Description
Technical field
The present invention relates to vibrating motor technical fields, and in particular to a kind of Novel horizontal vibration horse with damping system
It reaches.
Background technique
Vibrating motor is the indispensable component of the electronic products such as mobile phone, tablet computer, handheld device, is
User provides touch feedback.With the intensified competition in smart phone market, mobile phone producer increasingly pays close attention to user's tactile experience,
Client is also higher and higher to the vibrational feedback effect of motor, thus occurs the linear vibration for being different from conventional rotors motor in the market
Dynamic motor.Compared to conventional rotors motor, linear motor vibration characteristics, the response time, service life, in terms of have
Very big advantage, and it can provide a variety of vibration modes, provide rich and varied and fine and smooth touch feedback true to nature for user.
The structure of X axis vibration linear motor is provided needed for motor vibrations generally by the way of: magnetic fluid (referred to as: magnetic liquid) at present
Damping, but with magnetic liquid provide damping mode have the shortcomings that one it is fatal: magnetic liquid is waited at high temperature, and viscosity can decline, and is led
It causes to fail to the displacement restriction effect of motor vibrator, so that motor is waited at high temperature easily there is oscillator shock casing inner wall,
Noise is generated, moreover, stress suffered by motor spring also steeply rises with the increase that oscillator is displaced, leads to the urgency of motor life
The case where play decline.
The coefficient of elasticity of spring is the parameter modulus for reflecting metal material in proportional limit.When stretching: E=σ/ε (Hooke
Law) in formula: σ tensile stress, ε stretching strain, E --- coefficient of elasticity；The testing of materials shows as the temperature rises, metal material
Tensile strength, yield strength and coefficient of elasticity decline.Elongation and shrinking percentage rise.When temperature becomes larger, spring
Elastic force reduces, and works long hours and is loading larger, the higher spring of temperature, it may occur that " deformation of creep " is plastically deformed, and is removed
Spring is by cannot return to the original form i.e. usually said " relaxation " when load, to the very harmful of equipment.Portable device
Radiating condition is usually poor, although vibrating motor calorific value is small, in the CPU of portable device internal, then calorific value is very
Greatly, cause portable device internal temperature much higher than room temperature.It can ignore in influence of the near room temperature temperature change to spring, but
In the case where portable device internal temperature is much higher than room temperature, this influence, which cannot be ignored, to be disregarded.
Chinese patent CN107276359A, publication date on October 20th, 2017, a kind of horizontal vibration motor, including shell,
