the first loudspeaker unit 2 is mounted on the side wall of the first partition 1, the back of the first loudspeaker unit 2 is arranged in the first inner cavity 5, and the first loudspeaker unit 2 is used for pushing air in the first inner cavity 5 to vibrate through a diaphragm;
the second speaker unit 3 is mounted on the side wall of the first partition 1, the back of the second speaker unit 3 is disposed in the first inner cavity 5, and the second speaker unit 3 is used for radiating sound waves to a sound outlet 7 of the electronic device;
wherein the second speaker unit 3 is opposite in phase to the first speaker unit 2.

Because the first speaker unit 2 is used for pushing the air in the first inner cavity 5 to vibrate through the vibrating diaphragm, specifically, after the first speaker unit 2 receives a corresponding audio signal, the vibrating diaphragm of the first speaker unit 2 vibrates with low frequency, large amplitude and high sensitivity, and further drives the air in the first inner cavity 5 to vibrate, when the air in the first inner cavity 5 is driven by the vibrating diaphragm of the first speaker unit 2 to be extruded, the air pressure is increased, and more space is provided for the vibrating diaphragm of the second speaker unit 3 to expand outwards; when the air in the first inner cavity 5 is driven by the diaphragm of the first speaker unit 2 to be expanded, the air pressure is reduced, so that more space is provided for the inward compression of the diaphragm of the second speaker unit 3, and a larger acoustic back cavity effect is obtained by the second speaker unit 3. When the first speaker unit 2 is attached to the first partition member 1, the vibrating end of the first speaker unit 2 faces the second internal cavity 6; the equivalent volume of the first interior 5 is thus controlled and the diaphragm amplification of the second loudspeaker unit 3 is controlled.
The second inner cavity 6 forms a sealed acoustic front cavity of the first loudspeaker unit 2, and the first inner cavity 5 forms a common acoustic back cavity of the first loudspeaker unit 2 and the second loudspeaker unit 3; when the vibrating diaphragms of the first loudspeaker unit 2 and the second loudspeaker unit 3 vibrate simultaneously, the air in the sealed first inner cavity 5 is synchronously compressed or expanded through the first loudspeaker unit 2, and because the phase of the second loudspeaker unit 3 is opposite to that of the first loudspeaker unit 2, and the main bodies of the first loudspeaker unit 2 and the second loudspeaker unit 3 are both positioned in the first inner cavity 5, the second loudspeaker unit 3 obtains larger equivalent shared back cavity volume when vibrating, the low-frequency effect can be enhanced, and the non-linearity of the compliance of the sealed back cavity is improved; the electronic equipment applying the loudspeaker device structure can obtain better low-frequency output improvement without designing an overlarge independent acoustic back cavity.
In addition, the size of the effective volume of the acoustic common back cavity of the first inner cavity 5 can be controlled by selectively adjusting the caliber, performance and input power of the first loudspeaker unit 2.

Please refer to fig. 3 and fig. 9, embodiment two: the first partition 1 may be an electronic device, and the first partition 1 and the internal housing structure of the electronic device are constructed as a single body when the electronic device is manufactured, so that the first partition inner wall 110 is connected with the electronic device inner wall 410 to enclose a first inner cavity 5, and the first partition outer wall 120 and the electronic device inner wall 410 enclose a sealed second inner cavity 6.
Referring to fig. 7 and 10, the electronic device includes a second partition 8, the second partition 8 is disposed in the electronic device inner cavity 4, and the second partition 8 is used for sealing the second inner cavity 6 with the electronic device inner wall 410 and the first partition outer wall 120.
Example three: some electronic devices, such as projectors and all-in-one machines, have inner cavities which are not like electronic devices such as mobile phones and tablet computers, the inner cavities are sealed and not communicated with the outside, and the housings of the projectors and all-in-one machines are usually provided with heat dissipation holes for communicating with the outside or holes for other purposes, so that the inner cavity 4 of the electronic device can be communicated with the outside, and the inner cavity 4 of the electronic device causes that the second inner cavity 6 cannot be a sealed acoustic front cavity of the first speaker unit 2 well.
In this embodiment, the second partition 8 may be a partition corresponding to the contour of the inner cavity 4 of the electronic device, and plays a role in blocking the communication between the second inner cavity 6 and a heat dissipation hole or other through holes of the electronic device, so that the second inner cavity 6 becomes a sealed cavity; or the second separator 8 may also be manufactured integrally with the electronic device when manufactured with the housing of the electronic device. By providing the second partition 8, the sealing property of the second internal chamber 6 is maintained, preventing the second internal chamber 6 from degrading as an acoustic front chamber of the first speaker unit 2.

Preferably, the second partition 8 is displaceable.
In the existing loudspeaker arrangement structure with the open type back cavity design, the size of the back cavity cannot be controlled due to the fact that the inner size of an inner cavity 4 of electronic equipment is limited and a sealing area with a specified size cannot be constructed.
Example four: when the second separator 8 is a partition structure non-integral with the inner wall 410 of the electronic device, and the position of the second separator 8 can be moved, the volume of the sealed second inner cavity 6 can be adjusted by moving the position of the second separator 8, and the volume of the second inner cavity 6 can be set by user-definition, so that a better sound wave output effect can be obtained by debugging.
