Abstract: A circuit of light-emitting elements connected between two power terminals is disclosed in the present disclosure. The circuit of light-emitting elements includes a smooth conducting line, multiple light-emitting elements, and a zigzag conducting line. The smooth conducting line is connected to one of the power terminals. One terminal of each light-emitting element is electrically connected at a different position of the smooth conducting line. The zigzag conducting line is connected to the other of the power terminals, and the other terminal of each light-emitting element is electrically connected at a different position of the zigzag conducting line. Each shortest path, starting from one of the power terminals, passing through any the light-emitting element along the smooth conducting line, and ending at the other of the power terminals along the zigzag conducting line, has substantially a same resistance value.

Abstract: An audio playback method used in an audio playback device is provided. The audio playback method includes steps outlined below. An audio playback command is received by a processing unit through a network communication unit. A total sound channel number of the audio playback device is determined by the processing unit. A piece of audio data having a specific sound channel number is retrieved by the processing unit through the network communication unit from internet, wherein the specific sound channel number is equal to or larger than the total sound channel number. Audio playback modules are controlled to play an audio by the processing unit according to the audio data.

Abstract: A balanced push-pull loudspeaker device includes a loudspeaker box, a first loudspeaker component, a second loudspeaker component and an audio processing unit. The audio processing unit generates a bass audio signal according to low frequency parts of a first audio channel signal and of a second audio channel signal, mixes the bass audio signal and a high frequency part of the first audio channel signal, outputs a mixture of the bass audio signal and the high frequency part of the first audio channel signal to the first loudspeaker component, inverts the bass audio signal, mixes the inverted bass audio signal and a high frequency part of the second audio channel signal, and outputs a mixture of the inverted bass audio signal and the high frequency part of the second audio channel signal to the second loudspeaker component. This disclosure also provides a control method applied to the above loudspeaker device.

Abstract: An audio output device including a casing, a first speaker component, a second speaker component and a sound-guiding board, and a video/audio output device using the same are disclosed. The first speaker component is a circular speaker, and is disposed at the casing. The first speaker component faces towards a first direction. The second speaker component is disposed at the casing, and faces towards a second direction which is different from the first direction. The sound-guiding board is a square plate body, located above the first speaker component, and is separated at a predetermined distance from the first speaker component.

Abstract: A system, an audio output device, and a method for automatically adjusting a firing direction of an upward firing speaker are disclosed. The system includes the audio output device and an audio receiver. The audio output device includes the upward firing speaker. During testing, the device controls the speaker to output a test audio signal at each of multiple testing angles of elevation. The audio receiver within a receiving area receives the test audio signal and generates a received audio waveform for creating reception information. The audio output device selects one testing angle as a preset angle of elevation according to the reception information. At playing, the audio output device is controlled by a mode selection signal and chooses a correction value from a mode lookup table to adjust the preset angle. The speaker is controlled to output an audio signal at the adjusted preset angle.
