[0056] To make the objectives, technical solutions and advantages of the present disclosure clearer, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0057] Figure 1 is a schematic structural diagram of a microphone provided by an embodiment of the present disclosure. As Figure 1 shown, the microphone includes a microphone assembly 10 and a speaker assembly 20.

[0058] Among them, the microphone assembly 10 is located on the top of the speaker assembly 20. As an example, in the embodiment of the present disclosure, the microphone further includes a handle assembly 30. The handle assembly 30 is located at the bottom of the speaker assembly 20 and is connected to the speaker assembly 20. By providing the handle assembly 30, it is convenient for the user to hold the microphone.

[0059] As Figure 1As shown, the speaker assembly 20 includes a housing 21, a passive plate 22, and a plurality of speakers 23. In the embodiments of the present disclosure, taking the speaker assembly 20 including two speakers 23 as an example, in other examples, the speaker assembly 20 may also include only 1 speaker 23, or include 3 or more speakers 23.

[0060] The passive plate 22 is located in the housing 21, dividing the interior of the housing 21 into a first cavity 20a and a second cavity 20b. The first cavity 20a is close to the top of the speaker assembly 20, and the second cavity 20b is close to the bottom of the speaker assembly 20. The side wall of the housing 21 has speaker mounting holes 211, and the speaker mounting holes 211 correspond to the speakers 23 one by one. The speakers 23 are located in the first cavity 20a and in the corresponding speaker mounting holes 211, and the sound-emitting surfaces 231 of the speakers 23 face outside the housing 21.

[0061] In the embodiments of the present disclosure, by providing a passive plate in the housing of the speaker assembly, the passive plate divides the housing into a first cavity and a second cavity. The speaker is located in the first cavity, and the sound-emitting surface of the speaker faces outside the housing. When the speaker emits sound, the sound propagates outside the housing. When the speaker emits sound, it also causes the vibration of the passive plate, and the passive plate strengthens the low-frequency sound, improving the playback effect of the microphone on the low-frequency sound. Moreover, the sound-emitting surface of the speaker and the microphone are located in different orientations, which is beneficial to reducing the crosstalk between the microphone and the speaker. The passive plate is also far from the microphone assembly, thus alleviating the howling problem of the microphone and improving the sound quality and volume of the microphone.

[0062] As an example, in the embodiments of the present disclosure, two opposite side walls of the housing 21 have speaker mounting holes 211, and the two speakers 23 are arranged in opposite directions.

[0063] As Figure 1 shown, the end of the handle assembly 30 is connected to the speaker assembly 20. The microphone assembly 10 is the part for the microphone to pick up sound, the speaker assembly 20 is the part for the microphone to emit sound outward, and the handle assembly 30 is the part for the microphone to be held.

[0064] The speaker assembly 20 of the microphone can be used to play external audio content. For example, an audio signal is input to the speaker assembly 20 of the microphone by other electronic devices and played by the speaker assembly 20. At this time, the microphone can be used as a traditional audio playback device. The speaker assembly 20 of the microphone can also be used to play the sound picked up by the microphone assembly 10. For example, after the microphone picks up the sound, the picked-up sound is converted into an audio signal and output to the speaker assembly 20, and the speaker assembly 20 plays the sound picked up by the microphone assembly 10. By adjusting the volume of the sound played by the speaker assembly 20 so that the volume of the sound played by the speaker assembly 20 is greater than the volume of the sound collected by the microphone assembly 10, the microphone can amplify the sound and is applicable to scenarios such as meetings, amplifying the user's voice to facilitate all participants to clearly hear the user's voice.

[0065] As Figure 1 shown, two speakers 23 are installed in two speaker mounting holes 211 of the housing 21, and the sound emitting surfaces 231 of the two speakers 23 face outside the housing 21, and the sound propagates outward along the sound emitting surfaces 231 of the speakers. The two speakers 23 are arranged back to back, and the sound emitting surfaces 231 face in opposite directions, and the emitted sound propagates outside the housing 21 in two opposite directions. During the process of the speaker 23 emitting sound, the negative-phase sound wave of the speaker 23 propagates in the first cavity 20a. Since the two speakers 23 are symmetrically arranged, the negative-phase sound wave can be better cancelled, reducing the influence on the microphone assembly 10 and avoiding howling. Moreover, the negative-phase sound waves weaken each other in the first cavity 20a, also reducing the cancellation of the positive-phase sound wave emitted by the sound emitting surface 231 of the speaker 23 by the negative-phase sound wave, which is beneficial to improving the volume of the microphone.

