The first main board 400 is an auxiliary circuit board, i.e., a USB small board. Specifically, the first main board 400 is generally fixed to an edge of the middle frame 600 for connecting the USB port 200 and the speaker 100 and the like. The second main board 300 is a main circuit board, and the first main board 400 is electrically connected to the second main board 300, so that the speaker 100, the USB port 200, and other devices execute corresponding instructions under the control of the second main board 300.

In the related art, the USB port is connected to the first motherboard, and the USB port and the first motherboard are located at an edge of the middle frame. The electronic device typically includes a plurality of speakers, wherein two speakers are symmetrically disposed on opposite sides of the USB port (or the first motherboard). It can be understood that, since the two speakers adjacent to the first motherboard are far away from the second motherboard, the cost of separately electrically connecting to the second motherboard is high and the wiring is inconvenient, and therefore the two speakers adjacent to the first motherboard usually transfer signals to the second motherboard through the first motherboard. Because the two loudspeakers adjacent to the first main board are symmetrically arranged with the first main board and need to be electrically connected with the first main board respectively, on one hand, the two loudspeakers are difficult to share the design, namely, the two loudspeakers need to use two sets of dies, and the cost is higher; on the other hand, the two loudspeakers have similar structures, so that the problem of alignment error is easy to occur, and the assembly efficiency of a production line is influenced. In view of this, it is necessary to provide a new speaker.

Referring to fig. 4, 5, 6 and 7 together, fig. 6 is a perspective view of the speaker shown in fig. 4, and fig. 7 is an exploded view of the speaker shown in fig. 6. The present embodiment provides a new speaker 100, which may include, but is not limited to, a speaker body 10 and a flexible circuit board 20. The speaker body 10 may include a first fixing portion 101 and a second fixing portion 102 having the same structure, one end of the flexible circuit board 20 is connected to the first fixing portion 101 and/or the second fixing portion 102, and the other end is electrically connected to the first main board 400. Specifically, the number of the first fixing portions 101 is at least one, and the number of the second fixing portions 102 is at least one.

In this embodiment, the first fixing portion 101 and the second fixing portion 102 are symmetrically disposed along the center line L of the speaker body 10, so that the speaker 100 has an attractive structure. In other embodiments, the first fixing portion 101 and the second fixing portion 102 may be at any position of the speaker main body 10, respectively, and are not limited herein.

Specifically, the speaker body 10 may include a first side 1011 (e.g., a left side of the speaker body 10) and a second side 1012 (e.g., a right side of the speaker body 10) that are opposite to each other, the first fixing portion 101 may be located on the first side 1011 of the speaker body 10, the second fixing portion 102 is located on the second side 1012 of the speaker body 10, and the first fixing portion 101 and the second fixing portion 102 are symmetrical with respect to a center line L of the speaker body 10.

Optionally, the first main board 400 may include a first end 401 (e.g., the left end of the first main board 400) and a second end 402 (e.g., the right end of the first main board 400) opposite to each other, and the speaker 100 may be located at the first end 401 of the first main board 400 and electrically connected to the first main board 400 through the flexible circuit board 20 on the second fixing portion 102, or located at the second end 402 of the first main board 400 and electrically connected to the first main board 400 through the flexible circuit board 20 on the first fixing portion 101. It is understood that when the flexible circuit board 20 is only located at the first fixing portion 101, the speaker 100 can be fixed to the second end 402 of the first main board 400; when the flexible circuit board 20 is only located at the second fixing portion 102, the speaker 100 can be fixed at the first end 401 of the first main board 400; when the flexible circuit board 20 is located at both the first fixing portion 101 and the second fixing portion 102, the speaker 100 may be located at the first end 401 or the second end 402 of the first main board 400, i.e. the speaker 100 does not need to distinguish its location on the first main board 400. Through the above manner, no matter the speaker 100 is located at the first end 401 of the first main board 400, or located at the second end 402 of the first main board 400, the structure of the speaker main body 10 is the same, that is, the speaker main body 10 only needs one set of mold, so that the universality is strong, and the mold opening cost can be greatly reduced.

It is understood that when the flexible circuit boards 20 are located at the first fixing portion 101 and the second fixing portion 102, the speaker 100 can be located at either end of the first main board 400, i.e. there is no need to distinguish the first end 401 and the second end 402 of the first main board 400, and it is understood that this is convenient for installation and has better reliability, but one of the flexible circuit boards 20 is idle, which results in waste of materials. When the speaker 100 needs to be fixed to the first end 401 of the first main board 400, the flexible circuit board 20 can be selected to be located on the speaker 100 on the second fixing portion 102, so as to ensure the accuracy and reliability of the alignment of the speaker 100 and reduce the waste of auxiliary materials of the flexible circuit board 20. Similarly, when the speaker 100 needs to be fixed to the second end 402 of the first main board 400, the speaker 100 with the flexible circuit board 20 located at the first fixing portion 101 may be selected to ensure the positioning accuracy and reliability of the speaker 100 and reduce the waste of auxiliary materials of the flexible circuit board 20.

