Description

Technical Field

[0001] The utility model relates to the technical field of microphone sound collection, and more specifically to an indication component of a microphone sound collection area. Background Art

[0002] A microphone is a device used to convert sound signals into electrical signals. It is an important component of the audio system and is commonly used in recording, voice communication, music performances, and speeches. The working principle of a microphone is to use sound waves to make the vibrating element generate tiny electrical signals, which are then amplified and processed and finally converted into sounds that can be played by speakers or recording devices. There are many types of microphones, including dynamic microphones, condenser microphones, and semiconductor microphones. They have different characteristics and advantages in different application scenarios. In general, microphones play a vital role in modern society. They provide us with high-quality sound input and are widely used in various fields, including music, entertainment, communication, and recording. In related technologies, the directivity of a microphone is represented by a polar diagram. However, for users who use microphones, polar diagrams are not easy to read, and it is difficult to use polar diagrams to find the best sound receiving area of ​​the microphone. They can only rely on experience to adjust their speaking position relative to the microphone. It is easy for the user's speaking position relative to the microphone to not be in the best sound receiving area.

[0003] In response to the above-mentioned problem that the polar diagram is not easy to read and it is difficult to use the polar diagram to find the best sound receiving area of ​​the microphone, after a lot of searches, the patent number "2202120511174.X" was found, and the name is "A microphone sound receiving area indication component and microphone", which belongs to the field of microphone sound receiving technology. The indication component includes at least one group of light sources and lenses, each light source is arranged inside the shell of the microphone, and each lens is arranged on the shell of the microphone. Each lens is used to change the irradiation direction of the corresponding light source so that the light source indicates the target sound receiving area of ​​the microphone in a sound receiving direction, wherein the target sound receiving area is the sound receiving area where the sound receiving attenuation value of the microphone in the sound receiving direction is less than the preset value, that is, the target sound receiving area can be regarded as the best sound receiving area. In this way, users using the microphone can easily find the best sound receiving area of ​​the microphone in any sound receiving direction with the help of the light source, thereby improving the sound receiving effect.

[0004] However, the technical solution provided by this patent has the following problems:

[0005] (1) The indicator component can only display the reception area, which is relatively fixed and cannot be applied to different usage scenarios;

[0006] (2) The microphone sound receiving area indicator component cannot remind the user of the real-time sound receiving status of the microphone, which may affect the sound receiving effect.

[0007] The utility model can clearly indicate the microphone sound receiving area and the best sound receiving area, and can prompt the user of the real-time sound receiving situation through the indicator light, so that the user can control the volume through the prompt of the indicator light, so that the sound receiving effect is improved.

[0025] The following will be combined with the attached embodiment of the present utility model Figure 1-Figure 3 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0026] See also Figure 1-3In the embodiment of the utility model, a microphone sound receiving area indication component includes: a mounting platform 1, which is mounted inside a microphone housing 14 when in use, a controller 2 is fixedly mounted on the top of the mounting platform 1, and the controller 2 is used to control various electronic components and receive signals from a sound sensor 8, a motor 3 is fixedly arranged above the mounting platform 1, and a rotating platform 4 is fixedly mounted on the output end of the motor 3, and the rotating platform 4 rotates with the rotation of the output end of the motor 3;

[0027] A sound collecting head 5 is fixedly arranged above the rotating platform 4, and the sound collecting head 5 is used to collect sound. A light source 6 is fixedly arranged on the sound collecting head 5, and the light source 6 is synchronously controlled by the microphone switch. When the microphone is used, the light source 6 lights up. A filter 7 is fixedly arranged in front of the light source 6, and the filter 7 is used to disperse the light emitted by the light source 6;

[0028] A plurality of sound sensors 8 are fixedly mounted on the mounting platform 1, and the sound sensors 8 are located around the rotating platform 4. The sound sensors 8 are used to monitor the sound position in real time. When the sound sensor 8 detects the sound, the signal is transmitted to the controller 2. The controller 2 controls the motor 3 to rotate according to the different sound effects received by different sound sensors 8, and turns the sound collecting head 5 to the best sound collecting direction.

[0029] Furthermore, a decibel detector 9 is arranged above the rotating table 4. The decibel detector 9 is used to detect the sound collection situation. The alarm value can be set according to actual needs. An indicator light 10 and a warning light 11 are arranged on the decibel detector 9. The indicator light 10 indicates that the sound detection is normal, and the warning light 11 indicates that the sound detection is abnormal. The indicator light 10 and the warning light 11 have different colors. According to daily living habits, it is recommended that the indicator light 10 is green and the warning light 11 is red; when the sound detected by the decibel detector 9 is within the set normal range value, the indicator light 10 displays normal, and when the sound detected by the decibel detector 9 is lower than the set value, the warning light 11 lights up; during use, when the user's volume is too low, resulting in poor sound collection effect, the warning light 11 lights up. At this time, the user can increase the volume to improve the sound collection effect.

