In some embodiments of the present application, the structure of the main body module 100 of the recording pen is described.

In consideration of the problem that the existing recording pen has a cuboid structure which is not high in fitting degree with a palm and poor in hand feeling during use, and is easy to damage hands when being held for a long time, the embodiment provides the main body module 100 with the arc structure.

Specifically, the top and bottom of the body module 100 may be provided in an arc-shaped configuration. The front and rear surfaces of the main body module 100 may be configured as a planar structure, so that it is convenient to arrange some common devices, such as physical keys, a touch screen, etc., on the planar structure.

Furthermore, smooth transition connection can be adopted between the planar structures on the front surface and the rear surface and the arc structures on the top and the bottom, so that the arc structures and the planar structures are in smooth transition, and the gripping hand feeling is better due to the integral forming.

In this embodiment, through the arc structural design at top about having adopted recording pen main part module 100, and the planar structure and the arc structure rounding off of two front and back surfaces are connected, and the user holds the portion to be slick and sly arc structure in the use, and is higher with the palm laminating degree, feels better, even hold for a long time and also can not produce the condition of pressing against the hand, therefore it is more convenient to use.

Wherein, the smooth transition connection between the front and back surfaces and the upper and lower top parts can be realized by adopting an arc or other modes. For example, the front surface and the rear surface can be designed to have a flanging structure, the upper top and the lower top are arranged to be arc-shaped structures, and smooth transition connection can be formed through the flanging structure and the arc-shaped structures of the upper top and the lower top.

The main body module 100 may be made of a plastic PC material, a glass ceramic material, or other materials, and for example, the plastic PC material may be injection molded and spray painted, so that the main body module 100 is lighter, thinner, and textured. Because both ends are the arc structure about the main part module, consequently can adopt the integrative technique of moulding plastics of curved surface for main part module 100 back wholeness is higher, and it is better to handle.

Further, as shown in fig. 1:

the microphone set 200 may include a directional microphone 202 and an omnidirectional microphone array 201.

The directional microphone 202 is also called a super directional microphone, and can only pick up sound in a single direction, and the sensitivity to ambient sound in the pick-up direction is higher than that in other directions. The directional microphone 202 may be a condenser microphone, such as a micro-electromechanical microphone, an electret condenser microphone, or the like. The directional microphone 202 can be suitable for directional remote high-fidelity pickup scenes, and the recording tone quality and the recording fidelity of the directional microphone 202 are far higher than those of a silicon microphone. Through adopting different sampling rate different precision to carry out the pickup, can realize remote high-fidelity recording, can restore more real, clear recording scene, when the example adopts the high sampling rate high accuracy pickup collection that is not less than 96KHZ, 24bit, its radio reception distance can reach more than 15 meters.

The directional microphone 202 may be one or more, and fig. 1 illustrates an example of a single directional microphone 202 in this embodiment.

Alternatively, the typical diameter may be up to about 10mm due to the large volume of the directional microphone 202 compared to a silicon microphone. Therefore, the directional microphone 202 can be disposed on the top arc structure of the main body module 100 in this embodiment, and the limited space of the top arc structure is fully utilized.

Further, when the directional microphone 202 is single, it may be disposed at one end or at an intermediate position of the top arc structure, and as shown in fig. 1, the directional microphone 202 may be disposed at the top upper right corner position. Of course, the above merely illustrates one exemplary effect of the placement location, and in addition, the directional microphone 202 may be placed in the top upper left corner or other locations.

Further, as shown in fig. 1, the main body of the directional microphone 202 may be fused into the top arc structure, and a sound receiving hole may be formed in a portion of the top arc structure wrapping the main body of the directional microphone, so as to ensure normal sound receiving of the directional microphone 202.

Optionally, the main body of the directional microphone 202 may be completely integrated into the top arc structure, or may be partially integrated, which may be selected according to design requirements. By fusing the main body of the directional microphone 202 into the top arc structure, that is, by wrapping the main body of the directional microphone 202 with the top arc structure, the directional microphone 202 and the main body are fused into a whole, and the top arc structure can be used as a part of the main body and can also take the protective effect of the directional microphone 202.

