[0028] Referring to Figures 1 to 6 The ear cover 100 comprises a shell 10 and a wireless communication module 20. The shell 10 comprises a front cover 11, a rear cover 12 and a sound insulation piece 13. The front cover 11 and the rear cover 12 form a containing cavity 14. The sound insulation piece 13 is arranged in the containing cavity 14 and close to the rear cover 12. The wireless communication module 20 is arranged in the containing cavity 14 and used for information interaction.

[0029] In use, the rear cover 12 of the shell 10 is used to adhere to the user's ear, and the sound insulation piece 13 is used to weaken the sound from the external environment to the human ear to achieve physical noise reduction. By adding the wireless communication module 20, the ear cover 100 can interact with the external environment through the wireless communication module 20, thereby expanding the function of the ear cover 100. For example, the wireless communication module can be configured as a Bluetooth module, and the user can connect with external devices through the Bluetooth module to realize the function of listening to music or making a call. The sound insulation piece 13 can be configured as sound insulation cotton.

[0030] Referring to Figure 6 The ear cover 100 further comprises a listening module 30. The listening module 30 is arranged in the containing cavity 14, and the listening module 30 comprises a digital signal processing unit 33 and a speaker 31 and an audio receiver 32 connected with the digital signal processing unit 33 respectively.

[0031] In the listening module 30, the audio receiver 32 is used to collect the sound in the external environment and convert the sound signal into an electrical signal to the digital signal processing unit 33. After the digital signal processing unit 33 analyzes and processes the digital signal, it is converted into the required sound signal and transmitted to the speaker 31. In this way, the ear cover 100 can process the sound in the external environment before entering the user's ear, that is, the ear cover 100 also has a listening function. Optionally, the audio receiver 32 is configured as a microphone.

[0032] Exemplarily, in an embodiment, the monitoring module 30 can be configured to actively reduce noise. Specifically, the audio receiver 32 collects sound in the external environment and converts the sound signal into an electrical signal and transmits the electrical signal to the digital signal processing unit 33. The digital signal processing unit 33 analyzes and processes the digital signal and causes the speaker 31 to output a sound output opposite to the sound in the external environment, so as to achieve the purpose of actively reducing noise by mutual weakening or canceling.

[0033] In another embodiment, the monitoring module 30 can also be configured to filter sound in the external environment. Specifically, the audio receiver 32 collects sound in the external environment and converts the sound signal into an electrical signal and transmits the electrical signal to the digital signal processing unit 33. The digital signal processing unit 33 analyzes and processes the digital signal and causes the speaker 31 to output only sound waves with a frequency of 1000-2000 Hz. In this way, the earmuff 100 can filter out unwanted noise and retain the sound that is needed. For example, in a construction scene, the earmuff 100 can filter out the sharp metal rubbing sound and retain the human voice, so as to facilitate communication between users and response to the construction site.

[0034] In yet another embodiment, the monitoring module 30 is configured to cause the speaker 31 to output sound with an intensity greater than or less than the intensity of the sound received by the audio receiver 32, and the intensity of the sound output by the speaker 31 is less than or equal to 82 db. That is, the monitoring module 30 can also be configured to weaken or strengthen the sound in the external environment.

[0035] Specifically, the audio receiver 32 collects sound in the external environment and converts the sound signal into an electrical signal and transmits the electrical signal to the digital signal processing unit 33. The digital signal processing unit 33 analyzes and processes the digital signal and causes the speaker 31 to output sound with an intensity less than the intensity of the sound received by the audio receiver 32. In this way, the earmuff 100 can weaken the intensity of the sound in the external environment before transmitting it to the human ear, so as to reduce the damage of the sound to the human eardrum. Preferably, the intensity of the sound output by the speaker 31 is less than or equal to 82 db; or, the audio receiver 32 collects sound in the external environment and converts the sound signal into an electrical signal and transmits the electrical signal to the digital signal processing unit 33. The digital signal processing unit 33 analyzes and processes the digital signal and causes the speaker 31 to output sound with an intensity greater than the intensity of the sound received by the audio receiver 32. In this way, the earmuff 100 can increase the intensity of the sound in the external environment before transmitting it to the human ear, so as to facilitate the user to hear the sound in the external environment clearly.

[0036] Optionally, the wireless communication module 20 is connected to the listening module 30. In this way, the listening module 30 is facilitated to interact with the outside world, for example, an external audio source device can be connected to the listening module 30 through Bluetooth, so that the audio signal of the external audio source device is transmitted to the listening module 30 through Bluetooth, and then transmitted to the ear after being processed by the listening module 30.

