Embodiment Construction

[0030] 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.

[0031] 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.

[0032] In addition, the descriptions in...

Abstract

The invention discloses a sound production module, which comprises a flexible deformation piece, a shell with an accommodating space and a bass tuning cavity, and a magnetic circuit system, a high pitch vibration system and a bass vibration system which are arranged in the accommodating space, and is characterized in that the magnetic circuit system comprises a sealing piece, a magnetic steel assembly and a first washer attached to the magnetic steel assembly; a high-pitch rear cavity is formed between the high pitch vibration system and the magnetic circuit system; a bass rear cavity communicated with the bass tuning cavity is formed between the bass vibration system and the magnetic circuit system, the first washer protrudes towards the bass vibration system to form a high pitch tuning cavity with an opening facing the bass vibration system, the sealing piece blocks the opening, and the first washer is provided with a through hole communicated with the high pitch tuning cavity and the high pitch rear cavity. The bass tuning cavity is internally provided with a first sound absorbing material, and / or the shell is also provided with a mounting hole for communicating the outside withthe bass tuning cavity, and the sound production module also comprises a flexible deformation piece for blocking the mounting hole. The sound production module disclosed by the invention is small insize and wide in audio frequency bandwidth.

Description

technical field [0001] The invention relates to the technical field of electroacoustic conversion, in particular to a sounding module. Background technique [0002] In order to achieve a perfect sound effect, the speakers of some existing electronic equipment combine the bass unit and the tweeter unit, so that the low-frequency part and the high-frequency part of the audio can be fully and perfectly presented, and the bandwidth can be fully expanded. [0003] However, combining the woofer and tweeter into one sound module will inevitably lead to a larger size of the sound module than that of a single vibration unit, which does not meet the requirements for thinning the product. [0004] Therefore, it is necessary to provide a novel sounding module to solve the above technical problems. Contents of the invention [0005] The main purpose of the present invention is to provide a sounding module, aiming at solving the technical problem of large size of the sounding module ha...
