A method of correcting a resonance frequency in a vibration speaker generating acoustic sound and vibration includes adjusting the actual resonance frequency to a higher resonance frequency by limiting a predetermined portion of an elastic member installed in a case to an inside of the case to increase the resonance frequency when the actual resonance frequency is not identical to nor less than the desired resonance frequency, thereby adjusting an actual resonance frequency to be identical to a desired resonance frequency, and adjusting the actual resonance frequency to a lower resonance frequency by cutting off another predetermined portion of the elastic member to decrease the resonance frequency when the actual resonance frequency is not identical to nor greater than the desired resonance frequency, thereby adjusting an actual resonance frequency to be identical to a desired resonance frequency. In the vibration speaker, the actual resonance frequency is corrected to the desired resonance frequency, thereby reducing a defect of the vibration speaker.
A resonance frequency correcting method in a vibration speaker having a case and an elastic member disposed in the case, the method comprising:
