Abstract

A directional condenser microphone having a shape of parallelepiped is disclosed. The condenser microphone comprises a case formed in a square box shape, the case having an open surface and a closed bottom surface which is formed with sound holes for collecting sound; a diaphragm member formed in a ring shape, the diaphragm member being inserted into the case; a thin spacer formed in a ring shape; a cylindrical insulating ring having an open top and bottom portions; a back plate formed in a disk shape and having sound holes therethrough; an annular conductive ring for electrically connecting the back plate to a PCB; and the PCB formed in a square plate shape, the PCB having electronic components mounted on one surface of the PCB and projecting terminals formed on the other surface thereof, the PCB being formed with a sound hole for rear sound in the central portion thereof. Here, the diaphragm member, the spacer, the insulating ring, the back plate, the conductive ring, and the PCB are sequentially arranged in the case and then the condenser microphone is integrally assembled by curling an end of the case.

Figure 10 is a side cross-sectional view showing the assembly of the fourth to sixth embodiments of the present invention. Those reference numerals of the fourth embodiment are used to representatively represent the reference numerals of these components. With reference to the eighteenth diagram, the unidirectional capacitive transmissions of the fourth to sixth embodiments 400 to 600 each have a case-shaped outer casing 1〇2 in which a diaphragm member 404 and a spacer 406 are sequentially disposed. The mask ring 408, the back plate 41, the acoustic resistor 411, the integral substrate 412, and the pcB 414 formed in the shape of a square plate. The condenser microphone is then assembled by crimping the ends of the outer casing 402. Overhanging terminals are formed on the exposed surface of the PCB 414 and these protruding terminals protrude more than the curved surface, so that the capacitive coolers 400 to 600 can be mounted on the main PCB (for example, the pcB of the cellular phone) in the method . The terminal strips can be the terminals for the connection and the ground terminal and the terminals required for the additional function. Further, the square members of the fourth to sixth embodiments may have edges formed in contact with each other in accordance with the convenience of manufacture and assembly of these members. ICs mounted in the PCB include junction field effect transistors (jfets), amplifiers, ship-to-digital (A/D) converters (4), or 1C ASICs as material-sensing amplifiers and analog-to-digital (A/D) converters. Next, the operation of the condenser microphone of the fourth to sixth embodiments will be carried out. 24 1279157 • The projecting terminal 416 of the condenser microphone according to the present invention is connected to the connection terminal of the main PCB. Which energy is added to these protruding creepers. Therefore, in the condenser microphone according to the present invention, the diaphragm 4 is plopped, the outer casing 402 and the pole ring 404a are electrically connected to the PCB 414, and the back plate 41 is electrically conductive through the ear blocking 611 and the integral substrate 412. Layer 4] This and? (: State 4 electrical connection. In this case, the front sound from the external sound source flows into the inside of the microphone through the sound hole 4023 of the casing and is transmitted to the diaphragm. 后面. Back sound through the sound hole 414a of the PCB 414 And then it is weakened or changed to have a different phase by the acoustic resistor 411. The sound passing through the acoustic resistor 411 is transmitted through the sound hole 41〇a of the back plate 410 to the diaphragm 4〇4b. At this time, since the rear sound is The varistor 411 is weakened, so that the diaphragm is only responsive to the front sound. Therefore, the diaphragm 404b vibrates under the action of the sound of the front sound. As a result, the gap between the diaphragm 404b and the backing plate 410 can be changed by the membrane. The electrostatic capacitance generated by the chip 4〇4b and the back 1410 will change, so that the Lu electrical signal (voltage) can be changed according to the acoustic wave. The signal is transmitted along the above electrical connection path to the IC mounted in the PCB 414. Thereby amplified and then rotated out to the external circuit through the extension terminal 416. _, in the above embodiment, it is noted that since the central portion of the bottom surface of the outer casing is used for the processing of the SMD, the vacuum chuck is used from the strip-roll The position of the microphone is accurately picked up, so that the casing does not form a sound hole. Industrial Applicability As described above, the condenser microphone according to the present invention provides directivity. Further, since the component 25 1279157 can be confirmed during the processing of the surface mounting device (10) The direction, so that two or more connection terminals of the component can be easily adjusted to each other. Therefore, this can prevent the connection surface of the connection terminal of the main PCB and the connection terminal of the condenser microphone from deviating, and also reduce the connection failure due to the connection or the direction (polarity) of the connection terminal. While the invention has been described with reference to the preferred embodiments of the present invention, it will be understood by those skilled in the art Various changes or changes.
