The mobile phone shell according to claim 1, wherein the mobile phone shell can be integrated in a mobile phone terminal and is adapted to existing mobile phone hardware and systems, and the mobile phone shell can realize real-time dynamic tracking of an ear in a self-use mode, and can adaptively adjust the sound emitting direction of a wave beam to ensure accurate alignment of sound to the ear.
  6. 6. A method for transmitting directional private voice for near-distance ear positioning, characterized in that the mobile phone shell according to any one of claims 1-5 is adopted, comprising the following steps: (1) The mobile phone shell is in communication connection with the mobile phone in a wired or wireless mode, a rear camera of the mobile phone is called in an external mode to obtain the ear position of the target object, and a front camera of the mobile phone is called in a self-use mode to realize real-time tracking of the ear of the user; (2) The mobile phone transmits voice data or system global audio data to a mobile phone shell control module; (3) The control module drives the sounding unit through the beam forming algorithm unit solidified by hardware to form a narrow beam sound field focused on the ear, and close-range directional private voice transmission is completed.

Description

Directional private voice transmission mobile phone shell and method for near-distance ear positioning Technical Field The invention relates to the technical field of mobile communication terminal accessories, in particular to a directional private voice transmission mobile phone shell and a method for near-distance ear positioning. Background The traditional mobile phone loudspeaker adopts an omni-directional sounding design, has the technical defects of easy sound diffusion, poor privacy and easy interference to surrounding personnel in close-range communication or private listening scenes such as public places, meeting rooms, hospitals and the like, and the earphone type audio accessory is required to be worn and used, so that the operation is complicated, the ear discomfort is easy to be caused after the earphone type audio accessory is worn for a long time, and the actual demand of non-wearing close-range point-to-point private voice transmission cannot be met. At present, a directional private voice transmission solution for a mobile communication terminal does not exist, terminal accessory products capable of multiplexing the mobile terminal to realize ear positioning by own hardware and combining a directional sounding technology do not exist in the prior art, no related product design exists, no corresponding technical conception is disclosed, and the problems of 'no wearing, high privacy and accurate directional' voice transmission and listening pain points in a mobile terminal scene can not be solved. Disclosure of Invention 1. Technical problem to be solved The invention aims to solve the following problems in the prior art: (1) The traditional mobile terminal realizes audio output by relying on an omnidirectional sounding loudspeaker or an earphone fitting, has no adaptive light-weight private voice transmission hardware scheme, cannot multiplex the own hardware of the mobile phone to realize accurate positioning, and has high cost and high integration difficulty by additionally adding hardware; (2) In scenes such as public places, meeting rooms, hospitals and the like, the mobile terminal cannot realize point-to-point private voice transmission and listening, privacy is easy to leak when being placed outside in an omni-direction mode, other people are interfered, the earphone is complicated to wear, ear discomfort is easy to be caused when the mobile terminal is used for a long time, and a wearable high-privacy audio transmission mode is lacking; (3) The prior art cannot meet the use requirements of multi-scene audio of a mobile terminal, does not support the mode switching of outward directional transmission and self-private listening, cannot capture and private output global audio such as mobile phone video, music, conversation and the like, and can only adapt to a single application sound source; (4) If the mobile terminal is tried to realize directional sound transmission, the problems that a sound field cannot be dynamically adjusted and the mobile terminal needs to be accurately aligned to an ear to listen to exist, the use posture is limited, the response delay is high, the natural use habit of a daily handheld mobile phone cannot be attached, and the user experience is poor. 2. Technical proposal The invention provides a close-range ear positioning directional private voice transmission mobile phone shell and a method, which realize double-scene accurate positioning by multiplexing front and rear cameras of a mobile phone and drive directional sounding by combining a hardware curing beam forming algorithm, so as to realize close-range and high-privacy voice transmission, and the specific scheme is as follows: 2.1 Mobile phone shell integral structure composition The mobile phone shell only comprises three core components of the mobile phone shell body (100), the control module (200) and the directional sounding unit (300), no extra positioning acquisition hardware is needed, all positioning functions are realized by calling the camera of the mobile phone, the structure is extremely simple and light, and the mobile phone shell is suitable for various mobile phone models. ① The mobile phone shell body (100) adopts a conventional wear-resistant material, compactly distributes the control module (200) and the directional sounding unit (300), ensures the original protection function of the mobile phone shell, and integrates the directional sound transmission core function; ② The control module (200) integrates a main control chip, a communication interface, a hardware curing beam forming algorithm unit (210), and a configurable mode switching unit (220) which is responsible for communication with a mobile phone, camera pickup, sounding unit driving and beam direction regulation; ③ The directional sounding unit (300) is composed of at least one sounding module, is attached to the side edge/top of the mobile phone shell and is fixed in position, and a high-directivity narrow-beam sound field
