Abstract: A musical instrument stand clamp, which to be fixed to a stand, comprises a fixed part, a movable part, and a screwing-lock part. The movable part is pivotally coupled to a pivotal point of the fixed part. The fixed part includes a locked section and a clamping section respectively at two sides of the pivotal point. The movable part includes an outer curved surface near the locked section and a movable member far away from the locked section. The screwing-lock part is screwed through the locked section to push the outer curved surface of the movable part and rotate the movable part with respect to the fixed part so as to move the movable member toward a clamping member of the locked section, whereby the clamp is fixed to the stand. Thus, the clamp can be fast assembled or disassembled merely via rotating the screwing-lock part.

Abstract: The present invention relates to a bidirectional voice transmission system and a method thereof, wherein the system timing of the system is divided into three time slots for carrying a control signal, a broadcast voice signal and a mobile device voice signal. The bidirectional voice transmission system is able to carry out the signal transmission by way of frequency frogging, so as to effectively avoid the signal interference from occurring between any two different signal transmitting and receiving devices. Besides, all of the mobile devices can be added into the bidirectional voice transmission system by way of dynamic building, without using any specific communication interface. The most important is that, the number of node routers can be expanded to about 65,000 in order to apply the bidirectional voice transmission system in a huge range network communication or a wild rescue field.

Abstract: A game recording apparatus includes a video processing module, a video buffering module, an information converting module, a subtitle buffering module, and a video integrating module. The video processing module is coupled between a game console and video buffering module. The information converting module is coupled between a game controller and subtitle buffering module. The video processing module receives a video signal from game console and codes it, and coded video signal is stored in video buffering module. The information converting module receives an operation information from game controller and converts operation information into a subtitle information and saves it into subtitle buffering module. The video integrating module integrates coded video signal and subtitle information into a game video information with a specific video format. Therefore, requirements of time constraint and computing power can be reduced and operation load and cost of game recording apparatus can be lowered.

Abstract: A pedal beating apparatus for musical instruments comprises a pedal beating holder, an elevation adjustment tray and a clamp beam. The elevation adjustment tray is movable against the pedal beating holder and has an elevation difference curved surface. The pedal beating holder has a fulcrum member. The clamp beam hinged on the fulcrum member has a clamp end and a leaning end at two ends. A compression spring is interposed between the clamp beam and pedal beating holder and located between the clamp end and fulcrum member to allow the leaning end to move downward to contact the elevation difference curved surface. By moving the elevation adjustment tray, position of the leaning end contacting the elevation difference curved surface is adjusted to further drive the clamp end to move. Thus distance between the clamp end and clamp boss can be changed to rapidly clamp drum hoops with varying thicknesses.

Abstract: A portable cajon hitting assembly comprises a foot pedal, a wire tube, an upright plank, a bracing bar, a hitter and a holding rack. The wire tube is threaded by a drawing wire having a start end and a distal end. The upright plank has a turnable axle. The foot pedal is connected to the start end of the drawing wire through a chain. The bracing bar has two ends fastened respectively to the axle and the distal end of the drawing wire. The hitter is fastened to the axle. The holding rack clamps and holds a cajon. Thus, through relative positions of the bracing bar and drawing wire and a lever action, the drawing wire can draw the axle to turn at an optimal angle, and also increase instantaneous torsional force to enhance smoothness during treading of the foot pedal. Moreover, the invention also can be stored easily.
