The protrusion 603 protrudes from the massage head member main body 601 toward one side away from the substrate 100 (refer to
The user controls each of the massage head members 600 by controlling each of the driving assemblies 200 by the controller 901 to allow the plurality of massage head members 600 to operate asynchronously, so that various massage modes are provided.
For example, when the controller 901 is configured to control the two drive assemblies 200 to rotate, the two massage head member main bodies 601 may synchronously rotate the respective protrusions 603 in opposite directions about the axes of the respective massage head member main bodies 601. Accordingly, the controller 901 causes the two protrusions 603 to rotate symmetrically (refer to
In another example, when the controller 901 control the operation of the two drive assemblies 200, the two protrusions 603 are located at different positions which are independent from each other (see

When the massage function is activated, the plurality of massage head members 600 start to move synchronously or intermittently for a predetermined distance in the axial direction under the control of the controller, providing a plurality of massage modes.
