Embodiment Construction
[0028] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that these embodiments may be practiced without these specific details.
[0029] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0030] In the following description, for the purpose of illustration, in the following description of specific embodiments of the present invention, the rigid part at the center of the diaphragm is collectively expressed as the word "DOME".
[0031] It should be noted that in the present invention, the method of multi-diaphragm is used to increase the radiation area of ββthe loudspeaker. Therefore, the diaphragms at odd and even positions are respectively connected through external connecting rods to form two groups of diaphragms, and the diaphragms of each diaphragm ...

Abstract
The invention provides a multi-diaphragm loudspeaker which comprises at least four diaphragms, inner connecting rods, outer connecting rods, driving sources and centering disks. The diaphragms positioned at odd positions are mutually connected through the inner connecting rods to form a first diaphragm group, the inner connecting rods for connecting the diaphragms positioned at the odd positions are connected through the outer connecting rods, the diaphragms positioned at even positions are mutually connected through the inner connecting rods to form a second diaphragm group, the inner connecting rods for connecting the diaphragms positioned at the even positions are connected through the outer connecting rods, the driving sources are positioned at two ends of the multi-diaphragm loudspeaker, each driving source respectively drives the first diaphragm group and the second diaphragm group, the centering disks are fitted on a DOME of each diaphragm in the first diaphragm group far away from a first magnetic circuit and on a DOME of each diaphragm in the second diaphragm group far away from a second magnetic circuit respectively. By the aid of the multi-diaphragm loudspeaker, polarization of an existing loudspeaker can be effectively suppressed by the centering disks.
Description
technical field [0001] The present invention relates to the technical field of acoustic-electric conversion, and more specifically, relates to a multi-diaphragm loudspeaker. Background technique [0002] The loudspeaker is one of the most critical components in the audio equipment, and it is the most important component for the sound effect. There are many kinds of loudspeakers, and the audio electric energy makes its paper cone or diaphragm vibrate and resonate (resonate) with the surrounding air through electromagnetic, piezoelectric or electrostatic effects to produce sound. [0003] A loudspeaker with a traditional structure includes a diaphragm and a drive unit. Wherein, the drive unit includes a damper, which is usually placed under the first diaphragm, and the damper is used to suppress the polarization of the product. Usually several circular diaphragms are used, and the connecting rod passes through the several diaphragms and connects them together; Modulation, h...
