To enable the production of good musical tones in response to the user's playing input. [Solution] The CPU of the electronic instrument determines the first pitch that is closest to the pitch corresponding to the pressed key from among the chord tones corresponding to the chord information at the time any key is pressed by the user in the currently playing song. If the first pitch is not being played, the CPU causes the sound-producing part to play at the first pitch. If the first pitch is being played, the CPU causes the sound-producing part to play at the second pitch, which is in the same direction as the first pitch included in the chord tones, relative to the direction of the pitch corresponding to the current key press relative to the pitch corresponding to the previous key press.

This invention relates to the field of temperature compensation technology and discloses a temperature compensation and heat dissipation device for electronic instruments. The device includes a second fixed plate, a first heat-absorbing plate fixedly connected to one side of the top of the second fixed plate, a second heat-absorbing plate fixedly connected to one side of the first heat-absorbing plate, a fifth fixed block slidably connected to one side of the second heat-absorbing plate, an adjustment mechanism externally provided on the fifth fixed block, a second heat-conducting pipe movably connected to one side of the second heat-absorbing plate, and a fixed connection between the second heat-conducting pipe and the fifth fixed block. The second fixed block is fixedly connected to the top of the second fixed plate, and a cooling mechanism is externally provided on the second fixed block. This technical solution solves the problem in the prior art where electronic instruments easily generate a lot of heat, requiring cooling, but the heat-conducting pipe is generally fixed and difficult to adjust according to the size of different electronic instruments.

This utility model discloses a synchronous clock detection carrying case, specifically relating to the technical field of peripheral equipment for precision electronic instruments. The case includes a rotating cover rotatably connected to the inner wall of the top back of the case. A synchronous clock detector is installed inside the case. A sealing assembly is provided inside the case, and a support assembly is provided at the bottom of the case. The sealing assembly includes two fixing rods, both of which are fixedly connected to the inner wall of the case on their front and back sides. This utility model, by setting up a sealing assembly—specifically, a square frame rotating to push a sealing plate downwards—allows the outer surface of the bottom of the square frame on the inner wall of the sealing plate to engage, sealing the gap between the rotating cover and the carrying case. This not only prevents dust accumulation on the surface of electronic components from hindering heat dissipation and causing oxidation and corrosion of metal contacts, but also ensures that the performance of precision components remains unaffected by reduced dust and moisture interference.

This application discloses a method for early warning of abnormal tire trends in vehicle electronic instruments, comprising: collecting tire state data within a preset time period, including tire pressure, temperature, and wheel speed; calculating the slope of the tire state change trend within the preset time period based on the tire state data; using the tire state data, the slope of the state change trend, and the vehicle operating conditions, outputting the tire abnormality type and a dynamic warning value; and outputting a corresponding warning command according to the magnitude of the warning value and a preset warning level value. This invention, by calculating the slope of the state change trend, achieves a shift from post-event detection to early warning, solving the problem of delayed warning response caused by relying on static thresholds, and significantly improving the timeliness, accuracy, and driving safety of warnings.

The presence of saxophonists furthering their musical horizons by playing keyboard instruments inspires the invention of a novel device to connect a light-weight keyboard or MIDI grid controller to a saxophone to facilitate the convenient and rapid switching between playing either instrument. Battery power and Bluetooth technology combine with innovations in plastics technology to facilitate the creation of strong, lightweight structures to facilitate such a device. With the addition of looping software on a laptop computer, a saxophonist so equipped can create music to accompany themselves, obviating the need for other musicians to function as a musical ensemble. This innovation may be the harbinger for other musicians on other single note instruments—trumpet, trombone, violin, etc. to join this trend using either instrument-attached, strap-on or wearable keyboards. This could blend the boundaries between acoustic and electronic instruments, and increase the enjoyment and musical enrichment of musicians and audiences alike.
