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 voice production device. The voice production device comprises a first vibration system, a second vibration system and a magnetic path system; the first vibration system includes a first vibration diaphragm as well as a voice coil arranged at one side, facing to the magnetic path system, of the first vibration diaphragm; the second vibration system includes a second vibration diaphragm arranged opposite to the first vibration diaphragm; a reinforcing portion is bonded at a middle position of the second vibration diaphragm; an extension portion extending toward a direction close to the first vibration diaphragm is arranged on the reinforcing portion; a position, corresponding to the extension portion, on the magnetic path system is provided with an avoidance portion; and the extension portion can pass through the avoidance portion and is fixed to the first vibration diaphragm. The voice production device provided by the invention is provided with two sets of vibration systems, but only a set of voice coil and magnetic path system is adopted to implement bidirectional synchronous voice production, so the structural occupied size is small and the voice production device is convenient to be widely applied to a portable terminal.

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...
