Abstract: A signal transmitter with adjustable signal power includes a housing, a first adjustable metal shielding layer and a circuit board. The first adjustable metal shielding layer is disposed within the housing. The area of the first adjustable metal shielding layer consists of a first shielding area and a first un-shielding area. The first shielding area and the first un-shielding area are adjustable. The circuit board is disposed within the housing, and is located below the first adjustable metal shielding layer. The circuit board is electrically connected with the first adjustable metal shielding layer, and includes a signal emission chip. The signal emission chip is configured for adjusting signal emission power to emit a signal according to the first un-shielding area of the first adjustable metal shielding layer. A message generating system and a signal power adjusting method are disclosed herein as well.
