Problems solved by technology

Because the driving energy of the robot in the prior art is generally driven by batteries, the limited energy cannot support the use of high-power speakers, and the space inside the robot is limited and it is impossible to install speakers with better sound quality and larger space.
Therefore, the sound quality of the sound system used by the robot in the prior art is relatively poor, and the special bass effect is almost completely absent, and the stereoscopic effect of the music sent by the sound system is very insufficient.

Embodiment 1

[0048] see figure 1 , figure 1 It is a structural schematic diagram of the robot sound system according to the embodiment of the present invention.

[0049] Such as figure 1 As shown, a robot audio system includes: a resonant cavity unit 200 , a speaker unit 300 and a passive diaphragm unit 400 . Wherein, the resonant sound cavity unit 200 is arranged inside the shell 100 of the robot, and the internal structure of the resonant sound cavity unit 200 is a closed cavity structure; The corresponding mechanical vibration drives the gas density in the resonant sound cavity unit 200 to change, and at least part of the structure of the speaker unit 300 is exposed on the surface of the housing 100; the passive diaphragm unit 400 is sealed and connected to the surface of the resonant sound cavity unit 200, and the The change of gas density in the cavity unit 200 generates mechanical vibration of the same frequency as the speaker unit 300 , and at least part of the structure of the p...

Embodiment 2

[0083] A robot, the robot includes a sound system, the sound system includes a robot sound, and the robot sound is the robot sound mentioned in Embodiment 1.

[0084] For robots using audio, a resonant sound cavity unit is arranged inside the robot shell, and a speaker unit and a passive diaphragm unit are arranged on the resonant sound cavity unit. The resonant sound cavity unit is constructed into a sealed structure. When the speaker unit generates mechanical vibration, it can Drive the air inside the resonant sound cavity unit to fluctuate. Since the resonant sound cavity unit is a sealed structure, the gas fluctuation inside it will directly act on the passive diaphragm unit, which will cause the passive diaphragm unit to produce mechanical vibration of the same frequency. The mechanical vibration of the diaphragm unit causes the surrounding gas to fluctuate and then generate sound waves with the same frequency as the mechanical frequency. Therefore, the passive diaphragm u...

Abstract

The embodiment of the invention discloses a robot sound and a robot. The robot sound comprises a resonant sound cavity unit, a loudspeaker unit and a passive vibrating diaphragm unit. The resonant sound cavity unit is arranged in a shell of the robot, and the interior of the resonant sound cavity unit is constructed into a closed cavity structure; the loudspeaker unit is hermetically connected to the surface of the resonant sound cavity unit and generates corresponding mechanical vibration with the change of applied current to drive the change of the air density in the resonant sound cavity unit, and at least a part of the structure of the loudspeaker unit is exposed from the surface of the shell; and the passive vibrating diaphragm unit is hermetically connected to the surface of the resonant sound cavity unit and generates mechanical vibration having the same frequency as the loudspeaker unit with the change of the air density in the resonant sound cavity unit, and at least a part of the structure of the passive vibrating diaphragm unit is exposed from the surface of the shell. The loudspeaker unit and the passive vibrating diaphragm unit are placed at different positions of the resonant sound cavity unit, so that the stereoscopic effect of the robot sound can be reinforced.

Description

technical field [0001] Embodiments of the present invention relate to the field of heat conduction, in particular to a robot audio system and a robot. Background technique [0002] With the development of mobile communication, computer and Internet technology, intelligent robots are widely used in the fields of education, scientific research or security due to their small size and strong processing capabilities, and are recognized by users. The most important function of the robot in the prior art is to communicate with users through voice, including accepting user instructions through voice, and communicating with users through voice, such as singing, telling stories, chatting or imparting professional knowledge. As robots become more and more intelligent, the functions of their voice systems are becoming more and more important. Therefore, the requirements for the robot's sound system are getting higher and higher. [0003] In the prior art, the sound system used by the r...
