摘要： A musical device includes a body and at least one actuator mechanism. In one embodiment, the musical device can generate an audio output in response to activation by a user of the actuator mechanism. In one embodiment, the musical device body includes multiple parts that can be moved relative to each other. The parts enable the musical device to resemble one or more musical instruments.

摘要： A speaker edge is made of a thermosetting composition consisting of a polyurethane prepolymer and an inactivated solid polyamine as a latent hardener. A gas is dispersed in the thermosetting composition, prior to feed into a mold, so that it can foam and solidify to give the speaker edge. In a method of making the speaker edge, the composition will be injected into a female mold segment heated below the critical thermosetting temperature, foaming the composition. Then placed in the female segment is a male segment heated above the critical temperature, causing the ingredients to react with each other to solidify in the mold. An apparatus for making the speaker edge from the composition has: a device for intake of a gas, another device for injecting the composition into the gas, another device for mechanically dispersing the gas throughout the composition, still another device for injection of this gas-containing composition into a female mold segment, a further device for placing a male segment in the female segment, and a still further device for solidifying the composition, while foaming it.

摘要： Portable and foldable modular electronic keyboard which includes a keyboard having a plurality of white and black keys capable of reproducing the notes of a piano through an individual headphone by using associated electronics. The foldable keyboard is formed from a plurality of modules, each module having a plurality of white and black keys, and each module being joined to another module by a flexible membrane. When the modules are folded together, the keyboard has the volume of a book. When the modules are unfolded, the keyboard presents a genuine piano keyboard with seven octaves. The white keys and the black keys forming each module have a low thickness.
