Description
Technical Field
The utility model relates to an earphone technical field particularly, relates to a panorama sound earphone.
Background
In the field of movies, surround sound music has been developed for 10 years from the academic discussion corpus of music recorders in 2003, and a unified concept of music mixing and surround sound production has been gradually achieved.
Dolby panoramas (Dolby Atmos) is a 3D surround sound technology developed by Dolby laboratories, released in 2012 on 24/4/2012. The sound effect generation device breaks through the concepts of 5.1 sound channels and 7.1 sound channels in the traditional sense, and can combine film contents to present dynamic sound effects; the sound effect from far to near is more truly created; the loudspeaker box is additionally arranged on the ceiling in a matched mode, so that the sound field is surrounded, more sound details are displayed, and the viewing experience of audiences is improved. Dolby panoramas suitable for theaters have a maximum of 64 individual speakers to present content, and up to 128 tracks.
Although dolby panoramas suitable for theaters have a maximum of 64 individual speakers to present content, in practice 7.1.4 channels are used for production in an actual studio, and other tracks are generated based on algorithms. The production of panoramic sound requires at least 12 sound channels of multi-channel sound cards, 12 sound boxes and professional software such as ProTools Ultimate 2021. For civil playing devices, dolby panoramic sound decoding is required to decode HDMI2.0 program source into 12 sound channels, and the 12 sound channels are played through corresponding sound boxes, so that the current panoramic sound music is mainly played by means of a home theater system.
Principle of stereo headphones: stereo headphones are relatively monaural headphones, which cannot be stereo. A stereo headphone, which includes two or more independent sound units, can emit a two-channel stereo sound, unlike a single sound unit of a mono headphone.
The principle of a surround sound enclosure: although we have only two ears, we can sense the spatial position distribution of each sound source by hearing. The time delay difference, the phase difference and the intensity difference are generated by the direct sound of the sound source and the reflected sound of the direct sound in the space where the sound source is located, and the left, right, front and back positions and the upper and lower auditory positions of the sound sources in the space can be accurately calculated through the calculation of the brain of a human body when the direct sound reaches the ears of a human body. Just because the human body has such an auditory judgment processing capability, there is a presence of surround panoramic sound music and sound effects.
Apple iTunes' spatial music is also strictly in accordance with the standard production format of the recording studio when receiving production content, and receives program elements and sound sources that are both surround sound and panoramic sound physical soundtrack concepts as in cinematography. However, the apple headphones, the mobile phones and the iPad are stereo playing systems, and cannot physically play the spatial music received in iTunes, so that at the present stage, the apple headphones, the mobile phones and the iPad can only virtualize an approximate environment of the spatial music based on a software algorithm, rather than truly playing panoramic sound on a real physical sound channel like a home theater. Other earphones with surround sound functions in the market are virtual algorithm earphones, but not true panoramic sound earphones with physical sound tracks, and therefore the music experience of a user is influenced.

The real physical panoramic sound earphone system really and completely accords with the international Dolby panoramic sound making and playing standard.
Description of the invention:
bone conduction is a sound conduction mode, that is, sound is converted into mechanical vibration with different frequencies, and sound waves are transmitted through the skull, the bone labyrinth, the lymph fluid of the inner ear, the spiral organ and the auditory center of a human body.
DAC: digital-to-analog converters, also called D/a converters, DAC for short, are devices that convert digital quantities into analog quantities. The D/a converter is basically composed of 4 parts, namely a weight resistor network, an operational amplifier, a reference power supply, and an analog switch. Analog-to-digital converters, i.e., a/D converters, referred to as ADCs for short, are generally used to convert continuous analog signals into discrete digital signals.
7.1.4: abbreviation for the number of channel placement channels for Dolby panoramas (Dolby Atmos) loudspeakers. 7.1.4 describes the meaning indicated: [7] it represents the number of conventional surround sound speakers (front, center, and surround). The number in the middle of [ 2 ], [ 1] indicates how many powered subwoofers can be connected to the receiver. The last number of [ 2 ], [ 4] represents the number of top or upward-sounding speakers in a Dolby panoramic sound (Dolby Atmos) setting.
The scheme has the following advantages:
1. it is a true sense panoramic sound earphone;
2. compared with a panoramic sound cinema, the panoramic sound cinema has much lower cost for listening to music, as is well known, a good audio-video room environment can meet the acoustic requirements only by accurate acoustic testing and corresponding acoustic decoration, and panoramic sound equipment is also great investment;
3. because the full-view sound earphone is convenient to carry, a user can feel the effect and atmosphere of the immersive space music anytime anywhere;
4. the earphone solves the problem that the interference influences other people when the cinema and the music are played.
In the panoramic field, aiming at the defects of the existing earphones, the panoramic earphone in the true physical sense is to enable more people to conveniently, efficiently and truly feel the panoramic sound effect of the cinema (because the cinema equipment is not available in every person). The technology can achieve the dynamic effect of listening to the sensed space music sound by the existing Dolby panoramic sound theatre through the earphone, and bring sound scenes in virtual reality fields such as VR, AR, yuanuniverse and the like into more immersive experience in the future.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
