Description

Headphones that reproduce the sound field of a music stage

technical field

The utility model relates to an earphone, in particular to an earphone structure for reproducing the sound field of a music stage.

Background technique

There are ear shells on the outside of the ear to collect sound and gather the sound in front of the face, so as to strengthen the front sound and weaken the interference of the back sound, so that the direction, volume and arrival time difference of the sound source in all directions can be clearly distinguished. The brain can distinguish the overall sound field of the sound, and the content of good recorded music also has information such as the specific location and volume of the sound source. This is an extremely important cognitive item for the sound system and ears in music appreciation. When appreciating music sound, it is called sound field stage or music stage (Sound Stage). It is called the sound localization ability of the stereo. The inventor designed a variety of patented audio equipment such as speakers, amplifiers, etc. and compiled: eight key points for judging the sound quality of audio and the sound field performance of various CD recordings (some CD recordings have two-channel surround effects) placed on www. moaudio.com.tw Product Service Q&A FAQ1 and FAQ21 and other data are for music and audio lovers to download and refer to.

Traditional earphones, no matter the earplug type or the earmuff type, their sounding direction is on both sides of the level when facing the face and looking at the two ears, and they sound directly to the ear canal to the inside of the ear. The earphones of this sounding device let the ears It is impossible to distinguish the front and rear sound conditions perpendicular to the face and the sound field of the overall sound. In a natural environment, the ear can distinguish the direction of sound transmission, distance, left and right phase, left and right volume, and sound arrival time difference. Therefore, traditional earphones cannot resemble the sound field and music stage performed by floor-standing speaker boxes. Fig. 1 shows the top view of the existing structure, which is a schematic top view of the existing configuration on the human head 1; wherein the right ear 11 and the left ear 12 of the human head 1 are covered with a right earmuff 21 and a The left earmuff 22, the right earmuff 21 and the left earmuff 22 are connected and fixed with a headband 23, and a speaker unit 24 is respectively installed in the right earmuff 21 and the left earmuff 22 (the horn body can be a traditional speaker unit, Electrostatic speakers, piezoelectric crystals, electromagnetic reed transducers and other sound and power conversion devices), each speaker body monomer 24 is fixed on a speaker baffle 25, and each earmuff 21, 22 is connected with an earmuff inside Cushion 26 makes earmuffs 21, 22 more comfortable when worn and in contact with the skin. Two horn baffles 25 are arranged in parallel with human head ears 11, 12. That is to say, the sounding direction of each horn 24 is determined by the human body The left side or the right side of the human body faces the ears 11, 12 of the human body, so that the ears 11, 12 cannot gather the sound from the front or block the sound from the rear, as a function of distinguishing the front and rear directions of the sound source. This kind of structure propagates sound waves directly, which affects the sound collecting ability of the ear. In order to provide an article that is more in line with actual needs, the inventor has carried out research and development to solve the problems that are easy to occur in the existing use.