[0030] Furthermore, the filter 7 is a concave lens, and the middle and edge areas thereof are different colors. When the light source 6 passes through the filter, the light is dispersed and refracted, and the light refraction area 13 is located within the sound receiving range of the sound receiving head 5. The middle area of ​​the refraction area 13 is the best sound receiving area 1301, and the edge area is the edge sound receiving area 1302. It is recommended that the middle area of ​​the filter 7 be set to blue light, and according to different sound receiving heads 5, a filter 7 adapted to its best sound receiving range is used, so that the light transmitted through the middle area of ​​the filter 7 is within the sound receiving range 12 of the sound receiving head 5. The edge area of ​​the filter 7 is yellow, and this area belongs to the edge of the sound collecting range 12 of the sound collecting head 5, and its sound collecting effect is slightly poor. When the light source 6 passes through the areas of the filters 7 of different colors, the refracted light is also different. The refraction area 13 of the light source 6 after passing through the filter 7 is the same as the sound collecting range 12 of the sound collecting head 5, and according to the different sound collecting effects, different color areas are displayed after being refracted by filters 7 of different colors within the sound collecting range 12, so that the user can observe the best sound collecting range 12 more intuitively based on vision.

[0031] Furthermore, there are at least three sound sensors 8, preferably twelve sound sensors, and they are evenly distributed around the bottom of the turntable 4 with the rotation axis of the turntable 4 as the center. When in use, the optimal number of sound sensors 8 can be selected according to different usage scenarios and different microphones. When the number of sound sensors 8 is large, the microphone is more sensitive to sound source detection, so that the controller 2 can better control the sound receiving head 5, so that it can be more flexibly rotated to the direction of the sound source, so that the microphone can maintain the best sound receiving effect.

[0032] Furthermore, due to different usage habits of users, the microphone often cannot keep the sound receiving head 5 in the direction of the sound source at all times when in use. The utility model is connected to the controller 2 via the motor 3, and the controller 2 controls the rotation of the motor 3. The sound sensor 8 is connected to the controller 2, which transmits the detected sound signal to the controller 2. After receiving the signal from the sound sensor 8, the controller 2 locates the direction of the best sound source according to the signal from the sound sensor 8, and controls the rotation of the motor 3 so that it drives the rotating table 4 to rotate, so that the sound receiving head 5 can quickly rotate to the direction of the sound source, so that the sound collection effect can be guaranteed.

[0033] Furthermore, the decibel detector 9 is located within the optimal sound receiving range 12 of the sound receiving head 5. Within the optimal sound receiving range 12, the sound receiving effect is the best. The sound effect detected by the decibel detector 9 is closest to the sound receiving effect of the sound receiving head 5, so that the user can more intuitively judge the sound receiving effect through the different colors of the indicator light 10 and the warning light 11 when using it, and then control the sound output volume according to the different indicator lights 10, so as to achieve a better sound receiving effect.

[0034] In order to make the use more convenient, the indicator light 10 and the warning light 11 can be arranged outside the microphone housing, and it is better to set a plurality of them, which are arranged in a ring shape outside the microphone housing, so that the user can observe the sound collection effect more clearly no matter which direction the microphone is in. In order to facilitate identification, the color of the filter 7 is different from the color of the indicator light 10 and the warning light 11;

[0035] Working principle: When in use, the mounting platform 1 is installed inside the microphone housing. When the sound sensor 8 detects the sound, it transmits the signal to the controller 2. The controller 2 locates the sound source through calculation and starts the motor 3 at the same time. The rotation of the motor 3 drives the rotating platform 4 to rotate, thereby driving the sound receiving head 5 to rotate, so that the sound receiving head 5 can quickly rotate to the direction of the sound source; a light source 6 is provided on the sound receiving head 5, and the light source 6 refracts the light through the filter 7, so that the light refraction range overlaps with the sound receiving area, or the light refraction range is within the sound receiving range 12, and the light is refracted and dispersed by the filter 7 to pass through the microphone housing, so that the best sound receiving range 12 of the microphone sound receiving head 5 is more intuitively displayed, so that the user can more intuitively observe the best sound receiving range 12, thereby further improving the sound receiving effect of the microphone.
