Embodiment
The present invention provides a kind of portable terminal, and is clearer, clear and definite for making the object of the invention, technical scheme and effect, below with reference to accompanying drawing and give an actual example to further explain of the present invention.
Extremely shown in Figure 6 like Fig. 3, the speaker base of portable terminal provided by the invention, its portable terminal comprises: main frame fore shell 110, main frame back cover 120, LCD display 130, motherboard 140, loud speaker 150 and speaker base 160.Said LCD display 130 is arranged on the below of main frame fore shell 110; Motherboard 140 is arranged on the below of LCD display 130; Main frame back cover 120 is arranged on the below of motherboard 140, and said LCD display 130 and said motherboard 140 range upon range of settings, and said main frame fore shell engages with the main frame back cover; Said loud speaker 150 is arranged on the speaker base 160, and the mounting means of other parts of portable terminal can be referring to the conventional mounting method.
The end of portable terminal of the present invention is provided with the cavity 170 that is centered on by main frame back cover and motherboard, and speaker base 160 is arranged in the said cavity 170, and is as shown in Figure 5.Be specially: the part of speaker base 160 is arranged in the space between motherboard 140 and the main frame back cover 120 (not marking among the figure), and another part of speaker base is arranged in the space between main frame fore shell 110 and the main frame back cover 120 (not marking among the figure).The present invention adopts a kind of like this sunk type design with loud speaker; That is: loud speaker is arranged on the below of motherboard 140, makes the compact conformation of portable terminal, reduced the length of portable terminal; Satisfy the compact requirement of portable terminal, improved the competitiveness of product on market.And the main frame fore shell 110 and the main frame back cover 120 of portable terminal are provided with penetrable sound hole 180 and 190, and said penetrable sound hole 180 is communicated with said 170 cavitys and outside air with penetrable sound hole 190, and the sound that loud speaker is sent can pass to the portable terminal outside.
The present invention sends out portable terminal and also the structure of speaker base improved, and is as shown in Figure 6.160 are provided with an annular protuberance 161 on said speaker base, and said loud speaker is arranged in the annular ring of said annular protuberance, and said annular protuberance can be fixed on loud speaker on the speaker base, prevents that loud speaker from sliding on speaker base.Said annular protuberance 161 be made as annular, in other embodiments, annular protuberance can also be made as square, triangle specifically can be according to the shape setting of loud speaker 150, but the size of annular ring of the present invention is as the criterion can hold loud speaker.
In order to make portable terminal that a desirable audio arranged, the loud speaker of portable terminal of the present invention comprises two sound chambeies, sound chamber and sound chamber (not marking among the figure), back before being respectively.And; In order to realize that the sound in sound chamber and sound chamber, back passes to the portable terminal outside through penetrable sound hole 180 and 190 before the loud speaker; Portable terminal of the present invention is provided with division board 162 on speaker base 160, said division board 162 is separated into two parts with said cavity 170; A part is: the space (not marking among the figure) between speaker base 160 and motherboard 140 and the main frame fore shell 110; This segment space is the passage in sound chamber before the loud speaker, and is as shown in Figure 5, the zone that the arrow in the top of cavity 170 is indicated; Another part is: the space between speaker base 160 and the mobile phone back cover 120, this segment space are the passage in sound chamber behind the loud speaker, in Fig. 5, shown in the arrow in the bottom of cavity 170.Sound chamber passage and sound chamber, back passage spread out of through penetrable sound hole 180 and 190 sound that send in the preceding sound chamber of loud speaker and sound chamber, back in the past respectively.
Be communicated in the back sound chamber passage of loud speaker for the sound that makes sound chamber behind the loud speaker can see through said sound panel 162, on said sound panel, establish a through hole 163 at least, as shown in Figure 6.And end face and bottom surface at said division board 162 have been established sealing ring 164 respectively, and the sound chamber, front and back of loud speaker is sealed respectively and before and after the main frame and between the main frame back cover, have reached desirable audio.
For the hermetically-sealed construction that makes portable terminal further reaches desirable sealing effectiveness, portable terminal of the present invention is equipped with seal 165 in the gap between said speaker base 160 and main frame fore shell 110, main frame back cover 120 and motherboard 140.Said seal 165 is further opened the preceding sound chamber passage of loud speaker with sound chamber, back channel separation.
The seal that adopts in the present embodiment is a rubber, its objective is, also replaces employed in the past foam with rubber as seal, reduces the material cost of product.The present invention realizes loud speaker and main frame fore shell, main frame back cover through adopting rubber deformation, and the sealing between the motherboard.And the sealing effectiveness of rubber is more than the good sealing effect of foam, and on the market price of rubber also far below the price of foam, thereby greatly reduce the cost of product.
In sum; Portable terminal provided by the invention; Adopted to be arranged on loud speaker and speaker base in the motherboard of portable terminal and the cavity that the main frame back cover centers on, made the compact conformation of portable terminal, realized that portable terminal is compact; Also adopt rubber as the seal of isolating sound chamber and sound chamber, back passage before the loud speaker simultaneously, greatly reduced production cost of products.
It is understandable that, concerning those of ordinary skills, can be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, and all these changes or replacement all should belong to the protection range of the appended claim of the present invention.
