In some embodiments, at least two speaker bodies 100 are disposed in parallel, and the mounting cavity 201 and the corresponding cavity 202 are disposed on two sides of the speaker bodies 100. The installation cavity 201 is a front cavity of the loudspeaker assembly, the corresponding cavity 202 is a rear cavity of the loudspeaker assembly, the extension cavity 203 is arranged on one side of the corresponding cavity 202 and communicated with the corresponding cavity 202, or the extension cavity 203 is arranged on one side of the installation cavity 201 and communicated with the installation cavity 201.

In particular, the accommodation cavity may be a straight cylinder cavity, a cubic cavity or a curved tube cavity. When the speaker body 100 is disposed in the accommodating cavity, the diaphragm (or the speaker body 100 itself) thereof may partition the accommodating cavity to form the mounting cavity 201 and the corresponding cavity 202, and the diaphragm of the speaker body 100 vibrates to push the air in the mounting cavity 201 and the corresponding cavity 202 to vibrate. Certainly, in other embodiments, the corresponding cavity 202 is arranged opposite to the installation cavity 201, and at least two speaker bodies 100 are arranged in the installation cavity 201, so that the at least two speaker bodies 100 correspond to the corresponding cavity 202, and when the at least two speaker bodies 100 are connected and then work, the diaphragms of the at least two speaker bodies can push the air in the corresponding cavity 202, and further, the sound transmission effect is realized through the vibration of the air in the corresponding cavity 202.

In some embodiments, the corresponding cavity 202 includes a first cavity and a second cavity separately disposed, a spacer 300 is disposed in the extending cavity 203, the spacer 300 extends along the direction from the corresponding cavity 202 to the extending cavity 203, and divides the extending cavity 203 into a first extending sub-cavity 2031 and a second extending sub-cavity 2032; the first cavity is in communication with the first extended subchamber 2031 and the second cavity is in communication with the second extended subchamber 2032; the spacer 300 is provided with a communication hole 310, and the communication hole 310 communicates the first extension subcavity 2031 and the second extension subcavity 2032.

In other embodiments, the corresponding cavity 202 is a single cavity, the spacer 300 is disposed in the extending cavity 203, and the spacer 300 extends along the direction from the corresponding cavity 202 to the extending cavity 203 and divides the extending cavity 203 into a first extending sub-cavity 2031 and a second extending sub-cavity 2032.

Since the corresponding cavity 202 corresponds to at least two speaker bodies 100, the corresponding cavity 202 may have sub-cavities corresponding to each speaker body 100 respectively and having the same number, and the sub-cavities may be arranged in a through manner, that is, the sub-cavities form an integral cavity together; or the at least two sub-cavities can be separated by a partition board, the partition board is provided with a via hole, and the via hole is communicated with the at least two sub-cavities; or a partition board is arranged in the corresponding cavity 202, the partition board divides the corresponding cavity 202 into at least two sub-cavities, and at least one end of the partition board does not abut against the cavity wall of the corresponding cavity 202; or the partition board may extend along the direction from the corresponding cavity 202 to the extending cavity 203, a via hole may be formed in a portion of the partition board located in the extending cavity 203, and two ends of the partition board may respectively support the cavity wall of the corresponding cavity 202 and the cavity wall of the extending cavity 203. The sub-chambers are connected so that the space of the entire corresponding chamber 202 is large. The air within the corresponding cavity 202 reacts less to the sound waves and thereby facilitates the propagation of sound waves at low frequencies to cause the speaker assembly to emit sound at low frequencies.

Hereinafter, two speaker bodies 100 are provided as an example, and the two speaker bodies 100 may be arranged in parallel or may be arranged in a shifted manner. When the two speaker bodies 100 are operated simultaneously, the two speaker bodies 100 may be connected in the positive phase or in the negative phase. Specifically, when two speaker bodies 100 are being connected, the sound emission loudness of the speaker assembly can be increased. When the two speaker bodies 100 are connected in opposite phase, at this time, the vibrating diaphragms of the two speaker bodies 100 vibrate to push the air in the corresponding cavities 202 in opposite directions, so that the sound waves in the corresponding cavities 202 can at least partially cancel each other, the reaction force of the air in the corresponding cavities 202 to the sound waves is reduced, and further, low-frequency sound can be emitted; in addition, since the phases of the sound waves generated by the two oppositely connected speaker bodies 100 are opposite in the far field, the far field noise cancellation effect can be achieved. In the near field, because the two speaker bodies 100 are connected in opposite phases, the difference between the sound paths from the sound waves radiated by the two speaker bodies 100 to the human ears is large, so that the loudness emitted by the two speaker bodies 100 in the near field is not lost too much due to the opposite phases of the two speaker bodies, and therefore, when the two speaker bodies 100 are connected in opposite phases, the human ears in the near field can still hear the sound. Specifically, the two speaker bodies 100 may be of the same type, so that when the two speaker bodies 100 have the same amplitude in the far field and the opposite phases, the far-field noise cancellation effect can be achieved.

