Abstract

As shown in (figure two), gap of the equipment by bass string and guitar sound hole panel will be emitted, high pitch string is slid into from bass string inside, by default lower endIntrinsic groove gap is caught in lower end high pitch string lower position, and flicking is pressed into upper endSecondary operation arc flexible glue bar after molding (at bass string), both the transmitting equipment complete machine was embedded in sound hole (folk pop guitar sound hole normal diameter 10.3-10.5CM), adjust microphone angle, the power button of guitar and voice channel is pressed respectively, opening receiver is linked into sound console through external connecting line by receiver output audio socket or rear class words are put, and can start to realize that wirelessly convenient bullet sings transmission for capacitor pickup voice and guitar pickup.The present invention solves that industry guitar performance bullet sings the condenser type high-quality pickup voice of travel ghost power supply power supply and guitar pickup (a variety of pickup input modes) is integrally miniaturized, when not destroying former guitar construction, by the widely used micromation of high tone quality condenser type voice pickup, the integration for needing phantom power to power in recording studio, it is wirelessly transferred in conjunction with guitar pickup, sufficiently solves the problems, such as the high tone quality movement and simple equipments victory that guitar bullet is sung.

Description

Phantom power power supply capacitor formula voice and the pick-up integrated wireless transmission of guitar multiple compatibility Bullet sings equipment

Technical field: the invention mainly relates to singing for folk pop guitar bullet, belong to wireless performing device field more particularly to one Kind folk pop guitar bullet and the use equipment for singing the wireless transmission being combined as a whole, the additional mirage electricity that capacitor microphone is needed Source, capacitance sound head, capacitor microphone pre-amplification circuit constitute a miniature part entirety, annex wireless transmission and guitar pickup is wireless Transmission, collection grinding tool are integrally formed, constitute people's acoustic capacitance sound head pickup, phantom power, guitar pickup, two independently export Wireless audio frequency transmission function, built-in replaceable battery cycle charging formula, the portable embeddable taking-up of sound hole of microphone limbs fusion are miniature Integral device is integrally formed using grinding tool, the preset shape that matches with guitar sound hole, and what is then combined with flexible glue has bullet Property space and high frictional behavior be fixed on guitar sound hole, mainly will the consistent condenser type required used in high tone qualities such as recording studios The exploitation of voice pickup system sufficiently excavates the capacitor microphone for having high-frequency response characteristic and high s/n ratio at mobile wireless pickup Wireless application, the bullet that the present invention is more directed to folk pop guitar sing integration and push equipment simplification to, and voice sings wireless pickup quality sound Matter obtains the promotion of jumping characteristic.

Background technique:

Due to needing the capacitor microphone (the electret capacitor sound head of non-1.5V) of high polarization voltage, additional mirage electricity is needed Source needs specific aim to develop in volume, sings about guitar bullet, industry mesh by larger limitation, while using wireless audio frequency transmission function Preceding guitar pickup realize wireless transmission or split type 1.5V electret wear-type (the very narrow lower tone of frequency response, when performance without Method control damper head cannot reach to the distance of mouth and adjust the input volume change that voice is sung by distance, this point is to performance It is of crucial importance) the former intrinsic body amount relation of industry not yet develops in conjunction with pick-up integrated wireless of condenser type high tone quality characteristic and guitar Transmission product, universal with economic development music exempt from gradually to amplify, in addition the portable characteristics of guitar and as splendid vocal accompaniment find pleasure in Device, the present invention is flexibly convenient for the performance of folk pop guitar person of playing and singing and sound quality is promoted and is researched and developed.

Summary of the invention:

The present invention is to solve that capacitor microphone wireless transmission application, folk pop guitar is wireless, and voice pickup sound quality that bullet sings mentions It rises, utmostly optimizes simplifying for performing device, save capacitor microphone, phantom power, microphone holder, guitar pickup, wireless biography Transfer device, four main function components are concentrated as a miniature integral device, avoid plurality of devices Connection Time and equipment cost And capacitor microphone cannot achieve the situation of wireless transmission because of phantom power, General Promotion guitar bullet sings, perform succinct and with The handling maximization of machine.

Under the premise of not being transformed and destroying guitar qin body, capacitor microphone (20-20kHz) high s/n ratio, high sensitivity are utilized And the characteristic (with moving-coil, crawler type microphone) that straight wideband is rung solves the problems, such as integrated Phantom Power, and it is wireless to realize that bullet sings one High sampling rate (48KZ, CD Quality) transmission gets rid of and puts bracket and transmission line constraint outside, utmostly improves voice pickup and guitar The headend equipment of pickup quality.(as shown in figure), the frequency response of capacitance sound head is more straight much than moving-coil sound head frequency response, in figure only Substantially show two kinds of frequency response curve, different process frequency response has difference in respective curve, but form tends to little)

External tapping is arranged for guitar pickup mode in the present invention, such as shown in (figure nine), allows compatible 4 kinds of different types of masters Guitar pickup mode is wanted, the output of 1.5V supply voltage is carried, which is intended to personal preference and considers included pick up facility front end The utilization of hardware.
