Abstract
Disclosed is an electroacoustic transducer, comprising a voice coil and a magnetic circuit system, wherein the magnetic circuit system forms a magnetic gap for receiving the voice coil; and the voice coil is a structure having more than one layers, with the layer number thereof being odd. The voice coil of this structure is capable of effectively controlling the height of the voice coil and ensures the acoustic performance of the electroacoustic transducer.
Description
Technical field
The utility model relates to the electroacoustic field, is specifically related to a kind of electroacoustic transducer that can effectively control the voice coil loudspeaker voice coil height.
Background technology
Electroacoustic transducer comprises voice coil loudspeaker voice coil and magnetic circuit system, and magnetic circuit system forms the magnetic gap of accommodating voice coil loudspeaker voice coil.Voice coil loudspeaker voice coil all adopts the structure of individual layer or even level in the prior art, and for the voice coil loudspeaker voice coil of even level, the Height Adjustment of voice coil loudspeaker voice coil has certain limitation, causes voice coil loudspeaker voice coil too high or excessively short; Voice coil loudspeaker voice coil is too high, and to cause easily the structure of voice coil loudspeaker voice coil lower end and voice coil loudspeaker voice coil downside to bump etc. bad; Voice coil loudspeaker voice coil is crossed the short voice coil loudspeaker voice coil that then can cause in the offset of magnetic gap meta, and the magnetic field utilance is low, also can cause simultaneously magnetic gap wide, reduces the magnetic field performance.Therefore, be necessary the electroacoustic transducer of this structure is improved, to avoid defects.
Therefore, be necessary the electroacoustic transducer of this structure is improved, to avoid defects.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of electroacoustic transducer, can control the height of voice coil loudspeaker voice coil, guarantees the acoustical behavior of product.
To achieve these goals, the utility model provides a kind of electroacoustic transducer, comprises voice coil loudspeaker voice coil and magnetic circuit system, and described magnetic circuit system forms the magnetic gap of accommodating described voice coil loudspeaker voice coil, and wherein, described voice coil loudspeaker voice coil is the above structure of one deck, and the number of plies of described voice coil loudspeaker voice coil is odd number.
In addition, preferably scheme is, described voice coil loudspeaker voice coil comprises two lead-in wires, and described lead-in wire is drawn from the top and bottom of described voice coil loudspeaker voice coil respectively.
In addition, preferred scheme is that the number of plies of described voice coil loudspeaker voice coil is three layers.
In addition, preferred scheme is that the number of plies of described voice coil loudspeaker voice coil is five layers.
After adopting technique scheme, compare with traditional structure, the voice coil loudspeaker voice coil of the utility model electroacoustic transducer is the odd-level structure of multilayer, and the voice coil loudspeaker voice coil of this structure can effectively be controlled the height of voice coil loudspeaker voice coil, has guaranteed the acoustical behavior of electroacoustic transducer.
Description of drawings
By below in conjunction with accompanying drawing present embodiment being described, above-mentioned feature of the present utility model and technological merit will become apparent and understand easily.
Fig. 1 is the cross-sectional view of the utility model embodiment one electroacoustic transducer.
Fig. 2 is the perspective view of the utility model embodiment one voice coil loudspeaker voice coil.
Fig. 3 is the cutaway view of the utility model embodiment one voice coil loudspeaker voice coil.
Fig. 4 is the cutaway view of the utility model embodiment two electroacoustic transducer voice coil loudspeaker voice coils.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done further detailed description.
Embodiment one:
As shown in Figure 1 to Figure 3, electroacoustic transducer involving vibrations system, magnetic circuit system, and accommodate the fixedly auxiliary system of vibrational system and magnetic circuit system.Wherein vibrational system comprises vibrating diaphragm 21 and the voice coil loudspeaker voice coil 22 that is incorporated into vibrating diaphragm 21 downsides, and magnetic circuit system comprises washer 31, magnet 32 and the basin frame 33 of successively combination, and magnetic circuit system forms the magnetic gap of accommodating voice coil loudspeaker voice coil 22.Auxiliary system comprises the fixedly shell 12 of magnetic circuit system, is combined with vibrating diaphragm 21 on the upper side of shell 12, and protecgulum 11 lids are connected to the upper edge of vibrating diaphragm 21, protecgulum 11 and the shell 12 common peripheral frame that form electroacoustic transducer.
Voice coil loudspeaker voice coil 22 is sandwich construction, odd-level structure preferably, and in the present embodiment, voice coil loudspeaker voice coil 22 is three layers, as shown in Figure 3, voice coil loudspeaker voice coil 22 comprises two lead-in wires: lead-in wire 221a and lead-in wire 221b.In voice coil loudspeaker voice coil 22 winding process, coiling innermost layer voice coil loudspeaker voice coil at first, then successively outwards coiling, lead-in wire 221a and lead-in wire 221b lay respectively at the coiling starting point of voice coil loudspeaker voice coil 22 and the position of terminal point.
The voice coil loudspeaker voice coil 22 of this odd-level structure, can effectively control the height on voice coil loudspeaker voice coil 22 vertical directions (voice coil loudspeaker voice coil direction of vibration), thereby can make voice coil loudspeaker voice coil 22 effectively utilize the magnetic line of force, and the width of required magnetic gap is less, thereby has guaranteed the acoustical behavior that electroacoustic transducer is good.
Embodiment two:
Fig. 4 is the cutaway view of the utility model embodiment two electroacoustic transducer voice coil loudspeaker voice coils, as shown in Figure 4, the main distinction of present embodiment and embodiment one is, present embodiment voice coil loudspeaker voice coil 22 ' is five-layer structure, the voice coil loudspeaker voice coil 22 ' of this five-layer structure can better be controlled the height of voice coil loudspeaker voice coil 22 ' in the vertical direction equally, thereby has guaranteed the acoustical behavior of electroacoustic transducer.
Under above-mentioned instruction of the present utility model; those skilled in the art can carry out on the basis of above-described embodiment other improvement and distortion; such as can be on voice coil loudspeaker voice coil sheathed speech coil framework etc.; and these improvement and distortion; all drop in the protection range of the present utility model; it will be understood by those skilled in the art that the just better the purpose of this utility model of explaining of above-mentioned specific descriptions, protection range of the present utility model is limited by claim and equivalent thereof.
