New Description: [New Technology Field] This book is about a kind of speaker, especially about an electrostatic speaker. [Prior Art] An electroacoustic speaker is a transducer that converts electrical energy into a sound energy output. According to its driving method, it can be classified into three types: moving coil type, piezoelectric type and static type speaker. Currently, dynamic coil speakers are the most widely used, and they have been widely used in televisions, stereos, earphones, and mobile phones. However, dynamic coil speakers are limited in their inherent structure and power design, and cannot meet the portability and low current requirements of electronic products. As for the conventional electrostatic speaker, the high DC bias (1,500V to 2,000V) amplifier is required, and the high cost is not conducive to the application of the portable product. Furthermore, the electrostatic speaker currently published has remained substantially in the form of a planar electrostatic film. Since the change in shape is extremely small, the acoustic response that can be generated is still highly directional, which causes some space limitations in the use of the electrostatic speaker. In view of this, there is an urgent need for an electrostatic speaker that is extremely portable (e.g., folded) and has no directionality (e.g., a cylinder or a sphere). [New content] One of the purposes of this creation is to provide an electrostatic speaker that is extremely portable and has no directionality.

Referring to FIGS. 5A and 5B, the fifth A is a perspective view of a cone electrostatic speaker according to another embodiment of the present creation; the fifth B is based on A cross-sectional view of a cone-shaped electrostatic speaker according to another embodiment of the present invention. The cone-shaped electrostatic speaker 300 of the present invention comprises a front electrode M421661, November 9曰301, a reverse electrode 30Γ, and two electrets including electrodes. The body diaphragms 302, 202' and the two spacers 303, 303'. The method of manufacturing the cylindrical electrostatic speaker 300 will be further explained below. Referring to a fifth C diagram, a fifth C diagram is a cross-sectional view of a first partial cone of a cone-shaped electrostatic speaker according to another embodiment of the present invention. First, an A4 size 150 mesh stainless steel porous conductive back sheet was rolled into a conical shape in which the upper end opening had a radius of 1 cm and the lower end opening had a radius of 5.5 cm and was fixed with a tape as the front surface electrode 301. Thereafter, a spacer 303 having a thickness of 400 / / m is adhered to the inner side of the front electrode 301 in a desired size and pitch. Further, the electret diaphragm 302 is wound by a cloth motor and then curled into a circular cone shape and fixed by a tape. The size of the electret diaphragm 302 is made to match the size of the tapered front electrode 301. After the release paper on the surface of the spacer 303 is peeled off, the electret diaphragm 302 is fixed and adhered to the inner side of the front electrode 301, that is, the first partial cone of the cone electrostatic speaker 300 is completed as shown in FIG. . According to the above method, the second partial cone of the cone electrostatic speaker 300 is shown in FIG. 5D, and the fifth D is a cross-sectional view of the second partial cone of the cone electrostatic speaker according to another embodiment of the present invention. However, the electret diaphragm 302' is on the periphery, and the conical counter electrode (stainless steel porous conductive back plate) 30 is on the inner side, and the second partial cone is smaller in diameter than the first partial cone. The circumference of the electret diaphragms 302, 302' of the first cone and the second cone is adhered to each other by a double-sided tape to complete the structurally symmetrical cone electrostatic speaker 300, as shown in the fifth figure and the The five figures are shown.
