Abstract
The utility model discloses a loudspeaker device which comprises a vibration system. The vibration system comprises a voice coil, a diaphragm and a magnetic circuit system. The voice coil comprises a main body and a voice coil lead wire. The magnetic circuit system includes a housing, a washer and a magnet. The housing is provided with a pad. The voice coil is electrically connected with an external circuit through the pad. The housing is also provided with a sinking step which is arranged on the pad adjacent to the lead wire of the voice coil. The lead wire of the voice coil passes through an upper side of the step to be welded with the pad. The loudspeaker device has the advantages of excellent sound performance and high reliability.
Description
Technical field
The utility model relates to speaker unit, and it is good especially to relate to a kind of sound performance, the speaker unit that reliability is high.
Background technology
Along with the development of electroacoustic techniques, the range of application of speaker unit constantly enlarges, and people are also more and more higher to the requirement of speaker unit, and when people paid close attention to the loudspeaker sound performance, the reliability of speaker unit also was people's outline.
The speaker unit of conventional art, its voice coil loudspeaker voice coil and the welding of shell pad, voice coil leads is in the voice coil loudspeaker voice coil vibration processes, easily with plane contact except pad, the loudspeaker sound performance is exerted an influence, simultaneously, easily cause the voice coil leads broken string, reduced the reliability of speaker unit.
Therefore, be necessary to propose a kind of improvement, to overcome defects.
The utility model content
It is good that technical problem to be solved in the utility model provides a kind of sound performance, the speaker unit that reliability is high.
To achieve these goals, the utility model is by the following technical solutions:
A kind of speaker unit, the involving vibrations system, described vibrational system comprises voice coil loudspeaker voice coil and vibrating diaphragm, voice coil loudspeaker voice coil comprises main body and voice coil leads; And magnetic circuit system, described magnetic circuit system comprises shell, washer and magnet, and described shell is provided with pad, and described voice coil loudspeaker voice coil is electrically connected with external circuit by described pad; And: described shell also is provided with sagging step, and described sagging step is arranged at described pad in the adjacent position of the lead-in wire direction of described voice coil loudspeaker voice coil; Described voice coil leads is passed described step upside and the welding of described pad.
As a kind of preferred technical scheme, described sagging step place is provided with colloid, and described colloid wraps up described voice coil leads correspondence position.
The utility model speaker unit, voice coil leads and housing contacts can be effectively avoided in the design of the step that sink, and have improved sensitivity and the sound performance of speaker unit; Sagging step place's point glue, colloid parcel voice coil leads can be decomposed lead-in wire suffered stress in vibration the time, make product have more excellent reliability.Therefore, the utility model speaker unit has the reliability height, the advantage that sound performance is good.
Description of drawings
Fig. 1 is the utility model speaker unit cutaway view.
Fig. 2 is the utility model part-structure stereogram.
Embodiment
Below in conjunction with accompanying drawing, describe the utility model in detail.
As shown in Figure 1, the utility model speaker unit comprises the vibrational system that is comprised of voice coil loudspeaker voice coil 2 and vibrating diaphragm 7; And by shell 1, the magnetic circuit system that magnet 5 and washer 6 form.In order to make the utility model structure more directly perceived, and more clearly describe the utility model, vibrating diaphragm 7 among Fig. 2, and magnet 5 and washer 6 are not shown, and its 26S Proteasome Structure and Function is identical with the speaker unit of known technology.
As shown in Figure 2, be provided with pad 3 on the shell 1 of the utility model speaker unit, the voice coil leads 21 of voice coil loudspeaker voice coil 2 and pad 3 welding.Pad 3 is provided with the step 4 that sink in incoming direction one side of voice coil leads 21, and voice coil leads 21 is passed step 4 upsides that sink, with pad 3 welding.The step 4 that sink can avoid voice coil leads 21 to contact the sensitivity of Effective Raise speaker unit and sound performance with shell 1 other parts except pad 3.
As a kind of preferred, by point gum machine point glue, glue voice coil leads 21 correspondence positions of naming a person for a particular job wrap up on the step 4 that sink.Such design can be decomposed voice coil leads 21 suffered stress when voice coil loudspeaker voice coil 2 vibrates, and avoids voice coil loudspeaker voice coil 2 broken strings, the reliability of Effective Raise speaker unit.
The utility model speaker unit, the design of the step 4 that sink can improve sensitivity and the sound performance of speaker unit; Sink and to put glue on the step 4, reliability that can the Effective Raise speaker unit.
Be the utility model case study on implementation only below, be not limited to the utility model, as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection range of putting down in writing in claims.
Claims (2)
