Problems solved by technology
However, due to the small size of the earphone, it is more difficult to assemble the moving coil speaker and the moving iron speaker. Generally, the earphone shell and the moving iron speaker are assembled first, and then the moving coil speaker is put into the earphone shell, but such The assembly method often causes defects in the earphones during the assembly process, and it is also difficult to ensure the stability of the earphones in use, especially the stability of the playback sound quality

The invention discloses a coil and iron integrated sounding unit and an earphone. The coil and iron integrated sound production unit comprises a moving coil loudspeaker. The horn comprises a moving coil horn, a moving iron horn, a sleeve and a horn body, the sleeve is arranged on the moving coil horn in a sleeving mode, a groove sunken inwards is formed in the outer wall of the sleeve, the movingiron horn is arranged in the groove, a sound outlet hole of the moving iron horn is communicated with the horn body, and the moving coil horn is communicated with the horn body through a sound transmission hole of the sleeve. The coil and iron integrated sound production unit is smooth and full in sound production, small in size and convenient to connect with a sound guide tube. The sound made bythe earphone is smooth and plump, and the experience effect is good.
Description
technical field [0001] The invention relates to the field of electro-acoustic technology, in particular to a ring-iron integrated sound unit and an earphone. Background technique [0002] At present, most speakers on the market use a coil to drive the diaphragm to vibrate (commonly known as moving coil), while the other part of the speaker uses an iron plate to drive the diaphragm to produce sound (commonly known as moving iron). The working principle of the moving coil is based on Faraday's law. When the current-carrying conductor passes through the magnetic field, it will receive an electromotive force. Its direction conforms to Fleming's left-hand law. The magnetic flux density is proportional. When the voice coil inputs the audio current of the pointer, the voice coil is subjected to an alternating driving force to generate alternating motion, which drives the diaphragm to vibrate, and repeatedly pushes the air to make sound. The moving iron is also called the precision ...
