Description

Technical Field

[0001] This utility model relates to the technical field of electronic cigarette microphones and electret microphones, specifically, to a microphone with a simplified structure that does not employ electrode plates and gaskets. Background Technology

[0002] A parallel-plate capacitor consists of two parallel metal conducting plates separated by a dielectric material. When a potential difference exists between the plates, an electrostatic field is generated between them. A uniform electric field exists between the plates, and due to edge effects, the electric field lines at the capacitor's edges are curved and divergent. The parallel-plate capacitor is the simplest type of capacitor; any non-parallel-plate capacitor can be considered as a combination of several small parallel-plate capacitors connected in series and parallel.

[0003] The conventional parallel plate capacitor's three-component structure effectively reduces the number of components, greatly improves assembly efficiency, and lowers material and labor costs. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned traditional technologies and provide a simplified microphone with a simple structure that does not use electrode plates and gaskets.

[0005] The objective of this utility model is achieved through the following technical measures:

[0006] A simplified microphone design that does not employ electrode plates and gaskets is characterized by: including a housing assembly, the housing assembly including a housing base plate, a housing side wall fixedly connected to the upper surface of the housing base plate, a housing boss fixedly connected between the housing side wall and the outer floor, a plastic ring connected to the upper surface of the housing boss, a nickel ring film sleeved inside the plastic ring, a PCBA assembly connected to the upper surface of the plastic ring, a hollow hole opened in the housing base plate, and a dustproof mesh fixedly connected to the lower surface of the housing base plate.

[0007] As an improvement: the base plate of the outer casing and the outer casing boss form an electrode cavity.

[0008] As an improvement: the base plate of the housing and the boss of the housing form a PCBA mounting cavity, and the PCBA assembly is located in the PCBA mounting cavity.

[0009] As an improvement: the hollow hole forms a hollow cavity, and the hollow cavity, the electrode plate cavity, and the PCBA mounting cavity are connected.

[0010] As an improvement: the PCBA assembly includes an FR epoxy resin board, which is fixedly connected to the upper surface of the housing boss.

[0011] As an improvement, the FR epoxy resin board is electrically connected to a FET chip, a capacitor, and a resistor, respectively.

[0012] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0013] The design replaces the traditional electrode plates and gaskets with a raised outer shell, thereby reducing the number of traditional electrode plates and gaskets and improving the precision of the fit, which meets the requirements of a resource-saving society. The parallel plate capacitor is composed of the outer shell base plate, outer shell side wall and nickel ring film, which receives the capacitance change signal and transmits it to the chip in the PCBA assembly for signal monitoring through the metal structure.

[0014] By designing circuit connection lines and electrodes on a set FR4 epoxy resin board, and attaching FET chips, capacitors, and resistors to the FR4 epoxy resin board to form a related circuit with signal output function, the function of a traditional parallel plate capacitor is realized. The outer shell assembly is a metal structure, which serves to protect the structure, provide support, and connect one electrode of the capacitor.

[0015] By reducing structural complexity, the number of parts is effectively reduced, greatly improving assembly efficiency and lowering material and labor costs. Attached Figure Description

[0021] Example: Figures 1 to 4As shown, a simplified microphone design without electrode plates and gaskets includes a housing assembly 1. The housing assembly 1 includes a housing base plate 11. A housing side wall 12 is fixedly connected to the upper surface of the housing base plate 11. A housing boss 13 is fixedly connected between the housing side wall 12 and the outer floor. A plastic ring 2 is connected to the upper surface of the housing boss 13. A nickel ring film 3 is sleeved on the inner side of the plastic ring 2. A PCBA assembly 4 is connected to the upper surface of the plastic ring 2. A hollow hole 14 is opened on the housing base plate 11. A dustproof mesh 5 is fixedly connected to the lower surface of the housing base plate 11.

[0022] The base plate 11 of the outer casing and the outer casing boss 13 form an electrode cavity 6. By replacing the traditional gasket and electrode plate with the outer casing boss 13, the electrode cavity 6 achieves the functions of the traditional gasket and electrode plate, effectively reducing the number of parts, greatly improving assembly efficiency, and effectively reducing material and labor costs.

[0023] The base plate 11 and the boss 13 of the outer casing form a PCBA mounting cavity 8, and the PCBA assembly 4 is located within the PCBA mounting cavity 8. The PCBA mounting cavity 8 facilitates the installation and placement of the PCBA assembly 4 and provides stability to the PCBA assembly 4.

[0024] The hollow hole 14 forms a hollow cavity 7, which is connected to the electrode plate cavity 6 and the PCBA mounting cavity 8. The hollow cavity 7 and the electrode plate cavity 6 are connected to realize the function of a parallel plate capacitor, and the dustproof mesh 5 can also prevent dust from entering the hollow cavity 7.

[0025] The PCBA assembly 4 includes an FR4 epoxy resin board 41, which is fixedly connected to the upper surface of the housing boss 13. An FET chip 42, a capacitor 43, and a resistor 44 are electrically connected to the FR4 epoxy resin board 41. By designing circuit connection lines and electrodes on the FR4 epoxy resin board 41 and attaching the FET chip 42, capacitor 43, and resistor 44 to the FR4 epoxy resin board 41, a related circuit is formed, providing signal output. This achieves the function of a traditional parallel plate capacitor. The housing assembly 1 is a metal structure, serving to protect and support the structure.
