Abstract:
A leak test system and a leak test method are provided for testing whether a semi-finished product of a speaker has a leak. The semi-finished product of the speaker includes a case. An interface is installed on a surface of the case. The leak test system includes a covering element, a vacuum generator, and a pressure gauge. The covering element is attached on the surface of the case, so that the interface of the semi-finished product of the speaker is covered by the covering element. A negative pressure value of the covering element is generated by the vacuum generator. If the equilibrium pressure value is lower than a default negative pressure value, the leak test system judges that the semi-finished product of the speaker has the leak. Consequently, the testing efficiency is enhanced.
Abstract:
A stereo device testing method includes the following steps. Firstly, a stereo device is fixed, and a gas is continuously inputted into an inner space of the stereo device. After a predetermined time period, an internal pressure value of the inner space of the stereo device is detected. By judging whether the internal pressure value is higher than or equal to a default pressure value, the tester may determine whether the stereo device is qualified or not. After the stereo device is tested, the manufacturer of the stereo device may repair the gas leakage position. Since the influence of the gas leakage condition on the resonant effect is minimized, the sound quality of the stereo device is enhanced.
Abstract:
A desktop three-dimensional image scanner is provided for producing a humanoid vision-based three-dimensional image. The desktop three-dimensional image scanner includes an image pickup device and a position-limiting mechanism. The position-limiting mechanism is used for fixing the image pickup device at a first shooting position or a second shooting position. A spacing distance between the first shooting position and the second shooting position is in a range between 6 and 70 millimeters. An included angle between an optical axis of the image pickup device at the first shooting position and the optical axis of the image pickup device at the second shooting position is in a range between 1 and 30 degrees.
Abstract:
An image capture device includes a casing, a camera module, a rotatable member, and a pan-tilt module. The casing includes front and rear casings. The camera module is disposed in the casing. A portion of the camera module is through an opening region of the front casing. The camera module includes a lens module bracket and a lens module disposed therein. The rotatable member is fixed on the lens module bracket. The rotatable member is configured to rotate the camera module when the rotatable member is rotated relative to the casing, so that the lens module is switched between horizontal and vertical shooting modes. The pan-tilt module includes a motor bracket, first and second motors. The first motor is connected between one end of the motor bracket and a sidewall of the casing. The second motor is connected to another end of the motor bracket.
Abstract:
A digital photographing device is provided. The digital photographing device can be operated in at least two manual focus modes to provide at least two different common focus lengths. The user can select a suitable manual focus mode from the at least two manual focus modes. When the user faces the digital photographing device to take a selfie or create a live stream, the user can realize the current focus mode of the digital photographing device in real time according to the indication of the focus mode indication module.
Abstract:
A key structure includes a casing, a covering member, a pressing element, a triggering post, a switch element. The casing has an opening. The opening is covered by the covering member. The pressing element is disposed within the opening and connected with the covering member. The pressing element includes a middle part and an extension part. The triggering post is installed on the middle part of the pressing element. The triggering post is extended in the direction toward the inner position of the casing. When an external force is applied to the middle part of the pressing element, the triggering post is moved toward the switch element to push the switch element. When the external force is applied to the extension part of the pressing element, the triggering post is correspondingly moved with the pressing element in an inclined manner to push the switch element.

Abstract:
An input device assembly with a support pad is provided. The input device assembly includes the support pad and an input device. The support pad includes a first main body and a first magnetic attraction element. The first main body has a first bottom surface and a first curvy surface. The input device includes a second main body and at least one second magnetic attraction element. The second main body has a second bottom surface and a second curvy surface. The first curvy surface of the support pad is contactable with one of plural portions of the second curvy surface of the input device. The first magnetic attraction element and one of the at least one second magnetic attraction element are magnetically attracted by each other. Consequently, the support pad is in close contact with the input device.
Abstract:
An input device includes a casing, a base member, a ball member, a control ring and a gravity wheel. The casing includes an upper cover and a lower cover. The upper cover has an opening. The ball member is installed on the base member. The ball member is partially exposed outside the opening. The control ring is arranged around the base member. The control ring is partially exposed outside the opening. The control ring is freely rotatable around the base member. The control ring includes a first inclined part, a rack structure, and a lateral wall. The lateral wall is connected with the first inclined part and the rack structure. The gravity wheel is engaged with the rack structure. Consequently, the rotation of the control ring is suppressed by the gravity wheel.
Abstract:
A control device is connected with a microphone and a display device. The control device can be used to implement a microphone gain setting process. The control device includes an adjustment knob. When the adjustment knob of the control device is pressed down, the control device starts to implement the microphone gain setting process. At the same time, a message is shown on the display device to prompt that the control device starts to implement the microphone gain setting process and prompt the user to emit a sound to the microphone for a time period. Consequently, the sound is amplified by a signal gain amplifier of the control device. Then, a message is shown on the display device to prompt the user that the microphone gain setting process is completed.
