Description
Technical field
The present invention relates to a kind of loudspeaker, particularly relate to a kind of spread spectrum loudspeaker.
Background technology
It is known that the playback frequency band that single conventional horn can complete is narrower, in order to realize the sound reproduction of human ear audible audiorange, tradition playback system often takes many loudspeaker and frequency splitting technology to realize, but its sound sent easily produces and obscures and distortion.Therefore, improve existing loudspeaker, make it to expand playback frequency band range in the case of using single loudspeaker, reduce the distortion factor, avoid again using frequency divider, there is practical function.
Summary of the invention
Embodiment of the present invention technical problem to be solved is, it is provided that a kind of spread spectrum loudspeaker.Cover can be hung in the T-shaped iron core column of the most common bass horn set high pitch metal vibration diaphragm and realize wide band audio playback.
In order to solve above-mentioned technical problem, embodiments provide a kind of spread spectrum loudspeaker, including frame, bass vibrating diaphragm, voice coil loudspeaker voice coil, high pitch metal vibration diaphragm, play ripple support, T-shaped magnetic conduction ferrum, ring magneto conducting piece, described bass vibrating diaphragm one end is connected with frame, the other end is connected to form bass unit with described voice coil loudspeaker voice coil and bullet ripple support, described voice coil loudspeaker voice coil is arranged in the gapped magnetic field of described T-shaped magnetic conduction ferrum and described ring magneto conducting piece, described high pitch metal vibration diaphragm is suspended in the gapped magnetic field between described voice coil loudspeaker voice coil and described T-shaped conducting magnet core post formation voice unit by being arranged at the support member of described T-shaped conducting magnet core post.
Further, described high pitch metal vibration diaphragm cross section is n shape, and the top cover inwall of described n shape is fixing with described support member to be connected, and ring wall hangs and is arranged in the gapped magnetic field between described voice coil loudspeaker voice coil and described T-shaped conducting magnet core post.
Further, described support member is annular.
Further, described support member is multi-point support post.
Further, described high pitch metal vibration diaphragm top is the one in cancave cambered surface, convex globoidal, plane.
Further, described high pitch metal vibration diaphragm top is provided with perforate.
Implement the embodiment of the present invention, have the advantages that and widen loudspeaker pronunciation frequency band by arranging high pitch metal vibration diaphragm, reduce audio distortions, it is not necessary to frequency divider, treble portion coil, there is not the situation that high pitch voice coil loudspeaker voice coil burns, simple in construction, economical and practical.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the present invention；
Fig. 2 is the partial enlargement structural representation illustrating A portion in Fig. 1.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is described in further detail.
Overall structure schematic diagram with reference to the present invention shown in Fig. 1.
In embodiments of the present invention, including frame 10, bass vibrating diaphragm 20, voice coil loudspeaker voice coil 30, high pitch metal vibration diaphragm 40, ripple support 50, T-shaped magnetic conduction ferrum 60, ring magneto conducting piece 70 are played；Bass vibrating diaphragm 20 one end is connected with frame 10, and the other end is connected with voice coil loudspeaker voice coil 30 and bullet ripple support 50, and voice coil loudspeaker voice coil is arranged at T-shaped magnetic conduction ferrum and constitutes bass unit in the gapped magnetic field of ring magneto conducting piece 70 formation；And support member 602 is set on T-shaped conducting magnet core post 601, and by supported and suspended for high pitch metal vibration diaphragm 40 gapped magnetic field being arranged between voice coil loudspeaker voice coil 30 and T-shaped conducting magnet core post 601, structural representation as shown in Figure 2.
The cross section of high pitch metal vibration diaphragm 40 is n shape, and its top cover inwall is fixing with support member 602 to be connected, and the ring wall of formation hangs and is arranged in the gapped magnetic field between voice coil loudspeaker voice coil 30 and T-shaped conducting magnet core post 601, forms voice unit.
In the present embodiment, support member 602 is annular wall, and certain support member 602 is alternatively some support column, and the embodiment of the present invention is not limited.
High pitch metal vibration diaphragm 40 top can be the one in cancave cambered surface, convex globoidal or plane, and the preferred convex globoidal of the present embodiment illustrates, as shown in Figure 1.
As further improvement of this embodiment, high pitch metal vibration diaphragm 40 top in n shape is provided with a perforate.
The embodiment of the present invention is in order to overcome the deficiency of existing background technology, conventional horn is improved by the present invention, gapped magnetic field between voice coil loudspeaker voice coil and T-shaped conducting magnet core post adds high pitch metal vibration diaphragm, form voice unit, the spread spectrum loudspeaker making the present invention are not required to use frequency divider, remain to realize wideband playback, its part-frequency point places one's entire reliance upon the physical characteristic of high pitch metal vibration diaphragm itself and electromagnetic induction characteristic and Natural regulation, thus widen the acoustic frequency response scope of the most single loudspeaker, promote loudspeaker entirety result of broadcast.
The present invention is to use electromagnetic induction principle, when tone currents sends into voice coil loudspeaker voice coil 30, and voice coil loudspeaker voice coil 30 moves in magnetic field with the change of tone currents and drives bass vibrating diaphragm 20 to send medium and low frequency sound.Due to the restriction of vibrated membrane material, high-frequency sound is then responded poor by bass vibrating diaphragm 20.Meanwhile, high pitch metal vibration diaphragm 40 is placed in the part in the gapped magnetic field between voice coil loudspeaker voice coil and T-shaped conducting magnet core post, is sensed by the high frequency electric of voice coil loudspeaker voice coil 30 and obtains high-frequency energy, produces vibration, make high pitch metal vibration diaphragm send high-frequency sound.The utilization of above-mentioned principle, just allows height, medium and low frequency section audio signal each respond in bass unit at the voice unit constituting the present invention, the sounding body of composition wideband.
Needing to illustrate, high pitch metal vibration diaphragm of the present invention is not only suitable for external magnetic structural speaker, is also applied for internal magnetization structure loudspeaker, and the present invention is to select external magnetic structural speaker to illustrate.
The above is the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, on the premise of using principle without departing from the present invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
