As consumer increasingly payes attention to the sound quality of electronic equipment, especially bass effect, double-tone chamber loud speaker at
For the increasingly design of mainstream in electronic equipment.The sound chamber of double-tone chamber loud speaker is divided into preceding sound chamber and rear sound chamber, and preceding sound chamber is with after
Sound chamber is completely separated；Sound chamber directly affects the audio of double-tone chamber loud speaker afterwards, theoretically, if rear sound chamber is fully sealed, and volume
Bigger, then bass effect is better；However, present electronic equipment is more and more frivolous, each component therein takes up space pole
Its is limited, and the design of rear sound chamber is caused also to be increasingly difficult to.It, can be with this application provides rear sound chamber assembly embodiment as described below
Sound cavity volume after increase makes sound sound and feels more melodious so as to improve the low frequency characteristic of sound.
Refering to fig. 1, Fig. 1 is the principle schematic of double-tone chamber loud speaker in electronic equipment.Double-tone chamber loud speaker 10 includes raising
Sound device 11 and sound chamber enclosure wall 12.
Wherein, loud speaker 11 is placed in space made of sound chamber enclosure wall 12 surrounds, and the space is divided into two skies
Between, wherein the larger space of volume is rear sound chamber 13, and wherein the space of small volume is preceding sound chamber 14, and sound chamber 13 and preceding sound afterwards
Chamber 14 is completely separated, to avoid forward and backward sound interferes counteracting and causes sound small, meanwhile, rear sound chamber 13 is as far as possible completely
Sealing, low cut is caused to avoid occurring leaking, and the part that sound chamber enclosure wall 12 corresponds to preceding sound chamber 14 offers preceding sound chamber
Go out acoustic aperture 15, in order to which the sound transmission for generating loud speaker 11 is gone out.
By taking musical sound as an example, rear sound chamber 13 mainly influences the low frequency part of musical sound, and preceding sound chamber 14 mainly influences musical sound
High frequency section；And influence of the low frequency part of musical sound to sound quality is very big, usually, low frequency wave crest more leans in frequency response curve
A left side, bass is more prominent, subjective to think that musical sound sounds more melodious.Theoretically, in design double-tone chamber loud speaker 10
Rear sound chamber 13 when, the volume of rear sound chamber 13 wants as big as possible so that low frequency wave crest is constantly moved to the left in frequency response curve, from
And constantly improve the low frequency characteristic of musical sound, so that musical sound is sounded and feels more melodious.
It is to be appreciated that when double-tone chamber loud speaker 10 is applied to electronic equipment, on the one hand, since the size of electronic equipment is
It is fixed, then being placed in double-tone chamber loud speaker 10 therein can not possibly be infinitely great, that is to say, the rear sound of double-tone chamber loud speaker 10
The volume of chamber 13 can not possibly be infinitely great, and on the other hand, electronic equipment internal needs to house various elements, for example, battery,
Processor, antenna, loud speaker etc., to realize its abundant application of function, therefore, electronic equipment internal is often very " crowded "
, it is also limited to leave the space of double-tone chamber loud speaker 10 for.
For this purpose, when designing double-tone chamber loud speaker 10, it is necessary to the confined space in electronic equipment is made full use of, with as far as possible
The volume of sound chamber 13 after ground increase, while considering and evading influence of the other elements to rear 13 leakproofness of sound chamber, it is double to improve
The sound quality of sound chamber loud speaker 10, and then improve experience effect when user uses electronic equipment in terms of sound quality.

It is the structural schematic diagram of electronic equipment embodiment provided by the present application refering to Fig. 2 to Fig. 6, Fig. 6 jointly.The present embodiment
Electronic equipment 30 can be any equipment for having sound outer playing function, such as：Mobile phone, tablet computer, personal computer
(Personal Computer, PC), laptop, mobile unit, Web TV, wearable device etc..
Electronic equipment 30 provided by the present application includes the rear sound chamber component 20 and loudspeaker group described in above-mentioned the embodiment of the present application
Part 31.
Wherein, the concrete structure of rear sound chamber component 20 is referred to the description of above-described embodiment, and details are not described herein.
In the present embodiment, the first sound chamber enclosure member 22 is equipped with sound mouth (not shown), and horn assembly 31 is located at
In first space 24, and the open butt joint of the sound mouth (not shown) of horn assembly 31 and the first sound chamber enclosure member 22,
It is gone out with the sound transmission for generating horn assembly 31, and is fully sealed around the two junction so that the first space 24 exists
It is completely separated with the preceding sound chamber (not shown) of double-tone chamber loud speaker at sound mouth, to avoid forward and backward sound interfere to
Disappear and causes sound small.
Electronic equipment 30 further includes cover board 32, and cover board 32 is covered on end face of the sealing element 27 far from substrate 21, to seal
One space 24 and second space 25, as shown in Figure 7.
Further, bridge member 26 is arranged along the gap 34 between another element 33 in cover board 32 and electronic equipment,
And sealing element 27 is further attached at end face of the bridge member 26 far from substrate 21, at gap 34 seal the first space 24 and
Second space 25.
It is to be appreciated that since 30 inner space of electronic equipment is limited, and need the arrange element accommodated and extremely more, hardly possible
The case where exempting from that overlapped interference between elements can be deposited, if rear sound chamber component 20 or its cover board 32 are interfered with another element 33,
The leakproofness of rear sound chamber component 20 may be then caused not reach requirement.
For example, by the way that the second sound chamber enclosure member 23 is arranged on 22 periphery of the first sound chamber enclosure member in above-described embodiment,
Increase the volume of rear sound chamber component 20, but also need to consider be set to 23 place space of the second sound chamber enclosure member other
Element is attached at as shown in figure 8, cover board 32 produces gap 34 with another element 33 in joining place at this time when by cover board 32
It, can be because causing there are gap 34 when end face of the sealing element 27 far from substrate 21 is to seal the first space 24 and second space 25
The leakproofness of first space 24 and second space 25 is deteriorated, as shown in Figure 9.
In the present embodiment, when bridge member 26 is used for situation as shown in Figure 9, it is connected to 34 corresponding sealing element of gap
27, to ensure the leakproofness in the first space 24 and second space 25, as shown in Figure 10.
The case where being different from the prior art, it is provided by the present application after sound chamber component include substrate and stand on the of substrate homonymy
