Embodiment 1
[0065] Such as figure 1 As shown, this embodiment provides an automatic volume adjustment device, which stores a one-to-one correspondence between air pressure and volume, and also stores a noise threshold, wherein the maximum volume value is ≤85 decibels. The volume automatic adjustment device includes an air sensor 1, a noise collection module 2, a query module 3, a comparison module 4, a drive module 5 and a storage module 6, and the storage module 6 is used to store a corresponding table, the corresponding The table includes this correspondence.
[0066] The air sensor 1 is used to detect the air pressure of the external environment and transmit the air pressure to the inquiry module 3;
[0067] The noise collection module 2 is used to collect noise in the external environment and transmit the noise to the comparison module 4;
[0068] The query module 3 is used to query the volume corresponding to the air pressure as the first volume, and transmit the first volume to th...
Embodiment 2
[0078] This embodiment provides an automatic volume adjustment device, which includes the same components as the volume automatic adjustment device in Embodiment 1, except that the storage module 6 is also used to store another correspondence table, the correspondence The table includes a one-to-one correspondence between noise and volume, and the inquiry module 3 is also used to inquire about the volume corresponding to the noise, and the functions realized by the noise collection module and the comparison module in this embodiment and the noise collection module and the comparison module in Embodiment 1 completely different, specifically:
[0079] The noise collection module 2 is used to collect noise in the external environment and transmit the noise to the inquiry module 3;
[0080] The query module 3 is used to query the volume corresponding to the noise as the second volume, and transmit the second volume to the comparison module 4;
[0081] The comparing module 4 is us...
Embodiment 3
[0089] Such as Figure 4 As shown, this embodiment further includes a first calculation module 7 and a second calculation module 8 on the basis of the automatic volume adjustment device of the second embodiment.
[0090] The first calculation module 7 is used to calculate the average value of the air pressure received in the time period at intervals (such as 10 seconds) after receiving the air pressure transmitted by the air sensor as the first average value, and transmit the first average value to the query module 3, and the query module 3 is used to query the volume corresponding to the first average value;
[0091] The second calculation module 8 is used to calculate the average value of the noise received in the time period as the second average value every time period after receiving the noise transmitted by the noise collection module, and take the second average value The two average values are transmitted to the query module 3, and the query module 3 is used to quer...
