Embodiment Construction

[0014] Please also refer to figure 1 with 2 , an electronic device 100 with a sound output function, comprising an upper cover 10, a lower cover 20 and a display unit 30, the upper cover 10 and the lower cover 20 are engaged to accommodate the display unit 30 therein. The electronic device 100 is also equipped with a speaker 40 (see Figure 4 ), the horn 40 is fixed on the inner surface of the upper cover 10, and when the upper cover 10 and the lower cover 20 are engaged, the horn 40 is accommodated in the closed space formed by the upper cover 10 and the lower cover 20. A speaker hole 101 is provided at a position corresponding to the speaker 40 on the upper cover 10 , and the sound from the speaker 40 is transmitted through the speaker hole 101 . The display unit 30 is a display screen such as an LCD. The electronic device 100 can be any device equipped with a speaker, such as a portable TV, VCD / DVD player, and the like.

Abstract

An electronic device includes a front frame that includes a planar portion, a first sidewall, and a second sidewall opposite to the first sidewall, the first sidewall and the second sidewall protruding from the planar portion. A back cover is coupled to the front frame. A speaker is attached to the front frame adjacent to the second sidewall of the front frame. The front frame includes several spaced first hooking members arranged on the first sidewall and the back cover includes several spaced second hooking members respectively engaged with the corresponding first hooking members. The first hooking members are used for cooperatively causing a natural frequency of the first sidewall to be greater than a resonance frequency of the speaker, thereby reducing noises caused by resonant vibration of the first sidewall induced by the speaker.

Description

technical field [0001] The invention relates to an electronic device, in particular to an electronic device with a sound output function. Background technique [0002] Existing electronic devices, such as VCD / DVD players, portable televisions, etc., are all provided with speakers, through which audio and video files can be played. However, when the speaker emits sound through vibration, the electronic device itself may cause vibration to generate noise, thereby affecting the sound quality of the sound emitted by the speaker. Contents of the invention [0003] In view of this, it is necessary to provide an electronic device with sound output function, and the structure of the electronic device itself will not generate noise due to vibration to affect the sound from the horn, so as to solve the above problems. [0004] The electronic device with sound output function includes an upper cover, a lower cover, a display unit and a speaker. The upper cover and the lower cover ar...
