[0068] As shown in the drawings, Figures 1 to 10 According to an embodiment of the present application, a voice processing device 100 is provided, which comprises a panel 10, a back shell 20, a sound pickup module 30 and a sound insulation assembly, at least two sound holes 11 are formed in the panel 10, the at least two sound holes 11 are arranged in a spaced manner along the propagation direction of the voice instruction, the panel 10 cooperates with the back shell 20 and a mounting space is formed between the panel 10 and the back shell 20, the sound pickup module 30 is arranged in the mounting space, the sound pickup module 30 comprises a main board 31 and a plurality of microphones 32 corresponding to the number of sound holes 11, the microphones 32 are arranged on the main board 31, and the sound pickup ports of the microphones 32 are arranged corresponding to the sound holes 11, the sound insulation assembly is provided with a sound transmission structure, and the sound insulation assembly is arranged at least on the outer side of the sound pickup module 30, and the sound holes 11 are in communication with the sound pickup ports through the sound transmission structure.

[0069] Specifically, when the voice processing device 100 is used in a vehicle 1000 and needs to control the vehicle 1000, the user issues a voice control instruction, and since the at least two sound holes 11 (each sound hole 11 corresponds to one microphone 32) are arranged in a spaced manner along the propagation direction of the voice instruction, the voice instruction is determined by the time difference of capturing the voice instruction by each microphone 32, while rejecting other interference noises, to ensure the accuracy of voice input, thereby ensuring the effectiveness of controlling the vehicle 1000.

[0070] It should be understood that in the present application, the arrangement of the at least two microphones 32 forms an end-fire microphone 32 array, when the front microphone 32 (the first microphone 32 to which the sound propagating on the axis arrives) in the array is added with the inverted and delayed signal from the rear microphone 32, this configuration is called a differential array. This can be used to create cardioid, hypercardioid or supercardioid pickup patterns, in which the sound behind the array is greatly attenuated.

[0071] When the distance and time delay between the microphones 32 are properly selected, the beamformed response for a small frequency of aliasing is a cardioid, or supercardioid pattern. The front of the cardioid pattern has no signal attenuation, and theoretically, at 180° position, the incident sound pressure can be completely ignored. For example, the signal attenuation on both sides of the first-order (two microphones 32) delay and beamformer is 6db.

[0072] In addition, the sound received by different microphones 32 in the end-fire array only differs in arrival time, and the differential array beamformer does not have a flat frequency response, but has a high-pass filter response characteristic up to zero frequency. The response of the first-order beamformer (two microphone elements) increases with increasing frequency, and tends to be flat at the aliasing frequency.

[0073] It should be noted that in the embodiments of the present application, each microphone 32 is arranged along the same line, as shown in Figure 1 , and Figure 1 The P in the middle indicates the propagation direction of the voice command, which can propagate from left to right or from right to left. An installation indication is provided on the voice processing device 100, and the voice processing device 100 is installed according to the pointing direction of the installation indication, so that after the voice processing device 100 is installed, it has single directivity when capturing the voice command, thereby ensuring the accuracy of voice input and the effectiveness of controlling the vehicle 1000.

[0074] In addition, as shown in Figures 2 to 4 , a connecting structure 14 is provided on the panel 10, which is used to install the voice processing device 100 on the preset position of the vehicle 1000. The connecting structure 14 can be a connecting hole structure, and a screw or other component is used to pass through the connecting hole structure to fix the voice processing device 100.

[0075] In addition, as shown in Figure 4 or Figure 6As shown, a receiving groove is formed on the side of the panel 10 facing the rear shell 20. The pickup module 30 is disposed in the receiving groove. The main board 31 is connected and fixed to the panel 10 by a connector 39 (e.g., screws). The rear shell 20 is a plate-shaped piece that cooperates with the panel 10 to close the opening end of the receiving groove. The connection between the rear shell 20 and the panel 10 can be achieved by welding, bonding, snap-fitting, or screw connection. In the example of the present invention, the rear shell 20 is connected to the panel 10 by snap-fitting. That is, the rear shell 20 is provided with a mating structure 21 (e.g., a hook), and the panel 10 is provided with an adapter structure (e.g., a slot). The assembly of the rear shell 20 and the panel 10 is achieved by using the snap-fitting structure 21 and the adapter structure. By setting the connection between the rear shell 20 and the panel 10 to snap-fitting (i.e., detachable connection), it is convenient to separate the rear shell 20 and the panel 10 during maintenance, thereby improving the convenience of maintenance.

[0076] It should be understood that the number of microphones 32 can be two, three, four, etc. In the example shown in the accompanying drawings of this invention, only two microphones 32 are shown. Furthermore, to ensure the consistency of performance of each microphone 32, each microphone 32 must be a product of the same model, specification, and batch, and the same stacking method must be used in the overall structure of the device.

[0077] To understand further, such as Figure 4 and Figure 5 ,or Figure 6 and Figure 7 As shown, the voice processing device 100 also includes a first sound insulation component 33 and a second sound insulation component. The first sound insulation component 33 is disposed between the motherboard 31 and the panel 10. The first sound insulation component 33 is provided with a sound-transmitting structure for connecting the sound hole 11 with the pickup port. The second sound insulation component is disposed between the motherboard 31 and the rear shell 20 and is correspondingly disposed with respect to the microphone 32. Specifically, the pickup module 30 is disposed within the installation space formed by the rear shell 20 and the panel 10. A first sound insulation component 33 is provided on the top of the pickup module 30 (the side facing the panel 10), and a second sound insulation component is provided on the bottom of the pickup module 30 (the side facing the rear shell 20). The sound-transmitting structure on the first sound insulation component 33 connects the sound hole 11 of the panel 10 with the pickup port of the microphone 32 (to ensure that voice commands can be effectively captured by the microphone 32). The second sound insulation component is correspondingly disposed to the microphone 32. By setting the first sound insulation component 33 and the second sound insulation component, the top and bottom of the microphone 32 are effectively sealed to avoid interference noise being captured by the microphone 32 and to prevent the leakage of voice commands. This ensures a single path for the transmission of voice commands, thereby further improving the unidirectionality of the voice processing device 100.

In addition, the main plate 31 is in flexible contact with the rear shell 20 through the first rubber sleeve 34, preventing the deformation of the main plate 31 due to stress.
