Description

A kind of loudspeaker enclosure

[technical field]

The utility model relates to loudspeaker fields, and in particular to a kind of loudspeaker enclosure.

[background technique]

Existing loudspeaker enclosure be by sealant by pronounce monomer 1 be glued in upper cover 2 in the way of carry out waterproof, specifically Referring to Fig. 6 to Fig. 9 in attached drawing, it is equipped with supporting beam 300 close to the position of sound channel 4 in upper cover 2, the part for the monomer 1 that pronounces Edge is glued with the supporting beam 300, thus realize waterproof herein, but supporting beam 300 is located at accommodating chamber 100 and out sound Between channel 4, barrier effect has been played to sound, has affected the performance of loudspeaker, and on the monomer 1 that pronounces not with supporting beam 300 The side of splicing still has gap 200, it cannot be guaranteed that the waterproofness of loudspeaker.

[utility model content]

The purpose of this utility model is to provide a kind of loudspeaker enclosures, can either guarantee waterproofness, and can be avoided pair Sound plays barrier effect so that influencing loudspeaker enclosure performance.

The technical solution of the utility model is as follows: a kind of loudspeaker enclosure, including pronunciation monomer, upper cover, with the upper cover phase The lower cover of cooperation forms accommodating chamber between upper cover and lower cover, and the pronunciation monomer is placed in the accommodating chamber, is provided on the upper lid The sound channel being connected with the accommodating chamber has the remote passway for being opened in cover outer wall on sound channel and close to accommodating chamber Nearly passway, the inner wall of the upper cover, which is equipped with, passes through the splicing table top that sealant is mutually glued, loudspeaker with pronunciation monomer edge Case further includes having one piece of support plate, and support plate has close end and distal portion, and close end is connect with pronunciation monomer outer wall, distal portion Positioned at the lower section of nearly passway, the side wall for being glued table top is mutually glued by sealant with table top is glued above support plate.

As preferred structure, support plate is structure as a whole with pronunciation monomer, and support plate is from the outer wall of pronunciation monomer to extension It stretches, the side outer wall of support plate forms a part of the hole wall of the sound channel.

As preferred structure, it is glued table top and includes the first splicing face being mutually glued with pronunciation monomer and be mutually glued with support plate Second be glued face, the part on the second splicing face close to nearly passway is located at the lower section of nearly passway.

As preferred structure, remote passway is lower than nearly passway, and the close end is higher than distal portion.

As an improvement, the outer rim for being glued table top is equipped with the baffle to lower cover direction protrusion.

The utility model has the beneficial effects that: support plate have close end and distal portion, close end and pronunciation monomer outside Wall is tightly connected, and distal site is in the lower section of nearly passway, because in this case distal site is supported in the lower section of nearly passway Plate is not between accommodating chamber and sound channel, causes to have played barrier effect to sound, affects the performance of loudspeaker；And And since close end and pronunciation monomer outer wall are tightly connected, in this case there would not be again sky between pronunciation monomer and upper cover Gap further ensures waterproofness herein.

[specific embodiment]

The utility model is described in further detail with embodiment with reference to the accompanying drawing.

Referring to figs. 1 to Fig. 5, a kind of loudspeaker enclosure, including the monomer 1, upper cover 2, the lower cover matched with the upper cover 2 of pronouncing 3, accommodating chamber 100 is formed between upper cover 2 and lower cover 3, upper cover 2 is in top position, below-mentioned opposite position with respect to lower cover 3 It sets as reference, in Fig. 3, upper cover 2 and lower cover 3 are in roll-over condition.

The pronunciation monomer 1 is placed in the accommodating chamber 100.The monomer 1 that pronounces is the pronunciation device for generating sound.

It is provided with the sound channel 4 being connected with the accommodating chamber 100 in the upper cover 2, has on sound channel 4 and is opened in The remote passway 41 of 2 outer wall of lid and nearly passway 42 close to accommodating chamber 100, the sound of loudspeaker is from nearly 42 Xiang Yuantong of passway It propagates at road junction 41.

The inner wall of the upper cover 2, which is equipped with, passes through the splicing table top 5 that sealant is mutually glued with pronunciation 1 edge of monomer, is glued platform Pronunciation monomer 1 is glued thereon by face 5 for breaking sealant, and the splicing table top 5 of closure can guarantee to be glued table top 5 and pronunciation The everywhere contact position of monomer 1 is sealed, and is prevented water from penetrating into, be ensure that waterproofness.

Loudspeaker enclosure further includes having one piece of support plate 6, support plate 6 have close end 61 and distal portion 62, close end 61 with 1 outer wall of monomer that pronounces is tightly connected, and distal portion 62 is located at the lower section of nearly passway 42, and support plate 6 is above to the side for being glued table top 5 Wall is glued by sealant with 5 phase of table top is glued.

Because the close end 61 of support plate 6 is connect with pronunciation 1 outer wall of monomer, this sealed connection, which can be all, prevents water In this case the sealed connection measure of infiltration would not have again gap 200 between pronunciation monomer 1 and upper cover 2, ensure that herein Waterproofness, in the present embodiment, using support plate 6 and pronunciation monomer 1 be structure as a whole, support plate 6 is by pronunciation monomer 1 The outwardly extending structure of outer wall, the side outer wall of support plate 6 forms a part of the hole wall of the sound channel 4, integrated Structure ensures that waterproofness.

Again because distal portion 62 is located at the lower section of nearly passway 42, support plate 6 above passes through the side wall for being glued table top 5 close Sealing is glued with 5 phase of table top is glued, and such words support plate 6 would not be located at accommodating chamber as the supporting beam 300 in Fig. 1 Between 100 and sound channel 4, cause to have played barrier effect to sound, affects the performance of loudspeaker.

In the present embodiment, referring in particular to Fig. 3 and Fig. 5, it is glued the specific structure of table top 5 are as follows: being glued table top 5 includes and hair 1 phase of sound monomer be glued first be glued face 51 and with 6 phase of support plate be glued second be glued face 52, second be glued face 52 on it is close The part of nearly passway 42 is located at the lower section of nearly passway 42, and the lower section that the second splicing face 52 is located at nearly passway 42 provides one Kind distal portion 62 is located at the specific embodiment of the lower section of nearly passway 42, because the side wall of support plate 6 is and the second splicing face 52 phases are glued, and the lower section that the second splicing face 52 is located at nearly passway 42 just illustrates that distal portion 62 is located under nearly passway 42 Side.

In the present embodiment, referring in particular to Fig. 2, the specific set-up mode of sound channel 4 and support plate 6 may is that remote logical Road junction 41 be lower than nearly passway 42, the close end 61 be higher than distal portion 62, this setup be formed by sound channel 4 at Shape is gradually tilted upward, water can be better protected from and flowed from remote passway 41 to nearly passway 42 so that into loudspeaker enclosure In.

It is glued the outer rim of table top 5 equipped with the baffle 7 to 3 direction of lower cover protrusion, pronunciation monomer 1 can entirely be embedded in baffle 7 Among the space surrounded, in this case, other than sealant is to the fixed function of pronunciation monomer 1, baffle 7 also plays anti- Only to the fixed function of pronunciation monomer 1.

Above-described is only the embodiments of the present invention, it should be noted here that for the ordinary skill of this field For personnel, without departing from the concept of the present invention, improvement can also be made, but these belong to it is practical Novel protection scope.
