Description

A kind of loudspeaker

[technical field]

The utility model relates to energy transducer technical field more particularly to a kind of loudspeakers.

[background technique]

Loudspeaker is commonly used for the acoustic element in electronic equipment, is a kind of energy converter for electric signal being changed into acoustical signal Part.

In current loudspeaker, there is step at the boiling hot point of the corner of front cover upper end four, and is equipped with installation at step When being assembled, the mounting hole on pillar and front cover being arranged by four edges in frame upper end is matched for hole, front cover and frame Connection is closed, front cover is enable to be installed in frame.However, needing when the loudspeaker monomer to be installed on shell by front cover Upper end periphery gluing foamed cotton ring when, due to the step of front cover upper end surrounding, the upper end border of foamed cotton ring and front cover cannot be formed Effectively sealing, and when the angle R of the inner ring of foamed cotton ring is smaller, effectively sealing or effectively sealing cannot be formed to the step of front cover Area very little causes the leakproofness of the four corners of foam circle and front cover bad, bad so as to cause complete machine sealing effect.

[utility model content]

The purpose of this utility model is to provide a kind of loudspeakers, it is intended to which the front cover for solving loudspeaker in the prior art is logical When crossing foamed cotton ring and shell gluing, the bad problem of property is imitated in foam circle and glued the sealing of front cover.

The technical solution of the utility model is as follows: providing a kind of loudspeaker comprising frame and is installed in the frame Front cover, the front cover include far from the frame upper surface and close to the frame lower surface, the front cover it is upper Surface is planar structure, and the lower surface surrounding of the front cover offers blind hole, frame upper end surrounding be provided with it is described blind The corresponding guide post in hole site, after the front cover is installed in the frame, the guide post is inserted in the blind hole, described The depth that guide post is inserted into the blind hole is less than or equal to the depth of the blind hole.

Further, the front cover is in cuboid, and four edges of the front cover lower end offer the blind hole.

Further, the cross section of the blind hole is circle, and the guide post is cylinder.

Further, the upper end of the frame has step, and the guide post is set on the step, when the front cover with When the frame is mutually glued by colloid, the upper end of the guide post is inserted in the blind hole, the lower surface of the front cover with The colloid is filled between the step surface.

The utility model has the beneficial effects that: the utility model is by being arranged to planar structure for the upper surface of front cover, The step structure for eliminating traditional preceding cap upper surface surrounding cooperates the guide post in the blind hole and frame of front cover lower surface surrounding When connection, guide post is inserted in blind hole.After frame and front cover are assembled into monomer, the front cover on monomer pass through glued foamed cotton ring with When cage connection seals, foamed cotton ring can be enable all to fit on the upper surface of front cover, guarantee front cover surrounding and foamed cotton ring Good sealing effect is formed, to improve the sealing effect of complete machine.

[specific embodiment]

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

It as shown in Figure 1 to Figure 3, is a kind of loudspeaker provided by the embodiment of the utility model, which includes 1 He of frame The front cover 2 being installed in frame 1, front cover 2 include the upper surface far from frame 1 and the lower surface close to frame 1, and front cover 2 upper surface is planar structure, and the lower surface surrounding of front cover 2 offers blind hole 20, and 1 upper end surrounding of frame is provided with and blind hole 20 The corresponding guide post 10 in position, after front cover 2 is installed in frame 1, guide post 10 is inserted in blind hole 20, and guide post 10 is inserted into blind hole 20 depth is less than or equal to the depth of blind hole 20.

In the present embodiment, front cover 2 is in cuboid, and four edges of 2 lower end of front cover offer blind hole 20.The blind hole 20 cross section is circle, and guide post 10 is cylinder, and front cover 2 and frame 1 is made to form stable mating connection.In other embodiments In, the shape and blind hole and the shape of guide post of front cover 2 and frame 1 are designed according to the structural improvement of actual product.

In above-described embodiment, please referring collectively to shown in Fig. 4 to Fig. 7, the upper end of frame 1 has step 11, and guide post 10 is arranged In on step 11.When front cover 2 is installed in frame 1, there is gap, so that preceding between 11 face of lower surface and step of front cover 2 When mutually glued by colloid 3 between lid 2 and frame 1, the upper end of guide post 10 is inserted in blind hole 20, the lower surface of front cover 2 with Gap filling colloid 3 between 11 face of step, so that being formed between front cover 2 and frame 1 after gluing assembles progress gluing smooth Gluing guarantees that front cover 2 and frame 1 form more stable sealed connection.

In conclusion the utility model eliminates traditional front cover by the way that the upper surface of front cover 2 is arranged to planar structure The blind hole 20 of 2 lower surface surrounding of front cover is cooperatively connected, to basin by the step structure of 2 upper surface surroundings with the guide post 10 in frame 1 Frame 1 is fixed on the positioning.After frame 1 and front cover 2 are assembled into monomer, the front cover 2 on monomer passes through glued foamed cotton ring and shell When connection sealing, foamed cotton ring can be enable all to fit on the upper surface of front cover 2, form plane fitting, guarantee front cover 2 four Angle and foamed cotton ring form good sealing effect, to improve the sealing effect of complete machine.

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.
