Loudspeaker and electronic equipment

Abstract

The embodiment of the invention relates to the field of loudspeaker structures, in particular to a loudspeaker and electronic equipment. The loudspeaker takes a moving coil horn as a first sounding unit, a second sounding unit is arranged in the middle of one side of a magnetic circuit structure of the first sounding unit, and the first sounding unit and the second sounding unit respectively output sounds with different frequencies. The loudspeaker can meet the requirements of high and low pitches at the same time, and the high-frequency extension and low-frequency diving performance is improved. The loudspeaker is small in axial size, and the overall thickness of the loudspeaker is close to the thickness of the single moving coil unit. The second sound production unit and the first sound production unit are coaxially arranged, and the high-pitch vibration sound source surface of the second sound production unit and the low-pitch vibration sound source surface of the first sound production unit are arranged in a coplanar manner, so that the condition of phase difference between sounds of different frequencies can be reduced, and the spatial position feeling of the musical instrument is more accurate. The voice coil and the annular vibrating diaphragm are elastically supported on the basin frame by adopting the elastic suspension, so that the voice coil and the annular vibrating diaphragm can vibrate in a preset range, the condition of swinging polarization is reduced, and the reliability is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of speaker structures, and in particular, to a speaker and an electronic device. Background technique [0002] Sound effects are the basic requirements of speakers (such as headphones and speaker speakers). Users have increasingly higher requirements for sound effects of speakers, requiring speakers with wider high-frequency extension and better low-frequency dive. Traditional speakers use a single speaker unit, which is difficult to meet the optimal design of high and low frequencies at the same time. If there is a bass effect, there will be no high-pitched part, and if there is a high-pitched effect, there will be no bass part, and the output sound quality is poor. Based on this, loudspeaker solutions combining tweeters and woofers have emerged in the industry. figure 1 , figure 2 , image 3 There are three kinds of speakers using a combination of two units. These three kinds of speak...

Problems solved by technology

[0003] The embodiment of the present application provides a speaker and electronic equipment, which solves the problem of sound separation caused by the large axial size of the existing speakers that use a combination of tweeter and woofer, and the phase difference between the tweeter and the woofer when they emit sounds of different frequencies.
