Description
Technical field
The utility model relates to small-sized digital electrical apparatus field, the structure of a kind of small-sized audio amplifier of saying so more specifically.
Background technology
Small-sized digital audio amplifier is because volume is little, and integration component is many, and many members crowd in limited little space, and influence each other is very serious, causes the decline of tonequality.Existing improving technology carries out spatial separation exactly in voice box casing, enclosure interior is separated into a plurality of spaces for using with different member, reduces phase mutual interference each other.But,, be difficult to the required minimum space of reasonable distribution different component though can be separated into a plurality of separate space because the inner space of small-sized digital audio amplifier is very limited.As the needs of other loud speakers are satisfied in the sympathetic response space of having to sacrifice woofer.
The utility model content
Technical problem to be solved in the utility model is the defective that overcomes prior art, the structure of the small-sized audio amplifier of each member usage space of reasonable distribution.
The utility model is achieved through the following technical solutions above-mentioned purpose.
The structure of the described small-sized audio amplifier of this patent, comprise the audio amplifier main body, left and right loud speaker and the woofer that is installed in the audio amplifier main body, its structure-improved is also to comprise at least two cavitys that protrude from the audio amplifier main body, be used to install left and right loud speaker, the cavity of described protrusion is not communicated with the audio amplifier main body.This patent structure-improved is to be used for the little member of spatial accommodation demand by seeking from the outside of audio amplifier main body, and the main space of audio amplifier main body is conveyed the member big to space requirement.For the member of audio amplifier, woofer is the member that needs big its effect of resonator competence exertion, and power is big, and caloric value is also big, so this patent is installed in it in main body.The big structure of other caloric values also is installed, as structures such as circuit boards in the audio amplifier main body.Because the inner space of audio amplifier main body is bigger, helps distributing of heat, so the small-sized audio amplifier of this type even can not adopt radiator.Little for power, caloric value is little and resonator is required little member, this patent adopts the cavity that protrudes on main body to hold, do not take the inner space of main body, as structures such as left and right loud speakers, and be not communicated with the audio amplifier main body by the cavity that seal approach make to be protruded, guarantee not influence each other between each sounding member.
The utility model is with respect to prior art, more reasonably at each different member designs be fit to the space of its use, the cavity that design by moulding can simply remedy protrusion is to the moulded influence that brings, even helps improving the aesthetic feeling of moulding.Through the audio amplifier internal structure of proportional space design, can further improve the tonequality of each sounding member, guarantee the heat radiation of member and avoid influencing each other between member, thereby further improve the whole structure of audio amplifier to have substantive distinguishing features and progress.

Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Structure in conjunction with a kind of small-sized audio amplifier shown in Fig. 1,2,3, the audio amplifier main body of class sphere comprises shell 1 and base 2 two parts with circular arc inwall, shell 1 bottom is provided with the opening that matches with base 2, base 2 embeds shell 1 bottom sealing opening and forms closed audio amplifier main body, shell 1 top has two cavitys 11,12 that protrude from audio amplifier main body 1, and the cavity 11,12 of described protrusion is not communicated with the audio amplifier main body.The audio amplifier main body by four supporting legs 3 with the audio amplifier body supports apart from desktop one segment distance, woofer is installed in the audio amplifier body interior, direction is isolated by graticule mesh 21 down; Left and right loud speaker is installed in the cavity 11,12 of protrusion, isolates fully with woofer.The top of audio amplifier main body also is provided with the digital interface 4 that is used to connect music player, can be connected with players such as iPhone, is used for playing back music.
Can further understand the internal structure of present embodiment in conjunction with Fig. 4 and Fig. 5, the inwall of described audio amplifier main body is circular arc, the housing and the shell 1 of described cavity 11,12 are one-body molded, shell 1 is formed by 13,14 butt joints of two shell sheets, abutment joint runs through two cavitys 11,12, and cavity 11,12 bottoms are provided with and are used for closed cavity 11,12 and shell 1 integrated diaphragm seal.Woofer 5 is installed on the bottom of audio amplifier main body, and bilateral symmetry is provided with two phase-reversing tubes 6 of straight tube shape, and phase-reversing tube 6 openings 22 are positioned at the bottom of audio amplifier main body.The cross section ovalize of phase-reversing tube 6, height is greater than the height of woofer 5.The inwall of circular arc can reduce the diffraction of sound in enclosure interior, and whole casing 1 is specialized in woofer 5 as resonator, helps reducing disturbing, and improves tonequality.Two phase-reversing tubes 6 and the design that is higher than woofer 5 meet the designs of sound and fluid mechanics, further improve the cooling effect and the bass effect of audio amplifier, adopt the plurality of stepped serrations design can reduce the desktop reflection and enter housing formation interference once more.
Present embodiment further is fixedly mounted on integration module that cooperates with shell 1 of formation on the base 2 with woofer 5 and phase-reversing tube 6, as Fig. 5, shown in Figure 6.Housing 1 opening inboard is provided with annular boss 15, and the interior diameter of annular boss 15 is less than the diameter of housing 1 opening.Base 2 outward flanges are provided with the leg 23 of projection, and the height of leg 23 is the distance of annular boss 15 to housing 1 opening.The inboard of leg 23 is provided with the bracing frame 24 that is used to support woofer 5, is provided with some through holes in the bracing frame 24 of base 2 and forms graticule mesh 21, and bracing frame 24 keeps certain distance with woofer 5 built on stilts graticule mesh 21 with base 2 bottom surfaces.Annular boss 15 forms a toroidal cavity 26 with the fit structure of leg 23 in the periphery of woofer 5, forms the structure of an air chamber, can absorb the vibrations of woofer 5, and play the effect of seal isolation.Bracing frame 24 forms a cavity 25 with woofer 5 built on stilts backs, as shown in Figure 3, has improved the air flow property of woofer 5 belows, further strengthens bass effect.The improvement of above-mentioned two structures is all in order further to improve bass effect.
