发明名称 SPEAKER APPARATUS FOR HANDHELD ELECTRONIC DEVICE
摘要 An improved speaker apparatus for use in association with a handheld electronic device includes an actuator, an audio transducer, and a connection that is connectable with the handheld electronic device. The speaker apparatus additionally includes a power system that is connectable with a power source. The connection enables the communication of audio signals between the speaker apparatus and the handheld electronic device, and also provides power to operate and/or charge the handheld electronic device. When the speaker apparatus is connected with the handheld electronic device, the audio transducer serves as both a loudspeaker and a microphone for use in, for example, telephone communications using a wireless communication apparatus of the handheld electronic device.
