Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] Such as Figure 1-8 as shown, figure 1 It is an exploded schematic view of a bone conduction speaker 100 according to an exemplary embodiment. Such as figure 1 As shown, the bone conduction speaker 100 may include a speaker body 1 , a vibration sound transmission layer 2 and a vibration damping layer 3 . Wherein, the speaker body 1 can generate vibration based on the change of the magnetic field in the speaker body 1, and the vibration sound transmission layer 2 is in contact with a part of the speaker body 1, so that the vibration generated on the speaker body 1 can be carried out through the vibration sound transmission layer 2. transfer. and, if figure 2 As shown, when the bone conduction speaker 100 is equipped with smart wearable glasses 200, the vibrating sound-conducting layer 2 is in contact with the user, thereby transmitting the v...

Abstract

The invention relates to a bone conduction loudspeaker. The bone conduction loudspeaker comprises: a loudspeaker body, wherein the loudspeaker body is used for generating vibration; a vibration soundtransmission layer, in contact with a part of area of the loudspeaker body and used for transmitting vibration generated by the loudspeaker body; and a vibration damping layer, wrapping other areas, except for a part of the area in contact with the vibration sound transmission layer, on the loudspeaker body. The bone conduction loudspeaker is arranged in the intelligent wearable equipment and is in direct contact with the body of a user; the resonance processing method comprises the step of filtering the audio signal in the preset frequency range or adjusting the gain of the audio signal in the preset frequency range. According to the invention, sound leakage of the bone conduction loudspeaker can be prevented, the sound leakage problem of the bone conduction loudspeaker in related technologies is improved, the privacy of a user is protected, and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of terminal technology, in particular to a bone conduction speaker, a smart wearable device using the bone conduction speaker, and a processing method for resonance generated by the bone conduction speaker in the device. Background technique [0002] There are two ways of sound transmission: one is through air vibration; the other is through direct vibration. Bone conduction speakers transmit sound by directly vibrating human bone or skin tissue, and its working principle is to convert electrical signals into mechanical vibration signals, and mechanical vibration transmits sound through human bone or skin tissue. In the related art, the vibration generated by the bone conduction speaker vibrates and transmits sound from various directions, resulting in inconcentrated sound and leakage of sound, which easily leaks user privacy. Contents of the invention [0003] The present application provides a bone conduc...
