Abstract:
An electret capacitor microphone with one-piece vocal cavity component includes; a shell, a vibration element and a circuit board which is used to envelop the shell containing cavity and connect with the shell; the first vocal cavity is formed between the vibration element and the inner surface of the top of the shell; voice holes are connected with the first vocal cavity; wherein, one-piece vocal component that lies between the vibration element and circuit board is installed in the shell. The one-piece vocal cavity component is formed by an annular sidewall and a cavity board formed in one-piece on the annular sidewall. A through-hole is formed on the cavity board and inner concave at lower end of an annular sidewall. The second vocal cavity is formed between the annular sidewall and the cavity board. An external surface of the annular sidewall is coated with an insulating material layer.

Abstract:
Disclosed are a matching device and a matching method for electronic atomization device based on mobile terminal. The device includes a Bluetooth control module, an information reading module, an information transmission module and a comparing and matching module. The method includes steps of: building a Bluetooth connection between battery and mobile terminal; controlling the battery to read identification information of identification chip of atomizer; sending the identification information to the mobile terminal via Bluetooth and then carrying out a match by comparing the atomizer identification information and original identification information; and carrying out a match by comparing the identification information and original identification information. By connecting the electronic atomization device with mobile terminal via Bluetooth and by means of powerful computing ability of the mobile terminal, match between the battery and atomizer of electronic atomization device can be achieved on the mobile terminal directly.
