[0020] In Figure 1 it includes:

[0021] 1 - First speaker unit; 11 - First diaphragm; 12 - First voice coil; 13 - First magnet; 14 - First magnetic conduction plate; 2 - Second speaker unit; 21 - Second diaphragm; 22 - Second voice coil; 23 - Second magnet; 24 - Second magnetic conduction plate; 3 - Intermediate sleeve; 31 - Sleeve inner cavity; 32 - Front side annular groove; 33 - Rear side annular groove; 4 - Front side end cap; 41 - Sound outlet hole; 5 - Rear side end cap; 51 - Tone adjustment hole. Specific embodiments

[0022] The present utility model will be described below in conjunction with specific embodiments.

[0023] Embodiment 1, as Figure 1 shown, a new push - pull headphone speaker structure includes symmetrically and spaced - apart first speaker unit 1 and second speaker unit 2. The first speaker unit 1 includes a first diaphragm 11, a first voice coil 12 installed on the first diaphragm 11, and a first magnet 13 cooperating with the first voice coil 12. The second speaker unit 2 includes a second diaphragm 21, a second voice coil 22 installed on the second diaphragm 21, and a second magnet 23 cooperating with the second voice coil 22. The first diaphragm 11 and the second diaphragm 21 vibrate synchronously and in opposite directions.

[0024] Among them, as Figure 1 shown, the new push - pull headphone speaker structure further includes a hollow - shaped intermediate sleeve 3. An inner cavity 31 that completely penetrates along the front - rear direction is formed inside the intermediate sleeve 3. The first diaphragm 11 and the second diaphragm 21 are respectively located inside the sleeve inner cavity 31.

[0025] Furthermore, as Figure 1 shown, a front - side end cap 4 is installed at the front - end opening position of the sleeve inner cavity 31 at the front - end portion of the intermediate sleeve 3. The front - side end cap 4 is provided with a sound outlet hole 41 that completely penetrates along the front - rear direction. The first magnet 13 is fixedly installed on the inner wall of the front - side end cap 4. The edge position of the first diaphragm 11 is clamped and fixed to the front - end portion of the intermediate sleeve 3 through the edge portion of the front - side end cap 4.

[0026] Even further, as Figure 1 shown, a rear - side end cap 5 is installed at the rear - end opening position of the sleeve inner cavity 31 at the rear - end portion of the intermediate sleeve 3. The second magnet 23 is fixedly installed on the inner wall of the rear - side end cap 5. The edge position of the second diaphragm 21 is clamped and fixed to the rear - end portion of the intermediate sleeve 3 through the edge portion of the rear - side end cap 5.

[0027] In the novel push - pull headphone speaker structure of the first embodiment, the first voice coil 12 cooperates with the first magnet 13 and drives the first diaphragm 11 to vibrate. The second voice coil 22 cooperates with the second magnet 23 and drives the second diaphragm 21 to vibrate. And because the vibration directions of the first diaphragm 11 and the second diaphragm 21 are opposite, a push - pull effect is formed. Under the condition of the same diameter, the amplitude of the diaphragm can be effectively increased, and then the bass effect can be enhanced.

[0028] When the first diaphragm 11 and the second diaphragm 21 that perform synchronous reverse actions vibrate in the sleeve inner cavity 31 of the middle sleeve 3, the sound generated by the vibration of the first diaphragm 11 and the second diaphragm 21 comes out from the sound outlet hole 41 of the front end cap 4 to achieve single - side sound output of the headphone product.

[0029] In addition, for the first speaker unit 1 and the second speaker unit 2 of the first embodiment, they only include a voice coil, a diaphragm, and a magnet; compared with the prior art, the structure of the speaker unit is simple.

[0030] Based on the above - mentioned situation, through the above - mentioned structural design, the novel push - pull headphone speaker structure of the first embodiment has the advantages of novel design and simple structure, and can be effectively applied to headphone products.

[0031] Embodiment 2, as Figure 1 shown, the difference between the second embodiment and the first embodiment is that: a front - side annular groove 32 is provided at the front - end opening position of the sleeve inner cavity 31 of the middle sleeve 3. The edge part of the first diaphragm 11 and the edge part of the front end cap 4 are respectively located in the front - side annular groove 32. The edge part of the front end cap 4 is adhesively connected to the front end part of the middle sleeve 3, and the edge part of the first diaphragm 11 is clamped and fixed in the front - side annular groove 32 through the edge part of the front end cap 4.

[0032] Similarly, a rear - side annular groove 33 is provided at the rear - end opening position of the sleeve inner cavity 31 of the middle sleeve 3. The edge part of the second diaphragm 21 and the edge part of the rear end cap 5 are respectively located in the rear - side annular groove 33. The edge part of the rear end cap 5 is adhesively connected to the rear end part of the middle sleeve 3, and the edge part of the second diaphragm 21 is clamped and fixed in the rear - side annular groove 33 through the edge part of the rear end cap 5.

[0033] It should be explained that in the second embodiment, the front - side annular groove 32 is used to position the edge part of the first diaphragm 11 and the edge part of the front end cap 4, that is, the rapid installation and positioning of the first diaphragm 11 and the front end cap 4 can be realized, so as to improve the assembly convenience.

[0034] Similarly, in the second embodiment, the rear - side annular groove 33 is used to position the edge part of the second diaphragm 21 and the edge part of the rear end cap 5, that is, the rapid installation and positioning of the second diaphragm 21 and the rear end cap 5 can be realized, so as to improve the assembly convenience.

[0035] Embodiment 3, as Figure 1 shown, the difference between this Embodiment 3 and Embodiment 1 is that: the rear end cover 5 is provided with a tuning hole 51.
