Provided is a guitar case that can include a body for placement of a guitar; a translucent or transparent window where a portion of the guitar is visible from outside of the case; and a speaker; wherein the guitar placed inside of the case is configured to play over the speaker with a wired or wireless connection. The guitar case can further include a panel or a screen. The screen can be a touch-screen. The panel can be configured to move to allow access to electronics inside of the case. The panel can pivot out. The guitar case can further include a door, the door having the window. The guitar case can further include a camera or a microphone. The case can be configured so that a guitar is placed at an angle of less than vertical.

Different aspects of the invention implement a sensor module that can be configured as a keyboard module or as a pedal module, allowing to connect a plurality of keyboard and pedal modules to assemble a configuration to the user’s liking, such as, for example, the usual configuration of an 87-key piano together with two pedals. The sensor module transmits information about detected key or pedal strokes to a computer application for playback, either aural or visual. At the same time, the sensor module allows, both in the keyboard module and pedal module configuration, to transmit the feeling of playing a real piano.

An expandable carrying case comprises first and second compartments. The first compartment includes a plurality of first walls forming a first space therebetween. A first opening is positioned on one of the plurality of first walls. The first opening is configured to be opened for access to the first space, and also configured to be closed to enclose the first space. The second compartment is coupled to the first compartment and configured to be stored within the first compartment to a stored state, and also configured to extend from the first compartment to an extended state. The second compartment includes a plurality of second walls forming a second space therebetween. A second opening is positioned on one of the plurality of second walls. The second opening is configured to be opened for access to the second space, and also configured to be closed.

A musical instrument carrying case having a receptacle and a lid is disclosed herein. The carrying case has a hinge that allows the lid to rotate around behind the receptacle to create an instrument stand. The hinge has at least four plates and three axles, including a free axle that permits the hinge to collapse together, resulting in a shortened distance between the lid and receptacle when in an open position.

The case for a string instrument and a bow can comprise a base shell that defines a first compartment that is configured to receive the string instrument. The first compartment can have an inner surface that is complementary to the shape of the string instrument and is configured to restrict movement of the string instrument along the longitudinal axis and the transverse axis. The base shell can further define a second compartment that is configured to receive the bow. The second compartment can have an inner surface that is complementary to the shape of the bow and is configured to restrict movement of the bow along the longitudinal axis and the transverse axis. A cover can be pivotably coupled to the base shell. In a closed position, the cover and the base shell can cooperate to fully enclose the string instrument and the bow within the case.

A protective case for large objects including a lock housing formed from a first section and a second section, both of the sections including at least one external subsection and at least one internal subsection configured to telescope inside the external subsection; and an extension lock comprising a lock housing and a compression lock, the lock housing including a screw-threaded channel, and the compression comprising at least one screw-threaded shaft with a compressive component on the interior end and a lock handle on the exterior end, the screw-threaded shaft configured to matingly engage with the screw-threaded channel of the lock housing; the compression lock configured to descend in the lock housing and compressingly lock the internal subsection in an extended position upon locking rotation of the compression lock; and the compression lock configure to ascend in the lock housing upon unlocking rotation of the cam latch.

A carrying device with a built-in security system including a security unit 10 having components housed in an integral unit, where the components include a camera 1 with a light sensor 2; with a shatter proof clear cover 3 over the camera lens 16; a speed sensor 4; a distance sensor 9; a GPS tracker 8; a transponder 7 for sending and accepting digital data; a microcontroller 15, and a rechargeable power supply 5 in electrical communication with the microcontroller 15, the camera 1, the speed sensor 4, the distance sensor 9, the GPS tracker 8 and the transponder 7; to monitor the location and contents of the carrying device and to provide real time feedback to the user.

An apparatus for covering a musical instrument such as a guitar. The system comprises a back section and a front section with each of the back and front sections being affixed along a lateral edge to a side section. The cover is formed with an interior area into which the musical instrument is inserted. The musical instrument is protected from damage in the event the instrument is mishandled, dropped or knocked into another object. Cut-outs in the sections provide access to the components of the instrument for a musician to access such components while playing the instrument with the cover system in place.
