Abstract
The utility model provides a multifunction sound generator, comprising a sound generating system, a vibrating system, and an auxiliary system, wherein the vibrating system comprises a vibrator, the auxiliary system comprises a cone frame containing the sound generating system and the vibrating system, a magnet opposite to the inner wall of the cone frame is embedded on the vibrator, magnetic fluid is adsorbed into the clearance between the magnet and the cone frame. Compared with the prior art, the multifunction sound generator of the utility model adsorbs the magnetic fluid and thereby forming strong damp when vibrating, obtaining more wide vibrating band, without infecting acoustic performance of the sound generating system (loudspeaker system).
Description
[technical field]
The utility model relates to a kind of multi-functional acoustical generator, especially relates to a kind of vibrational system structure of multi-functional acoustical generator.
[background technology]
In the process of portable equipment fast developments such as mobile phone, people are more and more stronger to the functional requirement of product, this function of Music Appreciation for mobile phone, in order to make entertainment effect stronger, the pattern that the music belt vibration occurred, thus, the particularly also corresponding quickening of development of the vibrator part of miniature electro-acoustic device of miniature electro-acoustic device.
As shown in Figure 1, existing multi-functional acoustical generator comprises auxiliary system, sonification system (being speaker system), vibrational system (being vibrator system).Described auxiliary system comprises: protecgulum 11 and bonnet 12 that basin frame 10, basin frame link to each other.Described vibrational system comprises: be supported on latch plate 13 in the basin frame 10, be suspended on oscillator 14 on the latch plate, be contained in the oscillator and form the permanent magnet 15 and the pole piece 16 of magnetic gap with oscillator.Described sonification system comprises: be connected to vibrating diaphragm 17 on the basin frame with protecgulum 11, link to each other with vibrating diaphragm and be suspended in the voice coil loudspeaker voice coil 18 in the magnetic gap.This series products is when vibration, and vibrational system mainly provides damping by the air a between oscillator 14 and the basin frame 10.Because the viscous damping coefficient of air is very little, make that to bear the power that vibrational system is born when more high-power at multi-functional acoustical generator less, in the time of the product playing back music, since in the multi-functional microphone device during the very big and low frequency part of speaker system power loud speaker and vibrator system can work simultaneously, can produce very strong noise this moment, thereby the product mode of operation was lost efficacy.In order to overcome this deficiency, as shown in Figure 2, magnetic fluid 19 is set up forming strong damping in the gap between pole piece 16 and voice coil loudspeaker voice coil 18, and promptly the low frequency performance of (sonification system) is very poor but this structure but can cause speaker system.
Therefore, be necessary the vibrational system structure of multi-functional acoustical generator is proposed the requirement of innovation.
[utility model content]
The technical problem that the utility model need solve is to overcome above-mentioned deficiency, and a kind of vibration bandwidth and well behaved multi-functional acoustical generator are provided.
According to the above-mentioned technical problem that needs solution, designed a kind of multi-functional acoustical generator, comprise sonification system, vibrational system, auxiliary system, described vibrational system comprises oscillator, described auxiliary system comprises the basin frame of accommodating sonification system and vibrational system, on oscillator, be embedded with and the relative magnet of basin frame inwall, in the gap of magnet and basin frame inwall, be adsorbed with magnetic fluid.
Further improve as the utility model, be surrounded with magnet in one week of periphery of oscillator.
Further improve as the utility model, be respectively equipped with magnet at four ends of oscillator, magnet is " ten " font and distributes.
Further improve as the utility model, be respectively equipped with magnet along diametric two ends at oscillator.
Compared with prior art, the multi-functional acoustical generator of the utility model is installed magnet on oscillator, by magnet absorption magnetic fluid is arranged, thereby forms strong damping and can obtain wideer vibration frequency band when vibration, simultaneously, can not influence the acoustical behavior of sonification system (being speaker system) yet.

[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
As shown in Figure 3 and Figure 4, the multi-functional acoustical generator 200 of the utility model comprises auxiliary system, sonification system, vibrational system.Auxiliary system is used to accommodate and supports sonification system and vibrational system, and it comprises: basin frame 20, protecgulum 21, bonnet 22.Vibrational system, promptly vibrative vibrator structure unit, it comprises: latch plate 23, permanent magnet 24, pole piece 25, oscillator 26.Sonification system, the loadspeaker structure unit of promptly sounding, it comprises: vibrating diaphragm 27, voice coil loudspeaker voice coil 28.
The utility model oscillator 26 is bowl-shape, in fact is equivalent to the magnet frame and integrally formed the forming of mass that is looped around the magnet frame bottom of common structure.The utility model execution mode is embedded with magnet steel 29 at oscillator respectively along diametric two ends, simultaneously, another execution mode of the utility model also can be surrounded with magnet in one week of periphery of oscillator or be respectively equipped with at four ends of oscillator and be the magnet that " ten " font distributes.Magnet steel 29 is relative with the inwall of basin frame 2, forms the gap therebetween.Form strong damping in order to make when vibrating, the multi-functional acoustical generator of the utility model is filled with magnetic fluid 30 in this gap.This structure also can make the multi-functional acoustical generator of the utility model obtain wideer vibration frequency band, simultaneously, also can not influence the acoustical behavior of sonification system (being speaker system).
The utility model also can be by regulating the size that gap length, magnetic fluid volume and viscosity are regulated damping.
More than the assembly relation of each parts as follows: latch plate 23 is supported in the accepting hole of basin frame 20, oscillator 26 is suspended on the spring, permanent magnet 24 and pole piece 25 are contained in the oscillator 26 and with oscillator and form magnetic gap, voice coil loudspeaker voice coil 28 suspend with magnetic gap in, and link to each other with vibrating diaphragm 27, vibrating diaphragm 27 is connected on the upper surface of basin frame 20 with protecgulum 21, and bonnet 22 links to each other with the lower surface of basin frame 20.
Above-described only is execution mode of the present utility model; should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the utility model creation design; can also make improvement, but these all belong to protection range of the present utility model.
