Description

Loud speaker

Technical field

The utility model is related to a kind of loud speaker more particularly to a kind of loud speakers for being capable of waterproof.

Background technology

With the development of science and technology, social progress, electronic product are largely popularized, and then obtain electro-acoustic element A large amount of use is arrived, in order to obtain enjoyment preferably acoustically, people are to electro-acoustic element（Such as loud speaker）Acoustical behavior It is required that it is higher and higher, meanwhile, it is also higher and higher for the waterproof performance requirement of loud speaker.

The relevant technologies loud speaker generally includes the shell of receiving magnetic circuit system and vibrational system and is covered on shell Upper cover, the vibrational system include vibrating diaphragm, and opposite vibrating diaphragm offers sound mouth on the upper lid, in order to ensure that portable electronic is set Standby fire resistance characteristic, vibrating diaphragm edge is flatly fitted between shell and upper cover by generally use glue in traditional technology, and logical Often need to be sticked far from vibrating diaphragm side on upper lid have the upper cover of waterproof double faced adhesive tape namely loud speaker by waterproof double faced adhesive tape with just It takes formula electronic equipment and pastes contact, waterproof double faced adhesive tape can pass through loud speaker upper cover and portable electronic device to avoid environmental liquids Between gap enter inside loudspeakers, ensure waterproof effect.However, traditional sound mouth opening due to upper cover is excessive, experiment In the process, air pressure and water can be quickly entered in vibrating diaphragm by sound mouth, it is impossible to meet the tightened up waterproof of electro-acoustic element It is required that.

Therefore, it is really necessary to propose a kind of new loud speaker to overcome the above problem.

Utility model content

The purpose of the utility model is to overcome above-mentioned deficiency of the prior art, providing a kind of can meet tightened up waterproof It is required that loud speaker.

To achieve these goals, the utility model provides a kind of loud speaker, including shell, the magnetic being contained in shell Road system and vibrational system and lid connect upper cover on the shell, and the vibrational system includes vibrating diaphragm, and the vibrating diaphragm is included in being located at The top dome portion of heart position and positioned at the ring portion of marginal position, the periphery in the ring portion is folded between upper cover and shell, institute State and a sound mouth opposite with top dome portion offered in the middle part of upper cover, the upper cover be sticked on the upper surface far from vibrating diaphragm side have it is anti- The network of rivers is padded, and the waterproof gauze pad lid is located on sound mouth.

As a further improvement, upper surface of the upper cover far from vibrating diaphragm side in sound mouth periphery be recessed with downwards with The limiting slot that waterproof gauze pad outer peripheral shape and size are adapted, the size of the waterproof gauze pad are more than the ruler of upper cover sound mouth Very little, the periphery limiting of the waterproof gauze pad is attached in limiting slot.

As a further improvement, the waterproof gauze pad is sound wire side.

As a further improvement, the size of the upper cover sound mouth is less than the size in vibrating diaphragm top dome portion.

As a further improvement, being sticked on the periphery of the upper cap upper surface has waterproof double faced adhesive tape, the waterproof gauze pad Among waterproof double faced adhesive tape.

As a further improvement, the periphery in the vibrating diaphragm ring portion is with using glue Nian Jie between upper cover and shell.

In conclusion the utility model loud speaker has slowed down the external world by the waterproof gauze pad that is sticked at the sound mouth of upper cover Air pressure and flow enter the speed in vibrating diaphragm face, so as to effectively enhance waterproof effect, can meet tightened up waterproof requirement.

Description of the drawings

Fig. 2 is the part isometric exploded view of loud speaker shown in Fig. 1.

Fig. 3 is the sectional view of loud speaker provided by the utility model.

Specific embodiment

For the technology contents of the utility model, construction feature, the objects and the effects are described in detail, below in conjunction with implementation Mode simultaneously coordinates attached drawing to be explained in detail.

It please refers to Fig.1, Fig. 2 and Fig. 3, the utility model provides a kind of loud speaker 100, is suitble to be installed in portable electronic and sets In standby, it is connected on including shell 10, the magnetic circuit system being contained in shell 10 20 and vibrational system 30 and lid upper on shell 10 Lid 40, vibrational system 30 include vibrating diaphragm 31, and vibrating diaphragm 31 is included positioned at the top dome portion 311 of center and the folding positioned at marginal position Ring portion 312, the periphery in ring portion 312 are folded between upper cover 40 and shell 10, and 40 middle part of upper cover offers one and top dome portion 311 Opposite sound mouth 41, upper cover 40 is sticked on the upper surface far from 31 side of vibrating diaphragm waterproof gauze pad 50, and the lid of waterproof gauze pad 50 is set On sound mouth 41, ambient pressure is effectively slowed down with this and flow enters the speed in 31 face of vibrating diaphragm, so as to effectively enhance waterproof Effect.Wherein, the waterproof gauze pad 50 is sound wire side, while fire resistance characteristic is ensured, does not influence going out for loud speaker 100 Audio fruit.

More preferably, upper surface of the upper cover 40 far from 31 side of vibrating diaphragm is recessed with downwards and waterproof gauze pad in 41 periphery of sound mouth The limiting slot 42 that 50 outer peripheral shapes and size are adapted, the size of waterproof gauze pad 50 are more than the size of 40 sound mouth 41 of upper cover, The periphery limiting of waterproof gauze pad 50 is attached in limiting slot 42, so that it is guaranteed that the accurate installing fitting of waterproof gauze pad 50.

More preferably, the size of 40 sound mouth 41 of upper cover is less than the size in 31 top dome portion 311 of vibrating diaphragm, by by 41 ruler of sound mouth It is very little to change small, it can further slow down ambient pressure and flow enters the speed in 31 face of vibrating diaphragm, so as to further enhance waterproof effect.

In the utility model, being sticked on the periphery of 40 upper surface of upper cover has waterproof double faced adhesive tape 60, and waterproof gauze pad 50 is located at Among waterproof double faced adhesive tape 60, waterproof double faced adhesive tape 60 is used to contact with portable electronic device stickup, so as to prevent water from upper cover 40 Gap between portable electronic device is flowed into inside loud speaker 100, and the periphery in 31 ring portion 312 of vibrating diaphragm and upper cover 40 and It is bonded between shell 10 using glue, gap of the water between upper cover 40 and shell 10 is further prevented to flow into inside loud speaker 100.

Added in the upper cover 40 of the utility model loud speaker 100 40 sound mouth 41 of waterproof gauze pad 50 and upper cover size change it is small Will not change the design of magnetic circuit system 20, vibrational system 30 and shell 10, and loud speaker 100 assembling and operation principle be normal Rule, therefore do not provide detailed description herein.

In conclusion the utility model loud speaker 100 is subtracted by the waterproof gauze pad 50 that is sticked at the sound mouth 41 of upper cover 40 Slow ambient pressure and flow enter the speed in 31 face of vibrating diaphragm, so as to effectively enhance waterproof effect, can meet tightened up waterproof It is required that.

There is described herein the preferred embodiments of the utility model, are used to implement including known to utility model people The optimal mode of the utility model.It should be understood that shown embodiment is only exemplary, it is not construed as limiting this practicality newly The range of type, therefore be similarly contained in the equivalent structure variation carried out by the utility model specification and accompanying drawing content such as In the scope of the utility model.
