wherein the solenoid device includes an impact member contacted to a returning spring and configured to generate low frequency vibration waves; wherein the vibration micro motor includes a motor coupled to at least one rotatable metal member and configured to generate low-middle frequency vibration waves. ## Claims ### Claim 1 A system for generating low and low to middle-frequency vibration waves to emulate low and low to middle audio frequencies, comprising: an exciter device comprising a solenoid device located adjacent to a vibration micro motor; wherein the solenoid device comprises an impact member contacted to a returning spring and configured to generate low frequency vibration waves; wherein the vibration micro motor comprises a motor coupled to at least one rotatable metal member and configured to generate low-middle frequency vibration waves; and wherein the exciter device is placed on a mandibular vestibule of a user's mouth. ### Claim 2 (depends on 1) The system of claim 1, wherein the solenoid device comprises a first pivot coupled with the impact member and the returning spring surrounds the first pivot. ### Claim 3 (depends on 1) The system of claim 1, wherein the returning spring is compressed towards the impact member to activate the impact member to generate the low frequency vibration waves. ### Claim 4 (depends on 1) The system of claim 1, wherein the rotatable metal member is coupled with the motor through a second pivot and is rotating along the second pivot. ### Claim 5 (depends on 1) The system of claim 1, wherein the vibration micro motor comprises a pair of rotatable metal members coupled on two sides of the motor through a second pivot, wherein the rotatable metal members are rotated along the second pivot. ### Claim 6 (depends on 1) The system of claim 1, wherein the solenoid device and the vibration micro motor are located inside a waterproof compartment. ### Claim 7 (depends on 1) The system of claim 1, further comprising a Bluetooth module communicated with a converter and configured to receive external audio frequency from an external audio frequency source. ### Claim 8 (depends on 1) The system of claim 1, further comprising a battery module communicated with the exciter device to provide electronic power to the exciter device. ### Claim 9 (depends on 1) The system of claim 1, further comprising an accelerometer placed adjacent to occipital bones of the user to receive the low and low to middle-frequency vibration waves and to convey the low and low to middle-frequency vibration waves to an analyzer, wherein the analyzer is configured to analyze the low and low to middle-frequency vibration waves and generate a frequency spectrum report. ### Claim 10 (depends on 1) The system of claim 1, wherein the exciter device is placed on a mentolabial sulcus adjacent to a user's mouth. ### Claim 11 (depends on 7) The system of claim 7, wherein the converter is communicated with the solenoid device and the vibration micro motor to convert the external audio frequency to a responding voltage to activate low-frequency vibration waves and low-middle frequency vibration waves. ### Claim 12 (depends on 2) The system of claim 2, wherein the first pivot moves towards the impact member and moves away from the impact member to perform a back-and-forth movement. ### Claim 13 (depends on 1) The system of claim 1, wherein the returning spring is compressed towards the impact member and restored to its original form to perform a back-and-forth movement. ### Claim 14 (depends on 1) The system of claim 1, further comprising an audio band-pass filter communicated with the solenoid device and the vibration micro motor to extract low and low-middle external audio frequency from an external audio frequency generated from an external audio frequency source. ### Claim 15 (depends on 7) The system of claim 7, further comprising an audio power amplifier communicated with the Bluetooth module and configured to amplify the received external audio frequency.
