Embodiment
Specific embodiment below in conjunction with the description of drawings utility model:
Mainboard area based on the portable terminal of disconnected plate design is less, cause that the sound cavity volume is little, the problem of lower tone, the utility model proposes a kind of speaker cavity, can be in the less situation of mainboard area, do not change existing portable terminal hardware arrangement, enlarge the volume of speaker cavity as far as possible, to guarantee tonequality, improve user experience.
As shown in Figure 5, speaker cavity is enclosed by mainboard 1, mainboard adjacent component 3, seal and casing (not shown) and forms.Wherein, seal is sealing foam 2, and sealing foam 2 is positioned on mainboard 1 and the mainboard adjacent component 3, and casing is fastened on the sealing foam 2.Because have the gap between mainboard 1 and the mainboard adjacent component 3, in order to guarantee the sealing in sound chamber, there is barrier flaps 8 in the gap in the sound chamber between mainboard 1 and the mainboard adjacent component 3.Thereby mainboard 1, mainboard adjacent component 3, barrier flaps 8, sealing foam 2 and casing form the sound cavity space of sealing.Compare and can find out by Fig. 2 and Fig. 5, the zone that sealing foam 2 encloses enlarges markedly, thereby the volume in sound chamber also increases thereupon.
Because existing terminal inner, be generally display/panel bracket 3 with the mainboard adjacent component, the below 3 is specifically described speaker cavity as example take the mainboard adjacent component as display/panel bracket.
Shown in Fig. 6-7, the sound chamber is enclosed and is formed by mainboard 1, display/panel bracket 3, seal and the casing (not shown) adjacent with mainboard 1, and wherein, seal is sealing foam 2, sealing foam 2 is positioned on the back side 3 of mainboard 1, display/panel bracket, and casing is fastened on the sealing foam 2.The back side of display/panel bracket 3 offers battery compartment 4, is used for holding battery 5, and the front of display/panel bracket 3 is used for supporting the installation display screen.In order to guarantee that battery 5 takes out the aesthetic property of rear battery compartment 4, generally can be equipped with cover plate 6 below battery compartment 4 bottom battery 5.Owing to have the gap between mainboard 1 and the display/panel bracket 3, in order to guarantee the sealing in sound chamber, cover plate 6 is extended on the mainboard 1, barrier flaps 8 is the extension 61 of cover plate 6.Thereby the extension 61 of mainboard 1, display/panel bracket 3, cover plate 6, sealing foam 2 and casing form the sound cavity space of sealing.
By the comparison of Fig. 3 and Fig. 8, can find out the structural change of cover plate 6, cover plate 6 still is installed in the battery compartment 4 with original mounting means, and the extension 61 of cover plate 6 extends on the mainboard 1, and pastes on mainboard 1, can install.Adopt the extension 61 of cover plate 6 as barrier flaps, not only can avoid increasing extra parts, and do not need to consider the problem of extension 61 with the mounting means of mainboard 1 of cover plate 6.
By the comparison of Fig. 4 and Fig. 9, can find out that the area that sealing foam 2 covers improves greatly, thereby the volume of speaker cavity improves greatly, has guaranteed tonequality.
Based on the design of above-mentioned speaker cavity, the utility model has also proposed a kind of portable terminal, the speaker cavity that portable terminal comprises casing and is positioned at casing inside.As shown in Figure 5, the sound chamber of portable terminal loud speaker is enclosed by mainboard 1, mainboard adjacent component 3, seal and casing (not shown) and forms, and wherein, seal is sealing foam 2, sealing foam 2 is positioned on mainboard 1 and the mainboard adjacent component 3, and casing is fastened on the sealing foam 2.Because have the gap between mainboard 1 and the mainboard adjacent component 3, in order to guarantee the sealing in sound chamber, there is barrier flaps 8 in the gap in the sound chamber between mainboard 1 and the mainboard adjacent component 3.Thereby mainboard 1, mainboard adjacent component 3, barrier flaps 8, sealing foam 2 and casing form the sound cavity space of sealing.Compare and can find out by Fig. 2 and Fig. 5, the zone that sealing foam 2 encloses enlarges markedly, thereby the volume in sound chamber also increases thereupon.
Because existing portable terminal, for example the inside of mobile phone is generally display/panel bracket 3 with the mainboard adjacent component, and the below 3 is specifically described as the speaker cavity of example to mobile phone take the mainboard adjacent component as display/panel bracket.
The sound chamber is enclosed and is formed by mainboard 1, display/panel bracket 3, seal and the casing (not shown) adjacent with mainboard 1, wherein, seal is sealing foam 2, and sealing foam 2 is positioned on the back side 3 of mainboard 1 and display/panel bracket, and casing is fastened on the sealing foam 2.The back side of display/panel bracket 3 offers battery compartment 4, is used for holding battery 5, and the front of display/panel bracket 3 is used for supporting the installation display screen.In order to guarantee that battery 5 takes out the aesthetic property of rear battery compartment 4, generally can be equipped with cover plate 6 below battery compartment 4 bottom battery 5.Owing to have the gap between mainboard 1 and the display/panel bracket 3, in order to guarantee the sealing in sound chamber, cover plate 6 is extended on the mainboard 1, barrier flaps 8 is the extension 61 of cover plate 6.Thereby the extension 61 of mainboard 1, display/panel bracket 3, cover plate 6, sealing foam 2 and casing form the sound cavity space of sealing.
By the comparison of Fig. 3 and Fig. 8, can find out the structural change of cover plate 6, cover plate 6 still is installed in the battery compartment 4 with original mounting means, and the extension 61 of cover plate 6 extends on the mainboard 1, and pastes on mainboard 1, can install.Adopt the extension 61 of cover plate 6 as barrier flaps, not only can avoid increasing extra parts, and do not need to consider the problem of extension 61 with the mounting means of mainboard 1 of cover plate 6.
By the comparison of Fig. 4 and Fig. 9, can find out that the area that sealing foam 2 covers improves greatly, thereby the volume of speaker cavity improves greatly, has guaranteed tonequality.
It should be noted that at last: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
