Abstract: A camera device connection structure includes a circuit board, a lens assembly and a case assembly. The lens assembly is disposed on upper side of the circuit board and has a first mating section and a second mating section respectively disposed on two opposite sides of the lens assembly. The case assembly has a first case body and a second case body. The first and second case bodies are disposed on the upper side of the circuit board and respectively positioned on two sides of the lens assembly. The first and second case bodies respectively have a first connection section and a second connection section corresponding to the lens assembly. The first and second connection sections are respectively connected with the first and second mating sections of the lens assembly, whereby the structural strength of the camera device can be still enhanced in precondition that the camera device is thinned.

Abstract: A camera module protection structure includes a circuit board, a case and a camera device. The case is disposed on the circuit board. At least one side of the case is formed with a securing section. The case is formed with a receiving space in a position corresponding to the securing section. The camera device is correspondingly disposed in the receiving space. According to the structural design of the camera module protection structure, the securing section of the case is able to enhance the structural strength of the entire camera module and greatly lower the damage ratio of the camera module and prevent the circuit board from being easily broken off or damaged in assembling process of the camera module.

Abstract: An audio jack for receiving an audio plug includes a connection hole with a position detection portion and a first audio channel contact portion therein. When the audio plug is inserted into the connection hole to the linking position, a first audio channel connection portion of the audio plug contacts the position detection portion and the first audio channel contact portion. The position detection portion and the first audio channel contact portion respectively have a first distance and a second distance to an opening of the connection hole, wherein the second distance is smaller than the first distance.

Abstract: An electronic device includes an audio jack, a power supply unit, a determining circuit, and an executing circuit. The audio jack may be arranged for transmitting an audio input signal, and the electronic device may be configured to connect with an audio accessory via the audio jack. When the audio accessory may be connected to the electronic device, the power supply unit provides a first voltage to the audio jack and a second voltage. The determining circuit determines whether to trigger an interrupt request according to the second voltage and a third voltage, wherein the third voltage may be coupled to the audio jack and may be generated according to the first voltage. The executing circuit may be coupled to the determining circuit, for determining whether to execute a corresponding function according to the third voltage when the interrupt request may be received.

Abstract: A heat dissipating tube with copper powders comprises a metal tube; an inner wall of the metal tube having at least one non-flat portion; and a plurality of copper powders adhered on the inner wall of the metal tube. There are a plurality of non-flat portions which are distributed along a periphery of a cross section of the metal tube. A cross section of the non-flat portion has a shape selected from one of trapezoids, rectangular shapes, semi-round shapes, sector shapes, sawtooth shapes, triangular shapes, or other irregular shape. The non-flat portion may be selected from one of at least one trench, at least one protrusion and at least one groove.
