Abstract

The present disclosure discloses an acoustic input and output apparatus. The acoustic input and output apparatus may include a loudspeaker assembly, a sound-pickup assembly configured to pick up a sound signal, and a connection assembly including an elastic member, wherein a first end of the elastic member may connect to the loudspeaker assembly, and a second end of the elastic member may connect to the sound-pickup assembly. The elastic member may be configured to cause an average amplitude attenuation rate of vibrations within a phonic frequency band generated by the loudspeaker assembly to be larger than or equal to 35% in a process that the vibration transmits from the first end of the elastic member to the second end of the elastic member.

First claim

What is claimed is:

1. An acoustic input and output apparatus, comprising:
a loudspeaker assembly, the loudspeaker assembly including a first loudspeaker housing, a second loudspeaker housing, and a loudspeaker,
wherein the first loudspeaker housing is matched and connected to the second loudspeaker housing to form a containment space for accommodating the loudspeaker, a first through-hole and a second through-hole are arranged on the first loudspeaker housing at an interval, and the first through-hole and second through-hole are in communication with the containment space;
a sound-pickup assembly configured to pick up a sound signal;
a wiring group of the sound-pickup assembly traverses the first through-hole, the containment space, and the second through-hole; and
a connection assembly including, an elastic member, a first end of the elastic member connecting to the loudspeaker assembly, and a second end of the elastic member connecting to the sound-pickup assembly,
wherein the elastic member is configured to cause an average amplitude attenuation rate of vibrations within a phonic frequency band generated by the loudspeaker assembly to be larger than or equal to 35% in a process that the vibrations transmit from the first end of the elastic member to the second end of the elastic member.

2. The acoustic input and output apparatus of claim 1 , wherein the loudspeaker assembly further includes a wire-fixing assembly configured to fix the wiring group of the sound-pickup assembly passing through the first through-hole and reaching the second through-hole.

3. The acoustic input and output apparatus of claim 2 , wherein the wire-fixing assembly includes press-holding members arranged in the containment space, and the press-holding members are configured to contact the wiring group of the sound-pickup assembly to reduce a vibration amplitude of the wiring group of the sound-pickup assembly.

4. The acoustic input and output apparatus of claim 1 , wherein
the first loudspeaker housing includes a bottom wall and a side wall connecting with each other, and the side wall surrounds and connects with the bottom wall;
the second loudspeaker housing is arranged covering one side of the side wall away from the bottom wall to form the containment space; and

the first through-hole is formed on the bottom wall, and the second through-hole is formed on the sidewall.

5. The acoustic input and output apparatus of claim 1 , wherein the sound-pickup assembly is rotatable relative to the loudspeaker assembly.

6. The acoustic input and output apparatus of claim 5 , wherein the connection assembly further includes a rotation member matched and connected to the first through-hole rotatably, and the sound-pickup assembly is connected with the rotation member so as to rotate relative to the first loudspeaker housing.

7. The acoustic input and output apparatus of claim 6 , wherein
the rotation member includes a wire-guiding part and a rotation part connecting with each other;
the rotation part is inserted in the first through-hole; and
the sound-pickup assembly is connected with the wire-guiding part to enable the wiring group of the sound-pickup assembly to pass through the wire-guiding part and enter the first through-hole via the rotation part.

8. The acoustic input and output apparatus of claim 7 , wherein
a damping groove is arranged along a circumferential direction of the rotation part;
the connection assembly further includes a damping member arranged in the damping groove; and
the damping member contacts an inner wall of the first through-hole to provide a rotational damping for the rotation part via contact friction.

9. The acoustic input and output apparatus of claim 8 , wherein
the rotation part includes a rotation main body, and a first stopping part and a second stopping part protruding from two ends of the rotation main body along radial directions of the rotation main body, respectively;
the rotation main body is inserted into the first through-hole;
the first stopping part and the second stopping part abut against two sides of the first loudspeaker housing, respectively, to restrict a movement of the rotation part relative to the first loudspeaker housing along an axial direction; and
the damping groove is formed between the first stopping part and the second stopping part.

10. The acoustic input and output apparatus of claim 7 , wherein the connection member further includes a rotation-limiting structure configured to restrict a rotation range of the rotation part relative to the first loudspeaker housing.

11. The acoustic input and output apparatus of claim 10 , wherein
the rotation-limiting structure includes a limiting groove arranged at an upper portion of the rotation part along a circumferential direction, and a limiting member arranged on the inner wall of the first through-hole and matched to the limiting groove; and
the limiting member abuts against two ends of the limiting groove, when the rotation part rotates relative to the first loudspeaker housing, to restrict the rotation part from rotating.

12. The acoustic input and output apparatus of claim 11 , wherein the limiting groove is arranged as an open-loop.

13. The acoustic input and output apparatus of claim 12 , wherein the rotation range of the rotation part is 0˜270 degrees.

14. The acoustic input and output apparatus of claim 7 , wherein
the wire-guiding part is configured with a first hole segment, the rotation part is arranged with a second hole segment, and the first hole segment communicates with the second hole segment;
the sound-pickup assembly is matched and connected to the first hole segment; and
the wiring group of the sound-pickup assembly traverses the first hole segment and reaches the first through-hole via the second hole segment.

15. The acoustic input and output apparatus of claim 14 , wherein the loudspeaker assembly further includes a fixing member configured to restrict a movement of the sound-pickup assembly relative to the rotation member.

16. The acoustic input and output apparatus of claim 15 , wherein the fixing member includes a fixing main body inserted into the second hole segment, and matched and connected to the first end of the elastic member to restrict the movement of the elastic member relative to the rotation member.

17. The acoustic input and output apparatus of claim 16 , wherein
the fixing member further includes a fixedly connection part arranged on one end of the fixing main body, and the first end of the elastic member is configured with a fixedly adaptive connection part; and
the fixedly connection part is able to be matched and connected with the fixedly adaptive part.

18. The acoustic input and output apparatus of claim 16 , wherein
gaps are formed at one end of the rotation part away from the wire-guiding part, and the gaps communicate with the second hole segment; and