[0066] When the speaker 23 emits sound, the negative-phase sound wave in the first cavity 20a causes the vibration of the passive plate 22, making the passive plate 22 vibrate and emit sound. The sound emitted by the passive plate 22 propagates to the second cavity 20b and then outward. The vibration of the passive plate 22 strengthens the low-frequency part of the sound, thereby improving the playback effect of the microphone on low-frequency sounds. Exemplarily, the two speakers 23 are used to emit sounds with frequencies in the range of 150 hz to 20 khz, and the passive plate 22 is used to emit sounds with frequencies of 200 hz and below.

[0067] Figure 2 is a schematic structural diagram of a part of a microphone provided by an embodiment of the present disclosure. As Figure 2As shown in the figure, the housing 21 includes a first housing 24 and a second housing 25. The second housing 25 is connected to the bottom of the first housing 24. The speaker mounting holes 211 are located on the side wall of the first housing 24. The bottom of the first housing 24 has a passive plate mounting hole 241. The passive plate 22 is located in the passive plate mounting hole 241. The first housing 24 and the passive plate 22 enclose the first cavity 20a, and the second housing 25 and the passive plate 22 enclose the second cavity 20b.

[0068] The housing 21 is provided as two parts, namely the first housing 24 and the second housing 25, which facilitates the installation of the speaker 23 and the passive plate 22. When installing the microphone, first install the two speakers 23 into the speaker mounting holes 211 of the housing 21, then install the passive plate 22 in the passive plate mounting hole 241, and then connect the second housing 25 to the first housing 24.

[0069] In the embodiment of the present disclosure, the first housing 24 is generally in the shape of a cuboid. The first housing 24 includes a bottom wall 243, a top wall 244, a first side wall 245, a second side wall 246, a third side wall 247, and a fourth side wall 248. The first side wall 245 is opposite to the second side wall 246, and the third side wall 247 is opposite to the fourth side wall 248. The first side wall 245, the third side wall 247, the second side wall 246, and the fourth side wall 248 are connected in sequence to form a cylinder, and the bottom wall 243 and the top wall 244 are respectively connected to the first side wall 245, the third side wall 247, the second side wall 246, and the fourth side wall 248. The passive plate mounting hole 241 is located at the center of the bottom wall 243. The two speaker mounting holes 211 are respectively located on the first side wall 245 and the second side wall 246.

[0070] In other examples, the first housing 24 can also be a pentagonal prism, a hexagonal prism, etc. One or more side walls of the first housing 24 can be provided with speaker mounting holes 211 to install the corresponding number of speakers 23.

[0071] The passive plate 22 is also called a passive radiator. As an example, in the embodiment of the present disclosure, the passive plate 22 includes a diaphragm and an annular bracket. The annular bracket is installed in the passive plate mounting hole 241 and is connected to the bottom wall 243. The diaphragm is arranged on the annular bracket. When the speaker 23 emits sound, the diaphragm can vibrate under the drive of the air in the first cavity 20a to perform passive sound emission.

[0072] As Figure 2 shown in the figure, the speaker assembly 20 further includes a flexible gasket 28. The flexible gasket 28 is arranged around the speaker mounting hole 211. The flexible gasket 28 is located between the speaker 23 and the housing 21, and the flexible gasket 28 is connected to the speaker 23 and the housing 21.

[0073] When the speaker 23 vibrates during sound production, the vibration of the speaker 23 will cause the vibration of the housing 21. If the vibration of the housing 21 is transmitted to the microphone assembly 10, it may cause the microphone assembly 10 to record background noise. By providing a flexible gasket 28 between the speaker 23 and the housing 21, the vibration of the housing 21 can be weakened, preventing the microphone assembly 10 from being affected by the vibration of the speaker 23 and recording background noise, which is beneficial to improving the sound quality of the microphone.

