AUSTRALIA Patents Act 1990 BEAUNIX CO., LTD. COMPLETE SPECIFICATION STANDARD PATENT Invention Title: Music-synchronized low frequency stimulator The following statement is a full description of this invention including the best method of performing it known to us:- BACKGROUND OF THE INVENTION 1. Field of the Invention 5 The present invention relates to a music--synchronized low frequency stimulator, and in particular, to a music-synchronized low frequency stimulator that is capable of stimulating and medically curing the nerves of a certain portion of a human body by outputting music such as classical music, pop song, folk song, etc. and generating a low frequency electric pulse in synchronization with the outputted 10 music. 2. Description of the Background Art Generally, people listen to music and sing using a cassette tape recorder, a CD, a broadcast station of AM/FM, an audio device, an MP3 player, a sound 15 output device such as Karaoke, etc. According to a study in psychoanalysis, a person feels the most peace and comfort in a mother's amniotic fluid pocket. In music therapy, it is known that water-based music largely influences human health. When a person is tired of studying or feels stress, listening to music such as Reflets dans l'eau by Claude Debussy, Jeux d'Eau by M. Ravel, water music by 20 Handel, etc. or to record the sounds of water or nature and listen to the same is said to help provide rest and energy to the body and mind. In addition, it is known that life activity or social life of a person has a certain cycle. Here, riding the above cycle is called "String" which is a technical term. When a person listens to a waltz, the person may feel a massage effect as 25 dynamic rhythm is well matched with the tired mind and body. When a person 1A listens to Sabre Dance by Aram Khachaturian, the person may feel increased strength in his body. So, anxiety, impatience, frustration, etc. that people living in the modern era feel may disappear by listening to calm, slow, dynamic or fast music, so that people may feel more comfort, rest and stability in mind. 5 In addition, a low frequency therapy device using a low frequency voltage pulse has been developed for enhancing blood circulation. The low frequency therapy device increases DC power to generate a low frequency signal around 100hz or less, and the above output is connected with conducting pads "+" and "-". The conducting pads are in direct contact with the person, so that the low 10 frequency electric pulse can stimulate the human body. The low frequency therapy device is placed at acupuncture spots of a human body or a portion where the person feels muscle pain to obtain a certain therapy effect. In the low frequency therapy device, an output level may be adjusted in 15 accordance with the control of a microcontroller that operates based on a method similar to volume level control. The above output levels can be adjusted without set levels, but a digital control that utilizes microcontroller has not yet been obtained. Since the above output level is controlled based on an analog method, it is inconvenient to use. 20 When the control and indication are performed using a microcontroller, it is possible to advantageously implement various controls, classified indications for expressing a control state and automated therapy courses which are performed in multiple stages. According to the conventional art, in an output setting unit which sets a low 25 frequency output of a microcontroller and variably controls the output, because 2 3 different resistances are formed using potential divide resistors at four output ports of a microcontroller to adjust the potential divide ratio, it is possible to control the amplitude of an input power of a low frequency output unit. The output can be set to ten different levels that are a combined ratio of the 5 potential divide resistors at four points. The above low frequency therapy device is designed to stimulate the nerves using finger pressure protrusions or conductive pads that are attached to a foot sole or a portion of the human body. Because the conventional low frequency therapy device is designed to randomly generate low frequencies 10 and stimulate the nerves of each portion of a human body, it is impossible to obtain a desired stimulation effect. When it is used for a long period of time, the user may feel discomfort, so that a desired therapy effect cannot be obtained.

The low frequency generation unit 250 outputs a low frequency electric pulse by adjusting the intensity and speed of the low frequency generation in synchronization with the high and low frequency sounds and tempo of the sampled classical music, pop 5 song, folk song, etc. Here, the low frequency electric pulse is transferred to a certain portion of a human body through a finger pressure protrusion, a conductive pad, or other low frequency transfer units that electrically stimulate the nerves of a human body. Because the constructions of the sound output unit 220, the control unit 210, 10 and the low frequency generation unit 250 are the same as the previously described constructions with reference to Figure 3, the detailed description thereof will be omitted. The operations of the music-synchronized low frequency stimulator according to the preferred embodiments of the present invention will be described. 15 First, the user turns on the low frequency stimulator 200 and selects a certain output level of the low frequency electric pulse and an output level of music on the menu displayed on the display unit 217 by using the input unit 216 of the control unit 210 and plays classical music, pop song, folk song, etc. through the sound output device 220 such as the cassette tape recorder deck 222, the CD 20 deck 224, the AM/FM tuner 226, or the MP3 memory 228 and connects a headphone with the external output unit 230. The music is managed and controlled by the sound controller 221 and is transmitted to the controller 211 of the control unit 210. The amplifier 214 amplifies the music in accordance with the control of the 25 controller 211 and outputs the music to an external output unit 240 through a
II
headphone, so the user can listen to music such as classical music, pop song, folk song, etc. The modulation and demodulation unit 213 analyzes the music in accordance with the control of the controller 211 by extracting and sampling the 5 high and low frequency sounds and tempo of the music in synchronization to synchronize the intensity and speed of the generated low frequency signal. The low frequency electric pulse is generated in accordance to the intensity and speed depending on multiple potential divide resistors that are set by user input and that control the power from the low frequency generation unit 250 in 10 synchronization with the sampled high and low frequency sounds and tempo of the music. The generated low frequency electric pulse stimulates the user's body or a certain portion of the user's body through a finger pressure protrusion, a conductive pad, or other low frequency transfer units in synchronization with the 15 high and low frequency sounds and tempo of the music. As described above, in the music-synchronized low frequency stimulator according to the present invention, because the low frequency electric pulse is generated in synchronization with classical music, pop song, folk song, etc. selected by the user as compared to the low frequencies which are randomly 20 generated by conventional art, the user can be provided with low frequency treatments while listening to music, and thereby maximizing the therapy effect. As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are not limited by any of the details 25 of the foregoing description, unless otherwise specified, but rather should be 12 construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims. 13
