Description

TECHNICAL FIELD [01] The present invention patent generally relates to the technical field of electronic equipment and, in particular, to an acoustic device. BACKGROUND OF THE INVENTION [02] Bone conduction headphones can convert sound into mechanical vibrations with different frequencies and transmit these vibrations to the auditory nerve using human bones/tissues as a medium. Thus, the user can hear sound without using the external auditory canal and the tympanic membrane of the ear. For a user with hearing loss (e.g., a user with normal hearing in one ear and hearing loss in the other), due to their hearing being damaged or degraded, a bone conduction headphone with higher acoustic performance (e.g., with better sound pickup effect) and a better functional structure (e.g., having a volume control function that corresponds to their hearing conditions) is necessary. Therefore, it is desirable to provide an acoustic device with higher acoustic performance and a better functional structure to meet the needs of users. SUMMARY [03] According to one aspect of the present invention, an acoustic device is provided. The acoustic device may include a receptacle having an accommodation space and one or more communication holes. Each communication hole connects the accommodation space and an exterior space. One or more sound pickup assemblies are arranged in the accommodation space and configured to capture sound through the communication hole, and one or more channel assemblies are arranged in the accommodation space, wherein at least one of the one or more channel assemblies is arranged between a sound pickup element in one or more sound pickup assemblies and a communication hole in one or more communication holes, so that sound is transmitted to the sound pickup element through at least one of the one or more channel assemblies after passing through the communication hole. [04] In some embodiments, at least one of the one or more channel sets includes a first hole, a channel and a second hole. The first hole is in top communication with the communication hole. The second hole is arranged adjacent to the sound pickup assembly so that the sound is transmitted to the sound pickup assembly through the communication hole, the first hole, the channel and the second hole in sequence. [05] In some embodiments, an accommodation slot is provided in the accommodation space to accommodate at least one of the one or more sound pickup sets. At least one of the channel sets presses against at least one of the sound pickup sets in the accommodation slot. [06] In some embodiments, the receptacle may include a first receptacle and a second receptacle, and the first receptacle and the second receptacle are combined and connected to form the accommodation space. The second receptacle includes a bottom wall and a side wall surrounded around the bottom wall; the first receptacle is physically connected to the side wall to form the accommodation space and the bottom wall projects towards one side of the first receptacle and is provided with a flange around the accommodation groove, at least one channel assembly is covered in the flange to hold the sound pickup assembly in the accommodation groove. [07] In some embodiments, the channel may include an upper channel wall, a lower channel wall and a side channel wall, the upper channel wall and the lower channel wall being located respectively at two ends of the side channel wall. The first hole is disposed in the side channel wall or the upper channel wall. The second hole is disposed in the lower channel wall; and the lower channel wall is configured to press and hold the sound pickup assembly. [08] In some embodiments, the sound pickup assemblies may comprise a sound pickup element and a protective cover, the protective cover being fitted to the outer periphery of the sound pickup element. The protective cover is provided with a groove facing the lower wall of the channel. The sound pickup element is at least partially located in the groove; and the protective cover rests against and fits into the flange. [09] In some embodiments, a canal length in a direction connecting the upper canal wall and the lower canal wall is in the range of 0.45-0.75 mm. [010] In some embodiments, the distance from the first orifice to the second orifice along the canal is greater than or equal to 4 mm. [011] In some forms, the first orifice may have the same shape as the communication orifice. [012] In some embodiments, the acoustic device may also comprise a protective component, which is provided between at least one channel set and the receptacle to space the communication hole and the first hole. [013] In some embodiments, the protection component may include a first mesh and a second mesh arranged in layers, with the second mesh being closer to at least one set of channels than the first mesh. [014] In some embodiments, the acoustic device may also include multiple loudspeaker sets, a control circuit set
