Electronic products equipped with longitudinal vibration motors

Abstract

The invention discloses a longitudinal vibration motor-equipped electronic product which comprises a product outer shell and a longitudinal vibration motor, wherein the longitudinal vibration motor is fixed in the product outer shell; the longitudinal vibration motor comprises a shell body, a vibration block assembly, elastic sheets and a circuit assembly; the shell body has an accommodating chamber, the shell body and the accommodating chamber are shaped like a cuboid or have a structure similar to the cuboid, the vibration block assembly is arranged in the accommodating chamber, the vibration block assembly comprises a mass block and a magnet, each of upper and lower sides of the vibration block assembly is at least provided with at least one elastic sheet, the elastic sheets extend along a direction of a long axis of the vibration block assembly, the circuit assembly comprises a wire coil and an external circuit, and the wire coil is arranged on a side surface of the magnet; when the vibration block assembly is at an equilibrium position, the wire coil directly faces the magnet, upper and lower edges of the magnet correspond to a position of a cross section of the wire coil, the wire coil is connected with the external circuit, and the external circuit is electrically connected with the electronic product. The longitudinal vibration motor is configured in the product outer shell in such a way that the vibration block assembly is enabled to vibrate along a thickness direction of the electronic product.

Description

technical field [0001] The invention belongs to the technical field of electronic products, and in particular, the invention relates to an electronic product equipped with a longitudinal vibration motor. Background technique [0002] With the gradual development of electronic product technology, vibration motors have become commonly used functional devices in electronic products such as mobile phones and tablet computers. Micro vibration motors mainly include rotor motors and linear vibration motors, among which, the cylindrical rotor motor is small in size and can be assembled by SMT process, but its performance is not as good as that of linear vibration motors. Linear vibration motors have many advantages in tactile feedback applications, such as high vibration, low resonance frequency, low power consumption, fast response, and high space utilization. They are widely used in electronic products. Among the linear vibration motors, the motor technology of the horizontal vib...

Problems solved by technology

However, most of the existing longitudinal linear vibration motors have a circular structure and occupy a large space, so they are not suitable for use in miniaturized electronic products.

Furthermore, the shrapnel of the existing longitudinal vibration motors usually has a helical structure. Although this structure can provide balance, stable support and rebound force for the disc-shaped and cylindrical longitudinal vibration motors to a certain extent, if the The vibrating block of the motor is set in a rectangular shape or other shapes. This kind of shrapnel cannot provide stable support, and the force of the rebound is prone to unbalanced linearity, which may easily cause polarization.

[0004] On the other hand, the miniature vibration motor is small in size and is easily damaged when assembled in electronic products. The existing fixing methods often cannot ensure that the vibration motor meets the performance requirements in electronic products.
