Sound production device

Abstract

The invention provides a sound production device, which comprises a vibrating diaphragm and a shell, the shell comprises a first sound guide hole and a second sound guide hole, the vibrating diaphragm is arranged in the shell, and the first sound guide hole and the second sound guide hole are respectively positioned at two sides of the vibrating diaphragm; when a user wears the sound production device, the distance between the first sound guide hole and the ear canal opening of the user is smaller than the distance between the vibrating diaphragm and the ear canal opening of the user, and the included angle between the connecting line of the first sound guide hole and the second sound guide hole and the connecting line of the mass center of the vibrating diaphragm and the ear canal opening of the user is smaller than 45 degrees. The distance between the second sound guide hole and the ear canal opening of the user is larger than the distance between the vibrating diaphragm and the ear canal opening of the user. When a user wears the sounding device, and the included angle between the connecting line of the first sound guide hole and the second sound guide hole and the connecting line of the mass center of the vibrating diaphragm and the ear canal opening of the user is smaller than 45 degrees, the listening volume when the user wears the sounding device can be increased, the far-field leakage volume can be reduced, meanwhile, the sounding device does not interfere with the ears of the user, and the wearing experience of the user is improved.

Description

[0001] priority information [0002] This application claims priority from International Application No. PCT / CN2020 / 140815, filed on December 29, 2020, the entire contents of which are incorporated herein by reference. technical field [0003] The present application relates to the technical field of audio equipment, and in particular, to a sound producing device. Background technique [0004] Compared with traditional in-ear headphones, open-back audio equipment has the advantages of non-blocking, safety, and comfort. Combining open audio devices with wearable devices (eg, glasses, VR), on the one hand, the structure of the wearable device (eg, glasses legs) can be used as the structural attachment and support of the audio device; on the other hand, the audio device can make up for wearing The singularity of functions of traditional wearable devices. For example, audio equipment can be combined with wearable equipment used in special scenarios (for example, glasses for cy...

AI Technical Summary

Problems solved by technology

The combination of audio equipment and wearable equipment will increase the weight of the wearable equipment, and the interference between the audio equipment and the ear will also affect the user's wearing experience

Due to the influence of the structure of the human ear, the audio device is placed directly near the user's ear. The sound emitted by the open audio device is affected by the tragus, and the sound cannot be transmitted to the user's eardrum, which affects the user's listening volume to a certain extent.
