Embodiment Construction

[0065] Hereinafter, with reference to the drawings, an embodiment related to the surface-mounted vibration motor and the mounting structure of the surface-mounted vibration motor of the present invention will be described in detail with an example shown.

[0066] figure 2 An example of the surface mount type vibration motor 1 is shown. Such as figure 2 As shown, on the outer circumference of the cylinder of the vibration motor main body 2, a motor frame 5 made of, for example, heat-resistant elastic silicone rubber, which covers the motor case, is mounted. The motor frame is 5 single-piece, which looks like image 3 with Figure 4 The irregular roughly cylindrical shape shown is provided with a motor holding portion 5a and a motor support portion 5b integrally formed of a resin member or an elastic member, and the bottom surface portion is integrally formed with the end surface of the above-mentioned motor support portion 5b A comb-shaped metal joint 6 is formed.

Abstract

The invention provides a surface mounting structure of a surface mounting type vibrating motor simple in holder structure and capable of stably connecting power supply by increasing the strength of aconnection part against dropping impact and preventing the connection part from being peeled off by the dropping impact to recover the weak points of that motor. This surface mounting type vibrating motor is so formed that a part of a motor holder is fixedly joined onto a circuit board by reflow solder. The motor holder comprises a motor holding part formed of an integrally molded heat resistant resin member or elastic body member and holding a motor body therein by covering the outer periphery of the motor body and a motor support part disposed on the opposite side of the motor holding part and the substrate. A metal joining part soldering the motor support part to the substrate is integrally formed at the substrate side one end part of the motor support part.

Description

Technical field [0001] The present invention relates to a surface mount type vibration motor and a fixing structure of the surface mount type vibration motor. In particular, it relates to a surface mount type vibration motor having a motor frame soldered on a circuit board, and a mounting structure of the surface mount type vibration motor , And a portable communication device with the motor. Background technique [0002] In recent years, electronic components used in electronic devices and the like have been designed as surface-mounted circuit boards using reflow soldering in many cases in assembly production. Such electronic components are placed on a predetermined position on a circuit board printed with cream solder, and after being heat-treated with the cream solder melted in a heating furnace, each electronic component is fixed on the circuit board. [0003] In addition, similar to the above-mentioned electronic parts, vibration motors used in some portable communication dev...
