Vibration Massage: Controls and Model Data

A published vibration function identifies mechanical oscillation, while a control count needs its own scope. T1 lists motor vibration and three speed levels, making the speed count directly relevant to its operating choices. F20 lists pulse, vibration and heating with ten modes and sixteen intensity levels. Those combined-function controls do not establish sixteen measured vibration amplitudes. Y8 also identifies motor vibration alongside airbag, heat and Bluetooth music. None of these records publishes vibration frequency in hertz or displacement in millimetres. The absence matters because a level on one product is not a common unit shared with another product. Different housings, contact materials and motor arrangements can transmit motion differently even at similar drive speeds.

Frequency, displacement and contact design describe different aspects of a vibration experience. Frequency is how often motion repeats; displacement is the distance of that motion; the contact interface influences how it reaches the user. A motor may create vibration through an eccentric rotating mass or another construction, but the current records do not disclose that assembly in model-level detail. They also do not provide a standardized loaded measurement. Consequently, the phrase multi-frequency in a feature list cannot become an invented hertz range, and a device's rated electrical power is not a direct measure of felt vibration. For a retailer, the defensible description is the published mechanism and available operating choices.
