Description
Technical field
The present invention relates to vehicle-mounted horn art, more particularly to a kind of light beam porjection type electronic horn.
Background technology
Loudspeaker size is the bigger the better naturally, and bigbore bass horn can have more preferable performance in low frequency part, and he is
It can be selected among choosing.The audio amplifier manufactured with high performance loudspeaker means there is lower transient distortion and more preferable sound
Matter.The loudspeaker of common multimedia audio amplifier bass horn are mostly between 3~5 inches.The audio amplifier manufactured with high performance loudspeaker is also anticipated
Taste lower transient distortion and more preferable tonequality.
Most common electrodynamic type taper cone loudspeaker.Electrodynamic type conical horn is usual to speak cone loudspeaker in the past, although
There is many high polymer material vibrating diaphragms, metal vibration diaphragm simultaneously still based on cone in vibrating diaphragm in 2014, is called with conical horn
With regard to worthy of the name.Taper cone loudspeaker substantially by magnetic loop system (permanent magnet, stem, magnetic conductive board), vibrational system (cone,
Voice coil loudspeaker voice coil) and support auxiliary system (centring disk, frame, pad side) etc. three parts form.
1. voice coil loudspeaker voice coil：Voice coil loudspeaker voice coil is the driver element of taper cone loudspeaker, and he is to be divided two layers to be wound on paper tube with very thin copper conductor
On, tens circles, also known as coil are typically wound with, magnetic conductive core column is positioned over and is doubted with the magnetic that magnetic conductive board is formed in gap.Voice coil loudspeaker voice coil is consolidated with cone
It is scheduled on together, after acoustic current-meter signal is passed through voice coil loudspeaker voice coil, voice coil vibrations drive cone to vibrate.
2. cone：Material used in the conical diaphragm of taper cone loudspeaker has many types, typically there is natural fiber and people
Make the major class of fiber two.Natural fiber is frequently with cotton, timber, wool, spun silk etc., and staple fibre is then using artificial silk, nylon, glass
Fiber etc..Because cone is the acoustic radiating device of loudspeaker, the sound reproduction performance of loudspeaker is decide to a large extent, so
No matter any cone, it is desirable to should light rigidity again it is good, it is impossible to because environment temperature, humidity change and deform.
3. ring：Ring be for ensure axial movement of the cone along loudspeaker, limit lateral movement and set, play simultaneously
The empty effect for daring circulation before and after stop cone.The material of ring also utilizes plastics, natural rubber in addition to the material of conventional cone
Deng by being hot bonding on cone.
4. centring disk：Centring disk is used for the binding site for supporting voice coil loudspeaker voice coil and cone, ensures it vertically without crooked.It is fixed
There are many donuts in heart branch piece, voice coil loudspeaker voice coil is freely moved up and down in magnetic gap without moving laterally, ensure voice coil loudspeaker voice coil not
Collided with magnetic conductive board.Dust cover on centring disk is to prevent external dust etc. from falling magnetic gap, avoids causing dust and voice coil loudspeaker voice coil
Friction, and loudspeaker is produced abnormal sound.
