Abstract: An earphone integrated with a microphone includes a housing, a speaker, a microphone (audio-recording device), and a supporting member. The housing has an audio-output hole formed thereon a receiving space formed therein. The speaker and the microphone are arranged in the receiving space. The supporting member is arranged in the housing. One end of the microphone is mounted on the supporting member for suspending the microphone in the receiving space. A buffering space is formed around the microphone. Thus, the earphone can achieve anti-noise effect in providing improved communication quality.

Abstract: The instant disclosure relates to a loudspeaker, which includes a ferrite core, a voice coil, and a movable membrane. The voice coil is wound around the core and cooperatively defining an exciting device. The movable membrane is disposed in close proximity to the exciting device with a gap formed thereinbetween. The loudspeaker constructed without permanent magnets takes up less space and is more cost effective. Thus, the loudspeaker has a broader application range.

Abstract: A portable information product capable of projecting to a surface, such as a cellular phone, has a data processing device and a built-in projection device. The data processing device has a main circuit module for processing data thereof and forming an output signal from the data. The built-in projection device is disposed in the data processing device and electrically connects to the main circuit module. The projection device has a light source and a projector, and the projection device has a fixed focal length. The light source generates a light. The light and the output signal are transmitted to the projector to form an image, when the distance between the projection device and the surface is approximately equal to the fixed focal length of the projection device, and the projector projects the image outside the data processing device to project on the surface.

Abstract: An earphone device integrated with a microphone has a main body, a microphone unit and a speaker unit. The microphone unit has a sound-absorbing film and a circuit unit, the sound-absorbing film being a hollow column and being connected to the main body through a rear end thereof, and the circuit unit being fixed on the main body and electrically connected to the sound-absorbing film. The speaker unit is mounted inside the sound-absorbing film of the microphone unit such that the microphone unit is located peripheral to the speaker unit. A microphone and an earphone can thus be integrated together as a whole so as to form an earphone device that can be used conveniently.

Abstract: A Bluetooth earpiece with two-way audio transmissions adopts a base body combined with a Bluetooth earphone containing a signal transmitting end. An electrically connected amplifying unit, loudspeaker unit and audio signal capture unit are installed in the base body. The amplifying unit electrically connects to signal transmitting end of the Bluetooth earphone while the Bluetooth earphone is inserted in the base body. The Bluetooth earphone is capable of receiving audio information from a remote end and sending the information to the loudspeaker unit of the Bluetooth earpiece through an audio transmission switching unit in the Bluetooth earphone to produce sounds. In the meantime, users can receive the sounds by the audio signal capture unit of the Bluetooth earpiece, and the captured audio information is sent to the Bluetooth earphone through the amplifying unit to complete the two-way audio transmission.
