Description
Technical field
The utility model relates to the transaudient field of electrophone, especially relates to a kind of rotary large power, electrically musical instrument emitter.
Background technology
Electrophone emitter is widely used in the concert equipments such as electric guitar, bass and electronic violin, by CANNON plug is inserted electrophone source of sound output interface, and by emitting antenna, audio-frequency information is launched, realize the technical requirement of electrophone source information radio microphone.But in daily performance place, the CANNON plug of the electrophone emitter that user uses is designed to fixing horizontal structure more, residing for each electrophone audio output interface, external structure is different, traditional horizontal structure CANNON plug fails to be applicable to diversity electrophone audio output interface environment, each electrophone external structure is often caused to hinder electrophone emitter Cannon to insert, or affect CANNON plug insertion depth, directly affects electrophone output audio quality.The antenna of traditional electrical musical instrument emitter simultaneously, many designs adopt vertical antenna, all certain defect is there is in vertical antenna in emissive power, the electromagnetic interference (EMI) degree accepted under sensitivity and particular surroundings, often affect the on-the-spot moving range of electrophone, if play distance more than 30m, then will produce the phenomenons such as transaudient intermittent or tonequality is unintelligible.Therefore need to solve traditional electrical musical instrument emitter CANNON plug inserted mode dumb, easily by problem that electrophone structure hinders, meet the requirement of large-scale electrophone performance to signal transmission power, transmitting range simultaneously, a kind of CANNON plug inserted mode that to change flexibly according to the different contour structures of electrophone is provided, and can effectively accepts at 50m the Novel electric musical instrument emitter realizing stabilization signal transmission in scope.
Summary of the invention
The purpose of this utility model is to provide a kind of rotary large power, electrically musical instrument emitter, by designing large circular saw-tooth ring and small circular saw-tooth ring respectively at rotary switch and CANNON plug right-hand member, utilize both large circular saw-tooth ring and small circular saw-tooth ring degree of depth bonding structure and its rotatability simultaneously, solve the problem that electrophone emitter can not change CANNON plug inserted mode flexibly, improve the scope of application of electrophone emitter.By at whip antenna medium design one diameter 5cm helical ring, gain 7dBi, power capacity reaches 100w, improves electrophone emitter transmitting range, meets large-scale electrophone and plays requirement to displacement and audio transmission quality.
Technical solution of the present utility model is: a kind of rotary large power, electrically musical instrument emitter, comprise CANNON plug, rotary switch, PVC housing and whip antenna, wherein CANNON plug is provided with small circular saw-tooth ring, CANNON plug is connected with rotary switch by fixed pole, rotary switch inside is provided with large circular saw-tooth ring, PVC enclosure interior is provided with radio frequency control module, and PVC surface of shell is provided with control panel, and control panel inside is provided with start button and to frequency button; PVC housing lower end is connected with whip antenna, is provided with helical ring in the middle of whip antenna.The small circular saw-tooth ring of the CANNON plug other end adopts senior PVC material, small circular saw-tooth ring diameter 635mm, and distribute 32 tiny broached-tooth designs, fits with the large circular saw-tooth ring degree of depth of rotary switch; Large circle saw-tooth ring adopts senior PVC material, diameter 1270mm, and distribute 128 tiny broached-tooth designs; When there is external structure obstruction electrophone emitter insertion CANNON plug in electrophone audio output interface, by rotating CANNON plug level angle, large circular saw-tooth ring and the laminating of small circular saw-tooth ring are rotated, and fix CANNON plug position by fixed pole, prevent CANNON plug recurring structure from offseting, make CANNON plug can revise certain angle and insert electrophone audio output interface, be suitable for the electrophone audio output interface environment of multiple different structure, improve electrophone emitter applicability.The helical ring diameter 5cm of whip antenna lower end, the number of turns is the tight phase ring of 6 circle, because helical ring is by coaxial whip antenna feed, the directivity of whip antenna depends on the diameter (D) of helical ring and the ratio D/ λ of wavelength (λ) to a great extent, as D/ λ < 0.18, helical ring has figure-eight pattern in the plane comprising the axis of screw, greatest irradiation is being had perpendicular in the plane of the axis of screw, and the directional diagram of circular symmetry is obtained in this plane, so carbon steel wire wire is circumnutated into helical ring by certain spacing, and with the sealing of fourth meals rubber tube with the unrestrained erosion of rainwater-proof, helical ring-end be connected with the whip antenna of electrophone emitter, the other end is opened a way, constitute helical ring, ensure audio signal transmission gain 7dBi, power capacity 100w, improve electrophone emitter audio transmission quality and transmission range.
The utility model has the advantage of that a kind of rotary large power, electrically musical instrument emitter is by designing large circular saw-tooth ring and small circular saw-tooth ring respectively at rotary switch and CANNON plug right-hand member, solve the problem that electrophone emitter can not change CANNON plug inserted mode flexibly, improve the scope of application of electrophone emitter.By at whip antenna medium design one diameter 5cm helical ring, realize gain effect 7dBi, power capacity reaches 100w, improves electrophone emitter transmitting range, meets large-scale electrophone and plays requirement to moving range and audio transmission quality.
