A handheld electronic device includes a first speaker, a second speaker, and an audio controller. The audio controller includes a signal receiving unit, a frequency crossover unit, a harmonic-wave generating unit, a low frequency enhancement unit, and a signal synthesis unit. The signal receiving unit receives an original sound signal and generates a first channel signal and a second channel signal according to the original sound signal. The frequency crossover unit sets a preset frequency crossover point to filter the first channel signal to generate a low frequency signal. The harmonic-wave generating unit generates harmonic waves according to the low frequency signal. The low frequency enhancement unit generates an enhancing low-frequency signal according to the harmonic waves. The signal synthesis unit generates a first channel enhanced signal according to the enhancing low-frequency signal and drives the first speaker.

Handheld electronic device with multiple speakers

An audio processing method includes the following steps: receiving audio information; capturing a square wave signal, a white signal, and a speech signal of the audio information; calculating a loudness value of the audio information; calculating a first sound quality value and a second sound quality value of the audio information by using the square wave signal, the white signal, and the speech signal of the audio information; calculating a sound quality level of the audio information by using a first calculation formula, the first calculation formula being the loudness value*[1+(B*the first sound quality value+C*the second sound quality value)], where B and C are respectively values greater than 0 and less than 0.1; and displaying a value of the sound quality level of the audio information.

Audio processing method and audio processing device

A wireless charging receiving device for receiving power from a power transmitting device of wireless charging including a body having an accommodation space and a slot, an induction coil and an electromagnetic absorption member in the accommodation space, and a power storage module is provided. At least a portion of the body has a metal shell corresponded to the accommodation space. The slot disposed in the metal shell connects the accommodation space and an exterior edge of the metal shell. The induction coil is insulatedly abutted against the metal shell and electrically connected with the power storage module. The power transmitting device magnetically resonates with the metal shell through generating an electromagnetic field. The metal shell generates an induced current and an electromagnetic field along the slot, and power converted from the energy of the electromagnetic field is transferred and stored in the power storage module.

Wireless charging receiving device

An electronic device including a power switch, a switch unit, a power supply unit and a control unit is provided. Two power ends of the power switch are connected in parallel with two connecting terminals of the switch unit. The power supply unit generates a system voltage by a power come from the power switch or the switch unit. When the two power ends of the power switch are conducted for a predetermined time, the power is provided to the power supply unit and the electronic device starts up. Furthermore, the control unit controls the switch unit to conduct the two connecting terminals, so that the power is still provided to the power supply unit through the switch unit after the two power ends are disconnected. When the electronic device is shut down, the control unit controls the switch unit to disconnect the two connecting terminals.

Electronic device having complete power-saving mechanism

A chip antenna has a dielectric material layer, a first meandered strip, a second meandered strip and several bended strips. The first meandered strip is meandered in one direction and disposed on the dielectric material layer. The second meandered strip is meandered in another direction and disposed on the dielectric material layer. The first meandered strip is connected to the second meandered strip. The bended strips are connected to the turns of the meandered strips.

Chip antenna

A chip antenna apparatus for receiving global positioning system signals, includes a L-shaped ground area and an omni-directional chip antenna. The L-shaped ground area is disposed on a circuit board. The omni-directional chip antenna is disposed in a gap of the L-shaped ground area on the circuit board and electrically connected to the L-shaped ground area.

Chip antenna apparatus for receiving global positioning system signals

A connection apparatus for a chip antenna includes a connection base and at least one chip slot. The connection base is disposed on a circuit board and connects to the electronic components of the circuit board via a connection wire. The chip slot is disposed on the connection base for inserting the chip antenna. Thus, the chip antenna is connected to the electronic components of the circuit board via the connection wire.