With reference to fig. 7, further, one end of the flexible circuit board 20 can be detachably connected to the first fixing portion 101 and/or the second fixing portion 102. Specifically, the flexible circuit board 20 is mounted on the first fixing portion 101, and the speaker 100 may be located at the second end 402 of the first main board 400; the flexible circuit board 20 is mounted on the second fixing portion 102, and the speaker 100 may be located at the first end 401 of the first main board 400; the flexible circuit board 20 is disposed on both the first fixing portion 101 and the second fixing portion 102, and the speaker 100 may be disposed at the second end 402 or the first end 401 of the first main board 400. That is, the speaker 100 can be flexibly adjusted on the first fixing portion 101 or the second fixing portion 102 according to the position of the first main board 400, so as to meet the alignment requirement of the speaker 100.

Referring to fig. 8, optionally, the speaker body 10 may be provided with a card slot 103 (specifically, a first card slot 103a and a second card slot 103b) respectively located on the first fixing portion 101 and the second fixing portion 102, and at least a portion of the flexible circuit board 20 is held in the card slot 103, so that the flexible circuit board 20 can be detachably connected to the first fixing portion 101 and/or the second fixing portion 102. In other words, the first fixing portion 101 may have a first card slot 103a, the second fixing portion 102 may have a second card slot 103b, and at least a portion of the flexible circuit board 20 may be connected to the first card slot 103a, so that the speaker 100 can be located at the second end 402 of the first main board 400. Alternatively, the first fixing portion 101 may have a first card slot 103a, the second fixing portion 102 may have a second card slot 103b, and at least a portion of the flexible circuit board 20 may be connected to the second card slot 103b, so that the speaker 100 can be located at the first end 401 of the first main board 400. Still alternatively, the first fixing portion 101 may have a first card slot 103a, the second fixing portion 102 may have a second card slot 103b, and the flexible circuit board 20 is connected to the first card slot 103a and the second card slot 103b, so that the speaker 100 can be located at any end of the first main board 400.

It is understood that when the speaker 100 needs to be disposed at the first end 401 of the first main board 400, the flexible circuit board 20 may be mounted to the second card slot 103b of the speaker 100; when it is required to dispose the speaker 100 at the second end 402 of the first main board 400, the flexible circuit board 20 may be mounted to the first card slot 103a of the speaker 100. That is, the flexible circuit board 20 can be flexibly mounted on the first card slot 103a and/or the second card slot 103b according to the position requirement of the speaker 100, so that the structure of the speaker body 10 can be commonly used no matter where the speaker 100 is located, and the electrical connection between the flexible circuit board 20 and the first main board 400 in the speaker 100 can be ensured.

The first main plate 400 is fixed to the middle frame 600, and the first main plate 400 covers at least a portion of the first ear groove 6011 of each fixing groove 601 or is disposed adjacent to the first ear groove 6011 of each fixing groove 601. The speakers 100 correspond to the fixing grooves 601 one to one. One of the first fixing portion 101 and the second fixing portion 102 is fixed in the first ear groove 6011, and the other of the first fixing portion 101 and the second fixing portion 102 is fixed in the second ear groove 6012, in other words, the first fixing portion 101 or the second fixing portion 102 in each first ear groove 6011 is connected to the flexible circuit board 20, one end of the flexible circuit board 20 is electrically connected to the sound generating unit 13, and the other end is electrically connected to the first main board 400.

Further, a fool-proof column 6013 is disposed in the second ear slot 6012, and fool-proof holes 107 corresponding to the fool-proof column 6013 are disposed on the first fixing portion 101 and the second fixing portion 102; the fool-proof pillar 6013 is clamped in the corresponding fool-proof hole 107 for fixing the speaker 100 in the corresponding fixing slot 601, that is, the flexible circuit board 20 is disposed on the first fixing portion 101 or the second fixing portion 102, and the fool-proof hole 107 of the first fixing portion 101 or the second fixing portion 102 is shielded and cannot be matched with the fool-proof pillar 6013.

When the flexible circuit board 20 of the speaker 100 is located on one of the first fixing portion 101 and the second fixing portion 102, specifically, taking the speaker 100 with the flexible circuit board 20 located on the first fixing portion 101 as an example, when the speaker 100 is located in the fixing groove 601 on the first end 401 side of the first main board 400, the first fixing portion 101 is received in the second ear groove 6012 (i.e., the flexible circuit board 20 is located in the second ear groove 6012), and the second fixing portion 102 is received in the first ear groove 6011, at this time, the flexible circuit board 20 is far away from the first main board 400, i.e., the speaker 100 cannot be mounted in the corresponding fixing groove 601. Because the fool-proof column 6013 is disposed in the second ear slot 6012, the fool-proof column 6013 is clamped in the fool-proof hole 107 of the first fixing portion 101, so that the flexible circuit board 20 in the first fixing portion 101 cannot be clamped with the first fixing portion 101 or the flexible circuit board 20 is far away from the first fixing portion 101, which is convenient for a production line worker to find an installation error in time, and improves the efficiency and reliability of the alignment of the speaker 100.

