Description
Technical field
It the utility model is related to loudspeaker field, and in particular to a kind of Dome loudspeaker.
Background technology
Composite construction top dome in existing loudspeaker is often the composite membranes such as aluminium alloy, titanium alloy, magnesium alloy, and it prepares work
Skill is complicated, and cost is high.In addition, existing composite construction top dome is tabular, by coating glue below top dome to bond voice coil loudspeaker voice coil,
Its drawback is：1st, the coating track of glue need to be consistent with the profile of voice coil loudspeaker voice coil, and the track management and control to glue requires higher, easily goes out
Existing subregion glue excessively overflows, and subregion lacks glue；2nd, when loudspeaker applications are in the portable electricity such as mobile phone, flat board
During sub- product, there is harsh limitation to its thickness, when flat top dome is with voice coil loudspeaker voice coil adhesion, between top dome and protecgulum away from
From limited, and glue bonding is used, further cause the reduction of the distance between top dome and protecgulum, in speakers low frequencies large amplitude
In the case of, vibration interference souffle problem easily occurs, thus, the management and control of the coating height to glue requires higher.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of Dome loudspeaker.
To achieve the above object, the utility model uses following technical scheme：
A kind of Dome loudspeaker, including pedestal, magnetic circuit component, voice coil loudspeaker voice coil, ring, top dome and protecgulum, the ring are installed on
Between protecgulum and pedestal, the top dome is arranged on the central area of ring, what the top dome was provided with its edge of ring and was recessed upwards
Ring-shaped groove, the shape of the ring-shaped groove and the shape of the voice coil loudspeaker voice coil are coincide, and the voice coil loudspeaker voice coil is gluing in the ring-shaped groove.
Further, the top dome is made up of macromolecule material, and depression forms hemispherical groove upwards at the top dome center.
Further, if being provided with the concave up sunken strip ditch in arterial highway between the hemispherical groove and the ring-shaped groove
Groove.
Further, the high polymer material is PEN.
Further, the magnetic circuit component includes magnetic bowl, the magnet in magnetic bowl and the China positioned at magnet upper surface
Department, the upper surface of the washer are thinned along its edge to form a circular step.
After adopting the above technical scheme, the utility model compared with background technology, has the following advantages that：
1st, top dome edge is provided with the ring-shaped groove consistent with voice coil loudspeaker voice coil profile, and the ring-shaped groove conduct is led glue groove and used, has
Effect prevent glue from overflowing, so as to voice coil loudspeaker voice coil durable bond, and greatly reduce glue coating task difficulty；And the annular ditch
Groove is in upward concave design so that the bonding position of itself and voice coil loudspeaker voice coil is higher by the level of top dome, add top dome and protecgulum it
Between distance, avoid vibration interference souffle problem, and provide space for the low frequency lifting of loudspeaker；
2nd, in magnetic circuit component, the upper surface of washer is thinned to form a circular step along its edge, so as to effectively improve
The density of the magnetic line of force, leakage field is reduced, plus the top dome after optimization with larger vibration space, the significant increase electroacoustic of loudspeaker
Performance；
3rd, top dome is made using high polymer material, is machined with strip-shaped grooves and is carried out rigid reinforcement, center is then machined with half
Ball recess, and the strip-shaped grooves, ring-shaped groove and hemispherical groove and top dome are integrally formed, technique is simple, and cost is cheap,
But also with preferable rigidity while light quality, the advantages of traditional hard sphere top is with soft top dome is combined, makes wherein high frequency response
It is excellent, transient response is good, distortion is small, tonequality is preferable.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
Embodiment
As shown in Figures 1 and 2, a kind of Dome loudspeaker, including pedestal 1, magnetic bowl 2, magnet 3, washer 4, voice coil loudspeaker voice coil 5, ring
6th, top dome 7 and protecgulum 8.Between protecgulum 8 and pedestal 1, top dome 7 is bonded at the central area 61 of ring 6 clamping of ring 6.Such as
Shown in Fig. 2, Fig. 3 and Fig. 4, top dome 7 is provided with its edge of ring and the ring-shaped groove 71 being recessed upwards, the shape and sound of ring-shaped groove 71
The shape of circle 5 is coincide, and glue is coated in ring-shaped groove 71, the upper surface of voice coil loudspeaker voice coil 5 is gluing in ring-shaped groove 71.
Top dome 7 is made up of macromolecule material, in the present embodiment, is made using PEN.The center of top dome 7 is recessed upwards
Hemispherical groove 72 is formed, if being provided with the concave up sunken strip-shaped grooves 73 in arterial highway between hemispherical groove 72 and ring-shaped groove 71.
Magnetic bowl 2, the magnet 3 in magnetic bowl 2 and the washer 4 positioned at the upper surface of magnet 3 form magnetic circuit component.Such as Fig. 5
Shown, the upper surface of washer 4 is thinned to form a circular step 41 along its edge, because path of the magnetic line of force along magnetic resistance minimum leads to
Cross, so the ironed place of washer 4 is nearest path, many magnetic lines of force are assembled, conducted by washer 4 here, so as to effectively
