Description

Microphone, its control method and noise reduction method

Technical field

The present invention relates to the technical field of an external device, and more particularly to a microphone, a control method thereof, and a noise reduction method.

Background technique

With the rapid development of science and technology, the camera function of smart phones is becoming more and more powerful, making the phone gradually replace some professional camera equipment, and even if some high-pixel cameras are applied to the phone, it can make the phone comparable to high-end Camera photo and video functions. Therefore, even in some occasions or scenes that require professional camera shooting, such as interviews, shooting, live recording, etc., you can also complete high-quality shooting tasks by operating your mobile phone, especially in the mobile office or self-media increasingly popular situations under.

However, although the mobile phone meets the shooting requirements of professional shooting scenes to a certain extent, for example, by connecting some professional equipment (such as high-definition cameras, etc.) to improve the shooting quality of the mobile phone, it is restricted by the trend of thin and thin mobile phones. External professional equipment cannot be installed directly on a mobile phone. Therefore, a mobile phone case with an external function can conveniently install various external devices on a mobile phone to greatly enhance the corresponding function of the mobile phone, so that the mobile phone can fully meet various professional shooting tasks.

At present, many mobile phone cases with external functions have appeared on the market. Usually, one side of the mobile phone case has a mobile phone adapter for stably adapting to a mobile phone, and the other side of the mobile phone case has an external phone A matching interface is used to correspondingly adapt a specific external device, such as a camera, a flash, and the like. In particular, the mobile phone case also has a grip portion, so that the user can hold the phone case horizontally in the same manner as holding a camera, taking pictures in a relatively easy and convenient manner, thereby greatly improving the user's shooting experience. .

Because in the process of shooting short videos or conducting interview videos, not only need to shoot high-definition video information, but also obtain high-quality audio signals, and the mobile phone generally only has a built-in microphone, and when the mobile phone and a mobile phone case are suitable When assembled together, the receiving hole on the phone will be partially or completely blocked, and clear or high-quality audio signals cannot be recorded. Therefore, a microphone adapter is provided on the mobile phone case, and is adapted to externally connect a microphone, so that in a scene that needs to be received, a higher quality audio signal can be obtained through the microphone.

Microphones on the market can be divided into omnidirectional microphones, unidirectional microphones and bidirectional microphones according to their directivity. Different types of microphones have different performances and are suitable for different occasions. For example, omnidirectional microphones For the sound from different angles, the sensitivity is the same. Although it can record the sound of the entire environment, it is easily susceptible to the noise of the surrounding environment. This makes this type of microphone suitable for use in situations where the sound source is moving; (Such as cardioid or supercardioid) only has the best radio effect for the sound from the front of the microphone, while the sound from other directions will be attenuated, making this type of microphone suitable for personal interviews.

However, in the process of photography and recording, especially during interviews, interviewees and interviewees often have frequent conversations. Therefore, an omnidirectional microphone is usually connected in order to collect the interviewee and interviewee's Voice, but the audio quality recorded by the omnidirectional microphone is not high and contains a lot of environmental noise. If a unidirectional microphone is used, only the voice of one of the interviewee and the interviewee can be recorded, so two unidirectional microphones have to be equipped in order to obtain high-quality audio signals. However, due to the small size of the phone case, it is difficult to install two microphones on the phone case at the same time, so it cannot meet the needs of recording high-quality audio in the front and back directions.

Unless it is explicitly indicated in the disclosure of the present invention that the number of the element is only one, the term "a" cannot be understood as being unique or singular, and the term "a" cannot be understood as a limitation on the number.

With the continuous development of society, the self-media has gradually become a new development trend. In particular, as the audio and video processing functions of smart phones become more and more powerful, special computers are no longer needed to process various images or short videos, and the various needs of self-media can be met by mobile phones alone. However, because smartphones are severely restricted by the trend of thin and light development, the quality and effect of the camera or microphone carried by the smartphone is far below the quality and effect of professional cameras or professional microphones. Therefore, in order to improve the user experience, And to meet the needs of the self-media era, a mobile phone case has appeared on the market, which can not only accommodate and protect the smartphone adaptively, but also adaptably install various external devices in order to provide the smart phone with the phone case. The mobile phone is connected with various professional equipment, such as a professional camera, a professional microphone, etc., so that the smartphone can collect higher-definition video information and clearer audio signals.

At present, the common microphones on the market are unidirectional microphones, that is, the unidirectional microphone has only a single pickup head, so as to pick up external sound through the pickup head, and convert the sound into an audio signal, and then the The audio signal amplification circuit of the microphone amplifies the audio signal collected by the pickup head, and transmits the amplified audio signal to other terminals, such as a smart phone, an audio processing terminal, a sound, etc., for processing by the other terminal Or use the audio signal. It is worth noting that, because the one-way microphone can only clearly pick up the sound located in front of the pickup head of the one-way microphone, but cannot clearly pick up the sound located in other directions, therefore, when using the one-way microphone In order to collect high-definition audio signals, the pickup head of the unidirectional microphone needs to be aligned with the direction of the sound source.

In some application scenarios, such as when accessing work through a smart phone, not only the video information of the interviewee must be collected, but also the conversation process between the visitor and the interviewee must be collected. At this time, if a one-way microphone is externally connected to the smart phone, when the visitor asks a question, the pickup head of the one-way microphone needs to be directed toward the visitor, and when the respondent answers, it is necessary to The orientation of the pickup head of the unidirectional microphone is switched, so that the pickup head of the unidirectional microphone faces the interviewee. However, in order to obtain high-definition audio signals, it is usually necessary to firmly mount the external unidirectional microphone on the mobile phone case of the smart phone to prevent the unidirectional microphone from affecting the collected audio signal due to shaking or offset. Therefore, in actual use, it is difficult to adjust the orientation of the pickup head of the unidirectional microphone, that is, the unidirectional microphone cannot collect the visitor and the interviewed person in a complete or high quality. Dialogue process. In addition, even if the orientation of the unidirectional microphone can be adjusted, adjusting the orientation of the unidirectional microphone so frequently will not only introduce a lot of noise into the collected audio signal due to the vibration of the microphone, but also affect the overall atmosphere of the visit. And rhythm.
