Embodiment

[0036] like Figure 1-4 As shown, the sound generator module provided by the invention includes a module housing and a sound generator unit 10 located in the module housing. The module housing includes a module upper housing 1 and a module lower housing 2, and the sound generator unit 20 is installed and fixed in the module housing. Among them, the sound generator unit 20 includes a vibration system and a magnetic circuit system. The vibration system includes a diaphragm 101 and a voice coil combined with the lower side of the diaphragm 101. The magnetic circuit system is provided with a magnetic gap corresponding to the voice coil, and the voice coil is based on the input audio frequency. The electrical signal moves up and down in the magnetic gap, and the diaphragm 101 vibrates with the up and down movement of the voice coil, instigating the air to emit sound, thereby completing the energy conversion between electro-acoustic sounds.

[0037] It is only shown here that the m...

Abstract

A sounder module disclosed by the present invention comprises a module shell and a sounder monomer located in the module shell, a vibrating diaphragm of the sounder monomer divides the space in the sounder module into a front vocal cavity and a rear vocal cavity, and the sounder module is provided with a main sound outlet hole communicated with the front vocal cavity. The main sound outlet hole is formed in the side surface of the front sound cavity and is positioned on one side of the short axis of the sounder single body; the distance from the central position of the sounder single body to the opposite side wall surface of the main sound outlet hole is not less than 8.5 mm; an acoustic component for resonance sound absorption is arranged in the sounder module, the acoustic component is provided with a communicating hole in the side wall surface opposite to the main sound outlet hole, and the acoustic component is communicated with the front sound cavity through the communicating hole. By using the sounder module as a sounding device, standing trough points influencing the flatness of a sensitivity curve are eliminated, and the medium-high frequency tone quality is improved.

Description

technical field [0001] The invention belongs to the technical field of electro-acoustic transduction, and more particularly, relates to a sound generator module and an intelligent head-mounted device. Background technique [0002] In recent years, smart head-mounted devices such as VR and AR have developed rapidly. As an important sound-emitting device, the sound generator module has been continuously improved in structure to meet the high-fidelity sound quality performance of smart head-mounted devices that can reproduce various sound effects realistically. . [0003] The sound generator module is an energy conversion device used to complete the conversion between electrical signals and acoustic signals. In the existing sound generator module, especially for the module with side sound outlet, the sound outlet channel of the front sound cavity is generally long. Taking smart glasses as an example, in order to save product space, the sound generator module is usually set in...
