According to the utility model discloses an electron device has good heat-sinking capability.
As shown in the drawings, in the electronic device 100 according to the present invention, by sandwiching the first circuit board 150 between the first cover peripheral portion 184 and the first peripheral wall portion 120a, the first circuit board 150 is substantially enclosed in the space defined by the first cover portion 180, the case base 112, and the first peripheral wall portion 120a. By sandwiching the second circuit board 160 between the second cover plate peripheral portion 194 and the second peripheral wall portion 120b, the second circuit board 160 is substantially enclosed within a space defined by the second cover plate portion 190, the housing base 112, and the second peripheral wall portion 120b. With this structure, the first circuit board 150 and the second circuit board 160 are secured from EMC interference of the external environment, while electromagnetic interference between the first circuit board 150 and the second circuit board 160 is prevented. According to the utility model discloses an electronic device 100 has good EMC performance.
As shown in fig. 4A, 5A, and 5C, the electronics housing 110 also includes a peripheral wall 126 that is outside of the electronics cover plate 170 and adjacent to the electronics cover plate 170. The peripheral wall 126 extends beyond the first cover perimeter portion 184 and the second cover perimeter portion 194 of the electronics cover 170, preferably flush with the first cover center portion 182 and the second cover center portion 192. The peripheral wall 126 can further improve the EMC performance of the electronic device 100 and provide protection to the first circuit board 150, the second circuit board 160, and the electronic device cover plate 170.
According to the utility model discloses an electron device can firmly install two circuit boards simultaneously, and these two circuit boards all have good heat dispersion and EMC performance simultaneously. Compared with the prior art which requires two separate electronic devices to accommodate two such circuit boards, the present invention has the following technical advantages: the number of the die tools is small, the number of required tests is small, the assembly process is saved, and the production cost is reduced. In embodiments where the electronic device is an audio power amplifier, the first circuit board and the second circuit board are two separate audio power amplifying circuit boards that can cooperate to provide better audio power amplification performance. For example, in some embodiments, a first audio power amplifier circuit board (e.g., amplifier) performs audio processing and amplification on an audio signal from an audio source, and a second audio power amplifier circuit board (e.g., boost) receives the audio processed and amplified audio signal from the first audio power amplifier circuit board and further amplifies the audio signal. This configuration can provide more audio channels, drive more speakers, and provide better sound effects, suitable for use in some high-end sound systems.
In the embodiment shown in the figures, the first and second peripheral wall portions 120a, 120b have a common wall portion 122, and the first and second cover plate peripheral portions 184, 194 also have a common peripheral portion 188.

However, the present invention is not limited thereto, and in other embodiments of the present invention, the first peripheral wall portion 120a and the second peripheral wall portion 120b may not include the common wall portion 122, i.e., they are separated, and/or the first cover plate peripheral portion 184 and the second cover plate peripheral portion 194 may not include the common peripheral portion 188, i.e., they are separated.
In the embodiment shown, the electronics housing 110 and electronics cover 170 are shaped to receive the first circuit board 150 and the second circuit board 160. In other embodiments according to the present invention, the electronic device housing and the electronic device cover plate may have other suitable shapes to receive two circuit boards of other shapes.
