For the carry-on audio-visual entertainment equipment of background technique using extensively in life, earphone is then carry-on audio-visual entertainment equipment
One of important accessory.The existing single vibrating diaphragm earphone sound quality of tradition ear that is poor, and being designed in patent of invention CN201210498107.4
Machine, in the presence of structure is complicated, frequency dividing difficulty is high, the high problem of cost.And take it as a whole, for the passive vibrating diaphragm technology of master
The research of earphone is also less, influences the development of Chinese sound equipment industry, has to the research and development of the passive vibrating diaphragm technology earphone of master
Meaning.
The summary of the invention present invention provides the earphone for coaxially leading passive vibrating diaphragm technology, can carry out high-fidelity to audio signal
Playback has many advantages, such as that frequency response range is wide, sound channel harmonic distortion is small.
The present invention solves the above problems used technical solution are as follows:
Coaxially lead the earphone of passive vibrating diaphragm technology, mainly by leading note ante-chamber, active diaphragm element, passive diaphragm element, return
Sound back cavity and audio wire rod composition.
Mainly sound conduit (1) forms leading note ante-chamber by metal front cavity (2) and out;Active diaphragm element is by active vibrating diaphragm
(3), electromagnetic coil (11), unit front cover (13) and unit rear cover cabinet joint (12) form, equal with circumference on unit front cover (13)
The circular hole of even distribution is cover sound outlet hole (14), and circular hole is audio wiring hole (10), unit front cover on unit rear cover cabinet joint (12)
(13) Nian Jie by adhesive with unit rear cover cabinet joint (12), unit rear cover cabinet joint (12) and electromagnetic coil (11) are viscous by adhesive
It connects, electromagnetic coil (11) centre bore is that bass is let out sound hole (9), and active diaphragm element and metal front cavity (2) are viscous by adhesive
It connects;Passive diaphragm element is made of passive vibrating diaphragm frame (4) and passive vibrating diaphragm (8), and passive vibrating diaphragm (8) and passive vibrating diaphragm frame (4) are logical
Adhesive bonding is crossed, passive vibrating diaphragm (8) is located at passive vibrating diaphragm frame (4) center;Echo back cavity is by wooden rear chamber (5) and wire rod tail
(6) composition is managed, wooden rear chamber (5) is Nian Jie by adhesive with wire rod tail pipe (6), and wooden rear chamber (5) centre bore is rear portion
Air hole (7), wooden rear chamber (5) is Nian Jie by adhesive with passive vibrating diaphragm frame (4), metal front cavity (2) and wooden back cavity
Body (5) is bonded by adhesive;Audio wire rod is connected by wire rod tail pipe (6) and audio wiring hole (10) and electromagnetic coil (11)
It connects.
Leading note ante-chamber, active diaphragm element, passive diaphragm element, echo back cavity are located on same central axes.
Compared with prior art, innovation of the invention is:
1. novel active diaphragm element, the electromagnetic force generated in electromagnetic coil when playing audio by audio electrical signal
Sounding is driven, low-frequency sound wave is rearward revealed using electromagnetic coil mesoporous, so that active vibrating diaphragm is reduced echo resonance, but also have
Physics sound wave is from division function.
2. novel coaxial double cellular constructions are used, low-frequency sound wave and the same phase of initial sonic waves after reflection, distortion
It is small.
3. using passive bass unit, active vibrating diaphragm is revealed most of low-frequency sound wave backward in quilt when playing music
Dynamic vibrating diaphragm, passive vibrating diaphragm are driven, and are carried out low-frequency sound wave amplification, are reflected back on same axis.

Specific embodiment is described in further detail working principle of the present invention below in conjunction with attached drawing:
A kind of passive vibrating diaphragm earphone of coaxial master, mainly by leading note ante-chamber, active diaphragm element, passive diaphragm element, echo
Back cavity and audio wire rod composition.
Wherein, mainly sound conduit (1) forms leading note ante-chamber by metal front cavity (2) and out, and active diaphragm element is by actively
Vibrating diaphragm (3), electromagnetic coil (11), unit front cover (13) and unit rear cover cabinet joint (12) composition, passive diaphragm element is by passively shaking
Film frame (4) and passive vibrating diaphragm (8) composition, echo back cavity are made of wooden rear chamber (5) and wire rod tail pipe (6).
Audio wire rod passes through wire rod tail pipe (6), passes through the audio wiring hole (10) and electromagnetic coil on active diaphragm element
(11) it is connected.When playing audio, wire rod conducts audio electrical signal to electromagnetic coil (11), and electromagnetic coil (11) generates corresponding
Electromagnetic force, electromagnetism power drive active vibrating diaphragm (3) vibration issues corresponding sound wave, and wherein medium-high frequency sound wave is by before unit
