Abstract
The invention relates to the technical field of the sounder, particularly to a miniature moving-iron bone conduction driving device of a sounder. The miniature moving-iron bone conduction driving device comprises a supporting with installing through holes; and a magnetic cover and an annular voice coil arranged in the magnetic cover are arranged in one installing through hole of the support. A vibration spring plate is arranged at the support and is located in the other installing through hole; a magnetic steel is arranged at the vibration spring plate; a pole plate is fixedly arranged at the magnetic steel; and the magnetic steel and the pole plate are located in the space formed by enclosure of the voice coil. The traditional moving-coil type loudspeaker structure is changed into the moving-iron type structure; the driving force of the vibration system and the vibratory sensation during sounding can be enhanced; because of the driving plate, connection with a case can be realized conveniently, so that the sound can be conducted to the case and the sounding is carried out by the case; because the area of the case is far larger than the vibration area of the common loudspeaker, the effective vibration area is increased, thereby substantially improving the driven volume and the vibration sensation of the effective sound that is given out.
Description
Technical field
The present invention relates to acoustical generator technical field, be specifically related to a kind of miniature moving-iron type osteoacusis drive unit of acoustical generator.
Background technology
Perplex at present a difficult problem for acoustical generator industry always, the loud speaker of mobile phone, panel computer, notebook is due to the restriction of structure and the confined space, the volume of its generation is less, the problem that sense of hearing is poor, but along with mobile phone, panel computer do thinner and thinner, size is more and more less, the space of leaving loud speaker for is also more and more less, volume does not reach mobile phone always, and the requirement of the communication articles for use such as panel computer has also just reduced the result of use of product.
Summary of the invention
For above-mentioned technical problem, the invention provides one simple in structure, reasonable in design, can make loud speaker increase sounding area, increase the miniature moving-iron type osteoacusis drive unit of phonation volume.
Realize technical scheme of the present invention as follows:
Miniature moving-iron type osteoacusis drive unit, comprise and there is the support that through hole is installed, in the installation through hole of support, be provided with magnetic cover, and be arranged in magnetic cover voice coil loudspeaker voice coil in the form of a ring, on support, be provided with vibration shell fragment and in installing in through hole, on described vibration shell fragment, be provided with magnet steel, on magnet steel, be fixedly installed pole piece, in the space that described magnet steel and pole piece enclose in voice coil loudspeaker voice coil.
Further, on described vibration shell fragment, be fixedly installed driver plate.
Further, described driver plate middle part is provided with the through hole of perforation.
Further, the through hole that described support installation through hole is not waited by two diameters forms, and above-mentioned magnetic cover, voice coil loudspeaker voice coil are arranged in the through hole that diameter is little and the through hole one end keeping parallelism large with diameter, and described vibration shell fragment is arranged in the through hole that diameter is large.
Adopted such scheme, changed traditional coil-moving speaker structure, changed to moving-iron type, the vibratory sensation when increasing the motive force of vibrational system and increasing sounding; By the setting of driver plate, can be connected with casing very easily, like this can be by sound conduction to casing, by casing, sound, because the area of casing is far longer than the vibration area of ventional loudspeakers, thereby increased effective vibration area, greatly promoted institute and send effective sound drive volume and vibration sense.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
Referring to Fig. 1, miniature moving-iron type osteoacusis drive unit, comprise and there is the support 2 of through hole 1 of installation, in the installation through hole of support, be provided with magnetic cover 3, and be arranged in magnetic cover voice coil loudspeaker voice coil 4 in the form of a ring, on support, be provided with vibration shell fragment 5 and in installing in through hole 1, on vibration shell fragment 5, be provided with magnet steel 6, on magnet steel, be fixedly installed pole piece 7, during vibration, vibration shell fragment, magnet steel and pole piece vibrate together, in the space that magnet steel and pole piece enclose in voice coil loudspeaker voice coil.The through hole that support installation through hole is not waited by two diameters forms, and above-mentioned magnetic cover, voice coil loudspeaker voice coil are arranged in the through hole that diameter is little and the through hole one end keeping parallelism large with diameter, and vibration shell fragment is arranged in the through hole that diameter is large.On vibration shell fragment, be fixedly installed driver plate 8, driver plate middle part is provided with the through hole 9 of perforation.Driver plate when assembling with being connected of casing 10, and casing can be determined according to client's size, generally material is that ABS, ABS+PC, PC or metalwork are made.
At this, it should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make improvement, but these all belong to protection scope of the present invention.
