Embodiment 1
[0050] Such as Figure 3A-Figure 4 As shown, an acoustic device 100 includes a sounding unit 1, wherein, in this embodiment, the sounding unit 1 is a miniature sounding unit, more specifically, the sounding unit 1 is a miniature dynamic speaker. The sound unit 1 generally includes a housing and a vibration system and a magnetic circuit system fixed in the housing. The vibration system includes a vibrating diaphragm 11 fixed on the housing and a voice coil combined with the vibrating diaphragm 11. The magnetic circuit system is formed with The magnetic gap, the voice coil is set in the magnetic gap, and the voice coil reciprocates up and down in the magnetic field after being fed with alternating current, thereby driving the vibrating diaphragm 11 to vibrate and produce sound.
[0051] The acoustic device is provided with a sound outlet 4, and the sound waves on the front side of the vibrating membrane 11 are radiated to the outside through the sound outlet 4, and the sound wav...
Embodiment 2
[0090] The main difference between this embodiment and the above-mentioned embodiments is that in this embodiment, a plurality of sounding units 1 and first airtight chambers 21 are provided in one-to-one correspondence, and a second airtight chamber 31 is provided, and each of the first airtight chambers A flexible deformation part 22 and a protective cover 27 are provided on the cavity wall of the cavity 21 . Specifically, the acoustic device in this embodiment includes two sounding units 1, and two first airtight cavities 21 are respectively designed correspondingly, the second airtight chamber 31 is one, and the cavity walls of the two first airtight cavities 21 A flexible deformation part 22 and a protective cover 27 are respectively designed. This design can facilitate the application in the case of an acoustic device or system that requires multiple sounding units 1 , such as stereophonic or array design requirements.
[0091] In another embodiment, on the cavity wall ...
Embodiment 3
[0093] This embodiment discloses an electronic device 5, such as Figure 7As shown, the acoustic device 100 in the above embodiment is installed on the electronic device 5, which may be a mobile phone, a tablet computer, a notebook, and the like.
[0094] The electronic device 5 specifically includes a casing of the electronic device, and at least a part of the casing of the electronic device is used to form the first airtight cavity 21 and / or the second airtight cavity 31 of the acoustic device. That is, part or all of the cavity wall of the first closed cavity 21 is formed by the casing of the electronic device, or part or all of the cavity wall of the second closed cavity 31 is formed by the casing of the electronic device, or, Part or all of the cavity walls of the first sealed cavity 21 and the second sealed cavity 31 are formed by the casing of the electronic device. In the present invention, the casing of the electronic device doubles as the cavity wall of the first ai...
