Abstract
Provided is an electrodynamic type loudspeaker without positioning support chips. The electrodynamic type loudspeaker without positioning support chips comprises a basin rack, a cone basin, voice coils, a dust shield, and a magnetizer. The electrodynamic type loudspeaker without positioning support chips is characterized in that: the cross section of the magnetizer is E-shaped with the opening of the E being upwards; annular magnets are applied to the outer sides of the gaps of the E-shaped magnetizer; the integral bodies of the voice coils are put into the gaps of the E-shaped magnetizer; the bottom surface of the basin rack is arranged above the open end surface of the E-shaped magnetizer. Compared with traditional magnetic circuit systems, a magnetic circuit system of the electrodynamic type loudspeaker without positioning support chips of the utility model is characterized by being smaller in size, lower in cost, and longer in magnetic air gaps. Since the magnetic air gap is long, the voice coils all work in uniform magnetic fields in a large dynamic scope, and cutting magnetic lines of force are equal in the large dynamic scope. Harmonic wave distortion due to a nonuniform magnetic circuit system is solved. The electrodynamic type loudspeaker without positioning support chips is characterized by being good in low frequency effect and light in weight.
Description
Technical field
The utility model relates to loadspeaker structure, specifically refers to a kind of without the locating branch slice dynamic speaker.
Background technology
The dynamic speaker of prior art comprises that basin frame, cone basin, voice coil loudspeaker voice coil, dust cover, cross section are the lower magnetic conductive board of inverted T-shape and the upper conduction magnetic board of ring-type, and the magnet of ring-type is placed between upper conduction magnetic board and lower magnetic conductive board, and the voice coil loudspeaker voice coil tandem arrangement is on lower magnetic conductive board.Because having the part voice coil loudspeaker voice coil all the time, structural reason is operated in inhomogeneous volume magnetic field, magnetic air gap both sides, cause harmonic distortion, especially obvious in low frequency performance, the dynamic speaker of this structure simultaneously, between its basin frame and cone basin, locating branch slice is arranged, the quality of loud speaker is larger.
Summary of the invention
The purpose of this utility model is for the problems referred to above, propose a kind of low-frequency effect good without the locating branch slice dynamic speaker.
The purpose of this utility model is achieved in that of the present utility model a kind of without the locating branch slice dynamic speaker, it comprises basin frame, cone basin, voice coil loudspeaker voice coil, dust cover and magnetic conductor, it is characterized in that the magnetic conductor cross section is opening up E font, the magnet of ring-type is fitted in the outside in E font magnetic conductor space, voice coil loudspeaker voice coil integral body is placed in the space of E font magnetic conductor, and the bottom surface of basin frame is placed on the open end of E font magnetic conductor.
Of the present utility model without the locating branch slice dynamic speaker, because the magnetic conductor cross section is opening up E font, the magnet of ring-type is fitted in the outside in E font magnetic conductor space, voice coil loudspeaker voice coil integral body is placed in the space of E font magnetic conductor, the bottom surface of basin frame is placed on the open end of E font magnetic conductor, without locating branch slice, the magnetic circuit system that magnetic circuit system is relatively traditional, has volume less, cost is lower, the characteristics that magnetic air gap length is long, magnetic air gap length length can make voice coil loudspeaker voice coil all in magnetic field, work uniformly in great dynamic range.The cutting magnetic line of voice coil loudspeaker voice coil in dynamic range all equates like this, overcome the harmonic distortion caused because magnetic circuit system is inhomogeneous.Have good, the lightweight characteristics of low-frequency effect.
The accompanying drawing explanation
Fig. 1 is the structural representation without the locating branch slice dynamic speaker of the present utility model.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing:
As shown in Figure 1, of the present utility model a kind of without the locating branch slice dynamic speaker, it comprises basin frame 1, cone basin 2, voice coil loudspeaker voice coil 4, dust cover 3 and magnetic conductor 6, it is characterized in that magnetic conductor 6 cross sections are opening up E font, the magnet 5 of ring-type is fitted in the outside in E font magnetic conductor 6 spaces, voice coil loudspeaker voice coil 4 integral body are placed in the space of E font magnetic conductor 6, and the bottom surface of basin frame 1 is placed on the open end of E font magnetic conductor 6.
