Description
Technical field
The utility model belongs to sound-box device technical field, more particularly to a kind of low frequency radiation device.
Background technology
Speaker is the terminal of entire sound system, and effect is that audio electric energy is converted into corresponding acoustic energy, and its spoke
Space is mapped to go.It is the extremely important component part of sound system, because it is responsible for is transformed into acoustical signal confession electric signal
The ear of people directly listens to so key task, it will directly come into contacts with the sense of hearing of people, and the sense of hearing of people is very clever
Quick, and there is very strong resolving ability to the tone color of complex sound.Since human ear exactly evaluates the subjective feeling of sound
The most important standard of one sound system sound quality quality, accordingly, it is believed that the performance height of speaker is to a sound system
Playing quality be to play key effect.
Current speaker, plays wave Oscillation Amplitude and direction of vibration is uncontrolled, and bass effect is undesirable, some chaos.
Invention content
The purpose of this utility model is to provide a kind of low frequency radiation device the problem of being encountered for the prior art.
In order to achieve the above object, the technical solution of the utility model is：
A kind of low frequency radiation device, including frame, the frame include the upper opening being connected to up and down and under shed；In U iron from
It is lower and on be equipped with iron prop, magnet and washer successively, U iron covers the under shed, the lower part of voice coil stretch into U iron and by washer,
The top of magnet and iron prop set is wrapped up in；Frame is equipped with vibrating diaphragm, and the upper opening of frame is covered, plays wave outer edge close to shaking
Film is played and is set up in frame on the inside of wave, and frame is equipped with the positioning column with bullet wave central contact；Voice coil top is fixed with paper support,
Paper restitope is between voice coil top and vibrating diaphragm.
The edge of the vibrating diaphragm is adhesively fixed with the edge for playing wave.
The vibrating diaphragm is ball top type vibrating diaphragm.
The side-lower of frame is equipped with terminal board.
The utility model has the beneficial effects that：
1, the utility model vibrating diaphragm is designed using top dome, act as blocking high frequency, only low frequency,；The low frequency of bass extends
More preferably.
2, the utility model is affixed directly to together using the trunk edge of vibrating diaphragm with wave edge is played, can in effective space
Bullet wave is accomplished, when horn vibration, large amplitude can be produced, the bass tones for making loudspeaker send out.
3, the utility model frame center increases a positioning column, directly with bullet wave central contact, plays positioning action, loud speaker
Belong to vertical vibration in large amplitude.
4, the utility model designs through the above structure, and more dive is deep than conventional loudspeakers bass for this loud speaker bass, rich in bullet
Property, not chaos.

Specific implementation mode
A kind of embodiment of the utility model is further illustrated with reference to the accompanying drawings.
Embodiment 1：
A kind of low frequency radiation device, including frame 1, frame 1 include the upper opening being connected to up and down and under shed；In U iron under
Iron prop 2, magnet 3 and washer 4 are equipped on and successively, U iron 10 covers the under shed of frame 1, the under shed of U iron 10 and frame 1
Junction be equipped with secondary magnetic 5, the lower part of voice coil 7 is stretched into U iron 10 and wraps up in the top of washer 4, magnet 3 and iron prop 2 set；Frame
1 is equipped with vibrating diaphragm 9, and vibrating diaphragm covers the upper opening of frame 1, plays 6 outer edge of wave close to vibrating diaphragm 9, plays 6 inside of wave and be set up in frame
On 1, frame 1 is equipped with the positioning column 12 with bullet 6 central contact of wave；Frame center increase a positioning column, directly with play wave in
The heart contacts, and plays positioning action, loud speaker belongs to vertical vibration in large amplitude.7 top of voice coil is fixed with paper support 8, paper support 8
Between 7 top of voice coil and vibrating diaphragm 9.
The edge of vibrating diaphragm 9 is adhesively fixed with the edge for playing wave 6.The trunk edge of vibrating diaphragm is affixed directly to one with wave edge is played
It rises, in effective space, bullet wave can be accomplished, when horn vibration, large amplitude can be produced, the bass for making loudspeaker send out
Tone color.
Vibrating diaphragm 9 is ball top type vibrating diaphragm.
The above is not limit the technical scope of the present invention, all according to the utility model technical spirit
To any modification, equivalent variations and modification made by above embodiment, the model of the technical solution of the utility model is still fallen within
In enclosing.
