Embodiment 1
[0049] like image 3 As shown, an acoustic device 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 moving coil 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.
[0050] 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 waves on the back...
Embodiment 2
[0073] like Figure 7 As shown, the main difference between this embodiment and Embodiment 1 is that the flexible deformation part 22 in this embodiment is an independent installation part, and a through hole is provided on the isolation part (not marked), and the flexible deformation part 22 is installed on On the through hole, specifically, the flexible deformation portion 22 is fixedly connected to the first casing part around the through hole by bonding, welding or thermal fusion. This improved design is more convenient in the material selection of the flexible deformation part 22, and can achieve a more realistic combination with the first housing. At the same time, providing through holes on the first housing can simplify the realization of product technology.
Embodiment 3
[0075] The main difference between this embodiment and the above-mentioned embodiments is that the acoustic device in this embodiment is provided with a sound channel, and the sound channel corresponds to the design of the sound outlet 4, and the sound wave on the front side of the vibrating diaphragm 11 is radiated to the Sound outlet 4. This design is more in line with the design requirements of some terminal products, and will not occupy the space of the panel of the mobile phone, which is conducive to the design of the full screen, while avoiding the occlusion and interference of other components.
[0076] Specifically, such as Figure 8 As shown, the sound unit 1 is installed in the first casing 2, and the sound output channel is also arranged on the first casing 2. In other embodiments, it is also possible that the sound output channel is arranged on the second housing 3, and the sound output component is docked with the sound output channel; or, the sound output channe...
