Problems solved by technology

Welding wire connection is easy to cause poor battery welding short circuit, and connector connection requires additional connector components, resulting in complicated process and increased cost
In addition, the welding wire connection is soft and does not have rigidity, and the connector connection often increases the difficulty of automatic production due to the addition of connectors, which is not conducive to the improvement of production efficiency.
In addition, since the speaker and the main board are connected by wires or connectors in the prior art, the welding of the speaker does not need to consider the influence of the metal part of the speaker on the welding during automatic production
[0004] To sum up, the existing Bluetooth headset connection technology has technical problems such as difficulty in automatic production, complex production process, and easy short circuit.
In addition, the existing bluetooth headset connection technology still has a technical blind spot that does not consider the impact of the metal part of the horn on welding in automated production and how to solve it

Embodiment 1

[0037] see figure 1 , figure 2 , image 3 , the present embodiment provides a speaker assembly, including: a speaker 10, an FPC board 11 and a battery 12;

[0038] The FPC board 11 includes a middle plate 110, and the middle plate 110 is located between the battery 12 and the horn 10; the middle plate 110 is provided with a welding position 1100; the horn 10 includes a horn body 100 and a metal part 40; the metal part 40 is arranged on the horn body 100, One side of the horn body 100 is provided with a pad 1000, the height of the pad 1000 is equal to the surface of the metal part 40 or higher than the surface of the metal part 40 and close to the surface of the middle plate 110;

[0039] The welding position 1100 and the pad 1000 are welded to fix the horn body 100 and the middle plate 110 .

[0040] It should be noted that the metal part 40 can be called a horn U-cup or a U-iron, which has a magnetic material inside and a metal material outside. The metal part 40 is a co...

Embodiment 2

[0050] see image 3 , on the basis of the first embodiment, the second embodiment further provides an FPC board.

[0051] In this embodiment, the FPC board 11 also includes a top board 19 and a first soft board 18; the reinforcement board 20 is connected under the top board 19, and the top board 19 is connected to the middle board 110 through the first soft board 18; the first soft board 18 can be bent, The top board 19 , the first soft board 18 and the middle board 110 jointly enclose the battery installation position 24 .

[0052] It should be noted that, on the one hand, the inventive contribution of this embodiment lies in: since the first flexible board 18 can be bent, the top board 19, the first flexible board 18 and the middle board 110 together form the battery installation position 24, so that the battery can be stored and installed Inside the battery mounting position 24, there is no need to install additional battery mounting parts, thereby effectively reducing the...

Embodiment 3

[0061] see Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , On the basis of any one of the above embodiments, Embodiment 3 provides a horn assembly, which includes a horn cover 101; the front cavity of the horn cover 101 has a front flange 1010, and the rear cavity of the horn cover 101 has a rear flange 1011; The horn body 100 is fitted between the front flange 1010 and the rear flange 1011 ; the horn body 100 has a lower edge step 1001 ; an injection groove 13 is formed between the lower edge step 1001 and the rear flange 1011 .

[0062] It should be noted that the horn cover 101 is used to assemble the assembly structure proposed in the first or second embodiment. For example, the assembly structure proposed in Embodiment 1 or Embodiment 2 can be assembled into the bracket 60 and then assembled into the horn cover 101 . Wherein, after the speaker cover 101 and the bracket 60 are assembled, a glue groove 70 (for example, the groove width is more ...

Abstract

The invention belongs to the technical field of earphones, and provides a loudspeaker assembly and a Bluetooth earphone, wherein the loudspeaker assembly comprises a loudspeaker, an FPC board and a battery; the FPC board comprises an intermediate plate; the intermediate plate is located between the battery and the loudspeaker; the intermediate plate is provided with a welding position. The loudspeaker comprises a loudspeaker body and a metal part; the metal part is arranged on the loudspeaker body; one side of the loudspeaker body is provided with a bonding pad; the height of the bonding pad is equal to the height of the surface of the metal part or is higher than the surface of the metal part and is close to the plate surface of the middle plate; and the welding position is welded with the bonding pad to fix the horn body and the middle plate, so that the connection of the horn body and the FPC plate can avoid the defects of short circuit and low automation degree caused by wire connection, can avoid the manufacturing defects of cost increase, complex process and low automation degree caused by connector connection, and the technical effects of efficient production and automatic production are achieved.

Description

technical field [0001] The invention belongs to the technical field of loudspeakers, in particular to a loudspeaker assembly and a bluetooth earphone. Background technique [0002] Bluetooth earphones are widely recognized by the market due to their technical features such as miniaturization and no external earphone cable. Usually, a Bluetooth headset includes a speaker, a battery, a microphone board and other components connected to the main board, so as to realize power transmission and signal communication of each component in the component. [0003] In existing bluetooth earphones, components such as speakers, batteries, and Mic that are connected to the motherboard mainly include two types of connection methods, one is connected by welding wires, and the other is connected by connectors. Welding wire connection is likely to cause poor battery welding short circuit, and connector connection requires additional connector components, resulting in complicated process and i...
