Embodiment Construction
[0019] The specific embodiments of the present invention will be further specifically described below through specific embodiments in conjunction with the accompanying drawings.
[0020] The technical scheme that the present invention adopts for solving the above problems is:
[0021] Generally speaking, a micro vibrator using electromagnetic work includes a coil, a permanent magnet, a vibrating body, a casing, an elastic device and a circuit substrate. The coil is fixed inside the casing, and the permanent magnet, vibrating body, elastic device and circuit substrate are all located in the casing. The vibrating body is fixed on the shell through an elastic device, the permanent magnet is fixed on the vibrating body, the circuit board applies an electrical signal to the coil, and the electrified coil drives the permanent magnet through magnetic force to drive the vibrating body to vibrate.

The invention discloses a micro vibrator with high sensitivity and high vibration feeling. The micro vibrator comprises a coil, a permanent magnet, a vibration body, a shell, an elastic device and a circuit substrate, wherein the coil comprises an upper coil and a lower coil, the upper coil is fixedly arranged at an inner side of a top end of the shell, the lower coil is fixedly arranged at an inner side of a bottom end of the shell and is opposite to the upper coil, the permanent magnet is suspended between the upper coil and the lower coil, and the permanent magnet is driven to drive the vibration body to vibrate by a magnetic field generated by matching of the upper coil and the lower coil. The micro vibrator has the essential effects that the time of the micro vibrator reaching set vibration feeling is reduced by the magnetic field generated by matching of the upper coil and the lower coil, so that the response time is reduced, and the micro vibrator is more flexible and is higherin vibration feeling; a U-shaped spring sheet with an opening part where a spring is arranged is used as the elastic device, so that the vibration feeling of the micro vibrator is higher, and the service lifetime of the micro vibrator is prolonged; and by adjusting a loading current on the two coils, the vibration mode of the micro vibrator is richer, and a user experience is further enhanced.
Description
technical field [0001] The invention relates to a micro-vibrator using electromagnetic work, in particular to a micro-vibrator with high sensitivity and high vibration sensitivity. Background technique [0002] As a kind of micro motor, the micro vibrator is mainly used in small electronic products such as mobile phones and electric toys. Especially entertainment such as mobile games on smart phones requires vibration to improve the game experience. However, the traditional flat motor is Wear and tear, the service life is short, and it takes a long time to achieve a certain vibration feeling, and the vibration feeling is not strong. While smartphones are getting bigger and bigger, the space to install microvibrators is getting smaller and smaller. The traditional micro-vibrator can no longer meet the needs of customers, so it is necessary to design a micro-vibrator with high sensitivity and high vibration sensitivity to meet the needs of the market.
