Description

A kind of vibrating diaphragm shaped device

Technical field

The utility model relates to a kind of vibrating diaphragm shaped device, belongs to the loudspeaker techniques field of electroacoustic components and parts.

Background technology

Vibrating diaphragm is the vitals of loudspeaker, and traditional vibrating diaphragm forming method all is after adopting heating rod to conduct heat, to make the plastic sheeting that is coated on the vibrating diaphragm mould be subjected to the thermal softening aftershaping, uses the heating rod hot briquetting, and efficient is low and power consumption is big.

Summary of the invention

The purpose of this utility model is that a kind of high and vibrating diaphragm shaped device low in energy consumption of vibrating diaphragm shaping efficiency that makes will be provided.

The utility model realizes that the technical scheme of above-mentioned purpose is, a kind of vibrating diaphragm shaped device, its innovative point is: comprise gas hood, water board, induction iron plate, bracing frame and induction loop, described water board and induction iron plate all are fixed on the bracing frame, described gas hood covers on the water board top, the sidepiece of gas hood has blow vent, blow vent is communicated with the gas hood inner chamber, be furnished with some vibrating diaphragm moulds on the end face of described water board, has the limbers in the water board, the water inlet of limbers and delivery port all are connected with water service pipe, and described induction loop places the bottom of induction iron plate.

Described induction loop is wound into disc.

The limbers of described water board has more than five or five, and each limbers is parallel to each other.

The water service pipe that described each limbers connects, perhaps parallel to each other, perhaps have two at least respectively as water inlet pipe and outlet pipe and remaining water service pipe is U-shaped communicating pipe.

Some vibrating diaphragm moulds of described water board are by equidistantly regularly arranged in length and breadth.

The utility model utilizes electromagnetic induction principle, to the induction loop energising, makes induction iron plate produce heat, make plastic sheeting softening, and, making the plastic sheeting moulding by water board control temperature, use the utility model can be so that the vibrating diaphragm shaping efficiency be high and low in energy consumption.
