PURPOSE: A white noise generator is provided to output an excellent white noise using an inexpensive material without an expensive manufacturing facility. CONSTITUTION: A white noise generator (10) includes a memory part, an interface part (300), a speaker part (400), a resonance managing part (500), and a control part. The memory part stores a predetermined sound source. The interface part at the outer surface of the generator selects at least one of the sound source or whether or not an electric current is applied according to the switch control of a user. The speaker at one side of the generator amplifies and outputs the selected sound source so that the user is capable of hearing the sound source. The resonance managing part is formed along the outer circumferential edge of the speaker part at a predetermined height, and removes a high-frequency component in the sound source from the speaker part. The control part links the interface part with the memory part, and adjusts the output amount or the sound field of the speaker part.
