Novel vibration motor of mobile phone

Abstract

The novel mobile phone vibrating motor disclosed by the present invention comprises a flat spherical casing on one side, a rotor is arranged in the middle of the casing, and coils are arranged under both sides of the rotor. The flat side of the shell forms a large angle space above the rotor between the upper ends of the coils. A large vibrator is arranged in the large angle space. The large vibrator includes a small main body and a large cover body, and the small main body is located directly above the rotor. Between the upper end of the coil and the upper end of the coil, the large cover of the large vibrator is covered on the upper part of the small main body. The present invention increases the angle space between the upper ends of the coils by putting the coil upside down in the casing, and at the same time enlarges the vibrator cover body and reduces the vibrator main body, so that the angle space can accommodate the large vibrator. Due to the shape change of the small main body and the large cover body, the weight and eccentric distance of the vibrator between the small main body and the large cover body are increased, and the vibration performance of the vibration motor of the mobile phone is improved.

Description

technical field [0001] The invention relates to the field of mobile phone components, in particular to a novel mobile phone vibration motor. Background technique [0002] In recent years, with the progress of society and the improvement of living standards, mobile phones have become an indispensable tool in people's daily life by virtue of their mobile communication, convenient and quick features. In order to prevent missed calls and enhance reminders in noisy environments, mobile phones are equipped with a vibration function. When the mobile phone has an incoming call or text message, the mobile phone will vibrate, so that the user can feel its action, so as to achieve the purpose of prompting the call or text message in time. . [0003] Mobile phone vibration is realized by the vibration motor built in the mobile phone. At present, as the mobile phone body is becoming more and more thin and light, the traditional mobile phone vibration motor is limited by the space of the...

[0003] Mobile phone vibration is realized by the vibration motor built in the mobile phone. At present, as the mobile phone body is becoming more and more thin and light, the traditional mobile phone vibration motor is limited by the space of the PCB, and the shape of the vibrator is difficult to change. As a result, the weight of the vibrator is relatively small, the eccentric distance is small, and it occupies a large space in the structure of the mobile phone, which is increasingly unable to meet the needs of light and thin design

For example, the general structure and installation method of vibration motors in mobile phones on the market today are as follows: figure 1 As shown, the mobile phone vibration motor includes a flat spherical casing 1 on one side, a rotor 2 is provided in the middle of the casing 1, and a coil 3 is provided on both sides of the rotor 2, and the upper end of the coil 3 located in the upper part of the casing 1 faces Closed in the middle, a vibrator 4 is provided above the rotor 2, the main body 41 of the vibrator 4 is located directly above the rotor 2 and between the coil 3, and the cover 42 of the vibrator 4 is set on the main body The upper part of 41, as can be seen from the above structure, because the coil 3 of the traditional mobile phone vibration motor is located above the two sides of the rotor 2, and the upper end of the coil 3 is retracted towards the middle, so the angle between the upper ends of the coil 3 is very small, thereby limiting the position of the vibration motor located here. The shape of the vibrator 4 makes the weight of the vibrator 4 relatively small and the eccentric distance is small, resulting in poor vibration performance of the vibration motor