Additionally, the utility model discloses extension chamber 203 of casing 200 among the technical scheme can locate the lateral part that corresponds chamber 202 and with correspond chamber 202 intercommunication, make extend chamber 203 and correspond chamber 202 and become a bigger chamber, and then make the cavity of the vibrating diaphragm one side of speaker body 100 expand, perhaps this extension chamber 203 can regard as leading the sound passageway, vibrating diaphragm vibration at speaker body 100 is when the air that corresponds chamber 202 and extension chamber 203 is promoted in order to promote, the air is less to the reaction force of sound wave, thereby can realize the effect that the low frequency is sounded. The utility model discloses the lateral part of installation cavity 201 still can be located to casing 200's extension chamber 203 among the technical scheme, and extension chamber 203 can regard as to locate the leading note pipe that is located same cavity with speaker body 100 this moment. Specifically, the extension cavity 203 may be a straight channel or a curved channel.

It should be noted that, in the technical solution of the present invention, the extension cavity 203 is disposed on one side of the corresponding cavity 202, which means that the extension cavity 203 does not extend in the setting direction of the corresponding cavity 202 and the installation cavity 201. For example, when the mounting cavity 201 corresponds to the corresponding cavity 202 in the front-rear direction, the extension cavity 203 is not provided behind or in front of the corresponding cavity 202, but is provided above, below, to the left or to the right of the corresponding cavity 202, or the like. Similarly, the extension cavity 203 is disposed on one side of the mounting cavity 201, which means that the extension cavity 203 does not extend in the direction of the corresponding cavity 202 and the mounting cavity 201. For example, when the mounting cavity 201 corresponds to the corresponding cavity 202 in the front-rear direction, the extension cavity 203 is not provided in the front or rear direction of the mounting cavity 201, but provided above, below, to the left or right of the mounting cavity 201. It can be understood that when the extended cavity 203 is disposed on the head-mounted device, the extended cavity 203 may be close to the human ear, and the corresponding cavity 202 and the mounting cavity 201 may be far away from the human ear, so that on one hand, the speaker assembly is at least partially close to the human ear, so that the sound quality heard by the human ear is better; on the other hand, the corresponding cavity 202 and the mounting cavity 201 with larger thickness are avoided from being close to the ear of the human body, so that the user has poor wearing experience.

The vibrating diaphragms of the loudspeaker bodies 100 vibrate to drive the air in the corresponding cavities 202 to vibrate, so that sound is emitted, when at least two loudspeaker bodies 100 are in positive connection, because the phases of sound waves radiated by the two loudspeaker bodies 100 are the same, the amplitude of the whole loudspeaker assembly can be increased, and the sound volume can be increased; meanwhile, as the loudspeaker assembly is provided with the extension cavity 203, the extension cavity 203 serves as a bass tube, so that the overall resonance frequency of the loudspeaker assembly can be reduced, and more low-frequency sounds can be emitted. When the two speaker bodies 100 are connected in opposite phase, because the two speakers are both communicated with the corresponding cavity 202, the phases of the sound waves radiated by the diaphragms of the speaker bodies 100 in the corresponding cavity 202 are opposite, and the sound waves radiated by the two speakers are largely cancelled; meanwhile, the sound wave phase of the sound wave radiated by the diaphragm of the loudspeaker body 100 is opposite in the far field outside the installation cavity 201 when the sound wave is emitted through the installation cavity 201, so that the sound waves radiated by the two are mutually offset in the far field to a great extent, and the loudspeaker assembly has a certain degree of noise elimination effect in the far field; however, in the near field, the sound path difference between the sound waves emitted from the two speaker bodies 100 through the mounting cavity 201 and the ears of the user is large, so when the two speaker bodies 100 are connected in opposite phase, the sound emitted from the speakers can still be clearly heard by the ears of the person in the near field. And because when corresponding two speaker bodies 100 settings of chamber 202 correspondence, the sound wave of two speaker body 100's vibrating diaphragm radiation is at the chamber 202 interior to a great extent of correspondence offset each other, consequently correspond the air in the chamber 202 less to the reaction force of sound wave, and then less to the resistance of the sound wave of low frequency, make the utility model discloses speaker component among the technical scheme can send low frequency sound. In addition, when the extension cavity 203 is arranged on one side of the corresponding cavity 202 and communicated with the corresponding cavity 202, or the extension cavity 203 is arranged on one side of the installation cavity 201 and communicated with the installation cavity 201, the length of the shell 200 of the whole loudspeaker assembly in the extension direction of the extension cavity 203 is larger, and further when the loudspeaker assembly is arranged on the head-mounted device, the shell 200 can extend to the vicinity of the ears of a user, so that the user has better hearing experience when wearing the head-mounted device. In addition, the arrangement of the extended cavity 203 enables the housing 200 to have a bass tube structure, thereby reducing the resonance frequency of the whole speaker assembly, emitting sound of lower frequencies, and improving the sound quality.

By providing the extended cavity 203 on one side of the corresponding cavity 202, the extended cavity 203 can serve as a bass tube disposed in the corresponding cavity 202, thereby reducing the resonant frequency of the speaker assembly and facilitating the emission of lower frequency sound. In this embodiment, the extension cavity 203 and the corresponding cavity 202 together form a linear channel, so that the housing 200 is convenient to manufacture and the occupied space is reduced.

Further, as shown in fig. 1, a spacer 300 is disposed in the extension cavity 203, the spacer 300 extends along a direction from the corresponding cavity 202 to the extension cavity 203, and divides the extension cavity 203 into a first extension sub-cavity 2031 and a second extension sub-cavity 2032, a communication hole 310 is disposed on the spacer 300, and the communication hole 310 communicates the first extension sub-cavity 2031 and the second extension sub-cavity 2032.
