Fig. 1 and Fig. 2 are please referred to, the first embodiment of the utility model proposes a kind of monomer, including front cover 1 and lower case 2.

The lower case 2 is equipped with the first holding tank 4, and the front cover 1 is arranged in first holding tank 4, before described It is equipped with the second holding tank 11 towards the lower case 2 on lid 1, is equipped with vibrating diaphragm 3 in second holding tank 11, the vibrating diaphragm 3 Edge is attached on the edge of second holding tank 11, and the edge that the front cover 1 is corresponded in the lower case 2 is equipped with ultrasound lines 12, the front cover 1 is contacted with the ultrasound lines 12, and the ultrasound lines 12 can be melted through ultrasonic device, ultrasound lines 12 and institute The melting connection of front cover 1 is stated, the region being located at other than first holding tank 4 in the lower case 2 is equipped with mounting post 26 and installation Slot 27, the mounting post 26 and the mounting groove 27 are used to monomer being mounted on other component, and the side of the lower case 2 is set There is sound mouth 21, the sound mouth 21 is connected to first holding tank 4.

The advantage of the utility model is, can in advance fasten front cover 1 and lower case 2, need to will only surpass by ultrasonic device Sound ray 12 melts the fixation that front cover 1 and lower case 2 can be realized, and simplifies production process, and molten liquid is more compared with glue curing Fastly, the production time is shortened；And vibrating diaphragm 3 is located in front cover, will not be influenced completely by 12 molten liquid of ultrasound lines.

Specifically, being equipped with positioning ring 12 in second holding tank 11, the positioning ring 12 is used to fix the vibrating diaphragm 3, Positioning ring 12 can be in the second holding tank 11, and withstands the edge of vibrating diaphragm 3, and the more existing setting of vibrating diaphragm 3 is in front cover 1 under Installation strength between shell 2 is stronger.

Preferably, the top of the ultrasound lines 12 is planar structure, when which can prevent front cover 1 and lower case 2 from fastening Ultrasound lines 12 generate damage to front cover 1.

Specifically, the section of the ultrasound lines 12 is right-angled trapezium, and right-angle side is the side far from first holding tank 4 Wall.

It should be noted that when ultrasound lines 12 are melted through ultrasonic device, due to holding close to first for ultrasound lines 12 Receive slot 4 part it is more, more molten liquid can be generated, make molten liquid focus mostly in close to the first holding tank 4 side wall.

Referring to Fig. 3, in addition, being reserved with gap between the lateral wall of the front cover 1 and the inner sidewall of the lower case 2 23, the gap 23 is used to accommodate the molten liquid after the ultrasound lines 12 melt.

It is understood that since the molten liquid of ultrasound lines 12 concentrates on the side of the side wall close to the first holding tank 4, because This can be flowed when molten liquid diffusion along gap 23, and the lateral face of the first holding tank 4 and longitudinal surface have melting at this time Liquid improves bond strength.

Further, the side wall of the lower case 2 is equipped with the first groove 25, far from described the in the lower case 2 The side wall of one holding tank 4 is equipped with the second groove 24.

It should be noted that can overflow in the first holding tank 4 or flow into when the molten liquid after the melting of ultrasound lines 12 is excessive In sound mouth, the beauty and normal use of monomer are influenced, the first groove 25 and the second groove 24 can collect excessive molten liquid, prevent Only molten liquid causes adverse consequences.

In the present embodiment, the ultrasound lines 12 are continuous cyclic structure, and in other embodiments, ultrasound lines 12 can also Think intermittent cyclic structure, can also be connected as continuous structure when the structure that the melting time breaks occurs for ultrasound lines 12.

Referring to Fig. 4, preferred, the side of the mounting post 26 is equipped with stiffening plate 261, can enhance when the monomer is installed Stability.

The second embodiment of the utility model proposes a kind of electronic equipment, which includes at least the list in first embodiment Body, the electronic equipment can be any equipment that need to export sound such as loudspeaker, mobile phone, tablet computer.

In the description of this specification, reference term " one embodiment ", " some embodiments ", " example ", " specifically show The description of example " or " some examples " etc. means specific features, structure, material or spy described in conjunction with this embodiment or example Point is contained at least one embodiment or example of the utility model.In the present specification, to the schematic table of above-mentioned term Stating may not refer to the same embodiment or example.Moreover, particular features, structures, materials, or characteristics described can be It can be combined in any suitable manner in any one or more embodiment or examples.
