Abstract: A portable device case can be engage various removably attachable accessories. The case is sized and shaped to at least partially enclose the mobile device and includes an opening sized and shaped to receive at least a portion of a casing of an accessory, a top flange sized and shaped to removably engage with a top flange of the casing of the accessory, and a bottom flange sized and shaped to removably engage with a bottom flange of the casing of the accessory. Various accessories and removable attachments can be used with the case.

Abstract: A speaker and conference call module and mobile device case combination allows a mobile device, such as a smartphone, to be retained by the mobile device case. The speaker and conference call module is configured to wirelessly connect to the mobile device to permit audio from the mobile device to be played thereupon. The speaker and conference call module further includes a microphone to permit audio pick-up by the module and deliver that audio signal to the mobile device, permitting two-way conference call features. The speaker and conference call module can produce sound via one or more exciter voice coils internally attached to the front surface thereof, where the front surface may be a material suitable for sound generation via an exciter, such as a carbon fiber material. The speaker and conference call module can be removed from and reattached to the mobile device case for convenient portability.

Abstract: A game surface, such as a top surface of a cornhole game, can be configured to produce a sound by using a sound system mounted on an underside of the cornhole platform. The sound system can use one or more exciters to produce sound through the top surface of each of the two cornhole platforms used for game play. In some embodiments, a communication protocol may link the two sound systems, in each of the two cornhole platforms, so that each platform generates the same sound from a single source. The sound system may be easily retro-fitted to existing cornhole game platforms or may be formed during manufacture thereof.
