Description

Panel speaker

Technical field

The utility model relates to a kind of loud speaker, relates in particular to a kind ofly to have preferable sounding sensitivity and tonequality and avoid body to produce crooked panel speaker when motion.

Background technology

Along with industrial and commercial flourishing, people's living standard promotes day by day, for the quality of recreation and require also gradually towards exquisiter direction, for example: the auditory effect of sound, the visible change of light, become the indispensable project that promotes quality of life all, especially sound (music), the general especially emphasis that lies fallow, good and suitable music, for loosening mood, eliminate the nervous splendid effect that has, therefore, Xiang Guan acoustic product is a feast for the eyes especially on the market, and it is formal confused to make us dim eyesight, and in above-mentioned acoustic product, loud speaker is being born the function that the current signal of enlarger output is converted to sound, and its overall sound quality output quality for sound equipment has decisive influence.

In recent years, because various inhabitations or operational environment also are particular about whole vision impression, for cooperating various different purposes and environment, the outward appearance of loud speaker, shape and structure also have great difference, and wherein, panel speaker is a common loud speaker kind.

Existing panel speaker structure as shown in Figure 1, it establishes a magnetic core 11 in a housing 10, and in the sheathed pipe crimping 12 of these magnetic core 11 top peripheries, and be wound with voice coil loudspeaker voice coil 121 in this pipe crimping 12, and being the bullet ripple portion 13 of outside wavy extension in the end of facing magnetic core 11 and, this pipe crimping 12 combines, the end in addition of this pipe crimping 12 is cover unification meson 14 then, and fits in oscillating plate 15 table sides by this meson 14.The start principle of this panel speaker is mainly imported voice coil loudspeaker voice coil 121 with the output signal of enlarger, make it to produce magnetic field and magnetic core 11 interactions, and can make pipe crimping 12 and magnetic core 11 form relative reciprocating action, to promote oscillating plate 15 blow air and sounding via meson 14, yet the existing panel speaker of this kind has following shortcoming:

1, generally speaking sounding, compares with the loud speaker of traditional cone structure because it utilizes the vibration of oscillating plate 15, the mass inertia of oscillating plate 15 is bigger, lower drive current is difficult for making the vibration of the enough sounding of oscillating plate 15 generations, and therefore, the sounding sensitivity of its whole loud speaker is lower.

2,, if the position that this meson 14 is arranged on the oscillating plate 15 is inappropriate, then very easily make the integral planar vibration of oscillating plate 15 unequal, and then reduce the tonequality of its sounding because the mass inertia of aforementioned oscillating plate 15 is bigger, and energy attenuation speed is bigger.

3, because the mass inertia of aforementioned oscillating plate 15 is bigger, cause pipe crimping 12 to need to drive with great thrust, and pipe crimping 12 itself only plays ripple portion 13 as supporting with one, therefore, when the loud noise signal was exported, this pipe crimping 12 may produce the crooked of moment, so, the lighter may form the distortion of output sound, and severe patient then may produce the damage of loud speaker.

Therefore, in view of the above-mentioned problems, how to provide a kind of panel speaker, avoided the sounding sensitivity of whole panel speaker lower, sounding tonequality is relatively poor and problem such as pipe crimping underbraced, become the important topic that present anxious desire solves in fact.
