Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
The profile of the earphone speaker that Fig. 2 provides for the embodiment of the present invention, the earphone speaker of the present embodiment is particularly suited for In-Ear Headphones.
As shown in Figure 2, earphone speaker in Fig. 2 includes: support 2 and be housed in the magnetic circuit system within support 2 and vibrational system, magnetic circuit system is the toroid that T ferrum 6, annular magnet 5 and annular washer 3 are formed, and wherein annular washer 3 and T ferrum 6 constitutes the magnetic circuit gap of annular;
Concrete, with reference to shown in Fig. 2, T ferrum 6 includes circular bottom plate and the post core vertical with circular bottom plate center, annular magnet 5 and annular washer 3 concentric are around post core, and annular magnet 5 is arranged in circular bottom plate, and having gap with post core sidewall, annular washer 3 is arranged on annular magnet 5, annular washer 3 and post core sidewall constitute the magnetic circuit gap of annular, i.e. T ferrum 6, annular magnet 5 and annular washer 3 form a toroid.
Vibrational system in Fig. 2 includes vibrating diaphragm 1, voice coil loudspeaker voice coil 4, and voice coil loudspeaker voice coil 4 is bonded on vibrating diaphragm 1, and is suspended in the magnetic circuit gap of annular;Vibrating diaphragm 1 is positioned at the top of magnetic circuit system, and the edge of vibrating diaphragm 1 is fixed on support 2, and the mid portion of vibrating diaphragm 1 is fixed on T ferrum 6.
It should be noted that, in order to be fixed on T ferrum 6 by vibrating diaphragm mid portion, in the design process, the height of T iron prop core should be increased so that vibrating diaphragm core is pasted onto on post core, and other of magnetic circuit system are also sized to change therewith, to ensure the symmetry of magnetic circuit system.
Preferably, above-mentioned vibrational system also includes that pad 7, pad 7 are arranged on the upper surface of T ferrum 6 to the present embodiment, and the mid portion of vibrating diaphragm 1 is fixed on T ferrum 6 by pad 7.As in figure 2 it is shown, when vibrational system includes pad 7, pad 7 is arranged on the upper surface of the post core of T ferrum 6, the mid portion of vibrating diaphragm 1 is pasted onto on pad 7.
It should be noted that in this preferred version, owing to vibrational system with the addition of again pad 7, fix vibrating diaphragm by pad 7, thus this preferred version be without increasing the height of T iron prop core, it is not required that change other sizes of magnetic circuit system.In the design process of speaker, can choose whether to add pad according to application demand.
The present embodiment, by being fixed on the pad above T ferrum by the mid portion of vibrating diaphragm, increases the stiffness of vibrating diaphragm root, thus improves the upper limit and the width of playback frequency band that earphone speaker high frequency is reset, reduce the distortion that diaphagras produces, improve earphone speaker.
Owing to traditional In-Ear Headphones speaker leaves small holes the most overleaf, air can not get fully revealing, and affects tonequality.For this problem, one implementation of the present embodiment, mid portion at T ferrum 6 arranges through hole 61, pad 7 is set to annular gasket, and it is not provided with vibrating diaphragm 1 in just position to through hole 61, to reduce air damping, increase pliable, make the vibrational state of vibrating diaphragm more free, and then make the sound of earphone speaker the softest.
Wherein, the internal diameter of annular gasket is suitable with the diameter of through hole 61, as shown in Figure 2, the external diameter of annular gasket is less than the diameter of T iron prop core, to ensure the effective area of diaphragm oscillations, the internal diameter of annular gasket is slightly less than the diameter of through hole, to ensure the degree of stability that vibrating diaphragm mid portion is pasted, does not the most affect the circulation of air.
The implementation of the present embodiment provides a kind of novel leakage mode for earphone speaker, by arranging through hole at the mid portion of T ferrum, and just the position of through hole is being not provided with vibrating diaphragm, reduce air damping, increase pliable, diaphragm oscillations state is freer, it is thus possible to the sound making earphone speaker is the softest, decreases the difficulty of later stage tuning work.
In another implementation of the present embodiment, earphone speaker also includes: phase plug 8, and the bottom of phase plug 8 is fixed on the support 2 above vibrating diaphragm 1 radiating surface, top just through hole 61 to T ferrum 6, and has setpoint distance with pad 7.
Phase plug 8 in this implementation is diffusion type structure, including bullet-type phase plug and mushroom hair style phase plug.As in figure 2 it is shown, in Fig. 2 as a example by bullet-type phase plug, be fixed on the arc support 9 above diaphragm radiation face by inverted bullet-type phase plug, to change propagation path and the phase place of vibrating diaphragm surrounding sound wave, improve the sound field directivity of speaker, reduce distortion.
Wherein, in the design phase, can the individually designed arc support part for stationary phase plug, the arc support 9 in the most individually designed Fig. 2, this arc support 9 is fixedly installed on support 2, to simplify the difficulty of processing of support.Certainly, can also one-body molded arc support 9 and support 2 in the design phase.
In sum, the invention provides a kind of earphone speaker, the present invention is by being fixed on the mid portion of vibrating diaphragm on the pad above T ferrum, increase the stiffness of vibrating diaphragm root, improve the upper limit and the width of earphone speaker playback frequency band that earphone speaker high frequency is reset, thus decrease the distortion that diaphagras produces.And in a preferred approach, the present invention is by arranging through hole at the mid portion of T ferrum, and just the position of through hole is being not provided with vibrating diaphragm, and to reduce air damping, the sound making earphone speaker is the softest;And by setting up phase plug on the support above diaphragm radiation face, change propagation path and the phase place of vibrating diaphragm surrounding sound wave, to improve the sound field directivity of earphone speaker, reduce distortion further.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit protection scope of the present invention.All any modification, equivalent substitution and improvement etc. made within the spirit and principles in the present invention, are all contained in protection scope of the present invention.
