    Abstract: An abnormal sound detection device for detecting a peripheral interface device includes a vibration simulation mechanism, a movable-type audio collecting device and a controlling and analyzing device. The vibration simulation mechanism includes a mechanism body. The peripheral interface device is accommodated within the mechanism body. The vibration simulation mechanism generates a vibration force. The peripheral interface device generates a vibration sound wave in response to the vibration force. The movable-type audio collecting device collects the vibration sound wave. The audio collecting device generates a vibration audio signal in response to the vibration sound wave. The controlling and analyzing device generates an abnormal sound detection signal to control the vibration simulation mechanism to generate the vibration force. The controlling and analyzing device detects and identifies whether there is an abnormal sound phenomenon in the vibration audio signal.

    Abstract: A control device with a capacitive-type visual key structure is provided. The control device includes a covering member and a transparent keycap. The covering member includes an accommodation space. The transparent keycap is accommodated within the accommodation space. An elastic element, a first electrode, a key circuit board assembly with a second electrode and a display panel are accommodated within the accommodation space. When the transparent keycap is pressed down, the elastic element is correspondingly moved, and a spatial distance between the first electrode and the second electrode is changed. Consequently, a capacitance change value is formed. According to the capacitance change value, the control device judges whether the transparent keycap is pressed down and triggered.

    Abstract: An image capturing device includes a casing, a camera assembly, an adjustment element, a first stopping structure and a second stopping structure. The camera assembly is disposed within the casing. A portion of the camera assembly is exposed outside the casing. The adjustment element is connected with the camera assembly, and rotatable relative to the casing. As the adjustment element is rotated, the camera assembly is correspondingly rotated. The adjustment element includes a contacting structure. The first stopping structure and the second stopping structure are arranged between the casing and the adjustment element and located at different positions. When the camera assembly is switched to a horizontal photographing mode, the contacting structure is positioned at the first stopping structure. When the camera assembly is switched to a vertical photographing mode, the contacting structure is positioned at the second stopping structure.

    Abstract: A close-type speaker leak test system includes a first chamber, a second chamber, a third chamber, a fourth chamber, a vacuum generator, and a differential pressure gauge. Firstly, a negative pressure value of the first chamber and the second chamber is generated by the vacuum generator. A standard close-type speaker is placed within the third chamber, and the first chamber and the third chamber are in communication with each other. An under-test close-type speaker is placed within a fourth chamber, and the second chamber and the fourth chamber are in communication with each other. A pressure difference value between the third chamber and the fourth chamber is measured by the differential pressure gauge. If the pressure difference value is larger than a predetermined value, the under-test close-type speaker has the leak. Consequently, the misjudgment is reduced, and the testing efficiency is enhanced.

    Abstract: A headphone device includes a sound outputting part and a sensor. The sound outputting part includes a case, a main board, a driving unit, a baffle plate and an ear pad. The sensor is installed on the baffle plate, uncovered by the ear pad and connected with the main board. If the human ear is sensed by the sensor, the main board judges that the headphone device is worn by the user. If the human ear is not sensed by the sensor, the main board judges that the headphone device is not worn by the user. According to the result of judging whether the headphone device is worn by the user, the playback of the audio content of an electronic device connected with the headphone device is correspondingly controlled.

    Abstract: An audio playback system includes a handheld device and a digital stereo set. By the handheld device, a control message is converted into a pulse signal. Moreover, the on/off states of a visible light emitting element are controlled according to first pulse signal, so that a visible light signal is generated. After the visible light signal is received by an optical sensor of the digital stereo set, the visible light signal is restored to the control message. After the control message is received by the digital stereo set, the digital stereo set performs a corresponding control action.
