Description
Technical field
The utility model relates to ear phone technology field, specially a kind of coaxial earphone loudspeaker.
Background technique
Earphone speaker used in current industrial production activities, usually coil-moving speaker.Generally by U iron, magnetic
Iron, washer, bracket, voice coil, sound film and terminal composition, its working principle is that: according to Faraday's law, when current-carrying conductor passes through magnetic
When field, an electric power will receive, direction, which meets, not carrys out bright left hand rule, and power is mutually perpendicular to electric current, magnetic direction, stress
Size is directly proportional to electric current, conductor length, magnetic flux density.When voice coil input alternation tone currents, voice coil is by an alternation
Motive force generates alternate motion, drives the vibration of sound film, pushes air and sounding repeatedly.Now, each sound channel of earphone is generally adopted
With independent one so-called " full range speaker " sounding, there is following drawback and disadvantage in fact: effective frequency bandwidth is insufficient, when adopting
When with heavy caliber earphone speaker, (such as diameter 30,40,50,55mm or more) voice coil, sound film material (get over by bore because being limited to
Greatly, quality is heavier, and speakers low frequencies cutoff frequency is lower, and high-frequency cut-off frequency is also lower), effective frequency bandwidth can only accomplish
20Hz-12kHz.When using small-bore earphone speaker, (such as diameter 26,20,10,8mm or less) is because being limited to voice coil, sound film
Equal materials (opposite bore is smaller, and quality is lighter, and speakers low frequencies cutoff frequency is higher, and high-frequency cut-off frequency is also higher), has
Effect frequency bandwidth can only accomplish 550Hz-20kHz.In fact, the frequency bandwidth of current almost all of audio signal is all
20Hz-20kHz, so an independent earphone speaker can not completely weigh audio signals all within the scope of 20Hz-20kHz
It puts.
