Description
Technical field
The utility model relates to sound-box device technical field, specially a kind of ultralow frequency vibrationproof speaker.
Background technique
The low frequency characteristic of super-bass loudspeaker box mainly has woofer decision, generates frequency vibration, woofer at work
It is mounted in speaker, air significantly shakes with bass in speaker, and the obverse and reverse of diffuser just has positive and negative two
Wave, the diffuser back side turn the backward-wave penetrated, and reflect 180 degree by cabinet and are discharged by paraphase sound hole, backward-wave phase
Position is overlapped by paraphase with the forward wave before cone to carry out circular in sound equipment, so that range is broadened, generation subwoofer frequency response is to low
Audio tweeter, which plays, helps raw fabulous effect.
But existing ultralow frequency speaker has the disadvantage in that
1, existing bass speaker design is too simple, and in sound equipment work, internal loudspeaker generates vibration, shake
After dynamic wave is transferred on speaker, speaker and ground can be made to generate biggish friction, be if things go on like this easy to make sound equipment inner body because
Vibration is scattered, and the bottom surface abrasion of speaker is more serious.
2, existing bass speaker bass sounding effect is poor.

(3) beneficial effect
The utility model provides a kind of ultralow frequency vibrationproof speaker, have it is following the utility model has the advantages that
(1) the utility model is by setting roof supporting, support baseboard and damping spring, in use, the loudspeaking in speaker
Cone vibration in device, then air is pushed by the vibration of cone, thus make a sound, it can be by vibration wave while cone vibration
It is transferred to speaker body, then is transferred to the bottom end of speaker by speaker body, damping spring can effectively absorb vibration wave at this time, thus
Weakening vibration wave significantly when being transferred to support baseboard is insufficient to allow support baseboard to generate shaking, to avoid sound equipment sheet
Body generates biggish shaking, and the bottom end of head unit and ground is also avoided to generate biggish abrasion.
(2) the utility model generates in loudspeaker by setting paraphase plate, paraphase chamber and sound hole and pushes air sending sound
After sound, the loudspeaker back side turns the backward-wave penetrated, and paraphase chamber is entered under the barrier by paraphase plate, and be finally transmitted to by sound hole
The external world, the backward-wave issued by paraphase chamber are overlapped with the forward wave to shed from loudspeaking mouth and carry out circular, and range is made to broaden, ultralow
Frequency sound sounding effect is more preferable.