[0074] Optionally, the outer sidewall of the first housing 24 has a plurality of mounting grooves 2441, and the plurality of mounting grooves 2441 are located at the edge of the sidewall of the first housing 24. The second housing 25 has a plurality of positioning protrusions 253, and the plurality of positioning protrusions 253 are located at the edge of the second housing 25 close to the first housing 24. The mounting grooves 2441 and the positioning protrusions 253 correspond one by one. When connecting the second housing 25 to the bottom of the first housing 24, the positioning protrusions 253 are installed in the mounting grooves 2441, thereby connecting the first housing 24 and the second housing 25.

[0075] In other examples, the positions of the mounting grooves 2441 and the positioning protrusions 253 can also be interchanged, that is, the mounting grooves 2441 are provided on the second housing 25 and the positioning protrusions 253 are provided on the first housing 24.

[0076] As Figure 2 shown, the speaker assembly 20 further includes a plurality of shock pads 29, and the shock pads 29 are located in the mounting grooves 2441 and are sandwiched between the positioning protrusions 253 and the inner wall of the mounting grooves 2441. The shock pads 29 can reduce the vibration of the housing, which is beneficial to eliminating the howling phenomenon of the microphone.

[0077] Figure 3 is a schematic structural diagram of a first housing provided by an embodiment of the present disclosure. As Figure 3 shown, the surface of the bottom wall 243 away from the top wall 244 has a limit rib 2431, and the limit rib 2431 is arranged around the passive plate mounting hole 241. The passive plate 22 is located in the limit rib 2431 and communicates with the first cavity 20a through the passive plate mounting hole 241.

[0078] The second housing 25 gradually transitions to a cylindrical shape from the end close to the first housing 24 to the end away from the first housing 24, which is beneficial to connecting the second housing 25 to the handle assembly 30.

[0079] Figure 4 is a schematic structural diagram of a second housing provided by an embodiment of the present disclosure. As Figure 4As shown, the housing 21 further includes a reflection cone 251. The reflection cone 251 is located in the second cavity 20b, and the reflection cone 251 is located at the bottom of the second housing 25, with the tip of the reflection cone 251 facing the passive plate 22. The side wall of the second housing 25 has a plurality of sound outlet holes 252, and the plurality of sound outlet holes 252 are distributed around the reflection cone 251.

[0080] The tip of the reflection cone 251 is arranged facing the passive plate 22. The low-frequency sound that enters the second cavity 20b through the passive plate 22 can diffuse along the side wall of the reflection cone 251 within a 360° range, and then propagate outward through the plurality of sound outlet holes 252. The plurality of sound outlet holes 252 are circumferentially distributed on the side wall of the second housing 25, enabling the sound to propagate outside the second housing 25 within a 360° range.

[0081] As Figure 4 shown, the side wall of the reflection cone 251 is concave. The low-frequency sound propagates from the passive plate 22 to the second cavity 20b and diffuses around along the side wall of the reflection cone 251. The reflection cone 251 is arranged to be concave, which can reduce the loss during the propagation of the sound along the reflection cone 251, prevent the loss of the sound quality of the low-frequency sound, and further improve the low-frequency effect of the sound emitted by the microphone.

[0082] Figure 5 This is a schematic structural diagram of a first housing provided by an embodiment of the present disclosure. As Figure 5 shown, the first housing 24 has a first mounting groove 242, and the first mounting groove 242 is located on the outer side wall of the first housing 24. The speaker assembly 20 further includes a first circuit board 26, and the first circuit board 26 is located in the first mounting groove 242.

[0083] As Figure 5 shown, the first mounting groove 242 is located on the third side wall 247 of the first housing 24. The third side wall 247 has a wiring hole 2421, and the wiring hole 2421 is located at the bottom of the first mounting groove 242, and the wiring hole 2421 communicates with the first cavity 20a.

