Technical field

The invention relates to the technical field of reading technology, and in particular to a spatial audio reading system and method.

Background technique

At present, audio reading in home environments is usually implemented by parents using mobile phones to access the Internet or audio storage terminals such as speakers. Because these audio files are independent of physical books, this "listening" behavior is often " "Accompanying" listening, such as bedtime, wake-ups, and meals, is turned into shallow reading. In most public reading scenarios such as libraries, bookstores, early education institutions, and community bookstores, audio reading is mostly accessed by the PC, and users connect to the PC through listening devices such as headphones to listen. In a few public entertainment places and cultural places such as museums, some voiced content uses the story house approach, that is, in a closed space, a group of audio content is listened to collectively, but the content is often a fixed, single audio content.

The existing digital audio reading of cultural and educational institutions such as existing libraries, bookstores and early education institutions. First, the hardware relies on headphones to meet the requirements of a quiet reading environment. In the digital audio reading scene, headphones are often not accepted by parents.

detailed description

The embodiments of the present invention are described in further detail below with reference to the drawings and embodiments. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

As shown in FIGS. 1 and 2, the spatial audio reading system of this embodiment includes: a polyphonic listening device 3, a recognition device 4, a processor 1, and a database 2. The polyphonic listening device 3 includes: a polyphonic hood 31 and a directional speaker 32. The polyphonic hood 31 is arranged with the openings facing downwards. The directional speaker 32 is set in the polyphonic hood 31 and the playback direction of the directional speaker 32 is also downward. Listening alone, the identification device 4 is used to identify the information of the book, the database 2 stores the audio data corresponding to the book, and the processor 1 is connected to the directional sound 32, the identification device 4 and the database 2, respectively, for identifying the information based on the identification by the identification device 4. The book information retrieves the audio data corresponding to the book from the database 2 and controls the directional speaker 32 for playback.

The identification device 4 may be a two-dimensional code scanner or a two-dimensional code scanning gun, etc. The two-dimensional code scanner is used to scan and identify the two-dimensional code on the book, and the corresponding two-dimensional code is formulated on each book for the needs. At the same time, the audio data corresponding to each book is produced, and one-to-one correspondence with the two-dimensional code information. The identification device 4 may be disposed on a table or a shelf in an audio reading space under the polyphonic hood 31, and may be a fixed type or a handheld type. The recognition device 4 may also adopt other recognition methods besides two-dimensional code recognition, such as barcode recognition or image recognition.

The database 2 may be a cloud database or a network server. The processor 1 is provided with a wireless communication module 7. The processor 1 performs a data exchange connection with the database 2 through a wireless network. The database 2 stores audio and video data corresponding to books, and the related Managers should also update in time to upload and organize the audio and video data corresponding to the new books.

The processor 1 can be a single chip computer, or a computer or ARM.
