Title
(EN) Sound production device
(ZH) 发声器件
Abstract
(EN) The utility model provides a sound production device, which comprises a shell with an accommodating space and a sound production monomer, the sound production monomer comprises a basin stand, a vibration system and a magnetic circuit system, the vibration system comprises a vibrating diaphragm fixed on the basin stand, the shell comprises a rear shell plate, a side wall and a fixed step, and the side wall surrounds the peripheral side of the basin stand; one end of the sounding monomer right facing the rear shell plate is fixedly connected with the fixed step; the thickness of the shell is smaller than that of the basin stand; the side wall is attached to the basin frame, or a gap is formed between the side wall and at least one side of the basin frame, and the gap is smaller than three times of the thickness of the shell; the rear shell plate, the side wall and the sound production single body jointly define a rear sound cavity, the sound production single body is provided with a leakage part communicated with the rear sound cavity, the shell is provided with a leakage hole penetrating through the shell, and the leakage hole communicates the rear sound cavity with the outside. Compared with the prior art, the sounding device is simple in structure, excellent in acoustic performance and good in user experience effect, and the sounding single body is not easy to fall off.
(ZH) 本实用新型提供了一种发声器件,其包括具有收容空间的壳体和发声单体,发声单体包括盆架、振动系统和磁路系统,振动系统包括固定于盆架的振膜,壳体包括后壳板、侧壁和固定台阶,侧壁环绕盆架周侧,发声单体正对后壳板的一端与固定台阶固定连接;壳体的厚度小于盆架的厚度;侧壁贴合于盆架,或侧壁与盆架的至少一侧设有间隔,且该间隔小于3倍壳体的厚度;后壳板、侧壁及发声单体共同围成后声腔,发声单体设有与后声腔连通的泄露部,壳体设有贯穿其上的泄露孔,泄露孔将后声腔与外界连通。与相关技术相比,本实用新型的发声器件结构简单、声学性能优、用户体验效果好,且发声单体不易跌落。
