With the development of communication technology, the functions of the terminal are gradually enriched, for example, audio-visual functions and the like are increasingly paid attention to by users, and a sound cavity is generally required to realize good sound effects. However, the size of the speaker is limited for portability, which presents additional challenges to the otherwise scarce interior space. For a loudspeaker, the realization of good sound effect in a limited space is a problem to be solved urgently.

In the related art, the sound tuning powder can be canned in the rear cavity of the conventional audio module, the sound tuning powder is spherical particles, the sound tuning powder has the effect that when the sound membrane of the inner core works, air in the rear cavity can be pushed to pass through the sound tuning powder, the sound tuning powder plays a role similar to adsorption and exchange, air molecules are temporarily adsorbed in the sound tuning powder and then discharged, and the air pressure of the whole rear cavity is reduced, so that the effect similar to the volume expansion is generated. However, the efficiency of the tuning powder is affected by the shape and the size of the rear cavity, and when the shape of the rear cavity is long, the air molecules cannot reach the region where the tuning powder is distributed away from the inner core, so that the adsorption capacity expansion effect cannot be achieved, and the efficiency of the tuning powder is not fully exerted.

In order to overcome the problems in the related art, the present disclosure provides a speaker module and a terminal.

The speaker module of this disclosure includes: a speaker core; the sound cavity comprises a first part and a second part which are communicated with each other, and the first part is communicated with the loudspeaker core; the first end of the first pressurizing pipeline is communicated with the second part of the sound cavity, and the cross section of the first end of the first pressurizing pipeline is larger than that of the second end.

According to the loudspeaker, the pressurizing pipeline is arranged in the first part of the sound cavity, so that the air circulation speed in the first part is increased, and a certain pressure is increased at the same time, so that the sound cavity achieves a better capacity expansion effect, and the effect of sound emitted by the loudspeaker is improved.

Fig. 1 is a schematic diagram illustrating a structure of a speaker module according to an exemplary embodiment. As shown in fig. 1, the speaker module 10 of the present disclosure may include a speaker core 100, a sound cavity 200, and a pressurizing duct 300.

As shown in fig. 1, a speaker module 10 of the present disclosure may include a housing in which a plurality of receiving cavities are provided for receiving corresponding components. For example, speaker core 100 may be placed. For example, it may also be used to form the acoustic cavity 200.

The sound cavity 200 may communicate with the receiving cavity in which the speaker core 100 is placed, i.e., the sound cavity 200 may communicate with the speaker core 200. The communication here means that sound emitted from the speaker core 100 can enter the sound chamber 200, and does not mean that there is no barrier between the accommodating chamber in which the speaker core 100 is placed and the sound chamber 200. For example, in some embodiments, a dust screen or the like may be provided between the housing chamber in which the speaker core 100 is placed and the acoustic chamber 200.

The acoustic chamber 200 may include a first portion 201 and a second portion 202, the first portion 201 and the second portion 202 being in communication with each other. In the present disclosure, the sound cavity 200 may be a rear cavity of the speaker module 10 for enhancing low frequency sound effects. In the present disclosure, the first portion 201 of the acoustic cavity 200 may be in communication with the speaker core 100.

As shown in fig. 1, in the present disclosure, a booster duct 300 may be provided at the first portion 201 of the acoustic cavity 200, and the booster duct 300 may include one or more first booster ducts 301. Sound emitted from the speaker core 100 is transmitted to the second section 202 through the first section 201 of the sound chamber 200. In the present disclosure, at least a part of sound emitted from the speaker core 100 enters the first pressurizing duct 301 while passing through the first portion 201 of the sound chamber 200, and enters the second portion 202 of the sound chamber 200 through the first pressurizing duct 301.

In an exemplary embodiment of the present disclosure, the speaker module 10 may include tuning particles, which may be disposed at the second portion 202 of the sound cavity 200. The tuning particles may be BASS powder, which may be spherical particles having a diameter of 0.2 to 0.4mm, and the internal structure of the BASS powder may be porous.

In the exemplary embodiment of the present disclosure, the sound emitted from the speaker core 100 is propagated through the air, and when the air enters the second portion 202 of the sound chamber 200, the BASS powder may perform an adsorption-exchange-like function to temporarily adsorb air molecules inside the air molecules and then discharge the air molecules, so that the air pressure of the entire rear chamber is reduced, thereby generating a volume-expanding effect.

In an exemplary embodiment of the present disclosure, as shown in fig. 1, the first plenum duct 301 may have a first end 311 and a second end 312. The first end 311 of the first booster duct 301 may be in communication with the speaker core 100, and the second end 312 of the first booster duct 301 is in communication with the second portion 202 of the acoustic chamber 200.

In the exemplary embodiment of the present disclosure, as shown in fig. 1, the cross-section of the first end 311 of the first plenum duct 301 is greater than the cross-section of the second end 312. Specifically, the cross section of the first end 311 of the first plenum duct 301 may be larger than the cross section of the second end 312 in the Z direction.

In the present disclosure, the cross section of the first end 311 of the first booster duct 301 is larger than the cross section of the second end 312, and the air that transmits the sound emitted from the speaker core 100 enters from the first end 311 of the first booster duct 301, is output from the second end 312, and undergoes a width-to-width change inside the first booster duct 301, i.e., the first booster duct 301 is contracted.

The flow of air in the constriction duct may also be regarded as an accelerated flow caused by the blocking, according to the principle of the more blocked and more accelerated, whereby the air is accelerated in the first booster duct 301, while, due to the acceleration, a certain pressure is also generated in the second part 202 of the sound chamber 200 when the air flows out of the first booster duct 301. Based on this, the accelerated air molecules can fully adsorb and exchange with the tuning particles in the second portion 202 of the sound cavity 200, so as to avoid the problem of invalidation of the tuning particles and further improve the sound effect of the speaker module 10.

