Abstract:
The present embodiments provide dual sided ear cup systems () operable with devices, such as a communication device (). The dual sided ear cup system includes a transducer () that generates acoustical signals from both a front side () and a back side (). The system preferably further includes a front side resonant frequency cavity () establishing a first resonant frequency, and a back side resonant frequency cavity () acoustically matched with the front side resonant frequency cavity. Some embodiments provide wireless communication devices () having wireless communication circuitry to receive wireless communication, a front side ear cup () and a back side ear cup () for emitting substantially the same acoustical signals corresponding to received wireless communication. The wireless device can include a display portion () having the ear cups, a keypad portion (), and a swivel connection () between the display and keypad portions.
