Abstract: A retractable ear bud module. The ear bud module is has a housing for holding an ear bud cable, an ear bud cable moveably mounted in the housing, the ear bud cable having a free end with at least one ear bud and a fixed end. A circuit board including a wireless receiver mounts in the housing for communicating with the electronic device. The wireless receiver electronically connects with the ear bud cable to transfer audio signals from the electronic device to the ear bud. A retraction mechanism mounts in the housing to retract and dispense the ear bud cable. The retraction mechanism includes a rotatable spool mounted in the housing, a spring recessed centrally within the spool, and an annular retainer circumscribing the spool to align the ear bud cable on the spool.

Abstract: A retractable ear bud module has a housing with an ear bud cable retractable mounted in the housing. The ear bud cable has at least one ear bud and a microphone, and a fixed end attached to a circuit board including a wireless receiver mounted. The wireless receiver electronically connects with the ear bud cable to transfer audio signals from the electronic device to the ear bud and from the microphone to the wireless receiver. A spool, mounts in the housing to retract and dispense the ear bud cable. In order to avoid entanglement of the microphone in the spool and housing, the microphone is integrated with the ear bud in one embodiment, is collocated with the ear bud in an alternate embodiment, and is distanced by no more than two inches from the ear bud in another embodiment.

Abstract: A device removeably attachable to a case for an electronic device for delivering sound includes a housing having a speaker means and a printed circuit board assembly mounted in the housing. The printed circuit board assembly is in electronic communication with the speaker means. The printed circuit board assembly includes a wireless communication module having an antenna to enable wireless communication with the electronic device. The printed circuit board and having a curved shape to partially circumscribe the speaker means to enable the speaker means and the circuit board to lie co-planar. In one embodiment, the speaker means is a retractable ear bud device. In another embodiment, the speaker assembly is a speaker with an annular periphery and a body with a truncated conical shape, whereby the printer circuit board lies co-planar with a portion of the body of the speaker.
