Description
Technical field
The utility model relates to a kind of loud speaker, particularly relates to a kind of loud speaker on Baffle Box of Bluetooth.
Background technology
Baffle Box of Bluetooth connects with bluetooth and replaces the connection of traditional wire rod, by being connected with bluetooth playback equipments such as mobile phone, panel computer and notebooks, allow user can exempt impeding of irritating electric wire, listoning music in every way convenient, comfortablely, particularly can meet the Music Appreciation requirement in the outdoor activities of people's door, thus be subject to the extensive concern of user.Baffle Box of Bluetooth wants that cube is little, sound articulation is higher, and will shake regret, high pitch of bass is bright and soft, and this just proposes higher requirement to loud speaker.
People know, the diaphragm of loudspeaker is one of principal element affecting loud speaker tonequality, and determine that the leading factor of diaphragm mass roughly has following several respects: the rigidity of vibrating diaphragm, the size of the internal damping size of vibrating diaphragm and diaphragm mass (weight), generally, high rigidity, high internal damping characteristics is one of target of pursuing of high-quality vibrating diaphragm, this two indices is interrelated but is condition each other and contradiction, be difficult to find a kind of rigidity strong again and the out of this world perfect diaphragm materials of internal damping characteristics, and after the rigidity of vibrating diaphragm and internal damping size are determined, the quality of same size vibrating diaphragm has direct association with the thickness of vibrating diaphragm.On conventional Baffle Box of Bluetooth loud speaker, vibrating diaphragm used is metal forming diaphragm, metal forming diaphragm is connected with loudspeaker support by the compound boundary of its outer ring, metal forming diaphragm has higher rigidity, but it is internally-damped little, reverberation is had to exist after programme signal terminates, high frequency (usual 10 ~ 15KHz) has high-frequency resonance peak, causes high frequency ear-piercing, can affect overall sense of hearing.
Utility model content
For the above-mentioned deficiency existing for prior art, technical problem to be solved in the utility model is to provide a kind of bluetooth loud speaker, and it can avoid the issuable reverberation of metal forming diaphragm, improves acoustical quality.
In order to solve the problems of the technologies described above, a kind of Baffle Box of Bluetooth loud speaker of the present utility model, comprise support, vibrating diaphragm, voice coil loudspeaker voice coil and connect the ring of vibrating diaphragm and support, described vibrating diaphragm comprises metal forming diaphragm, has rubber layer at metal forming diaphragm Surface coating; The thickness A of described metal forming diaphragm is 0.06-0.085mm, and the thickness B of described rubber layer is 0.1-0.3mm.
In said structure, because described vibrating diaphragm comprises metal forming diaphragm, rubber layer is had at metal forming diaphragm Surface coating, then the vibrating diaphragm of metal forming diaphragm has higher rigidity, can guarantee that the diaphagras of vibrating diaphragm can effectively be suppressed, it is to producing bright high pitch effect, reduce the distortion of vibrating diaphragm, widen frequency bandwidth and all can produce important effect, and be connected as a single entity at the surface coated rubber layer of metal forming diaphragm and metal forming diaphragm, because metal forming diaphragm internal loss is very little, only have 1/10 of paper vibrating diaphragm, and elastomeric material is internally-damped larger, rubber layer is coated on the reverberation that metal forming diaphragm can absorb in metal forming diaphragm, increase the oscillating mass of vibrating diaphragm, reduce resonance frequency, be conducive to the regeneration of low-frequency minimum, again because the thickness A of described metal forming diaphragm is 0.06-0.085mm, the thickness B of described rubber layer is 0.1-0.3mm, then when the vibrating diaphragm that the above-mentioned metal forming diaphragm being coated with rubber layer is formed, after adopting the thick metal forming diaphragm of 0.06-0.085mm and the thick rubber layer of 0.1-0.3mm to combine, the rigidity of vibrating diaphragm, internal damping and oscillating mass can mate mutually, meet the resonant frequency requirement of Baffle Box of Bluetooth loud speaker, make the Baffle Box of Bluetooth bass dynamics of this loud speaker of employing strong, intermediate frequency has higher definition, high frequency is bright and soft, overall sense of hearing is better, thus acoustical quality is greatly improved.
A kind of preferred implementation of the present utility model, described metal forming diaphragm comprises indent domed vibrating diaphragm main body and is positioned at the bias limit of spherical outer ring, and this bias edge break is to side, spherical crown top.Adopt this execution mode, sound can directly diffuse in air by the domed vibrating diaphragm main body of indent, and greatly improve energy conversion efficiency, improve the sensitivity of loud speaker, and vibrating diaphragm has larger power bearing ability, tone color is comparatively pure.
Another kind of preferred implementation of the present utility model, is also provided with the cylindricality flanging be connected with voice coil loudspeaker voice coil in the outer ring on described bias limit.Adopt this execution mode, cylindricality tuck portion is cylindric, and directly can be socketed with the voice coil loudspeaker voice coil of cylindrical shape, the connection of vibrating diaphragm and voice coil loudspeaker voice coil is reliable.
Another preferred implementation of the present utility model, described metal forming diaphragm is aluminium foil diaphragm.Adopt this execution mode, aluminium foil diaphragm is advantage of lower cost compared with the metal forming diaphragm of other type, manufactures also more for convenience.
The further preferred implementation of the utility model, the thickness A of described metal forming diaphragm is 0.075mm, and the thickness B of described rubber layer is 0.2mm.Adopt this execution mode, the quality of formed vibrating diaphragm and the rigidity of vibrating diaphragm and internal damping size matching effect can be made best, ensure the acoustical quality of loud speaker better.
Another further preferred implementation of the utility model, described rubber layer is coated on the concave surface of metal forming diaphragm indent spherical crown and the outer surface on bias limit, and be connected with the corrugated gasket inner ring of ring, the clamping ring that ring is connected with support installing is connected in the outer ring of corrugated gasket.Adopt this execution mode, the coated and ring of metal forming diaphragm, rubber layer is connected as a single entity effectively, makes the compliance of vibrating diaphragm better, also ensure that the connection between vibrating diaphragm and support better.
