Abstract
The utility model discloses an ultra-high pitch loudspeaker, belonging to the field of loudspeaker, comprising a panel, a titanium acoustic membrane, a bracket, a voice coil and a magnetic loop. The panel is provided with two metallic protectors, and the protectors are arranged at the upper part of an ultra-high pitch membrane; the center hole of the panel is composed of a R1 and a R2 two circular arcs, and the R1 and the R2 two circular arcs are crossed approaching to a tangency form for being connected in smooth transition; the titanium acoustic membrane is composed of a R 5 and a R 6 two circular arcs via smooth transition, and the top part R 5 of the acoustic membrane is smaller than R 6. The ultra-high pitch loudspeaker has strong ultra-high frequency response ability in high pitch unit, and high frequency can reaches more than 40 KHz; the ultra-high pitch loudspeaker has favorable tonal quality, low distortion and the acoustic membrane in sapphire color, and the utility model is an ultra-high pitch loudspeaker with Hi-Fi suitable for various sound boxes.
Description
Technical field the utility model super high pitch loudspeaker is to belong to the loud speaker field, is the high-fidelity superelevation sound unit that is used in the high-fidelity loudspeaker system.
The background technology super high pitch loudspeaker is the development of complying with the Digital A technology, the information that the digital audio amplifier can high-fidelity amplifies 100KHZ aspect Audio Processing, and can't show the details of music hyper band as the loud speaker of the terminal plays window of sound system, give the analysis power of a whole set of sound system, telepresenc is had a greatly reduced quality, the backwardness of superelevation sound technology has become the eck of the development of sound system, super high pitch loudspeaker, be to exist voice unit hyperfrequency responding ability poor at the sound equipment field, problems such as performance is general, it is excellent that research and development hyperfrequency, high frequency can reach the above performance of 40KHz, low cost new superelevation sound unit.The high frequency response of common high pitch loudspeaker can only arrive 20KHz, and being high pitch loudspeaker frequency response and tonequality, the sound film shows one of crucial accessory, because it is bigger that the sound film is cut apart the vibration distortion at work, the big rise and fall of frequency response peak valley, tonequality is relatively poor, can't really embody music hyperfrequency information, titanium alloy complex tone film high pitch has better reputation always, and high frequency is soft inadequately, appearance color is single but also have.
The purpose of this utility model is to provide a kind of have wideband, hyperfrequency, high sensitivity, low distortion, and is good in voice unit hyperfrequency responding ability, and high frequency can reach the tweeter that the above performance of 40KHz suitable multiple audio amplifier excellent, that cost is low uses.
The content the purpose of this utility model of utility model reaches by following measure; the sound film is that high pitch loudspeaker frequency response and tonequality show one of crucial accessory; because it is bigger that the sound film is cut apart the vibration distortion at work; the big rise and fall of frequency response peak valley; improve the structure of sound film; realize the real music hyperfrequency information that embodies; titanium alloy complex tone film high pitch has better reputation always, can realize the purpose of this utility model to the improvement of titanium alloy complex tone film, and the utility model loud speaker is by panel; titanium alloy sound film; support, voice coil loudspeaker voice coil, the magnetism loop constitutes; 2 strip metal protectors are housed on the panel; protector prevents that the sound film is subjected to outer object crimp and damages above high pitch sound film, the face plate center hole is by R1; two circular arcs of R2 constitute; R1; R2 two circular arcs seamlessly transit through intersecting near tangent form connection, can improve high frequency response.The magnetism loop is made of high magnetic energy rare earth material ndfeb magnet, low magnetic resistance low-carbon alloy steel U iron, washer.Superelevation sound titanium alloy sound film is made of circular arc titanium alloy sound film and silk quality R shape ring.The silk quality ring is seamlessly transitted by two sections circular arcs of R3, R4 and forms, and R3＜R4 can improve the right positioning action of ring.The silk quality ring has certain flexibility and linear compliance, can improve the loudspeaker frequency response and answer low distortion.Titanium alloy sound film is seamlessly transitted by two sections circular arcs of R5, R6 and forms, sound film top R5 is less than R6, can improve sound film top intensity, effectively improve the hyperfrequency response of sound film, the vibration of cutting apart that suppresses the sound film reduces distortion, and titanium alloy sound film processes through special process, the surface is the sapphire color, the modulus of elasticity height, good rigidly, hyperfrequency response excellence can reach 40KHZ.
The utility model is strong in voice unit hyperfrequency responding ability, and high frequency can reach more than the 40KHz, and tonequality is good, and distortion is low, low cost, and the sapphire color is that a kind of suitable multiple audio amplifier use has the Hi-Fi tweeter.
