Abstract

This present disclosure provides an acoustic device. The acoustic device includes a housing, one or more sound pickup assemblies, and one or more channel assemblies. The housing has an accommodating space and one or more communication holes. Each communication hole communicates the accommodating space and an outside space. The one or more sound pickup assemblies may be disposed in the accommodating space for picking up a sound through the communication holes. The one or more channel assemblies may be disposed in the accommodating space. At least one of the one or more channel assemblies is disposed between one sound pickup assembly of the one or more pickup assemblies and one communication hole of the one or more communication holes, so that the sound is transmitted to the sound pickup assembly through the at least one of the one or more channel assemblies after passing through the communication hole.

Claims (42)

1. An acoustic device comprising:

a housing having an accommodating space and one or more communication holes, each communication hole communicating the accommodating space and an outside space;

one or more sound pickup assemblies disposed in the accommodating space and configured to pick up a sound through the one or more communication holes;

one or more channel assemblies disposed in the accommodating space, wherein at least one of the one or more channel assemblies is disposed between one sound pickup assembly of the one or more pickup sound assemblies and one communication hole of the one or more communication holes, so that the sound is transmitted to the sound pickup assembly through the at least one of the one or more channel assemblies after passing through the communication hole;

multiple speaker assemblies;

a control circuit assembly comprising multiple control elements, wherein each control element corresponds to at least one speaker assembly of the multiple speaker assemblies, and the at least one of the one or more communication holes is disposed on a side of the housing away from the at least one speaker assembly of the multiple speaker assemblies; and

multiple interactive assemblies, wherein each interactive assembly corresponds to one of the multiple speaker assemblies and the corresponding control element of the speaker assembly, the interactive assembly is configured to trigger the control element corresponding to the interactive assembly to control the corresponding speaker assembly to implement a function corresponding to a user operation instruction in response to receiving the user operation instruction.

2. The acoustic device of claim 1 , wherein the at least one of the one or more channel assemblies includes a first hole, a channel, and a second hole, the first hole is in butt communication with the communication hole, the second hole is disposed adjacent to the sound pickup assembly so that the sound is transmitted to the sound pickup assembly through the communication hole, the first hole, the channel, and the second hole in sequence.

3. The acoustic device of claim 2 , wherein an accommodating groove is disposed in the accommodating space for accommodating at least one of the one or more sound pickup assemblies, the at least one of the one or more channel assemblies presses the at least one of the one or more sound pickup assemblies in the accommodating groove.

4. The acoustic device of claim 3 , wherein

the housing includes a first housing and a second housing, and the first housing and the second housing are matched and connected to form the accommodating space;

the second housing includes a bottom wall and a side wall ringed around the bottom wall;

the first housing is physically connected to the side wall to form the accommodating space; and

the bottom wall protrudes toward one side of the first housing and is provided with a flange surrounding the accommodating groove, the at least one of the one or more channel assemblies is covered on the flange to hold the sound pickup assembly in the accommodating groove.

5. The acoustic device of claim 4 , wherein the channel includes a channel top wall, a channel bottom wall, and a channel side wall, the channel top wall and the channel bottom wall are respectively located at two ends of the channel side wall;

the first hole is disposed on the channel side wall or the channel top wall;

the second hole is disposed on the channel bottom wall; and

the channel bottom wall is configured to press and hold the sound pickup assembly.

6. The acoustic device of claim 5 , wherein the sound pickup assembly comprises a sound pickup element and a protective cover, the protective cover is sleeved on the outer periphery of the sound pickup element, wherein

the protective cover is provided with a groove facing the channel bottom wall;

the sound pickup element is at least partially located in the groove; and

the protective cover abuts and fits with the flange.

7. The acoustic device of claim 5 , wherein a length of the channel in a direction connecting the channel top wall and the channel bottom wall is in a range of 0.45-0.75 mm.

8. The acoustic device of claim 3 , wherein a distance from the first hole to the second hole along the channel is greater than or equal to 4 mm.

9. The acoustic device of claim 3 , wherein the first hole has a same shape as the communication hole.

10. The acoustic device of claim 3 , further comprising a protective component disposed between the at least one of the one or more channel assemblies and the housing to space the communication hole and the first hole apart.

11. The acoustic device of claim 10 , wherein

the protective component includes a first mesh and a second mesh disposed in a stack, the second mesh being closer to the at least one of the one or more channel assemblies than the first mesh.

12. The acoustic device of claim 1 , wherein

the function includes that each control element of the multiple control elements independently controls an audio gain of its corresponding speaker assembly.

13. The acoustic device of claim 12 , wherein

the interactive assembly includes one or more third holes disposed on the housing and buttons disposed in the one or more third holes respectively, and the buttons are configured to trigger the control element to adjust the audio gain of the corresponding speaker assembly.

14. The acoustic device of claim 1 , wherein

the housing includes a first part and a second part, and one end of the first part and one end of the second part are respectively connected to one speaker assembly;

the control circuit assembly includes a main circuit board, the control element is integrated on the main circuit board, and the main circuit board is accommodated in an accommodating space corresponding to an ear-hook housing; and

the control circuit assembly further includes a sub-circuit board, the sub-circuit board is disposed in an accommodating space corresponding to the other ear-hook housing and covers a corresponding volume button hole.

15. The acoustic device of claim 14 , wherein the housing further comprises a third part, the third part is connected between the first part and the second part,

the one or more sound pickup assemblies are respectively disposed in at least two corresponding accommodating spaces of the first part, the second part, and the third part; or

the one or more sound pickup assemblies are disposed in a corresponding accommodating space of the third part at intervals.

16. The acoustic device of claim 15 , wherein the one or more sound pickup assemblies are disposed in the corresponding accommodation space of the third part, one of the one or more sound pickup assemblies is disposed at a middle position of the corresponding accommodating space of the third part, and the remaining sound pickup assemblies are spaced on one side or both sides of the middle position.

17. The acoustic device of claim 16 , wherein the one or more sound pickup assemblies include two sound pickup assemblies and the one or more channel assemblies include two channel assemblies, wherein

the two sound pickup assemblies and the two channel assemblies are respectively disposed in the two ear-hook housings.