Of course, if the speaker 100 is directly located in the fixing groove 601 at the second end 402 side of the first main board 400, the first fixing portion 101 is received in the first ear groove 6011 (i.e. the flexible circuit board 20 is located in the first ear groove 6011), and the second fixing portion 102 is received in the second ear groove 6012. Since the fool-proof pillar 6013 is disposed in the second ear slot 6012, the fool-proof pillar 6013 is clamped in the fool-proof hole 107 of the second fixing portion 102, and the fool-proof pillar 6013 has no influence on the flexible circuit board 20, which indicates that the speaker 100 is accurately aligned with the fixing slot 601.

Referring to fig. 7 and 8, in another embodiment, one end of the flexible circuit board 20 of the speaker 100 is detachably connected to the first fixing portion 101 and the second fixing portion 102, respectively. Specifically, since the flexible circuit board 20 is disposed on both the first fixing portion 101 and the second fixing portion 102, no matter the speaker 100 is located in the fixing groove 601 at the first end 401 of the first main board 400 or located in the fixing groove 601 at the second end 402 of the first main board 400, one flexible circuit board 20 can be electrically connected to the first main board 400, so that alignment between the speaker 100 and the fixing groove 601 is not required to be considered, and the mounting efficiency is further improved.

Further, a fool-proof column 6013 is disposed in the second ear slot 6012, and fool-proof holes 107 corresponding to the fool-proof column 6013 are disposed on the first fixing portion 101 and the second fixing portion 102; the fool-proof columns 6013 are caught in the corresponding fool-proof holes 107 for enabling the speaker 100 to be fixed in the corresponding fixing grooves 601.

It can be understood that, when the speaker 100 is fixed in one of the fixing slots 601, since the fool-proof pillar 6013 is disposed in the second ear slot 6012, the fool-proof pillar 6013 is clamped in the fool-proof hole 107 of the first fixing portion 101 or the second fixing portion 102, so that the flexible circuit board 20 on the corresponding first fixing portion 101 or the corresponding second fixing portion 102 can be automatically separated, thereby reducing consumption of auxiliary materials of the flexible circuit board 20, and further saving production cost on the basis of improving production efficiency.

In a specific embodiment, the middle frame 600 includes two fixing slots 601, and the two fixing slots 601 are respectively located at two sides of the first main board 400; the electronic device 1000 includes two speakers 100, and each speaker 100 is fixed in any one of the fixing grooves 601. Specifically, the middle frame 600 includes a first fixing groove 601 and a second fixing groove 601, the first fixing groove 601 is located at the first end 401 of the first main board 400, and the second fixing groove 601 is located at the second end 402 of the second main board 300. The two speakers 100 are respectively a first speaker 100 and a second speaker 100, wherein the flexible circuit board 20 of the first speaker 100 is at least located on the second fixing portion 102, the flexible circuit board 20 of the second speaker 100 is at least located on the first fixing portion 101, the first speaker 100 is fixed in the first fixing groove 601, and the second speaker 100 is fixed in the second fixing groove 601.

Of course, the first speaker 100 and the second speaker 100 may be customized according to the requirement. Specifically, since one end of the flexible circuit board 20 is detachably connected to the first fixing portion 101 and/or the second fixing portion 102, when the flexible circuit board 20 is connected to the second fixing portion 102, the speaker 100 is the first speaker 100, and when the flexible circuit board 20 is connected to the first fixing portion 101, the speaker 100 is the second speaker 100. That is, the user adjusts the position of the flexible circuit board 20 on the speaker body 10 as needed so that the speaker 100 can be adapted to different positions.

In another embodiment, if the flexible circuit board 20 of the first speaker 100 is respectively located on the first fixing portion 101 and the second fixing portion 102, and the flexible circuit board 20 of the second speaker 100 is respectively located on the first fixing portion 101 and the second fixing portion 102, the first speaker 100 and the first speaker 100 can be interchanged in position, so that the alignment of the speaker 100 and the fixing groove 601 does not need to be considered, and the installation efficiency is further improved.

Optionally, the middle frame 600 may have a first mounting hole 602 corresponding to the first fixing hole 105 and a second mounting hole 603 corresponding to the second fixing hole 106, and the speaker body 10 is inserted into the first fixing hole 105 and the corresponding first mounting hole 602 through a fixing member, and the fixing member is inserted into the second fixing hole 106 and the corresponding second mounting hole 603, so as to fix the speaker 100 to the middle frame 600. It is to be understood that, whether the speaker 100 is fixed to the first end 401 of the first main board 400 or the second end 402 of the first main board 400, the speaker body 10 is adapted to be connected to the middle frame 600.
