Description
Technical Field
The present invention relates to a speaker, and more particularly, to a supporting plate speaker structure without an elastic wave.
Background
The loudspeaker is a transducer for converting an electric signal into an acoustic signal, and the quality of the loudspeaker has great influence on the sound quality. The loudspeaker is the weakest component in the audio equipment, and is the most important component for the audio effect. The audio frequency electric energy makes the cone or diaphragm vibrate and generate resonance with the surrounding air to make sound through electromagnetic, piezoelectric or electrostatic effect.
At present, most of loudspeakers adopt a rubber edge and an elastic wave support piece to position the vibration part of the loudspeaker to move up and down, and the rubber edge and the elastic wave support piece occupy larger installation space, so that the space for installing a voice coil in the structure is reduced, and the large-caliber voice coil cannot be adopted, so that the loudspeaker is poor in efficiency and original sound reduction effect, and the sound effect of the whole sound system cannot reach the optimal value, and the requirements of consumption on the efficiency and the sound of the loudspeaker cannot be met.
Therefore, the technical personnel in the field are dedicated to develop a damper-free support piece loudspeaker structure which is simple in structure, reasonable in design, capable of reasonably improving the caliber of a voice coil and high in medium and low frequency sound reduction degree.
SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a damper-free support speaker structure with simple structure, reasonable design, reasonably improved voice coil caliber, and high middle and low frequency sound reproduction.
In order to achieve the purpose, the utility model provides a damper-free supporting piece loudspeaker structure, which comprises a loudspeaker body, wherein the loudspeaker body comprises a bracket which is of an external overall conical box structure and is provided with an opening at the upper end, and a loudspeaker magnetic circuit is arranged in the bracket; the loudspeaker magnetic circuit is characterized in that a circle of annular butt joint groove is formed in the edge position of the upper end face of the loudspeaker magnetic circuit, a vertically arranged voice coil designed in a cylindrical structure is arranged above the loudspeaker magnetic circuit inside the support, the lower end of the voice coil is correspondingly inserted into the butt joint groove, a spherical structure is arranged above the voice coil and a carbon fiber basin which protrudes upwards is arranged above the voice coil, the edge of the carbon fiber basin extends towards the upper part of the outer side in an inclined mode to form an extending part of a circle of annular structure, a circle of glue edge designed in an annular structure is arranged between the extending part and the opening end of the support, the inner side edge of the glue edge is connected with the outer side edge of the extending part, and the outer side edge of the glue edge is installed and fixed at the opening end of the support.
In this way, in the above speaker structure, the bracket serves as a support member to support the magnetic circuit and the rubber edge of the speaker, and the magnetic field generated by interaction between the magnetic circuit and the voice coil of the speaker makes the vibration part (the carbon fiber woven basin) of the speaker move up and down and vibrate with air to generate sound. The adoption of the carbon fiber woven basin can reduce the weight of the vibrating part. Compared with the loudspeaker structure of the original structure, the damper support piece is omitted, so that the corresponding installation space is saved in the support, the radial size for installing the voice coil is larger, the voice coil size capable of being installed is larger under the condition that the size of the support is not changed, the caliber of the voice coil can be more reasonably improved, and the medium-low frequency sound reduction degree is higher.
Preferably, the cross section of the rubber edge is of a semicircular structure which is arranged in an upward arch mode, and the inner side edge of the rubber edge extends towards the inner lower side to form a lap joint part and is attached to the upper surface of the edge of the extending part.
Therefore, in the process of up-and-down movement of the carbon fiber woven basin, the rubber edge can be better deformed and restored. The structural design is simpler and more reasonable.
As the optimization, glue limit outside edge level outside extension forms the annular crimping portion of round, corresponds at the uncovered position of support the crimping portion is equipped with the installation face that the annular of round and level set up, is equipped with the clamping ring above the crimping portion, and the clamping ring can the butt in crimping portion up end so that crimping portion lower surface pastes on the installation face.
Therefore, the crimping part and the mounting surface are designed, and the pressing ring is adopted for pressing, so that the crimping part can be mounted and fixed on the mounting surface better.
As optimization, a circle of annular abdicating groove is arranged at the edge position of the outer side of the mounting surface.
Like this, the groove of stepping down of design for the crimping portion outside can have the trend of buckling downwards, compresses tightly the back, makes the installation inseparabler between crimping portion and the installation face.
Preferably, a circle of crimping protrusions protruding upwards is arranged on the upper surface of the crimping portion and corresponds to the pressing ring.
Like this, through setting up the crimping arch, can be better with the clamping ring cooperation.
As optimization, the edge of the outer side of the carbon fiber basin bends downwards to form a circle of sleeving part and is sleeved at the upper end of the voice coil, and the lower end of the sleeving part slantly extends towards the upper part of the outer side to form the extending part.
Like this, the carbon fiber basin can retrain the voice coil loudspeaker voice coil for what the voice coil loudspeaker voice coil can be better just is located carbon fiber basin below.
Preferably, a circle of nano liquid suspension glue with an annular structure is arranged between the outer circumferential surface of the voice coil and the side wall of the butt joint groove.
Like this, the liquid suspension of nanometer is glued the location and can be played the installation limiting displacement to the voice coil loudspeaker voice coil, still plays sealed effect to a certain extent.
The utility model has the beneficial effects that: according to the utility model, the damper support piece is omitted, and the corresponding mounting space is saved in the support, so that the radial size for mounting the voice coil is larger, and the size of the voice coil which can be mounted and arranged is larger under the condition that the size of the support is not changed, thereby the caliber of the voice coil can be more reasonably improved, and the degree of reduction of middle and low frequency sound is higher. The problem of traditional have the limit in the aspect of play ripples foil loudspeaker can only use the small-bore voice coil loudspeaker voice coil is solved. The small-caliber loudspeaker without the damper support piece can adopt a large-caliber voice coil (more than 50 mm), so that the loudspeaker has high efficacy and high medium and low frequency sound reduction degree.
