Abstract
Disclosed in the utility model is a super-high pitch loudspeaker with improved high-frequency bandwidth and sensitivity. The provided loudspeaker comprises a vibrating system, a magnetic circuit system and an auxiliary system. Specifically, the vibrating system consists of a voice diaphragm (8), a voice coil (12), an iron net (7) and a voice diaphragm support (3); the magnetic circuit system includes a U iron (4), a main magnet (5), a wahser (6), a reversed-polarity secondary magnet (10) and a copper sleeve (11); and the auxiliary system includes a housing (1), an upper cover (2), and a sound-absorbing cotton (9). According to the super-high pitch loudspeaker provided by the utility model, the high-frequency output of the loudspeaker is increased and the frequency response is widened; and harmonic distortion can be reduced and sensitivity of the whole frequency range of 1 to 2dB can be improved.
Description
Technical field
The utility model relates to superelevation loudspeaker techniques field, relates in particular to a kind of super high pitch loudspeaker that can effectively promote frequency range and sensitivity.
Background technology
Super high pitch loudspeaker is exactly the ultrahigh frequency loudspeaker unit in the loud speaker, the utilance of magnetic magnetic circuit (U iron+main magnetic+washer) magnetic flux is lower and harmonic distortion is also larger comparatively speaking in traditional super high pitch loudspeaker, can't satisfy the requirement of super high pitch loudspeaker, still more on higher frequency, because the inductance increase of voice coil loudspeaker voice coil increases total impedance, the electric current of then inputting voice coil loudspeaker voice coil reduces, and causes high frequency output minimizing, the frequency range of high pitch loudspeaker to narrow down.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model provides a kind of super high pitch loudspeaker that can effectively promote frequency range and sensitivity.
The utility model is to realize by following technical scheme:
The super high pitch loudspeaker that effect promotes frequency range and sensitivity comprises: vibroseis, magnetic circuit system and auxiliary system; Described
Vibroseis comprises sound film (8) and voice coil loudspeaker voice coil (12);
Magnetic circuit system comprises U iron (4), main magnetic (5), washer (6), the secondary magnetic (10) of reversed polarity and copper sheathing (11);
Auxiliary system comprises housing (1), loam cake (2), iron net (7), sound membrane support (3) and acoustical cotton (9).
Compared with prior art, one or more embodiment of the present utility model can have following advantage:
The super high pitch loudspeaker that the utility model provides can make high frequency output increase, the frequency response of loud speaker widen, and can also reduce harmonic distortion, promotes the sensitivity of whole frequency range 1～2dB.
Other features and advantages of the utility model will be set forth in the following description, and, partly from specification, become apparent, perhaps understand by implementing the utility model.The purpose of this utility model and other advantages can realize and obtain by specifically noted structure in specification, claims and accompanying drawing.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and consists of the part of specification, jointly is used for explaining the present invention with embodiment of the present utility model, does not consist of restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the super high pitch loudspeaker structure chart that promotes high frequency frequency range and sensitivity.
Wherein 1 is that 1 housing, 2 is that loam cake, 3 is that sound membrane support, 4 is that U iron, 5 is that main magnetic, 6 is that washer, 7 is that iron net, 8 is that sound film, 9 is that acoustical cotton, 10 is that reversed polarity pair magnetic, 11 is that copper sheathing, 12 is voice coil loudspeaker voice coil.
Embodiment
Understand easily, according to the technical solution of the utility model, do not changing under the connotation of the present utility model, one of ordinary skill in the art can propose a plurality of frame mode of the present utility model and manufacture method.Therefore following embodiment and accompanying drawing only are specifying of the technical solution of the utility model, and should not be considered as of the present utility model all or be considered as restriction or the restriction of technical solutions of the utility model.
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.
Fig. 1 is the structural representation according to the super high pitch loudspeaker of the lifting high frequency frequency range of the utility model embodiment and sensitivity, below with reference to Fig. 1, describes the various piece of the utility model embodiment and the function of various piece in detail.
As shown in Figure 1, the structure for the super high pitch loudspeaker that promotes high frequency frequency range and sensitivity comprises: vibroseis, magnetic circuit system and auxiliary system; Described
Vibroseis comprises sound film 8 and voice coil loudspeaker voice coil 12;
Magnetic circuit system comprises U iron 4, main magnetic 5, washer 6, the secondary magnetic 10 of reversed polarity and copper sheathing 11;
Auxiliary system comprises housing 1, loam cake 2, iron net 7, sound membrane support 3 and acoustical cotton 9.
Above-mentioned voice coil loudspeaker voice coil 12 is connected in sound film 8, and supports whole magnetic circuit system by sound membrane support 3.
Above-mentioned main magnetic 5 devices are in U iron 4;
Washer 6 is arranged on the main magnetic 5, and is arranged with copper sheathing 11 at washer 6, and the secondary magnetic 10 of reversed polarity is housed on the copper sheathing 11.
Above-mentioned loam cake 2 is arranged in the housing 1, and is equipped with iron net 7 on housing;
The secondary magnetic of above-mentioned reversed polarity is for increasing the high frequency output of loud speaker, widen frequency response, to promote magnetic flux;
Copper sheathing is used for offsetting the induction reactance that produces because of frequency rising voice coil loudspeaker voice coil.
The secondary magnetic of above-mentioned reversed polarity promotes 1～2dB of whole frequency range.
Above-mentioned copper sheathing can be offset the induction reactance that produces because of frequency rising voice coil loudspeaker voice coil, thereby impedance is reduced, and then the input current of voice coil loudspeaker voice coil increases, and therefore, high frequency output increase, the frequency response of loud speaker is widened, and can also reduce harmonic distortion; The secondary magnetic of the reversed polarity that increases is more direct than the method that other adds secondary magnetic, more effectively promote magnetic flux, thereby promotes the sensitivity of whole frequency range 1～2dB.
Although the disclosed execution mode of the utility model as above, the execution mode that described content just adopts for the ease of understanding the utility model is not to limit the utility model.Technical staff under any the utility model in the technical field; under the prerequisite that does not break away from the disclosed spirit and scope of the utility model; can do any modification and variation in the details that reaches of implementing in form; but scope of patent protection of the present utility model still must be as the criterion with the scope that appending claims was defined.
