The term "and/or" appearing in the present application may be an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" in this application generally indicates that the former and latter related objects are in an "or" relationship.
The terms "first," "second," and the like in the description and in the claims of the present application and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Moreover, the terms "comprises," "comprising," and any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or modules is not necessarily limited to those steps or modules explicitly listed, but may include other steps or modules not expressly listed or inherent to such process, method, article, or apparatus.
The speaker module is an important device in electronic equipment such as smart phones and tablet computers. Usually, the speaker module is provided with two cavities, namely a first sound cavity and a second sound cavity. Due to the limitations of the electronic device itself, the second sound cavity of the speaker module cannot be enlarged infinitely to improve the sound quality. In actual production, the second sound cavity of the speaker module can be made to be open, so that the second sound cavity of the speaker module is communicated with the internal cavity of the electronic equipment. As shown in fig. 1, the speaker includes a housing 101, and the rear cavity of the speaker module includes a sound hole 102, where the sound hole 102 may be connected to an internal cavity of the electronic device, and in this case, the internal cavity of the whole electronic device may be regarded as a second sound cavity of the speaker module. In this way, the volume of the second sound cavity of the loudspeaker module is enlarged, so that the acoustic performance of the loudspeaker module can be improved.
Because the second sound cavity of the loudspeaker module is open, if the electronic equipment comprising the loudspeaker module is not sealed to a high degree, acoustic short circuit can be caused, and the audio effect is weakened. Therefore, the electronic equipment comprising the loudspeaker module has higher requirement on sealing performance. When the sound generating device of the loudspeaker module vibrates to generate sound, the sound generating device can drive airflow in the internal cavity of the electronic equipment to move, and the airflow movement can cause the shell of the electronic equipment or other parts of the electronic equipment to resonate, so that noise occurs.
Therefore, the first embodiment of the present application provides a speaker module, which can be applied to electronic devices such as mobile phones, tablet computers, and personal computers. As shown in fig. 2, the speaker module may include:
the sound production device comprises a shell 201, a sound production device 202 and a sound cavity formed by the shell 201 and divided into a first sound cavity 203 and a second sound cavity 204 by the sound production device 202.
The positional relationship among the housing 201, the sound generating device 202, the first sound cavity 203 and the second sound cavity 204 can be understood by referring to fig. 3, and fig. 3 is a right side view of the speaker module shown in fig. 2. The lower surface of the sound generating device 202 and the housing 201 may form a closed cavity, which is the first sound cavity 203. The housing 201 encloses an inner cavity, which is occupied by the second sound cavity 203, except for the space occupied by the sound generating device 202 and the first sound cavity 203.
A portion of the casing 201 surrounding the second acoustic chamber is provided with a first acoustic hole 205. Fig. 2 exemplarily arranges the first sound hole 205 on the left side surface of the housing 201. In practical production, the first sound hole 205 may also be disposed on an upper surface or a lower surface of a portion of the casing 201 surrounding the second sound cavity, which is not limited herein. At least one timbre adjusting device 206 is disposed in the second sound cavity 204, and the at least one timbre adjusting device 206 may be made of zeolite, carbon fiber, soundproof cotton, and other materials having micro-pores, which are not limited herein. One or more tone quality adjusting devices 206 may be disposed in the second acoustic cavity 204, without limitation.
The first sound hole 205 can connect the second sound cavity 204 with the inner cavity of the electronic device including the speaker module, so as to improve the acoustic performance of the speaker module and improve the audio effect of the whole electronic device. When the sound generating device 202 generates sound, the sound quality adjusting device 206 can obstruct the airflow entering the internal cavity of the electronic device from the first sound hole 205, so as to suppress the housing of the electronic device or other parts of the electronic device from resonating and avoid noise. Because the sound quality adjusting device 206 can obstruct the air flow entering the inner cavity of the electronic device from the first sound hole 205, even if the electronic device including the speaker module is not sealed to a high degree, the sound short circuit is not caused, the audio effect is not weakened, and the requirement on the sealing performance of the electronic device including the speaker module is low.
In the first embodiment of the present application, a partition board may be further disposed in the second sound cavity, a second sound hole may be disposed on the partition board, and the at least one sound quality adjusting device may be disposed between the first sound hole and the partition board. The first sound hole, the at least one sound quality adjusting device and the second sound hole can form an air flow channel, so that the second sound cavity of the loudspeaker module is communicated with an inner cavity of electronic equipment comprising the loudspeaker module.

The tone quality adjusting means 307 may be made of zeolite, carbon fiber, soundproof cotton, and other materials having micro pores, which are not limited herein. The shape of the timbre adjusting device 307 is not limited, and the timbre adjusting device 307 may be a rectangular parallelepiped structure or a square structure, but is not limited thereto. Since the shape of the timbre adjusting device 307 is regular, the partition 304, the cover 301 and the bottom 303 can fix the timbre adjusting device 307. When the loudspeaker module or the electronic equipment where the loudspeaker module is located is shaken, the position of the sound quality adjusting device relative to the loudspeaker module does not move.

The damping net is disposed in the first sound hole 306 and the second sound hole 307 by means including but not limited to adhesion, heat melting or injection molding.
In the speaker module according to the second embodiment, a partition 304 may be disposed in the second sound cavity, the at least one timbre adjusting device 307 may be disposed between the partition 304 and the side of the case bottom 303 where the first sound hole 306 is disposed, and the second sound hole 305 may be disposed on the partition 304. The first sound hole 306, the at least one sound quality adjusting device 307 and the second sound hole 305 can enable the second sound cavity of the speaker module to be connected with the inner cavity of the electronic device comprising the speaker module, so that the acoustic performance of the speaker module can be improved, and the audio effect of the whole electronic device can be improved. Meanwhile, the damping net and the sound quality adjusting device 307 on the first sound hole 306 and the second sound hole 305 can generate friction action on the air flow, so that part of sound energy is converted into heat energy, the air flow entering the electronic equipment from the second sound cavity of the loudspeaker module is blocked from moving, part of sound energy is converted into heat energy, and resonance noise of each component in the electronic equipment can be inhibited. The damping net and the sound quality adjusting device 307 can block the air flow movement entering the inner cavity of the electronic equipment from the first sound hole 306, even if the electronic equipment comprising the loudspeaker module is not high in sealing degree, the sound short circuit can not be caused, the audio effect can not be weakened, and therefore the requirement on the sealing performance of the electronic equipment comprising the loudspeaker module is low.
