Portable mobile terminal

Abstract

The invention discloses a portable mobile terminal. The portable mobile terminal comprises a shell and function modules positioned in the shell, wherein at least one function module consists of at least two parts; a first part of the at least two parts is a portion of the shell; and the at least one function module is a built-in sound box or heat-dissipation module. In the portable mobile terminal, at least one function module is directly connected with the shell with no need of a local part, overlapping with the shell, on the mounting side of the at least one function module, so as to form an integral module by using a corresponding part of the shell as the substitute of the unnecessary local part. Therefore, the thickness of the portable mobile terminal can be reduced as much as possible on the premise of ensuring the functions, and the portable mobile terminal is lighter and thinner.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to a module layout design of a portable mobile terminal. Background technique [0002] With the popularization of electronic equipment such as notebook computers, thin and portable has always been one of the most important development directions. Electronic equipment with a highly thin design has smaller volume and lighter weight. At the same time, consumers' requirements for product performance Therefore, how to take into account the function and performance of the product in the ultra-thin design has always been a major technical problem that plagues the development of electronic equipment. [0003] Take the speaker as an example. The speaker is an extremely important part of the sound system of most electronic equipment. Its function is to convert the electrical signal into an acoustic signal and radiate it to the space for people's ears to listen directly. Playback ...

Problems solved by technology

[0010] As shown in the figure, the resonant box 1 is a triangular shape with one side being arc-shaped in section, and is surrounded by integrally formed bottom plate 1-1, side plate 1-2, arc-shaped plate 1-3 and end plate 1-4. It is not difficult to see that in the case of limited space, the thinner the volume of the resonance box, the larger the proportion of the space occupied by the cavity wall, resulting in the decrease of the sound effect of the speaker under the same space conditions.

In this regard, although the space occupied by the cavity wall can be reduced by reducing the thickness of the cavity wall, when the thickness of the cavity wall is reduced to a certain extent, it cannot be further reduced. It is already difficult to improve the sound effect due to the thickness of the wall

[0011] In the same way, this defect also exists in the audio system of the mobile phone. Since the volume of the mobile phone is smaller and the thickness is thinner, the design requirements for the speaker are more stringent. Degree

[0012] Of course, not only speakers, but other modules (such as heat dissipation modules) are also difficult to balance the contradiction between volume and function among many components of portable mobile terminals. In most cases, only the advantages of one aspect can be retained. , on the other hand, there is a disadvantage