Fig. 2 is a schematic diagram illustrating a structure of a speaker module according to an exemplary embodiment. As shown in fig. 2, in an exemplary embodiment of the present disclosure, the speaker module 10 may include a first housing 211 and a second housing 212 located at the first portion 201.

As shown in fig. 2, the first casing 211 and the second casing 212 may enclose a first pressurizing pipe 301 therebetween, that is, a cavity formed between the first casing 211 and the second casing 212 is directly used as the first pressurizing pipe 301. That is, the first pressurizing pipe 301 serves as the first portion 201 of the acoustic chamber 200.

As shown in fig. 2, in the embodiment in which the first pressurizing pipe 301 may be enclosed between the first housing 211 and the second housing 212, which is equivalent to the first portion 201 of the sound cavity 200 being the first pressurizing pipe 301, in such an embodiment, all the air entering the sound cavity 200 is accelerated, so that a greater pressure is generated on the second portion 202, and further sufficient adsorption and exchange effects can be generated with tuning particles, so that the problem of inefficiency of the tuning particles is avoided, and further, the sound effect of the speaker module 10 is further improved.

In the present disclosure, the first housing 211 and the second housing 212 may be bonded to each other, increasing sealability. Specifically, the first housing 211 and the second housing 212 may be bonded by a sealant. In the manufacturing process, the first housing 211 and the second housing 212 can be formed by using a mold respectively, and then bonded

It is noted that the present disclosure is not limited thereto, and in other embodiments, less than two housings or more than two housings may be included to form the first plenum duct 301.

As shown in fig. 3, in an exemplary embodiment of the present disclosure, the speaker module 10 may include a third housing 203 positioned at the first portion 201 of the sound chamber 200, and a first pressurizing duct 301 is formed in the third housing 203. In such an embodiment, since the first pressurizing pipe 301 is formed in the third housing 203, the first pressurizing pipe 301 has a better sealing effect, resulting in a better sound effect.

Fig. 4 is a schematic structural view of a speaker module according to an exemplary embodiment. As shown in fig. 4, in an exemplary embodiment of the present disclosure, the first plenum 301 may be a spiral pipe. The helical structured conduit may further accelerate the air, thereby further pressurizing the second portion 202.

Fig. 5 is a schematic diagram showing a structure of a speaker module according to an exemplary embodiment. As shown in fig. 5, in an exemplary embodiment of the present disclosure, the first plenum 301 may be a variable pitch helical pipe. The variable pitch helical structured conduit may further accelerate the air, thereby further pressurizing the second section 202.

As shown in fig. 5, in an exemplary embodiment of the present disclosure, the pitch of the helical piping may gradually increase from the input end to the output end. Specifically, the pitch of the first pressurizing pipe 301 gradually increases in the direction from the speaker core 100 to the sound chamber 200. I.e. the pitch of the first plenum duct 301 increases gradually from the first end 311 to the second end 312. By means of the arrangement, gradual acceleration of the internal air can be achieved, the air can be accelerated more uniformly and comprehensively, and then a better acceleration and pressurization effect is achieved.

In an exemplary embodiment of the present disclosure, as shown in fig. 5, the first pressurizing pipe 301 may have a circular cross section, i.e., the first pressurizing pipe 301 may be a circular pipe. However, the present disclosure is not limited thereto, and in other possible embodiments, the first pressurizing duct 301 may be a square duct, a triangular duct, or other regular or irregular duct.

In the exemplary embodiment of the present disclosure, as shown in fig. 5, the diameter of the first pressurizing pipe 301 gradually increases in the direction from the speaker core 100 to the sound chamber 200.

Specifically, the second end 322 of the second plenum duct 302 may have a larger cross-section than the first end 321 in the Z-direction.

In the present disclosure, the cross section of the second end 322 of the second booster duct 302 is larger than the cross section of the first end 321, and the air of the second portion 202 enters from the second end 322 of the second booster duct 302, is output from the first end 321, undergoes a wide-to-narrow inside the second booster duct 302 in the direction from the sound chamber 200 to the speaker core 100, i.e., the second booster duct 302 is contracted.

The flow of air in the constriction duct may also be regarded as an accelerated flow caused by the obstruction, according to the principle of more blocking the more acceleration, and thus the air is accelerated in the second plenum duct 302. Based on this, the accelerated air molecules are accelerated back to the placement cavity where the speaker core 100 is placed at the second portion 202 of the sound cavity 200 to form a circulation, thereby solving the problem that tuning particles in the far back cavity region are ineffective.

In the present disclosure, the arrangement, shape, structure, etc. of the second plenum duct 302 may be the same as or similar to the first plenum duct 301. For example, in the exemplary embodiment of the present disclosure, the speaker module 10 may include the first housing 211 and the second housing 212 located at the first portion 201, and the second pressurizing duct 302 may be enclosed between the first housing 211 and the second housing 212, i.e., a cavity formed between the first housing 211 and the second housing 212 directly serves as the second pressurizing duct 302. That is, the second plenum duct 302 acts as the first portion 201 of the acoustic chamber 200.

In the present disclosure, the first housing 211 and the second housing 212 may be bonded to each other, increasing sealability. Specifically, the first housing 211 and the second housing 212 may be bonded by a sealant. In the manufacturing process, the first housing 211 and the second housing 212 can be formed by using a mold respectively, and then bonded
