In an embodiment of the present invention, as shown in fig. 1 and 2, the acoustic module 100 includes a housing 130, and an accommodating space 132 is formed in the housing 130. The accommodating space 132 is used for accommodating a speaker.

Further, as shown in fig. 2, the acoustic module 100 further includes a first speaker 110 and a second speaker 120, where the first speaker 110 and the second speaker 120 are disposed in the accommodating space 132 of the housing 130, and a surface of the first speaker 110 where the magnetizer 1101 is disposed and a surface of the second speaker 120 where the magnetizer 1201 is disposed are disposed opposite to each other, so that a vibration direction of the first speaker 110 is opposite to a vibration direction of the second speaker 120.

In one example, the acoustic module further includes an audio Digital Signal Processor (DSP) (not shown) electrically connected to the first speaker and the second speaker and configured to mix left and right channel low frequency signals together such that the electrical signals received by the first speaker and the second speaker are the same, e.g., the amplitude and phase of the electrical signals are the same, thereby causing the vibration amplitude of the first speaker and the second speaker to be the same. Alternatively, the low frequency signal may be, for example, a 300Hz to 20Hz low frequency signal, or other low frequency signal.

The structure of the speakers will be briefly described below to facilitate understanding of the structures of the first speaker 110 and the second speaker 120. The speaker generally includes a magnetic circuit system, where the magnetic circuit system includes a magnetizer, such as a U-iron, and the magnetizer is a magnetizer and has magnetic gathering and magnetic conducting functions.

Optionally, the magnetic conductor has a receiving cavity therein for other components of the magnetic circuit system. More specifically, the U-shaped iron comprises a bottom and peripheral side walls protruding outwards from the bottom, and a space area formed by the peripheral side walls and the bottom forms the accommodating cavity.

In one example, the magnetic circuit system further comprises a magnet, which is disposed in the accommodating cavity and is used for generating a magnetic field, so that when the voice coil is placed in the magnetic field, when the voice coil is energized, the current receives the acting force of the magnetic field, so that the voice coil vibrates, and the voice cone connected with the voice coil is driven to vibrate to make a sound.

In order to enable the magnet to be placed in the accommodating chamber of the magnetizer and to form a magnetic gap between the inner side wall of the magnetizer and the peripheral edge of the magnet, the cross-sectional area of the magnet is smaller than that of the accommodating chamber.

In one example, the magnetic circuit system further comprises a washer arranged on the magnet and connected with the magnet, wherein a magnetic gap is formed between the magnet and the U-shaped iron and between the washer and the inner side wall of the U-shaped iron. The washer has the function of magnetic conduction, and is also called a magnetic conduction plate, and the U iron and the washer have the function of forming a good magnetic loop, so that the magnetic induction intensity B is increased, and a uniform magnetic field required by the movement of the voice coil is provided. The bass distortion of the loudspeaker is determined by the matching of the thickness of the washer and the winding width of the voice coil part of the voice coil.

In one example, the magnetic circuit system further includes a voice coil, one end of the voice coil extends into the magnetic gap in the accommodating cavity, the voice coil further includes two electrode ends, which are electrically connected to the electrodes of the power supply respectively, so as to provide current to the voice coil, and the current, when subjected to the acting force of the magnetic field, causes the voice coil to vibrate, and drives the voice cone connected with the voice coil to vibrate and make a sound.

The bottom plate is also provided with an accommodating groove, and an opening of the accommodating cavity of the U-shaped iron faces the accommodating groove. A cavity is formed between the magnetic circuit system and the side wall of the accommodating groove, and a voice coil of the magnetic circuit system is arranged in the cavity.

More specifically, the voice coil of the magnetic circuit system passes through the receiving slot into the magnetic gap in the U-iron. The loudspeaker also comprises a sound cone which is arranged above the voice coil of the magnetic circuit system and is connected with the voice coil so as to generate sound along with the vibration of the voice coil when the voice coil is electrified.

More specifically, the support is further provided with a mounting groove (not shown) for mounting the voice cone, the mounting groove and the receiving groove are arranged opposite to the mounting groove, wherein the support is internally provided with a cavity for receiving at least part of the voice coil and the like. The complete speaker structure may also include other structures such as a diaphragm, and details thereof are not described herein.

In order to solve the above problem, the housing 130 is further configured to cancel out the vibration conduction of the first speaker and the second speaker in opposite directions.

Further, as shown in fig. 2, the housing 130 includes a supporting structure 1301 disposed in the accommodating space, the first speaker 110 and the second speaker 120 are disposed on two sides of the supporting structure 1301, and the supporting structure 1301 is configured to support the first speaker 110 and the second speaker 120 and cancel out the vibration conduction of the first speaker 110 and the second speaker 120 in opposite directions, so as to reduce the vibration energy generated by the speakers from the source.

Wherein, the material of the shell and the supporting structure can be rigid material, because the rigid material has enough strength, it can play a good supporting role for the first loudspeaker and the second loudspeaker, meanwhile, the rigid material can adopt material with higher resonance frequency, such as material with resonance frequency larger than threshold resonance frequency, especially metal material, the resonance frequency can refer to the natural frequency of the shell and the supporting structure, it reflects the vibration of the shell and the supporting structure, because the rigid material can adopt material with higher resonance frequency, it can protect the shell and the supporting structure from the influence of the vibration radiated by the air flow and the loudspeaker, thereby avoiding the vibration interference of the vibration of the shell and the supporting structure to the equipment including the acoustic module, the threshold resonance frequency can be set reasonably according to the actual body vibration frequency of the first loudspeaker and the second loudspeaker, and is not particularly limited herein.

For example, the first support 1104 of the first speaker 110 and the second support 1204 of the second speaker 120 may be fixedly connected to the housing 130 by, for example, bonding or caulking, further, for example, the first end of the first support 1104 may be provided with a cone 1102, the first end of the first support 1104 may have a mounting portion 1105 extending outward of the cone 1202 by a partial width, the second speaker 120 may include the second support 1204, the first end of the second support 1204 may be provided with the cone 1202, the first end of the second support 1204 may have a mounting portion 1203 extending outward of the cone 1202 by a partial width, the mounting portion 1103 of the first speaker 110 may be fixedly connected to the housing 130 by, for example, bonding or caulking, and the mounting portion 1203 of the second speaker 120 may be fixedly connected to the housing 130 by, for example, bonding or caulking, or the like.

In one example, as shown in fig. 1, fig. 2 and fig. 4, the acoustic module further includes two shock absorbing structures 140 respectively disposed between the mounting surface 1105 of the first speaker 110 and the housing 130 and between the mounting surface 1205 of the second speaker 120 and the housing 130, so as to prevent any hard contact between the first speaker 110 and the housing 130 and between the second speaker 120 and the housing 130, thereby ensuring buffering and shock absorbing effects between the first speaker 110 and the housing 130 and between the second speaker 120 and the housing 130, and preventing the sound effect of the acoustic module due to the influence of the hard contact shocking sound.

By way of further example, the mounting surface 1105 of the first speaker 110 includes a peripheral sidewall of the mounting portion 1103 of the first speaker 110, the sidewall and a surface of the housing facing the sidewall are disposed with the shock absorbing structure 140 therebetween, e.g., the shock absorbing structure 140 surrounds the peripheral sidewall of the mounting portion 1103, the mounting surface 1205 of the second speaker 120 includes a peripheral sidewall of the mounting portion 1203 of the second speaker 120, the sidewall and a surface of the housing facing the sidewall are disposed with the shock absorbing structure 140 therebetween, e.g., the shock absorbing structure 140 surrounds the peripheral sidewall of the mounting portion.
