The invention discloses a sound production device and audio equipment, and the sound production device comprises a magnetic conductive plate, a high pitch unit and a low pitch unit. The high pitch unit is arranged on the magnetic conductive plate, and a sound outlet hole is formed in one side, deviating from the magnetic conductive plate, of the high pitch unit; the bass unit comprises a bass vibrating diaphragm and a bass voice coil for driving the bass vibrating diaphragm to vibrate, the bass vibrating diaphragm is located on one side, deviating from the magnetic conductive plate, of the sound outlet hole, the bass vibrating diaphragm comprises a vibrating part and a folding ring part annularly arranged on the periphery of the vibrating part, the rigidity of the vibrating part is greater than that of the folding ring part, and the rigidity of the folding ring part is greater than that of the vibrating part. The bass diaphragm is provided with a sound outlet hole, the vibration part is provided with an avoiding hole directly facing the sound outlet hole, the aperture of the avoiding hole is larger than or equal to that of the sound outlet hole, a distance exists between the avoiding hole and the sound outlet hole in the vibration direction of the bass diaphragm, and the avoiding hole is provided with a first damping part. The technical scheme of the invention aims to optimize the structure of the bass diaphragm so as to improve the acoustic performance of the sounding device.
Description
technical field [0001] The present invention relates to the technical field of electro-acoustic conversion, in particular to a sound producing device and audio equipment. Background technique [0002] The sound-emitting device is an important acoustic component in audio equipment. It is a transducer device that converts electrical signals into sound signals. Audio equipment includes earphones, stereos, mobile phones or computers. Nowadays, the market is increasingly pursuing full-band sound quality. In order to meet the full-band sound quality, many multi-unit audio devices that combine tweeters and woofers have emerged, that is, a tweeter and a woofer are placed in one audio device. However, in the existing multi-unit audio equipment, the structure of the bass diaphragm is unreasonable, which easily leads to high and low frequency intermodulation distortion, which affects the acoustic performance of the sound-emitting device. SUMMARY OF THE INVENTION [0003] The main pu...
