Problems solved by technology

However, the air-conduction sound transmission method requires a larger volume of acoustic devices and structures, and at the same time causes more obvious sound leakage
The bone conduction sound transmission method will produce strong low-frequency vibration, and often cause a certain amount of leakage sound
These problems have a negative impact on the experience of this open-ear listening method, which limits the application of this method

Abstract

The invention discloses a sound output device. The sound output device includes: a vibration speaker configured to generate a bone conduction sound wave; and an air conduction loudspeaker configured to generate air conduction sound waves, wherein the sound output device is configured to output sound waves in a target frequency range, the bone conduction sound waves comprise a high frequency part of the target frequency range, and the air conduction sound waves comprise a low frequency part of the target frequency range.

Description

technical field [0001] The present application relates to the field of acoustics, in particular to a sound output device. Background technique [0002] Today, wearable devices with acoustic output functions are emerging and popular. In particular, a listening method with the ears open (that is, without the need to plug or cover the ears with acoustic devices) is increasingly being used in wearable devices because of its health and safety features. This open-ear listening method can be realized through air conduction or bone conduction. However, the air conduction sound transmission method requires a larger volume of acoustic devices and structures, and at the same time causes more obvious external sound leakage. The bone conduction sound transmission method will produce strong low-frequency vibrations, and often cause certain leakage sounds. These problems all have a bad influence on the experience of this open-ear listening method, and limit the application of this metho...
