Problems solved by technology

[0004] The above example is to construct an array microphone in an open space, and there is no difficulty in practical application. However, most electronic devices (such as Cellular Phone, Personal Digital Assistant, PDA, Notebook Computer, etc.) have Plastic or metal shells, these shells have the effect of isolating sound, making it difficult for the microphone set in the shell to receive external sound
Therefore, the performance of the array microphone, which originally performed well in an open space, once installed in an electronic device, due to the obstruction of the casing, its performance deteriorates significantly.

Embodiment Construction

[0097] see Figure 2A , the electronic device of the present invention is a notebook computer 2 in the first embodiment, and its casing 20 includes a front cover 21 and a rear cover 22, and a plurality of sound receiving holes 211 are arranged on the front cover 21, and the external sound can pass through The acoustic hole 211 enters the casing 20 .

[0098] Figure 2B yes Figure 2A The sectional view of the notebook computer taken along the section line IIB-IIB, by Figure 2B It can be seen that a circuit board 23 , a flexible casing 26 and a plurality of microphones 24 are disposed inside the casing 20 of the notebook computer 2 .

[0099] see Figure 2C , the front cover 21 has a plurality of convex walls 214 , and the convex walls 214 protrude inward to form a plurality of accommodating spaces 212 , that is, the convex walls 214 surround the accommodating spaces 212 . The receiving space 212 communicates with the sound receiving holes 211 on the front cover 21 , and ...

Abstract

An electronic device includes a front cover, a circuit board, a plurality of flexible holders, and a plurality of microphones. The front cover includes a plurality of wall portions, a plurality of storage spaces encircled by the wall portions, and a plurality of acoustic openings connecting to the storage spaces. The flexible holders have hollow bodies squeezed into the storage spaces. The microphones are electrically connected to the circuit board and squeezed into the hollow bodies of the flexible holders.

Description

technical field [0001] The invention relates to an electronic device, in particular to an electronic device with a built-in array microphone. Background technique [0002] Array Microphone can clearly receive sound from a specific direction while suppressing ambient noise, so it is usually used in high-quality audio recorders or communication devices. [0003] A typical array microphone consists of several parallel microphones. figure 1 The simplest example of an array microphone is shown, wherein the array microphone 10 includes two microphones 11, 12 arranged side by side. The two microphones 11, 12 receive signals, and after processing, the directivity of the array microphone 10 can be determined ( Directivity). Assuming that the two microphones 11 , 12 are omni-directional microphones and have the same characteristics, the directivity of the array microphone 10 is determined by the distance D1 between the two microphones 11 , 12 . [0004] The above example is to cons...
