Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0036] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the figure). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0037] In addition, the descriptions in...

Abstract

The invention discloses a sound production device and wearable equipment. The sound production device comprises a vibration system and a magnetic circuit system, the vibration system comprises a flatvoice coil. The magnetic circuit system comprises a magnet assembly and a magnetic conduction assembly. The voice coil is inserted into a magnetic gap formed by the magnetic circuit system. The magnetization direction of the magnet assembly and the vibration direction of the voice coil are parallel to the vertical direction of the sound production device. The magnet assembly comprises an upper magnet unit and a lower magnet unit, the magnetic conductive assembly comprises a first magnetic conductive plate and a second magnetic conductive plate which are arranged corresponding to the long axisof the voice coil, the first magnetic conductive plate is located between the upper magnet unit and the lower magnet unit, and the second magnetic conductive plate is located at the end, away from thefirst magnetic conductive plate, of the upper magnet unit. According to the sound production device, the space is saved, the vibration area of the dome piece can be increased through the vertically-arranged folding ring piece, and the acoustic performance of the sound production device is improved.

Description

technical field [0001] The invention relates to the technical field of electroacoustic conversion, in particular to a sound generating device and a wearable device. Background technique [0002] With the rapid development of the consumer electronics industry, there is also a strong demand for various smart wearable terminals, such as smart glasses, which not only have the functions of traditional glasses, but also have many entertainment functions. For example, smart glasses can have a built-in Bluetooth system to realize the function of a Bluetooth headset, and can be connected to a mobile phone for use, and the smart glasses can be used to answer calls or play music stored in the mobile phone. In modern speaker technology, the acoustic performance of a dynamic speaker is directly related to its size. The larger the size, the better the acoustic effect, and the smaller the size, the worse the acoustic effect. Due to the consideration of portability, comfort and aesthetics,...
