Embodiment Construction

[0018] Through the following examples, combined with the attached Figure 1-3 , the technical solution of the present invention will be further specifically described.

[0019] Dual-magnetic circuit dual-sound film speaker, the dual-magnetic circuit dual-sound film speaker includes PCBA9, outer shell 10 and top cover 1, PCBA9 is set at the inner bottom of the shell 10, the overall structure is in the shape of a boss, and is equipped with an upper bracket Ⅰ801 It is assembled and fixed with the lower bracket Ⅱ802 and the housing 10, and includes two sets of voice coils, two sets of sound membranes, and two sets of magnets; it adopts a dual magnetic circuit and double sound membrane structure design to control the low frequency (sound membrane Ⅱ202) and high frequency (sound Membrane Ⅰ201), when the audio is input, the high and low frequency membranes vibrate at the same time, and the high and low frequencies complement each other, so that the low frequency is thick and the high...

Abstract

The invention relates to the field of loudspeakers and provides a loudspeaker with double magnetic circuits and double voice diaphragms. The loudspeaker with double magnetic circuits and double voicediaphragms comprises a PCBA, an outer shell and a top protective cover; the loudspeaker with double magnetic circuits and double voice diaphragms is wholly like a lug boss and is provided with an upper bracket I and a lower bracket II which are assembled and fixed with a shell; and the loudspeaker with double magnetic circuits and double voice diaphragms comprises two groups of voice coils, two groups of voice diaphragms and two groups of magnet structures. As the structural design with double magnetic circuits and double voice diaphragms is adopted to control a low frequency and a high frequency respectively, the high-voice and low-voice diaphragms vibrate at the same time when an audio is input, and the high frequency and the low frequency complement each other so as to enable the low frequency to be simple and honest and the high frequency to be clear. In addition, as the outer bracket structure is made of plastic, the loudspeaker with double magnetic circuits and double voice diaphragms is low in production cost, simple in technology and high in production efficiency.

Description

technical field [0001] The invention relates to the field of speakers, in particular to a speaker with dual magnetic circuits and dual sound films. Background technique [0002] Our most common powered cone speaker. Electric cone speakers used to be referred to as paper cone speakers. Although paper cones were still the main diaphragm in 2014, many polymer material diaphragms and metal diaphragms appeared at the same time. Cone speakers are called cone speakers. Actually. The cone-shaped paper cone speaker is generally composed of three major components: the magnetic circuit system (permanent magnet, core column, magnetic plate), the vibration system (paper cone, voice coil) and the supporting auxiliary system (centering support, basin frame, edge pad). Partial composition. But it is also in the state of single sound film and single magnetic circuit. [0003] Among the headphone speaker products currently on the market, the speaker products are all in the state of monoph...
