Technical field
The present invention relates to a kind of teaching microphone, relate in particular to a kind of set a distance teaching microphone.
Background technology
In modern multimedia classroom, especially reach in the classroom of hundreds of people, must possess and amplify and stereo set, and mostly existing equipment is to develop from stage and conference facility and comes, do not consider the actual conditions of teachers' instruction, result of use Shortcomings.The relative distance of existing microphone and teacher changes, and the relative position of microphone is uncertain, and the volume causing student to hear is change.When microphone and teacher distant time, there will be volume too small, student can not hear clearly the situation of lecture contents, cannot just to population under many existing microphone operating states, affect the reception of sound, manually make microphone just to population, arm can be caused for a long time tired, also it is lasting to be difficult to, and these situations also can cause teaching quality to decline.At present, microphone holder is fixed on head by many hosts, makes microphone just to population, and this mode can ensure tonequality and volume, but there be limited evidence currently of has teacher to adopt in this way.
Summary of the invention
Object of the present invention: the present invention is intended to overcome above-mentioned prior art shortcoming, develop a kind of newly be classroom designing, attractive in appearance wireless microphone.This microphone also may be used for performer, host etc.
The present invention adopts following technical approach to realize: the present invention uses bearing handle to have certain rigidity and deformable flexible metal conduit is connected on colored ribbon, the armoured other end connects microphone, colored ribbon is worn over neck and is supported to by microphone near talker's mouth by talker, preferably dead ahead, reaches the object amplified.Because flexible metal conduit can be out of shape, microphone position can be carried out adjustment all around up and down by end user as required.When volume is too low, the distance between microphone and mouth can adjust smaller by teacher, and when volume is excessive, the distance between microphone and mouth can adjust larger by teacher.Because flexible metal conduit has certain rigidity, after microphone position adjustment is suitable, its position and people keep relative constant.Therefore, the volume that can ensure to give lessons is suitable and remain unchanged.
Flexible metal conduit can be fixed on bearing, also can disassemble from bearing.Bearing can be fixed on colored ribbon, also can disassemble from colored ribbon.
For the microphone of lighter weight, without rotation-preventing mechanism between flexible metal conduit end and bearing, for the microphone of heavier mass, between flexible metal conduit end and bearing, there is rotation-preventing mechanism.The microphone of heavier mass is also integrated with laser pen or other auxiliary element except microphone self.
The part that flexible metal conduit end matches with bearing hole is non-circular structure, is processed with two planes, is called large plane and facet respectively.The large plane of flexible metal conduit end and form a wedge shape space between facet and bearing hole hole wall.Rotation-preventing mechanism comprises spheroid, spring, catch, is positioned at wedge shape space.Wedge shape space is at least two, and rotation-preventing mechanism is at least two covers, and catch is fixed in the large plane of flexible metal conduit end, and spring is fixed on the facet of flexible metal conduit end.Spring makes spheroid lean against in the large plane of catch end, the hole wall of bearing hole, flexible metal conduit end, and three contact points determine the position of spheroid.The end of catch can not contact with hole wall, and catch and flexible metal conduit end form acute angle, within spheroid is positioned at the scope of these acute angle both sides or its extended line.This mechanism utilizes the principle anti-rotation of friction self-locking.
Below for its self-lock mechanism of situation analysis with two cover rotation-preventing mechanisms.When dwell of sley, as flexible metal conduit end turns clockwise, two spheroids are subject to the frictional force from bearing hole hole wall respectively.Under the effect of frictional force, an oriented wedge gap of spheroid reduces the trend of direction motion, the trend of the oriented wedge gap augment direction motion of another spheroid.The former will hinder turning clockwise of flexible metal conduit end.In like manner, flexible metal conduit end can not be rotated counterclockwise.In a word, the present invention has following characteristics:
1. bearing is connected with colored ribbon and flexible metal conduit respectively, the armoured other end connects microphone, and microphone is supported near talker's mouth, deforms when flexible metal conduit is subject to staff active force, microphone position changes with armoured distortion, and flexible metal conduit does not deform by during staff active force.Flexible metal conduit is fixed on bearing, or is plugged in bearing; The part that flexible metal conduit end matches with bearing hole is column structure or non-circular structure, and flexible metal conduit end and bearing hole are that cylinder is combined or is combined by rotation-preventing mechanism; Bearing is fixed on colored ribbon, or has with colored ribbon and removably connect.
2. when flexible metal conduit end is non-circular structure, be processed with two planes, i.e. large plane and facet, the large plane of flexible metal conduit end and form a wedge shape space between facet and bearing hole hole wall, rotation-preventing mechanism comprises spheroid, spring, catch, rotation-preventing mechanism is positioned at wedge shape space, wedge shape space is at least two, rotation-preventing mechanism is at least two covers, catch is fixed in the large plane of flexible metal conduit end, spring is fixed on the facet of flexible metal conduit end, spring action is in spheroid, spheroid leans against catch end, the hole wall of bearing hole, in the large plane of flexible metal conduit end, the end of catch does not contact with hole wall, catch and flexible metal conduit end form acute angle, within spheroid is positioned at the scope of these acute angle both sides or its extended line.
Beneficial effect of the present invention: the present invention make the Azimuth & Range between microphone with population adjustment suitable after can be relative fixing.And existing microphone volume is subject to the impact of teacher's head, arm action.Walking about of teacher also affects the volume of microphone.What is particularly worth mentioning is that, the existing microphone of part is difficult to the dead ahead being placed in population, and can only be positioned at front, volume is lower, and student is difficult to not hear lecture contents.Present invention, avoiding the excessive too small unfavorable condition of teachers' instruction volume, effectively prevent the fluctuation of sound.The present invention has given full play to the effect of colored ribbon, makes colored ribbon dual-use material, and because this reducing cost of the present invention, the decoration function that colored ribbon itself has makes better appearance of the present invention.The present invention has rotation-preventing mechanism between flexible metal conduit end and bearing, and microphone can be made stably to work.In a word, the present invention changes traditional method microphone being fixed on head part and causing human body uncomfortable, attractive in appearance not; Overcome the fluctuations in volume that in classroom, handheld mike or the relative population moving of fixed microphone cause, replace new design, there is attractive in appearance, comfortable, that volume is high, tonequality is good advantage.
