Description
Technical Field
The utility model relates to a speaker technical field, specifically speaking relates to a take many magnetism speakers of spill magnetic conduction board.
Background
At present, the magnetic conduction plate of a common micro loudspeaker adopts a flat plate structure, because the size of the micro loudspeaker is very thin, under the condition of high power, the vibration amplitude of a vibrating diaphragm and a voice coil can be larger, under the condition, because the lead-out wire part of the voice coil is suspended, the suspended part is easy to touch the magnetic conduction plate due to inertia in the vertical vibration process, and then noise is generated.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a take many magnetism speakers of spill magnetic conduction board has reduced the noise of speaker.
The utility model discloses a take many magnetism speakers of spill magnetic conduction board adopts technical scheme is:
a multi-magnetic loudspeaker with concave magnetic conductive plate comprises a vibrating diaphragm; a voice coil connected to the diaphragm; the magnetic circuit system comprises an upper magnetic conductive plate, a lower magnetic conductive plate, a main magnet and a plurality of side magnets, wherein the main magnet and the side magnets are arranged between the upper magnetic conductive plate and the lower magnetic conductive plate, the side magnets are arranged around the main magnet, a gap is formed between the main magnet and the side magnets, and the voice coil is positioned in the gap; and the upper surface of the lower magnetic conduction plate is provided with a groove corresponding to the suspended part of the leading-out wire of the voice coil.
Preferably, the voice coil is rectangular, and the main magnet is formed along with the voice coil.
Preferably, four sets of side magnets are arranged, and the four sets of side magnets are respectively arranged on four sides of the main magnet.
Preferably, the shape of the groove is formed along the suspended part of the lead-out wire of the voice coil.
As a preferred scheme, the number of the grooves is two, and the two grooves are arranged in a bilateral symmetry mode.
Preferably, a dust screen is arranged above the vibrating diaphragm.
The utility model discloses a take many magnetism speakers of spill magnetic conduction board's beneficial effect is: the upper surface of the lower magnetic conduction plate is provided with a groove, the groove corresponds to the suspended part of the lead-out wire of the voice coil, when the voice coil vibrates up and down, the suspended up and down vibration of the lead-out wire part of the voice coil can not contact the upper surface of the lower magnetic conduction plate, and therefore noise can not be generated, and therefore noise is effectively reduced.

Fig. 2 is a schematic structural diagram of a voice coil of a multi-magnetic speaker with concave magnetic conductive plates according to the present invention.
Detailed Description
The invention will be further elucidated and described with reference to the following embodiments and drawings in which:
referring to fig. 1, a multi-magnetic speaker with concave magnetic conductive plate includes a diaphragm 10, a voice coil 20, and a magnetic circuit system 30.
The voice coil 20 is connected to the diaphragm 10, and a dust screen 40 is disposed above the diaphragm 10. Specifically, the vibrating diaphragm 10 is mounted on the support 11, the vibrating diaphragm 10 is provided with a protecting cover 12, the vibrating diaphragm 10 is mounted on the support 11 through the protecting cover 12, and the dust screen 40 is disposed on the protecting cover 12.
The magnetic circuit system 30 includes an upper magnetic plate 31, a lower magnetic plate 32, a main magnet 33, and a plurality of side magnets 34. The main magnet 33 and the side magnet 34 are both disposed between the upper magnetic conductive plate 31 and the lower magnetic conductive plate 32. The plurality of side magnets 34 are disposed around the main magnet 33, and a gap is formed between the main magnet 33 and the plurality of side magnets 34, and the voice coil 20 is disposed in the gap.
Referring to fig. 1 and 2, a groove 321 corresponding to the suspending portion 22 of the extension wire 21 of the voice coil 20 is formed on the upper surface of the lower magnetic conductive plate 32. The recess 321 follows the overhang portion 22 of the lead-out wire of the voice coil 20.
In the above solution, the voice coil 20 is rectangular, and the main magnet 33 follows the voice coil 20. The side magnets 34 are provided in four groups, and the four groups of side magnets 34 are arranged on four sides of the main magnet 33.
In the above solution, two lead wires of the voice coil 20 are bent to form the suspension portion 22, and two grooves 321 are formed on the upper surface of the corresponding lower magnetic conductive plate 32. The two grooves 321 are arranged symmetrically.
The utility model discloses a take many magnetism speakers of spill magnetic conduction board sets up recess 321 at magnetic conduction board 32 upper surface down, and recess 321 corresponds with the unsettled part 22 of voice coil loudspeaker voice coil 20 lead-out wire, and when voice coil loudspeaker voice coil 20 vibrates from top to bottom, the unsettled vibrations of voice coil loudspeaker voice coil 20 lead-out wire portion also can not contact magnetic conduction board 32 upper surface down, can not consequently produce the noise, so effectively reduced the noise.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
