An inexpensive take-home training aid for practicing human cardiopulmonary resuscitation (CPR) is contained in a non-humanoid shaped housing. When placed in a prominent location in the home, such as a child's room, the CPR training aid reminds users of the CPR sills they have learned and encourages them to practice with the training aid. The internal mechanism consists of a simulated airway, a compression mechanism, a compression feedback mechanism, a metronome, a breast plate and back plate with simulated anatomical landmarks, and / or an external landmark for identifying the proper location for placing a hand, hands, or fingers on the chest. Voice prompts on the steps of CPR and / or actual CPR performance may also be included. The chest plate and back plate are connected by one or more telescoping posts and a resistance device is between the two plates to simulate the resistance of a human chest to compression. The internal mechanism can be placed in a variety of non-humanoid containers such as a child's teddy bear or other stuffed toy. A CPR student can use the toy or other non-humanoid container to practice CPR during a CPR class and then later at home.

Herein described are at least a method and a system for assisting a musician in playing an instrument by way of using an intelligent multifunctional digital music display device (MDMDD). The multifunctional digital music display device (MDMDD) may be used to assist musicians or performers during practice sessions or performances. The various aspects of the invention provide a method of constructing an ADSR envelope for a note generated by an instrument, displaying one or more pages of music, generating a more accurate metronome beat consistent with the music being played, and alerting the musician when his instrument is out-of-tune. Further, the various aspects of the invention provide a method of statistically monitoring and reporting the performance of the musician. The system comprises a storage device capable of storing an instructional code, a processor for executing the instructional code, a microphone, and a display.

An interval timer combining the features of a practice timer, means of measuring date and metronome into a single device for the purpose of measuring, recording, and displaying practice records over a period of weeks or months. During the measuring of practice time, the device may complement the passage of time by the use of lights, sounds, or vibrations. It features a display screen that can indicate total time practiced, current chronological time and date, and a record of practice accomplished over a period of chronological time. The device may also accommodate interchangeable face plates of electronic icons for user personalization of the device. An enhanced version may include means for displaying assignment and practice information.

The invention discloses an electronic device for displaying and playing a music book. A user can be respectively in a music book display work mode, a music book play work mode and a metronome work mode through functional keys connected to functional key interfaces. The invention is applicable to displaying and playing various music books such as numeral notation, stuffs, tablatures and the like, and is an auxiliary device for music learning and teaching.

A laser or other substantially collimated light source is operatively connected to a reciprocating driver that causes a beam from the laser to sweep across a conveniently viewable surface at an adjustable frequency, thereby tracing a pattern on the surface between a plurality of beam path boundaries. The beam's direction change at a beam path boundary generally serves as a visual indication of a musical beat. The laser may be positioned and / or aimed to project the beam on any surface. The frequency of driver reciprocation (i.e., the tempo) may be adjusted to correspond to one of a range of typical musical tempos, thereby providing the functionality of a metronome but with the novel and useful additional element of a projected beat image.

The invention discloses a high-accuracy detection method for the tone color of a musical instrument. The method mainly comprises the following steps of: performing operation on a standard tone signal produced by the musical instrument according to time-domain characteristics of an audio signal to obtain a relationship between standard tone frequency in spectral characteristics and the composition of each harmonic tone component and the intensity of each harmonic tone by using a signal operation control unit, comparing the time-domain characteristics and the spectral characteristics of the musical instrument to be detected and a standard musical instrument to obtain a tone color detection result of the musical instrument, and transmitting the result to a result display unit. A user can find a corresponding improvement method by regulating or optimizing the performance of the detected musical instrument according to the detection result, and the method can be used for conveniently and quickly identifying the tone color of the musical instrument. A power supply, an audio signal input unit, a signal acquisition unit, a data storage unit, the signal operation control unit and the result display unit are involved. The method for detecting the color tone of the musical instrument is high in measurement accuracy, convenient to use, intuitive, accurate and reliable, and can be used for tone setters, tuners, metronomes and the like of various musical instruments.

To provide an electronic metronome making a display similar to the movement of a mechanical metronome or a parabolic movement, an electronic metronome of the present invention includes a timing setting portion for setting a timing for emitting a sound, a control portion that outputs pieces of tempo indication data and a tempo sound signal, which are based on a piece of data on a set tempo, respectively at timings based on a piece of sound emission timing information set by the timing setting portion, a display portion that is constructed of a plurality of light emitting elements or liquid crystal display segments and visually displays a tempo by sequentially displaying the pieces of tempo indication data outputted from the control portion, and a sound emitting portion that emits a sound through amplification of the tempo sound signal outputted from the control portion.

A system and method for generating a synchronized mix of a plurality of audiovisual tracks is provided. A new audiovisual track may be recorded simultaneously while one or more other audiovisual tracks are being played to help simulate a live jam session as closely as possible. In a “DJ Mix” mode, a user may manipulate sequencing and / or characteristics related to one or more audiovisual tracks included in a project in real-time while the project (e.g., song) is being played. A synchronized mix of a plurality of audiovisual tracks may be generated based on various attributes associated with the audiovisual tracks. For example, audiovisual tracks that are recorded along with a metronome may be synchronized based on a metronome clock rate selected by a user.

A metronome ticking the beat for performance especially with moving tempo, and having display looks like conductor's baton so that watcher can precisely predict beat timing to catch up the moving tempo. It has tapping button to record all the beat duration time data on memory. With the data on memory all the beats can be reproduced. Partial modification of beat duration time is also possible by tapping. Dedicated device uses vertically placed light emitting element array. Emitting point moves like ball thrown upward. Bound timing is beat timing. The metronome opens new way to produce music minus one or karaoke media.

The invention discloses a sound-light centering mode rhythm-showing method and apparatus in which a frame is configured, electronic circuits of a metronome or a rhythm sound corrector are designed in an inner portion, keystokes and a related segment array of LED or LCD display units which are vertically or horizontally arranged are designed in an outer portion. At a rhythm time of each rhythm / rear half-rhythm time, display light points are fulgurated one by one in an order from a centre to two ends / from thw two ends to the centre, and corresponding sound is synchronously cooperated, thereby forming an intuitionistic effect of simulating clapping hands to show the rhythm. The invention can be directly used in a metronome or a rhythm sound corrector which show the rhythm vertically and horizontally, and is better for music study of children.
