Abstract
The utility model discloses a kind of loud speaker bilayer dust cover structures, including upper strata dust cover and lower floor's dust cover, the upper strata dust cover is located at the top of lower floor's dust cover, and the upper strata dust cover is mounted in the cone basin of loud speaker, and lower floor's dust cover is mounted on the speech coil framework of loud speaker.The utility model is on the basis of original dust cover, a dust cover is added again, buffering can be played the role of by lower floor's dust cover, the air under high speed impact is avoided directly to impact upper strata dust cover, and several apertures are uniformly provided on lower floor's dust cover, air compression energy caused by high intensity moves up and down is gone out from these apertures in time, the service life of upper strata dust cover is effectively extended while flat noise abatement, current mega bass loud speaker is solved under mega bass working condition, because high intensity up and down motion causes air compression to have little time to exclude from beneath, directly impact dust cover, cause the noise that thumping is dashed forward, the technical issues of also dust cover being caused to damage.
Description
【Technical field】
The utility model is related to the technical field of loud speaker dust cover, more particularly to a kind of loud speaker bilayer dust cover knot
Structure.
【Background technology】
Loud speaker is also known as " loudspeaker ", is a kind of very common electro-acoustic transducer device, in the electronic electric equipment of sounding
It can be seen.Loud speaker is there are many type, but its basic operation principle is similar, is that one kind converts electrical signals to
The element that voice signal is reset.At present, the most widely used is dynamic speaker, it is by vibrating membrane, voice coil, permanent
The compositions such as magnet, stent.After the voice coil of loud speaker is passed through tone currents, voice coil just generates the magnetic of alternation under the action of electric current
, permanent magnet also generates the constant constant magnetic field of a size and Orientation simultaneously.It is big due to magnetic field caused by voice coil
Small and direction is constantly changing with the variation of tone currents, and the interaction in two such magnetic field makes voice coil make perpendicular to voice coil
The movement of middle current direction since voice coil is connected with vibrating membrane, so as to which vibrating membrane be driven to generate vibration, is caused by vibrating membrane vibration
The vibration of air and make a sound.When the electric current of input voice coil is bigger, the active force in magnetic field is bigger, the width of vibrating membrane vibration
Degree is also bigger, and sound is then louder.
Dust cover is usually set on loud speaker, in order to dust-proof and protect speaker.For mega bass loud speaker, super
Under supper bass working condition, because high intensity up and down motion causes air compression to have little time to exclude from beneath, directly impact
Dust cover, the noise that thumping is caused to dash forward can also cause dust cover to damage.In order to solve this problem, it is necessary to propose a kind of
Loud speaker bilayer dust cover structure.
【Utility model content】
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of loud speaker bilayer dust cover knot
Structure is aimed to solve the problem that in the prior art for mega bass loud speaker, under mega bass working condition, because above and below high intensity
Movement causes air compression to have little time to exclude from beneath, directly impacts dust cover, the noise that thumping is caused to dash forward can also be made
The technical issues of being damaged into dust cover.
To achieve the above object, it is dust-proof including upper strata the utility model proposes a kind of loud speaker bilayer dust cover structure
Cover and lower floor's dust cover, the upper strata dust cover are located at the top of lower floor's dust cover, and the upper strata dust cover is mounted on and raises
In the cone basin of sound device, lower floor's dust cover is mounted on the speech coil framework of loud speaker.
Preferably, the upper strata dust cover is in the outer male structure of spherical crown shape, and the edge of upper strata dust cover is turned-out
It is converted into and the matched coniform flanging of cone basin.
Preferably, the rounded structure of lower floor's dust cover, and the edge of lower floor's dust cover is turned over downwards and pacifies
Mounted in the upper end of speech coil framework, by several apertures are distributed on lower floor's dust cover,
Preferably, several apertures are distributed in the inside of speech coil framework upper port, the small aperture and sound
The ratio between internal diameter of ring framework is 1：.
Preferably, the ratio between the small aperture and internal diameter of speech coil framework are 1：52.
The beneficial effects of the utility model：Compared with prior art, a kind of loud speaker bilayer provided by the utility model is prevented
Dust hood structure, it is rational in infrastructure, on the basis of original dust cover, then a dust cover is added, can be played by lower floor's dust cover
The effect of buffering avoids the air under high speed impact from directly impacting upper strata dust cover, and if being uniformly provided on lower floor's dust cover
Dry aperture, the air compression energy caused by high intensity moves up and down are gone out from these apertures in time, and flat noise abatement while has
Effect extends the service life of upper strata dust cover, solves current mega bass loud speaker under mega bass working condition, because
Air compression is caused to have little time to exclude from beneath for high intensity up and down motion, directly impact dust cover, thumping has been caused to dash forward
Noise, the technical issues of also dust cover being caused to damage.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
