Problems solved by technology

[0002] The traditional sounding unit includes a moving iron unit, a shielding shell and a sounding tube. The moving iron unit is the main part of the sound. The moving iron unit includes a diaphragm and a magnetic drive mechanism. The mechanical strength of the pivot device is used to determine the audio level of the sounding unit, but such a method is not only difficult to implement, but also has a high cost

Embodiment 1

[0025] see figure 1 , as shown in the legend therein, a diaphragm applied to a mid-high frequency sounding unit, the diaphragm includes a diaphragm main body 1, a connecting part 2, a diaphragm support 3 and a prestressed film 4, the diaphragm The main body 1 includes a front side and a back side; the front side or the back side is in contact with the prestressed film 4; the diaphragm main body 1 is provided with a circular recess 11; the prestressed film 4 is fixed and tightly sealed on the diaphragm support 3; One end of the membrane main body 1 is connected to the diaphragm holder 3 through the connecting portion 2 .

[0026] The recessed depth of the recessed part 11 is 1 / 3 of the thickness of the diaphragm main body 1 .

[0027] Preferably, the concave part is circular, elliptical, triangular, prismatic, rectangular or irregular.

[0028] The diaphragm main body 1 , the connection part 2 and the diaphragm holder 3 are made of aluminum.

[0029] The thickness of the con...

Embodiment 2

[0034] see figure 2 , as shown in the legend therein, the rest is the same as that of Embodiment 1, the difference is that the cross-section of the concave portion 11 is elliptical, and the cross-sectional area of ​​the concave portion 11 is 50% of the area of ​​the diaphragm main body 1.

Embodiment 3

[0036] see image 3 , as shown in the legend therein, the rest is the same as that of Embodiment 1, except that the cross section of the recessed portion 11 is rectangular.

Abstract

The invention discloses a diaphragm with a function for improving medium and high frequency sounding. The diaphragm comprises a diaphragm main body, a connection part, a diaphragm bracket and a pre-stress thin film, wherein the diaphragm main body is attached to and contacted with the pre-stress thin film and is provided with a sunken part; the pre-stress thin film is fixedly tensioned and sealed on the diaphragm bracket; one end of the diaphragm main body is connected to the diaphragm bracket through the connection part; and by arranging the sunken part on the diaphragm of a sounding unit, the rigidity of the diaphragm is not reduced and the weight is relieved, so that the sounding unit has medium and high frequency audio frequency. The invention also discloses a preparation method of the diaphragm.

Description

technical field [0001] The invention relates to a vibrating membrane, in particular to a vibrating membrane with the function of improving mid-high frequency pronunciation and a preparation method thereof. Background technique [0002] The traditional sounding unit includes a moving iron unit, a shielding shell and a sounding tube. The moving iron unit is the main part of the sound. The moving iron unit includes a diaphragm and a magnetic drive mechanism. The level of the audio frequency of the sounding unit is determined by the mechanical strength of the pivot device, but such a method is not only difficult to implement, but also has a high cost. Contents of the invention [0003] In order to solve the above problems, the present invention provides a diaphragm with the function of improving middle and high frequency sound. [0004] The technical scheme of the present invention is as follows: a diaphragm with the function of improving middle and high frequency pronunciati...
