[0007] Preferably, the internal cavities of the upper speaker, the lower speaker, the left speaker and the right speaker are connected.
[0008] Preferably, the internal cavities of the upper speaker, the lower speaker, the left speaker and the right speaker are isolated from each other.
[0009] Preferably, the upper speaker and the lower speaker are tweeters, and the left speaker and the right speaker are woofers.
[0010] Preferably, the upper speaker and the lower speaker are woofers, and the left speaker and the right speaker are tweeters.
[0011] The beneficial effects of the present invention are as follows: the four-speaker speaker structure of the present invention can be arranged with four speakers, and the sound pressure consistency of the four speakers is good, the structure is compact, and space is saved. While ensuring the small size of the speaker, the parts can be reduced, the product cost can be reduced, and the sound quality of the speaker can be guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following briefly introduces the drawings required for describing the embodiments. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work, among which:
[0013] Figure 1 It is a structural schematic diagram of a four-speaker loudspeaker structure of the present invention;
[0014] Figure 2 It is an exploded view of the four-speaker loudspeaker structure of the present invention. DETAILED DESCRIPTION
[0015] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0016] Embodiments of the present invention:
[0017] See also Figure 1 and Figure 2 The four-speaker speaker structure of the present invention includes a centrally arranged U iron 14, wherein the upper and lower sides of the U iron 14 are respectively provided with a first magnet 161, and the left and right sides of the U iron 14 are respectively provided with a second magnet 162, a first washer 151 is provided on the first magnet 161, and a second washer 152 is provided on the second magnet 162, a first voice coil 131 is provided outside the first magnet 161 and the first washer 151, and a second voice coil 132 is provided outside the second magnet 162 and the second washer 152, a first diaphragm 121 is provided at the outer end of the first voice coil 131, and a second diaphragm 122 is provided at the outer end of the second voice coil 132.
[0018] Preferably, a first basin frame 111 is arranged outside the first voice coil 131, and a second basin frame 122 is arranged outside the second voice coil 132. The first basin frame 111 and the second basin frame 122 are fixed together with the U iron 14, and have a supporting and fixing function for the first voice coil 131 and the first diaphragm 121, the second voice coil 132 and the second diaphragm 122.
[0019] Preferably, the first magnet 161, the first washer 151, the first voice coil 131, the first diaphragm 121 and the first basin frame 111 on the upper side of the U iron 14 form an upper speaker, the first magnet 161, the first washer 151, the first voice coil 131, the first diaphragm 121 and the first basin frame 111 on the lower side of the U iron 14 form a lower speaker, the second magnet 162, the second washer 152, the second voice coil 132, the second diaphragm 122 and the second basin frame 122 on the left side of the U iron 14 form a left speaker, and the second magnet 162, the second washer 152, the second voice coil 132, the second diaphragm 122 and the second basin frame 122 on the right side of the U iron 14 form a right speaker. The four speakers, up, down, left and right, are made into one body and share one U iron, which ensures a small size, reduces parts, improves sound quality and reduces costs.
[0020] Preferably, the internal cavities of the upper speaker, lower speaker, left speaker and right speaker are connected, and the four upper, lower, left and right speakers share an inner cavity. As a full-range speaker, the sound can be improved and the sound pressure in these four positions is consistent, which makes up for the disadvantage of the directivity of sound propagation of a single speaker.
[0021] Another speaker layout is that the internal cavities of the upper speaker, the lower speaker, the left speaker, and the right speaker are isolated from each other, the upper speaker and the lower speaker are tweeters, and the left speaker and the right speaker are woofers, or the upper speaker and the lower speaker are woofers, and the left speaker and the right speaker are tweeters. The woofer and the tweeter have independent internal cavities, which can improve the ductility and sound quality of the speaker.
[0022] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
