[0016] Next, with reference to the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, any combination can be formed among the following described embodiments or technical features to form a new embodiment.

[0017] Refer to Figures 1 - 4 , an embodiment of the present invention provides a speaker assembly structure and a speaker using the assembly structure.

[0018] The speaker assembly structure of the embodiment of the present invention includes a speaker frame 1, a PCB board 2, a power input terminal 3 for connecting to an external power supply, an audio input terminal 4 for connecting to an external signal source, and an audio output terminal 5 for connecting to a speaker driving motor.

[0019] An inner side of the speaker frame 1 is provided with a plate groove 11. The plate groove 11 extends along the circumferential direction of the speaker frame 1 and has an upward opening. The PCB board 2 is assembled in the plate groove 11. Among them, the plate groove 11 can be an annular structure or a C-shaped structure. For example, when the plate groove 11 adopts an annular structure, the PCB board 2 can adopt an annular structure or a C-shaped structure. Another example is that when the plate groove 11 adopts a C-shaped structure, the PCB board 2 can also adopt a C-shaped structure. In the embodiment of the present invention, the up and down directions refer to relative directions. Specifically, taking one side of the bottom end of the speaker frame 1 as the downward direction and one side of the top end of the speaker frame 1 as the upward direction.

[0020] On the outer side of the chassis 1, there are a power interface slot 12 and an audio interface slot 13. The power interface slot 12 includes a positive interface slot and a negative interface slot. The power interface slot 12 is located below the board slot 11 and opens downward. The audio interface slot 13 is located at the peripheral edge of the board slot 11 and opens downward. One end of the power input terminal 3 is fixed to and electrically connected to the PCB board 2, and the other end extends downward into the power interface slot 12. One end of the audio input terminal 4 is electrically connected to the PCB board 2 through a lead, and the other end extends downward into the audio interface slot 13, and the audio input terminal 4 is fixed to the bottom wall of the audio interface slot 13. One end of the audio output terminal 5 is fixed to and electrically connected to the PCB board 2, and the other end extends upward. The other end of the audio output terminal 5 is used to connect to the drive motor of the speaker. Among them, directly fixing the power input terminal 3 to the PCB board 2 can omit the lead between the two, and directly fixing the audio output terminal 5 to the PCB board 2 can omit the lead between the two; since the audio interface slot 13 is located at the peripheral edge of the board slot 11, the audio input terminal 4 needs to be connected to the PCB board 2 through a lead. The reason for setting the audio interface slot 13 at the periphery of the board slot 11 is that the audio interface of external devices is relatively large, to prevent the audio interface from being blocked by the magnetic circuit structure or heat dissipation structure on the bottom side of the speaker and unable to be inserted into the audio interface slot 13.

[0021] In this embodiment, the PCB board 2 integrates a power circuit (such as voltage regulation, power supply for the power amplifier, etc.) and a signal circuit (such as a power amplifier circuit). The power input terminal 3 is electrically connected to the power circuit, the power circuit is electrically connected to the signal circuit, the audio input terminal 4 is electrically connected to the signal circuit, and the signal circuit is electrically connected to the audio output terminal 5.

[0022] The speaker assembly structure of the embodiment of the present invention further includes a toggle switch 14 and a contact terminal 6 (equivalent to a fixed contact). The toggle switch 14 is installed on the outer side of the chassis 1 and the installation position is at the peripheral edge of the board slot 11. One end of the contact terminal 6 is fixed to and electrically connected to the PCB board 2, and the other end is used to contact or disconnect from the movable contact of the toggle switch 14 to realize the switch of the speaker. Specifically, the toggle switch 14 can be connected in series in the power input loop in the circuit layout to physically cut off or connect the power supply. Among them, directly fixing the contact terminal 6 to the PCB board 2 can omit the lead between the two.

[0023] The loudspeaker according to the embodiment of the present invention includes the above loudspeaker assembly structure. In addition, the loudspeaker further includes a driving motor 7, and the driving motor 7 is electrically connected to the other end of the audio output terminal 5 through a lead wire. Specifically, the driving motor 7 includes a voice coil, an annular magnet, a T-iron, and a magnetic conductive plate, and the voice coil is electrically connected to the other end of the audio output terminal 5 through a lead wire. In addition, the loudspeaker further includes a diaphragm 8, the top end of the diaphragm 8 is connected to the speaker frame 1, and the bottom end of the diaphragm 8 is connected to the voice coil. These components are all conventional components that make up a loudspeaker, and the related functions can be referred to the prior art.

[0024] The loudspeaker assembly structure and the loudspeaker provided by the embodiment of the present invention integrate the PCB board into the speaker frame to form one component, and the power input terminal, the audio output terminal, the contact terminal, etc. are directly fixed to the PCB board. Only the audio input terminal and the PCB board, and the audio output terminal and the driving motor need to be connected by lead wires. Therefore, the internal structure of the loudspeaker can be effectively simplified and most of the internal lead wires can be omitted, achieving the purpose of simplifying the assembly process to improve production efficiency.

[0025] The above embodiments are only the preferred embodiments of the present invention, and the scope of protection of the present invention cannot be limited thereby. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
