The utility model discloses a vibration isolation structure of headphone, which comprises a hollow shell, which comprises a front shell and a rear shell fastened together. The front shell and the rear shell are surrounded by a rear cavity, and a horn unit is arranged in the rear cavity. The characteristics of the structure are that there is a vibration isolation structure between the horn unit and the shell. The vibration isolation structure includes a ring-shaped spring support, and the inner hole of the spring support plate is fixed on the horn single. On the element, the periphery of the spring branch is fixed on the shell. Spring bracket has elasticity and can buffer the vibration brought by the earphone shell. Even if the vibration is large, the spring bracket can also attenuate the vibration effectively. Therefore, when the loudspeaker unit sounds and produces vibration, the spring bracket can play a role of vibration isolation, making the natural frequency of the earphone system outside the working frequency range of the earphone, in order to avoid the occurrence of resonance phenomenon of the earphone shell, the horn unit. In low frequency, the vibration energy transmitted to the earphone shell is greatly reduced, which will not consume the low frequency energy of the earphone and ensure the bass effect of the earphone.
【技术实现步骤摘要】
头戴式耳机的隔振结构
本技术涉及耳机
,具体的说,涉及一种头戴式耳机的隔振结构。
技术介绍
目前,市面上的绝大多数头戴耳机为动圈式耳机,即音圈推动振膜振动发出声音。因为固体都有自己的共振频率,当振膜工作在耳机壳体的固有频率点时就会引起壳体共振,从而消耗耳机的低频能量,使耳机低音效果变差。
技术实现思路
针对上述不足,本技术所要解决的技术问题是:提供一头戴式耳机的隔振结构,通过合理设计隔振结构,将耳机系统的固有频率设计在耳机工作频率范围之外,以避免耳机壳体共振现象的发生。为解决上述技术问题,本技术的技术方案是:一种头戴式耳机的隔振结构,包括:中空的壳体,所述壳体包括扣合在一起的前壳和后壳,所述前壳与所述后壳围成后腔,所述后腔内设置有喇叭单元,其特征在于,所述喇叭单元与所述壳体之间设有隔振结构,所述隔振结构包括圆环形的弹簧支片,所述弹簧支片的内孔固定于所述喇叭单元上,所述弹簧支片的外周固定于所述壳体上。优选的,所述弹簧支片包括间隔设置的前弹簧支片和后弹簧支片。优选的,所述喇叭单元安装于所述前壳上,所述弹簧支片的外周与所述前壳固定。优选的,所述前壳设有圆筒形的安装部,所述 ...
