What are the applications of rubber-plastic shock absorbers in consumer electronics?

Rubber-plastic shock absorbers, with the characteristics of light weight, good elasticity, noise reduction, vibration isolation and aging resistance, play a core role in protecting internal components, improving the use feel and prolonging the service life of equipment in the field of consumer electronics. The specific application scenarios cover mainstream products such as mobile phones, notebook computers, headphones and smart home equipment, and the breakdown categories and functions are as follows:

Smartphones and tablets

Lens damping pad: made of silicone or TPE, it is attached between the camera module and the middle frame to cushion the impact force during falling and collision, prevent the lens from shifting or the glass from breaking, and reduce the influence of the vibration of the camera body on the imaging clarity when taking pictures.

Battery shock-absorbing foam: mostly made of EVA or silicone foam, wrapped around the battery to absorb the shaking and impact in daily use, avoid the risk of short circuit caused by hard contact between the battery and the motherboard and middle frame, and adapt to complex working conditions such as falling and squeezing of the mobile phone.

Loudspeaker/earpiece damping ring: annular silicone or TPE parts, which fix the loudspeaker module, isolate the vibration conduction during sounding, reduce the noise generated by fuselage resonance, and improve the purity of audio playback.

Notebook computer and two-in-one device

Rotating shaft damping shock absorber: TPE or silicone composite material is adopted and integrated in the rotating shaft structure of the screen and the fuselage. By accurately controlling the damping coefficient, the screen is smooth and smooth when opening and closing, avoiding the collision and damage of parts caused by too fast opening and closing, and absorbing the vibration and noise when the rotating shaft rotates.

Hard disk shock absorber: a frame structure with rubber or silica gel as the base material, which is sleeved outside the mechanical hard disk, absorbs the vibration of the hard disk when it runs at high speed, reduces the noise, and prevents the vibration from being transmitted to the motherboard to affect the stability of other components, especially suitable for high-performance equipment such as game books.

Keyboard cushion shock-absorbing cotton: ultra-thin EVA or silicone foam is attached to the bottom of the keyboard panel to cushion the impact force when the keys are pressed, reduce the abnormal sound when the keys rebound, improve the typing feel, and isolate the transmission of keyboard vibration to the fuselage.

Headphones and audio equipment

Headbeam shock absorber for headphones: made of memory sponge or silicone foam, filled in the joint between the headbeam and the earmuffs, to cushion the pressure when wearing, adapt to the fit of different head types, and absorb the vibration when the earmuffs sound, so as to reduce the sound leakage and resonance noise.

Shock absorber for TWS charging bin: micro silica gel or TPE gasket, which is placed inside the charging bin to fix the earphone body, to avoid scratches and damage caused by collision between the earphone and the bin during opening and closing the charging bin or carrying, and to buffer the impact of vibration on the earphone battery and circuit board.

Speaker damping foot pad: a round/square foot pad made of silicone or rubber, which is attached to the bottom of the portable speaker to isolate the transmission of vibration from the speaker to the desktop, reduce the noise generated by desktop resonance, and improve the low-frequency sound quality performance.

Smart Home and Portable Electronic Equipment

Shock-absorbing protective sleeve for smart watches: an integrated protective sleeve made of silicone material, which wraps the watch body, cushions the impact force when falling and colliding, absorbs the vibration in daily wear, and protects the screen and internal sensors.

Cushion pad for projector: rubber or silica gel anti-slip cushion is placed at the bottom of the projector to absorb the vibration of the fan when the equipment is running, reduce the noise and prevent the projector from affecting the stability of the projection picture due to vibration displacement.

Joystick rocker damping ring: micro silicone ring is sleeved on the outer side of the rocker shaft to buffer the rocking of the rocker during operation, improve the control accuracy, reduce the abnormal noise caused by the friction between the rocker and the shell, and prolong the service life of the rocker.
