Embodiment 1

[0013] as attached figure 1 shown. The vibrating motor for portable electronic equipment disclosed in this embodiment changes the electrode contact structure and installation method of the original portable electronic equipment vibrating motor, which can further reduce the thickness of the space required for vibrating motor installation, and can also increase the stability of vibrating motor installation. and stability of the electrical connection.

[0014] Specifically, the vibration motor includes a motor casing 1 with a stator and a rotor installed therein, and an electrode contact 2 electrically connected to the inner coil of the motor. The electrode contact 2 is a retractable spring and is arranged outside the motor casing 1 at The end of the motor housing 1 opposite to the position of the motor output shaft. The design of the electrode contact 2 reduces the thickness of the overall required space when the vibration motor is installed, so that the portable electronic de...

Embodiment 2

[0017] Another example figure 2 shown. The main structural principle of the vibration motor for portable electronic equipment disclosed in this embodiment is the same as that of the first embodiment, and also includes a motor housing 1 with a stator and a rotor installed inside, and an electrode contact 2 electrically connected to the internal coil of the motor. Point 2 is a stretchable spring, which is arranged outside the motor casing 1 and is located at the end of the motor casing 1 opposite to the output shaft of the motor. The design of the electrode contact 2 reduces the thickness of the overall required space when the vibration motor is installed, so that the portable electronic device can be made thinner. In order to facilitate the installation of the electrode contact 2, a connecting plate 3 is provided on the motor casing 1, the inner end of the connecting plate 3 is fixed on the motor casing 1, and the outer end is bent and extended parallel to the motor axis towa...

Abstract

The invention discloses a vibration motor small in mounting space of portable electronic equipment. The vibration motor comprises a motor housing, and electrode contacts electrically connected with a coil in the motor, wherein a stator and a rotor are mounted in the motor housing, and the electrode contacts are telescopic springs or elastic sheets, and are arranged outside the motor housing, and positioned at one end, opposite to a position of a motor output shaft, of the motor housing. According to the vibration motor, positions and mounting structures of the electrode contacts are changed, so that the whole vibration motor occupies a smaller and thinner space in a mounting process, the mounting stability of the vibration motor in the portable electronic equipment and the contact stability between each electrode contact and an outside electric conduction part are improved, and the running stability of the whole vibration motor is improved.

Description

technical field [0001] The invention relates to an improved technology for a vibration motor of a portable electronic device. Background technique [0002] With the development of portable electronic devices such as mobile phones, their thickness is getting thinner and thinner. In order to meet such ultra-thin design requirements, the vibration motor inside the portable electronic device also needs to be made smaller and thinner accordingly. The electrode contacts of the existing vibration motors are generally arranged on the side wall, and a certain amount of space is required for installation considering the electrical connection between the electrode contacts and the circuit board, so that the entire vibration motor occupies a large space in the portable electronic device, which is difficult to install. The purpose of further reducing the thickness of the portable electronic equipment is achieved. Contents of the invention [0003] In view of this, the present inventi...
