Abstract: A speaker structure includes a main body, a circuit board and a magnetic component. The main body has a receiving section and a recess formed on an outer circumference of the receiving section. A center of the main body is formed with a hole in communication with the receiving section. The circuit board has a board body and an outer frame body inlaid in the recess of the main body. The magnetic component is received in the hole. A voice coil collar is disposed around the magnetic component. Multiple windings are wound around a surface of the voice coil collar. Two ends of the windings are attached to the circuit board. According to the above arrangement, the volume of the speaker structure is greatly reduced and the manufacturing cost of the speaker structure is lowered.

Abstract: A fan vibration absorption structure applied to a fan set having a first side and a second side respectively having multiple first and second fixing holes. The fan vibration absorption structure includes: a housing for receiving the fan set; a first frame body having multiple first through holes on the first side without contacting therewith, a first gap being defined between the first frame body and the first side, the first frame body having multiple first locating sections each having a first perforation, a second gap being defined between the first locating section and the housing; multiple first assembling member each having a first engagement section clamped between the first frame body and the first side to form the first gap; and multiple second assembling members each having a second engagement section clamped between the first locating section and the housing to form the second gap.

Abstract: A fan motor control device includes a zero-crossing detection unit, a phase control unit, an operation processing unit, a first rectifier element and a second rectifier element. The zero-crossing unit generates a synchronization reference signal to the phase control unit, which in turn generates a phase control signal to the operation processing unit. According to the received phase control unit, the operation processing unit generates a motor-starting processing signal to the first and the second rectifier element for driving a fan motor to rotate. Since the phase control unit provides the effect of controlling the fan motor's output power and rotational speed, it enables the fan to have increased rotational speed and provide improved heat dissipation and ventilation effects.

Abstract: A fan shutter device includes a frame, multiple slats and multiple sleeves. The frame has a first side and a second side, each of which is formed with multiple assembling channels, multiple fixing holes and multiple displacement slots. Each slat has two extension sections and a connection shaft. Each of two ends of the connection shaft is formed with a connection socket. Each sleeve has a pivot pin and a sleeve section. The pivot pin is assembled and connected in the connection socket. Multiple fixing members are respectively passed through the fixing holes to directly fix the sleeves so that the first and second sides are prevented from deforming in assembling process. The slats are spaced from the frame by a gap without abrading with or interfering with the frame. The extension sections are disposed in the displacement slots, which restrict the rotational angle of the slats.
