Description

A kind of EVA speaker

Technical field

The utility model relates to speaker technology fields, and in particular to a kind of EVA speaker.

Background technique

Speaker refers to a kind of equipment that audio signal can be transformed to sound.Popular saying just refers to speaker host cabinet or low Power amplifier is carried in sound receiver body, audio signal is amplified, sound is played back out by speaker itself after handling, make its sound The change of tune is big.

The Chinese patent literature of Publication No. CN1189663A discloses a kind of concrete loudspeaker box, and the concrete of cabinet is It is made of cement, sand, stone, mix agent, additive and skeleton, and is formed by mold integral cast, avoid wooden sound The disadvantages of case sound quality is impure, manufacturing cost is high, its advantage is that it has the acoustics of high-fidelity, manufacturing cost is low, can scale Metaplasia produces.

The Chinese patent literature of Publication No. CN202514036U discloses a kind of Novel sound box, including casing of loudspeaker box A, speaker Shell B, casing of loudspeaker box C, and casing of loudspeaker box A, casing of loudspeaker box B, the loudspeaker in casing of loudspeaker box C are set, and are arranged outside speaker Shell A, casing of loudspeaker box B, the speaker lid on casing of loudspeaker box C, and the conducting wire of connection casing of loudspeaker box A.Since the Novel sound box is by speaker Shell A, casing of loudspeaker box B, casing of loudspeaker box C are connected with each other from three different directions, form a speaker entirety, entire novel Speaker integrally seems very harmonious also very exquisite, no matter how to put, and broadcast effect is all fine, can experience the succinct of it Beauty, structure is simple, and appearance is exquisite beautiful, and broadcast effect is good.

The Chinese patent literature of Publication No. CN101472216A discloses a kind of speaker of windbell type, including speaker and power supply Line, tone frequency channel wire, it is characterised in that its bracket is a branch of metal sound column 3 dissipated downwards, and it is small to be connected to several on sound column Speaker 2, small speaker 2 is in windbell shape, and one is main sound box 2 in small speaker 2, and main sound box 2 is equipped with infrared remote-control device, power supply Line penetrates main sound box inside metal sound column 3；Tone frequency channel wire passes through metal sound column 3 and is connected respectively with several secondary speakers 2.The sound Case can be hung on roof center, and sound seems to come from aerial band, and old-fashioned and inflexible speaker is made to have innervation.

Utility model content

The purpose of this utility model is to provide a kind of EVA speaker, EVA speaker sound quality provided by the utility model is fine and smooth, It is mellow and full and elastic.

To achieve the above object, the utility model provides a kind of EVA speaker, the speaker include porous shell, power board, Loudspeaker and power supply, the power board and power supply are set in the porous shell, and the loudspeaker are embedded in the porous shell On side wall, the loudspeaker are electrically connected with power board, and the power supply is electrically connected with power board, and the material of the porous shell is EVA Foam.

Optionally, the porous shell and power board, loudspeaker and power supply are formed by space ties filled with porous filling Structure, the material of the porous interstitital texture are eva foam.

Optionally, the porous shell is in addition to being provided with porous metal mesh on the inside of the side of loudspeaker.

Optionally, metal aluminum sheet is provided on the inside of the loudspeaker opposite side of the porous shell.

Optionally, sucker and/or velcro are stained on the outside of the porous shell.

The utility model has the following advantages that：

The speaker of the utility model can make sound quality fine and smooth, mellow and full and elastic using porous shell, and be not necessarily to noise reduction or Person is added acoustical cotton, and being capable of waterproof, moisture-proof, anti-aging and recyclable.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of specific embodiment of EVA speaker provided by the utility model.

Fig. 2 is a kind of structural schematic diagram of specific embodiment of porous interstitital texture provided by the utility model.

Fig. 3 is a kind of structural schematic diagram of specific embodiment of porous metal mesh provided by the utility model.

Fig. 4 is a kind of structural schematic diagram of specific embodiment of metal aluminum sheet provided by the utility model.

Specific embodiment

The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.

As shown in Figure 1, the utility model provides a kind of EVA speaker, the speaker includes porous shell 1, power board 2, loudspeaker 3 and power supply 4, the power board 2 and power supply 4 be set in the porous shell 1, the loudspeaker 3 are embedded in described porous outer On the side wall of shell 1, the loudspeaker 3 are electrically connected with power board 2, and the power supply 4 is electrically connected with the power board 2, described porous outer The material of shell 1 is eva foam.EVA is ethylene-vinyl acetate copolymer, and eva foam has porous structure, will have porous Harmful standing wave can be absorbed as the shell of speaker in the eva foam of structure, improves sound quality, and sound quality is fine and smooth, mellow and full and elastic, and And eva foam is easy to cut, aperture, avoids using security risk brought by excessive machinery production, without noise reduction or Add acoustical cotton mistake, easy-maintaining, waterproof, moisture-proof, anti-aging is also recyclable, light-weight, simple and remarkable, low-carbon environment-friendly.

Porous shell can be as shown in Figure 1 square hollow, including five faces and dismountable 6th face being bonded together, The aperture for exposing loudspeaker is provided on 6th face.The speaker of the utility model other components such as power amplifier other than shell The components such as plate, loudspeaker and power supply can be using conventional and existing, such as the model of power board can be ALM1875, and loudspeaker can Think French Audi this, power supply can reequip after can also being removed existing casing of loudspeaker box for USB power source etc..

Since eva foam is softer, have to improve the stability of remaining part placement and further increase noise reduction and absorption Evil standing wave, as shown in Fig. 2, the porous shell 1 is formed by space and can be filled with power board 2, loudspeaker 3 and power supply 4 The material of porous interstitital texture 5, the porous interstitital texture can be eva foam, which can be embedded in remaining Porous interstitital texture 5 in component, such as Fig. 2 has the rear portion for being put into power board and power supply fluting and is put into the rotary table of loudspeaker Shape aperture.

The speaker of common metal has the function of shielding electric wave, and the broadcasting of speaker is influenced when can prevent from making a phone call, due to The casing of loudspeaker box of the utility model is prepared using eva foam, and therefore, as shown in Fig. 3, the porous shell 1 is in addition to loudspeaker 3 Porous metal mesh 6 can be set on the inside of side, so as to effectively shield electric wave, improved the stability that speaker plays.

Further, eva foam thermal insulation property is preferable, therefore, in order to improve the radiating rate of power board and power supply, such as schemes Shown in 4, metal aluminum sheet 7 can be set on the inside of 3 opposite side of loudspeaker of the porous shell 1, which can be with Power board and power supply fit, thus quick conductive and heat dissipation.

Since eva foam is lighter, to be easy vibration as vehicle audio in automobile, and it is placed on desk and is easy It falls, therefore, the outside of the porous shell 1 is stained with sucker and/or velcro, so that whole sound equipment be made to be capable of fixing in the car Or on desk, preferably sucker and velcro is embedded in porous shell.

Although above having made detailed description to the utility model with generality explanation and specific embodiment, On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art 's.Therefore, these modifications or improvements on the basis of without departing from the spirit of the present invention, belong to the utility model and want Seek the range of protection.
