The present invention discloses a multi-wave signal keep-fit energy chamber. The keep-fit energy chamber is a multi-wave signal emission chamber, 90-150 multi-wave signal emission elements (37) are uniformly distributed in the chamber. The multi-wave signal emission elements (37) are subjected to signal modulation through a multi-wave signal modulation power supply (33) under the action of an electric field and emit a multiple waveforms corresponding to a human body so as to enable the human body to generate multi-wave resonance in the chamber, thereby achieving the effects of eliminating human diseases, promoting health, prolonging life and keeping fit. The multi-wave signal modulation power supply (33) manufactured by using a method for manufacturing the multi-wave signal modulation power supply (33) is used for the multi-wave signal keep-fit energy chamber.