[0084] The first circuit board 26 is located in the first mounting groove 242. The speaker 23 is connected to the first circuit board 26 through a wire harness 261, and the wire harness 261 is located in the wire routing hole 2421. The first circuit board 26 is used to control the operation of the speaker 23. Arranging the first circuit board 26 outside the first cavity 20a and providing the wire routing hole 2421 facilitates connecting the wire harness 261 from the first circuit board 26 to the speaker 23. Mounting the first circuit board 26 on the outside of the first housing 24 separates the first circuit board 26 from the speaker 23, and their installations do not affect each other. When the first circuit board 26 needs to be repaired, it is not necessary to disassemble the first housing 24, nor will it affect the speaker 23, thus avoiding affecting the acoustic effect of the speaker assembly 20. In addition, arranging the first circuit board 26 outside the first cavity 20a also facilitates connecting the first circuit board 26 to the microphone assembly 10. For example, the side wall of the first mounting groove 242 close to the microphone assembly 10 has a first wire groove 2422, and the wire harness connecting the microphone assembly 10 to the first circuit board 26 can be arranged in the first wire groove 2422. And it also facilitates connecting the first circuit board 26 to the handle assembly 30. For example, the side wall of the first mounting groove 242 close to the handle assembly 30 has a second wire groove 2423, and the wire harness connecting the handle assembly 30 to the first circuit board 26 can be arranged in the second wire groove 2423. The bottom of the first mounting groove 242 also has a plurality of positioning protrusions 2424, and the first circuit board 26 is mounted in the first mounting groove 242 through the positioning protrusions 2424.

[0085] Figure 6 is a schematic structural diagram of a part of a microphone provided by an embodiment of the present disclosure. As Figure 6 shown, the housing 21 of the speaker assembly 20 further includes at least one baffle 27. At least one baffle 27 is located on the side of the first housing 24, the baffle 27 faces the side wall of the first housing 24 having the first mounting groove 242, and the baffle 27 is connected to the first housing 24 and the second housing 25.

[0086] As Figure 6 shown, the baffle 27 faces the third side wall 247 of the first housing 24, and the first circuit board 26 is located between the baffle 27 and the third side wall 247. The baffle 27 can protect the first circuit board 26 from being damaged.

[0087] As Figure 6 shown, the housing 21 of the speaker assembly 20 has a second mounting groove 212. The second mounting groove 212 is located at the top of the housing 21, and the microphone assembly 10 is located in the second mounting groove 212.

[0088] The housing 21 separates the microphone assembly 10 from the speaker 23, avoiding interference between the speaker 23 and the microphone assembly 10, which is beneficial to preventing the occurrence of howling problems. Moreover, the microphone assembly 10 is arranged in the second mounting groove 212 at the top of the housing 21, which is also convenient for collecting the user's voice.

[0089] Figure 7 It is a schematic structural diagram of a part of a microphone provided by an embodiment of the present disclosure. As Figure 7 shown, the microphone assembly 10 includes a microphone 11 and a shock-absorbing bracket 12. The microphone 11 is connected to the shock-absorbing bracket 12, and the shock-absorbing bracket 12 is connected to the housing 21.

[0090] The microphone 11 is installed at the center of the top wall 244 of the housing 21 through the shock-absorbing bracket 12. The shock-absorbing bracket 12 can effectively reduce vibration, thereby reducing the influence of the vibration of the speaker assembly 20 on the microphone 11, which is beneficial to improving the quality of the sound recorded by the microphone 11.

[0091] As Figure 7 shown, the shock-absorbing bracket 12 includes a mounting base 121 and a plurality of elastic arms 122. Exemplarily, in the embodiment of the present disclosure, the shock-absorbing bracket 12 includes two elastic arms 122, and the two elastic arms 122 are symmetrically arranged about the center of the mounting base 121.

[0092] One end of the elastic arm 122 is connected to the mounting base 121, and the other end of the elastic arm 122 is connected to the housing 21. The microphone 11 is located in the mounting base 121.

[0093] The center of the mounting base 121 has a receiving cavity 12a. The microphone 11 is located in the receiving cavity 12a, and the sound pickup surface of the microphone 11 is on the side of the microphone 11 away from the speaker 23, which is beneficial to picking up the user's voice and reducing the influence of the vibration of the speaker 23 on the microphone 11. The mounting base 121 is connected to the housing 21 through a plurality of elastic arms 122.