The top of the directional microphone 202 may be embedded inside the top arc structure or may protrude from the top arc structure.

In order to ensure that the sound pickup effect of the directional microphone 202 is not affected, sound receiving holes can be formed in the upper surface, the side surface and the front surface and the back surface of the directional microphone 202 according to the embodiment of the application. The sound collecting holes on the upper surface and the front surface and the back surface can be holes made of metal mesh or other materials, and the sound collecting holes on the side surface can also be holes made of metal mesh or other materials.

Further, for the omnidirectional microphone array 201, it may include at least two omnidirectional microphones.

The omnidirectional microphone array 201 is used for 360-degree omnidirectional pickup of a recording scene, and a moving-coil microphone, an aluminum ribbon microphone, a silicon microphone and the like can be adopted. Taking silicon wheat as an example, the consistency is good, the self-adaptive distance can reach 3-5 meters, and the recording requirement of a small scene can be completely met. By adopting the silicon microphone, the characteristics of high sensitivity and consistent phase can be utilized, and the sound source positioning and narrow beam calculation accuracy are facilitated. The sound pickup sampling of more than or equal to 16KHZ/24bit can be adopted in the application, and the output recording data stream is more beneficial to improving the accuracy of voice recognition transcription by combining sound processing modules such as sound source positioning, narrow beam noise reduction, echo cancellation and the like.

Each of the omni-directional microphones of the omni-directional microphone array 201 may be disposed at the front surface of the body module 100. In order to ensure that the omnidirectional microphone array has different pickup effects when receiving sound in an omnidirectional manner, and thus achieve a better effect when performing contrast noise reduction, the omnidirectional microphones in the omnidirectional microphone array 201 may be disposed at upper and lower portions of the vertical central axis of the front surface of the main body module 100. As in fig. 1, an example of two omnidirectional microphones is illustrated. The omnidirectional microphone is arranged on the vertical central axis, so that the omnidirectional pickup is ensured. And the distance is larger through the arrangement of the upper end and the lower end, so that the environmental sounds picked up by the upper omnidirectional microphone and the lower omnidirectional microphone are different, and the noise reduction algorithm is convenient to compare and reduce noise.

Referring to the example of fig. 1, for two omnidirectional microphones, one of the microphones may be disposed on the upper portion of the vertical central axis above the touch screen, and the other microphone may be disposed on the lower portion of the vertical central axis below the navigation direction key. Of course, fig. 1 merely illustrates an alternative arrangement position, and the two omnidirectional microphones may be arranged at other positions on the vertical central axis, and of course, the omnidirectional microphone located at the upper part of the vertical central axis may be arranged at a distance from the top directional microphone in consideration of the inter-device interference problem.

Further, the above layout of the omnidirectional microphone array 201, in cooperation with the directional microphone 202 being disposed at one end of the top arc structure, can ensure that the omnidirectional microphone in the omnidirectional microphone array is spaced from the directional microphone by a sufficient distance, and can reduce device interference between the directional microphone 202 and the omnidirectional microphone array 201.

Of course, for each omnidirectional microphone in the omnidirectional microphone array 201, it may also be disposed at a side of the front surface of the body module 100, such as at the front surface where the omnidirectional microphones are disposed symmetrically with respect to the vertical central axis.

The recording pen comprises a directional microphone 202 and an omnidirectional microphone array 201 through a microphone set 200, so that pickup of the recording pen is composed of the omnidirectional microphone array and the directional microphone and respectively records, pickup data of the omnidirectional microphone array can be processed through echo cancellation, noise reduction and the like, and a recording data stream is obtained and is used for subsequent identification transcription. The pickup data of the directional microphone can be processed by echo cancellation to obtain high-fidelity recording, so that the recording audibility is improved.

The two parts of recording ensure the transcription efficiency and accuracy, ensure the recording audibility of human ears and restore the truest high-fidelity field environment sound.

As shown in fig. 1 and 2, the recording pen of the present application may further include a speaker assembly 500.

The horn assembly 500 may be disposed in the top arc structure, and the sound output effect is ensured based on the airtight sound cavity of the horn assembly 300 formed in the top arc structure.
