored ribbon dual-use material, therefore reduces this The cost of utility model, the decoration function that colored ribbon itself is had makes this utility model better appearance.This utility model is at Periostracum Serpentis There is rotation-preventing mechanism between pipe end and bearing, microphone can be made stably to work.In a word, this utility model changes microphone solid The traditional method that human body is uncomfortable, the most attractive in appearance is caused due to head part;Overcome handheld mike or fixed microphone in classroom The fluctuations in volume that population moving causes relatively, the newest design, there is advantage attractive in appearance, comfortable, that volume is high, tonequality is good.
