Description
Technical field
This utility model relates to technical field of motors, particularly relates to a kind of linear vibration electric motor.
Background technology
Vibrating motor is also vibrating motor, and vibrating motor is the indispensable electronic devices and components of electronic product such as mobile phone, panel computer, electronic toy, and it provides the user sense of touch feedback.Intensified competition along with smart mobile phone market, user's tactile experience is increasingly paid close attention to by mobile phone producer, market occurs in that the linear vibration motor of the various structure in district, compared to conventional rotors motor, linear motor has very big advantage in vibration characteristics, response time, service life, noise etc., and it is provided that multiple vibration mode, provide the user rich and varied and fine and smooth sense of touch feedback true to nature.Current vibration-type linear motor internal structure is widely different, each own pluses and minuses in motor characteristics.Some linear vibration electric motor vibration sense is strong, but internal structure is complicated, and parts are a lot, it is high to manufacture difficulty cost, although some linear vibration electric motor is less costly, but vibration sense is more weak, poor-performing.How to produce simple in construction, cost linear vibration electric motor low, superior performance is the emphasis in current vibrating motor field and difficult point.
Utility model content
This utility model is in order to solve linear vibration motor of the prior art or the problem of structure complexity manufacturing cost height or vibration sense difference, it is provided that a kind of compact conformation, volume are little, the disc spring type linear vibration electric motor structure that cost is low, vibration sense is strong.
To achieve these goals, this utility model adopts the following technical scheme that
A kind of disc spring type linear vibration electric motor structure, including upper shell, lower house, the inner bottom part of described lower house is provided with circuit board, one end of circuit board is stretched out outside lower house, the bottom center of described lower house is provided with the coil being connected with circuit board, the surface of described coil is provided with annular magnet frame, described annular magnet frame opening down, the axis of annular magnet frame and the axis coaxle of coil, the inner side of described annular magnet frame is provided with magnet steel, annular chamber is formed between described magnet steel and annular magnet frame inwall, the upper end of described coil is positioned at annular chamber, the outside of described annular magnetic steel is provided with mass, it is provided with disc spring between described mass and lower house, the upper surface of described mass is coplanar with the upper surface of annular magnet frame, it is provided with between upper surface and the inner bottom surface of upper shell of described mass and dodges gap.Whole linear vibration electric motor compact conformation, coil, circuit board are fixed, annular magnet frame, magnet steel, mass constitute oscillator, the electric field of mechanical periodicity is produced after coil electricity, oscillator vibrates because of electromagnetic induction, disc spring connects oscillator and casing, thus the vibration of oscillator is passed to joint outer part, so that mobile phone, panel computer, electronic toy etc. produce vibration sense.
As preferably, described disc spring include disc spring inner ring, disc spring outer ring, for connecting some nonrigid connectors of disc spring inner ring and disc spring outer ring, described disc spring inner ring is fixing with the lower surface of mass to be connected, and described disc spring outer ring is connected with lower house；During naturalness, disc spring inner ring is higher than disc spring outer ring.Owing to disc spring self exists difference in height, therefore need not designing escape groove on mass, so in identical space, the quality of mass can increase, and vibration sense also can be strengthened.
As preferably, the edge of described disc spring outer ring is provided with some card ears, and the opening of described upper shell is provided with and card ear draw-in groove one to one, and when upper shell is connected with lower house, described card ear snaps in described draw-in groove.After upper shell is connected with lower house, disc spring just secures with upper shell, lower house, and assembly or disassembly is all very convenient.
As preferably, the edge of described mass is circumferentially arranged with some guiding gutters running through the upper and lower two ends of mass.In order to reduce the overall dimensions of vibrating motor, when design, the gap between side and the upper enclosure inner wall of mass is all only small, when mass up-down vibration, mass upper air, lower air can along Clearance Flow after being squeezed, owing to gap is less, therefore during mass vibration, air damping is bigger, vibration sense can be weakened, this structure designs guiding gutter on mass, mass can quickly regulate the flowing of upper air, lower air when vibration, thus weakening the air damping impact on mass.
As preferably, the bottom center of described lower house is provided with some steam vents, and the outer bottom of described lower house is provided with the dustcloth that steam vent is completely covered.Can cause when mass vibration that the air within vibrating motor is discharged from steam vent or sucks, it is thus possible to strengthen the heat dispersion of vibrating motor, improve service life；Dustcloth can prevent dust from entering inside vibrating motor.
Therefore, this utility model has that compact conformation, volume are little, the beneficial effect that cost is low, vibration sense is strong.
