Blender whose operation presents a sound level lower than that of other equipment available in the market. This effect is obtained by the combination of construction details that when associated, result in a differential operation volume. The first construction detail is the design of the blender jar that facilitates the motion of the contents when the equipment is working. The second is presented in a system to absorb shocks during the transmission of the motor motion to the crushing blades, minimizing the vibration of the assembly. The third construction detail is the connection system of the motor with the transmission axle of the crushing blades that also helps the decrease of vibration of the equipment.
