Embodiment Construction

[0070] 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.

[0071] 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 accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0072] In addition, the ...

Abstract

The invention discloses a sound-generating device, which includes a first vibration system, a second vibration system, and a magnetic circuit system. The first vibration system includes a first diaphragm and a voice coil disposed on the side of the first diaphragm facing the magnetic circuit system. The second vibration system includes a second diaphragm opposite to the first diaphragm, a reinforcing part is combined at the middle position of the second diaphragm, and an extension part extending toward the direction close to the first diaphragm is provided on the reinforcing part, An avoidance part is provided at a position corresponding to the extension part on the magnetic circuit system, and the extension part can pass through the avoidance part and be fixed to the first diaphragm. The sound generating device provided by the present invention is equipped with two sets of vibration systems, but only one set of voice coil and magnetic circuit system is used to realize the two-way synchronous sounding structure, which occupies a small volume and is convenient to be widely used in portable terminals.

Description

technical field [0001] The invention relates to the field of electroacoustic technology, in particular to a sound generating device and a portable terminal. Background technique [0002] At present, the sound generating device has been widely used as an important part of a terminal with an audio playback function. Some terminals, especially portable terminals, such as mobile phones, tablet computers, and earphones can provide very limited installation space for sound-generating devices. Therefore, existing sound-generating devices that can be applied to narrow installation spaces usually use a single diaphragm front-facing sounding structure . In order to realize two-way sounding, the prior art provides a sounding device using two sets of voice coils and a magnetic circuit system, but such a sounding device is usually bulky and difficult to be widely used. Contents of the invention [0003] The main purpose of the present invention is to provide a sounding device, aiming...
