Description
Technical field
The utility model relates to electro-acoustic product technical field, particularly a kind of loud speaker.
Background technology
Loud speaker is a kind of energy conversion device, is commonly called as loudspeaker, for completing the conversion between the signal of telecommunication and voice signal, is the important acoustic element in sounding electronic electric equipment.Under normal circumstances, loud speaker comprises shell and the driver element that is fixed on shell and vibration unit, and vibration unit is made up of the cone of taper and the ring of annular.Because cone is pyramidal structure, make the integral thickness of loud speaker comparatively large, but the installing space that some electronic electric equipment leaves loud speaker for is less, the loud speaker that thickness is larger cannot be installed in these electronic electric equipments.So, the oscillating plate of a slab construction can be adopted to replace existing taper cone technical staff sometimes, this method effectively reduces the thickness of loud speaker really, but, this plate shaped oscillating plate will be fixed near the marginal position of oscillating plate with regard to needing voice coil loudspeaker voice coil in conjunction with a driver element, thus cause the central part intensity of oscillating plate more weak, diaphagras can be produced when low-frequency range, thus make loud speaker no longer level and smooth in the frequency response of low-frequency range, produce distortion, cause adopting the speaker sound quality of plate shape vibration plate poor, the integral thickness of loud speaker and sound quality can not be taken into account.
Utility model content
For above defect, technical problem to be solved in the utility model is to provide a kind of loud speaker, and this loud speaker, while not increasing integral thickness, improves the intensity of tabular oscillating plate, improves sound quality.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of loud speaker, comprise the shell of an open at one end, the opening end of described shell combines with the outward flange of a ring, the inward flange of described ring is connected with oscillating plate, described oscillating plate is slab construction, also comprises multiple driver element, and each described driver element includes magnetic circuit system and drives voice coil loudspeaker voice coil, one end of described driving voice coil loudspeaker voice coil is positioned at the magnetic gap of described magnetic circuit system, and the other end of described driving voice coil loudspeaker voice coil is fixed on described oscillating plate; On described oscillating plate, the position of corresponding each described driver element is respectively equipped with reinforcement part, and each described reinforcement part is raised or sunken perpendicular to described oscillating plate plane of bearing of trend.
Wherein, described driver element is provided with three, three described driver element distributions triangular in shape.
Wherein, the position of the corresponding each described driver element in bottom of described shell is provided with installing hole, and the described magnetic circuit system of each described driver element is positioned at described installing hole place, and the exposed outside at described shell.
Wherein, described magnetic circuit system comprises the frame of the bottom being fixed on described shell, is fixed with magnet and washer successively in described frame, is provided with described magnetic gap between the sidewall of described magnet and described washer and described frame.
Wherein, the inner surface of the bottom of described shell and the end face of described frame.
Wherein, described shell is circular configuration, and each described driver element is also circular configuration.
Wherein, each described reinforcement part is spherical surface hill or depression.
Wherein, the diameter of the edge part of described spherical surface hill and the diameter of described driving voice coil loudspeaker voice coil suitable.
After have employed technique scheme, the beneficial effects of the utility model are:
Because the utility model loud speaker comprises multiple driver element, and on tabular oscillating plate, the position of corresponding each driver element is provided with raised or sunken reinforcement part.Multiple driver element makes oscillating plate can vibrate in the middle part of it when vibrating simultaneously, there will not be the diaphagras that the center intensity because of oscillating plate of the prior art weak and itself vibrates time difference etc. produces; And the increase of reinforcement part, further enhance the intensity of oscillating plate central part, thus effectively raise the frequency of diaphagras, improve the smoothness of loud speaker in the frequency response of low-frequency range, reducing distortion, effectively improving the sound quality of loud speaker when ensure that the integral thickness of loud speaker does not increase.
In sum, the utility model loud speaker solves the technical problem that in prior art, loud speaker integral thickness and sound quality can not be taken into account, the utility model loud speaker is not while increasing integral thickness, improve the intensity of tabular oscillating plate, reduce distortion, improve the sound quality of loud speaker.