[0037] Please refer to Figure 4 and Figure 6 The ear cover 100 further comprises a listening switch 40 and a Bluetooth switch 50, the listening switch 40 is connected to the listening module 30, and the Bluetooth switch 50 is used to turn on or off the Bluetooth. In this way, the Bluetooth and the listening function are independently controlled, and the Bluetooth and the listening function can be used separately. Specifically, when the listening switch 40 is turned on, the user can pair through the Bluetooth, and after the Bluetooth pairing is successful, the Bluetooth enters the use state. At this time, if the listening switch 40 is turned off, the Bluetooth can still continue to work.

[0038] The ear cover 100 further comprises a Bluetooth volume adjustment key 51, which is installed on the surface of the front cover 11 and is used for volume adjustment.

[0039] The listening switch 40 is configured as a scroll wheel 41, which is rotatably connected to the front cover 11, and the listening module 30 is turned on and the volume of the loudspeaker 31 is adjusted by rotating the scroll wheel 41. Specifically, rotating the scroll wheel 41 towards one side to reduce the volume of the loudspeaker 31, and rotating the scroll wheel 41 towards the other side to increase the volume of the loudspeaker 31. Optionally, the listening switch 40 is configured to be turned on at the minimum volume.

[0040] The ear cover 100 further comprises a power module 60, which is installed in the accommodating cavity 14, and the wireless communication module 20 and the listening module 30 are respectively connected to the power module 60.

[0041] Optionally, the power module 60 is configured to include a built-in battery and an external charging port 61.

[0042] The ear cover 100 also has an automatic shutdown function. Specifically, only when the monitoring module 30 is working, if no operation instruction of the user adjustment roller 41 is received within two hours, the ear cover 100 prompts that it is about to shut down. If the user adjusts the roller 41 within 1 minute, the ear cover 100 will not shut down and restart the 2-hour timing; if the user still does not adjust the roller 41 after 1 minute, the ear cover 100 will automatically shut down. When only the Bluetooth is working, if the user does not operate within 5 minutes during the Bluetooth pairing process, the ear cover 100 will automatically shut down. After the Bluetooth pairing is successful, if the user does not use the Bluetooth for information interaction and does not adjust the Bluetooth volume adjustment key 51 and the Bluetooth switch 50, the ear cover 100 prompts that it is about to shut down. If the user presses the Bluetooth volume adjustment key 51 and the Bluetooth switch 50 within 1 minute, the ear cover 100 will not shut down and restart the 2-hour timing; if the user still does not press the Bluetooth volume adjustment key 51 and the Bluetooth switch 50 after 1 minute, the ear cover 100 will automatically shut down. When the Bluetooth and the monitoring module 30 work simultaneously, the user is prompted every two hours, and the prompting method can be to light the indicator light.

[0043] As shown in Figure 3 and Figure 5 The shell 10 also includes an ear pad assembly 15, which is connected to the side of the rear cover 12 away from the front cover 11, and the ear pad assembly 15 includes a filling layer 151 and a soft protective layer 152 wrapped around the outer periphery of the filling layer 151. Optionally, the filling layer 151 is configured as a sponge, and the soft protective layer 152 is configured as a PVC (Polyvinyl chloride) skin.

[0044] As shown in Figures 1 to 3 The ear cover 100 also includes a headband 70 and a connecting bracket 80. The headband 70 extends in a circular arc shape, and the shell 10 and the connecting bracket 80 are respectively configured as two. Each shell 10 is correspondingly connected to one end of the headband 70 through one connecting bracket 80.

[0045] Further, the circular arc-shaped headband 70 forms a receiving space 71, one end of each connecting bracket 80 is hinged to the headband 70, and the other end is hinged to the corresponding shell 10, so that the shell 10 can move relative to the headband 70; the ear cover 100 has a folded state and an unfolded state. When the ear cover 100 is in the folded state, the two shells 10 are respectively accommodated in the receiving space 71; when the ear cover 100 is in the unfolded state, the two shells 10 respectively extend out of the receiving space 71. Specifically, when the ear cover 100 is in the folded state, the two shells 10 are oppositely arranged, and their ear pad assemblies 15 abut against each other. In this way, the structure of the ear cover 100 is more compact, occupies less space, and is thus more convenient for the user to store.

[0046] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.
