Embodiment 1

[0042] Example 1: see figure 1 , the microphone 1 of this embodiment is combined by two pickups 2 and 2' arranged side by side, the sound receiving ends 3 and 3' of the two pickups 2 and 2' are in the same direction, that is, facing the same direction and the end faces 4 and 4' are located at the same Plane, the two pickups 2 and 2' are omnidirectional circular pickups, the sides of which are glued together to form the pickup array microphone of the present invention, and the distance between the centers of the two pickups is less than 10mm. In this embodiment, the two pickups 2 and 2' each have two terminal pins 5, 5' and 6, 6', and the respective terminal pins of the two pickups 2 and 2' can be connected to different terminal posts or wires respectively to form an acoustic Two independent signals that do not interfere with each other on the circuit and the circuit to meet the needs of different application functions. For example, if one of the pickups is connected to a dela...

Embodiment 2

[0043] Example 2: see figure 2 , the microphone 1 is composed of two pickups 2 and 2' arranged side by side. The voice receiving ends 3 and 3' of the two pickups 2 and 2' face the same direction and the end faces 4 and 4' are on the same plane. The two pickups 2 and 2' 2' are all omnidirectional pickups, and they are covered with packaging materials, that is, the two pickups 2 and 2' are combined by the packaging 7 to form the pickup array microphone of the present invention. The ground pins 5' and 6' of the two pickups 2 and 2' of the present embodiment are connected together to form three ground pins. The outside of the package 7 of this embodiment can also be provided with a cover, and the end faces of the cover corresponding to the end faces 4 and 4' of the sound receiving ends 3 and 3' are provided with ventilation holes. Packaging 7 can be made of metal skin or plastic. Two omnidirectional pickups 2 and 2' of the present embodiment can be standard 6mm or 9.6mm pickups...

Embodiment 3

[0044] Embodiment 3: see image 3 and Figure 4 . The two pick-ups 2 and 2 ' that present embodiment arranges side by side are the semi-cylindrical pick-ups of half of common pick-up respectively, are to arrange section 8 to form two semi-cylindrical hollows completely isolated from each other in the cylinder of the size of a circular pick-up Cavities, and add materials such as vibrating membranes, transistors, and electrodes to each semi-cylindrical cavity to become an independent omnidirectional pickup. The spacer 8 in this embodiment is a T-shaped spacer. Figure 4 yes image 3 The rear view of , shows a way of setting the connection pins, that is, the ground pins 5' and 6' are connected together to form three ground pins.

Abstract

The invention relates to a miniature embeddable pick-up array microphone and its application. The microphone of the present invention includes two pickups combined into one, and the two pickups are omnidirectional pickups. The microphone of the present invention has simple structure, low production cost, convenient installation and use, can be miniaturized, can be embedded in various devices, and can meet various functional requirements; the present invention also relates to the setting method of the microphone, and also relates to the application of the microphone , including providing handheld devices, display devices, microphones, tape recorders, hearing aids and car rearview mirrors using the microphone.

Description

Technical field: [0001] The invention relates to a microphone, in particular to a miniature embeddable pickup array microphone and its application. Background technique: [0002] A pickup is included in the shell of the present general microphone (microphone), and two connecting pins are drawn out at the lower end of the pickup. And some special-purpose microphones that only contain a pickup are in order to achieve specific functions, such as in order to produce a directional function, in addition to using a directional pickup, it is also necessary to open more holes on the shell of the microphone, which increases the complexity of its structure. High cost and increased volume. And since the holes at each position of the microphone must have enough sound waves to enter, the holes are required to be large enough to ensure the smooth flow of air, and its application range is greatly limited. For example, it cannot be used in devices and environments with embedded single-side...
