Embodiment
Core of the present utility model there is provided a kind of loudspeaker, improves the sensitivity of the loudspeaker adopting center drilling washer.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to shown in Fig. 2-Fig. 4, the utility model embodiment provides a kind of loudspeaker, mainly comprise washer 1, magnet 3, vibrating diaphragm 2 and voice coil loudspeaker voice coil 4, voice coil loudspeaker voice coil 4 is fixedly connected with vibrating diaphragm 2, usually, in order to strengthen the performance of loudspeaker at high frequency treatment, vibrating diaphragm 2 is combined with strengthening course 201, in this application, strengthening course 201 is recessed structure.The end face laminating of washer 1 and magnet 3 is fixing, is generally bonding fixing.Voice coil loudspeaker voice coil 4 is generally by electric connection structure (such as shell fragment, pad etc.) and the external circuit mutual conduction of loudspeaker, when the current signal of external circuit is passed to voice coil loudspeaker voice coil 4, voice coil loudspeaker voice coil 4 is cutting magnetic line under the active force of electromagnetic field, the variation be subjected to displacement, and then drive and be attached thereto the vibrating diaphragm 2 connect and vibrate, outwardly radiative acoustic wave, completes electric energy to sound transformation of energy.
In the structure that above-mentioned strengthening course 201 is recessed, in order to ensure downward oscillation space, the one side of the close magnet 3 of washer 1 is provided with hollow out 101, and on magnet 3, the position of corresponding hollow out 101 has been wholely set projection magnet 301, and projection magnet 301 is filled and is flush-mounted in the space of hollow out 101.
Because the hollow out 101 of existing washer 1 is not fully utilized, therefore, magnet 3 of the present utility model is provided with projection magnet 301, projection magnet 301 is flush-mounted in hollow out 101, take full advantage of the idle space of washer 1, do not affecting oscillation space and under not reaching magnetically saturated situation, the volume of magnet 3 is increased by setting up projection magnet 301, and then increase magnetic field, when voice coil loudspeaker voice coil 4 length is constant, improves the utilance in magnetic field, thus improve loudspeaker sensitivity, through test, sensitivity improves about 0.25dB.
As shown in Figure 4, in the present embodiment, projection magnet 301 can be to the bulge-structure that the direction of washer 1 extends on magnet 3, and projection magnet 301 is one-body molded with magnet 3; But consider the making technology of current magnet, this direct integrated structure implements difficulty may be larger, therefore also can by projection magnet 301 and magnet 3 shaping separately, be then adhesively fixed by gluing and be integrated.
It is readily understood that in order to reach the purpose of this utility model, projection magnet 301 and hollow out 101 all should be positioned at magnet 3 with on the relative end face of washer 1, and, preferably, the medium position of magnet 3 and washer 1 should be positioned at, corresponding with recessed strengthening course 201.
In the present embodiment, hollow out 101 is rectangle, and the length of hollow out 101 is 8.5 ~ 9mm, the width of hollow out 101 is 2 ~ 3mm, the height of hollow out 101 is 0.2 ~ 0.3mm, and this gives the size of a concrete hollow out 101, its length is respectively 8.92mm, 2.54mm, 0.25mm.Certainly, arrange according to the actual size of loudspeaker and sensitivity requirement, be not limited to the scope cited by the present embodiment.
In order to make full use of the idle space of hollow out 101, as shown in Fig. 2-Fig. 3, in the present embodiment, the size of projection magnet 301 and the measure-alike of hollow out 101, thus projection magnet 301 is filled with completely in hollow out 101, improve loudspeaker sensitivity to greatest extent.Certainly, also projection magnet 301 can be partially filled in hollow out 101, as long as magnet volume can be increased on original magnet 3 basis, all loudspeaker sensitivity can be improved to a certain extent.
In this specification, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
