Specific implementation mode
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, below in conjunction with the accompanying drawings and have
Body embodiment is described in further detail the utility model.
Referring to Fig. 1, a kind of microphone apparatus is present embodiments provided, including：Sound pick-up 10, for picking up sound；Pickup
Mode control module 20 is switched over for controlling microphone apparatus between nearly record pattern and remote record pattern；Wherein, work as Mike
When wind apparatus is in nearly record pattern, sound pick-up 10 picks up the sound in the first distance range；When microphone apparatus is in remote record mould
When formula, sound pick-up 10 picks up the sound within the scope of second distance；First distance is less than second distance；Shell 1 is installed on shell 1
There are button 30, button 30 to be connect with pickup mode control module 20, is instructed for being sent to pickup mode control module 20, so that
Pickup mode control module 20 is switched over according to instruction, control microphone apparatus between nearly record pattern and remote record pattern.
In the present embodiment, in the same microphone apparatus, existing nearly record pattern, for realizing having for short distance sound
Effect pickup, and have remote record pattern, for realizing effective pickup of remote sound.
Microphone apparatus includes shell 1, and shell 1 is equipped with the button 30 for switch microphone device pattern, in shell 1
Further include sound pick-up 10 and pickup mode control module 20.The operation principle of microphone apparatus is：
User in use, the instruction of pattern, pickup mode control module 20 is closely recorded by 30 input selection of button
The instruction is received, enters nearly record pattern to control microphone apparatus, in nearly record pattern, sound pick-up 10 mainly pick up by pickup distance
Sound in 10 first distance range of sound device, and can ensure that the effect of pickup sound, wherein it is smaller that the first distance, which can be arranged,
Numberical range, to pick up the sound closer apart from sound pick-up 10.Such as user's face close to microphone apparatus singing or closely
When singing, K songs, nearly record pattern can be used.
If user far records the instruction of pattern by 30 input selection of button, pickup mode control module 20 receives the instruction,
Enter remote record pattern to control microphone apparatus, in remote record pattern, sound pick-up 10 is mainly picked up apart from sound pick-up 10 second
Sound in distance range, and can ensure that the effect of pickup sound, wherein it is the number more than the first distance that second distance, which can be arranged,
It is worth range, to pick up the sound apart from sound pick-up 10 farther out.If user is in live streaming, microphone apparatus is mounted on microphone holder
On, apart from user farther out, remote record pattern can be used in microphone apparatus.
As it can be seen that the microphone apparatus in the present embodiment can toggle in nearly record pattern and remote record pattern, when user exists
When needing nearly record in the short time again, and needing remote record, it can be cut implementation pattern directly on the button 30 of a microphone apparatus
It changes, to meet a variety of demands of user.Compared with the prior art, this implementation eliminates user and does not stop to replace the behaviour of microphone apparatus
Make, while eliminating the operations such as series installation, dismounting, tuning.And on this basis, microphone apparatus is closely recording pattern,
Pick up the sound of short distance, it can be ensured that the validity of sound is not in spray wheat, sonic boom, distortion, Pop, rustle etc. no
Good sound quality problem, while the volume of pickup ensures normally, is not in the excessive or too small problem of pickup；Microphone fills
It sets in remote record pattern, picks up remote sound, it can be ensured that the validity of sound, the volume and sound quality of pickup sound are good
It is good, be not in the problem that pickup is small or pickup is suddenly big or suddenly small.
In conclusion above-mentioned same microphone apparatus while ensuring to pick up sound validity, can provide to the user closely
