The sounding monomer 3 is contained in the receiving space 10.Specifically, the sounding monomer 3 includes being contained in institute
The the second sounding monomer 32 stated the first sounding monomer 31 in the first receiving space 101, be contained in second receiving space 102
And third sounding monomer 33.The frequency of the third sounding monomer 33 is sent out higher than the first sounding monomer 31 and described second
Sound monomer 32.That is, 33 high frequency sounding monomers of the third sounding monomer, the first sounding monomer 31 and second sounding
Monomer 32 is low frequency sounding monomer.
The sounding side of the first sounding monomer 31 is opposite with the upper cover 1 and interval is arranged, the first sounding monomer
31, the operatic tunes 6 before the upper cover 1 and the partition wall 11 surround first jointly.
The sounding side of the second sounding monomer 32 is opposite with the upper cover 1 and interval is arranged, the second sounding monomer
32, the operatic tunes 7 before the upper cover 1 and the partition wall 11 surround second jointly.
The sound channel 4 of leading is formed in the upper cover 1 comprising the first of spaced setting leads sound logical 41 and second and lead
Sound channel 42.
In present embodiment, more preferably, described first, which leads sound channel 41, with described second leads sound channel 42 and is mutually parallel and set
It sets, so that the voice directions of the loudspeaker enclosure 100 are integrally consistent, sounding effect is more preferable.
Described first, which leads sound channel 41, is in communication with the outside the operatic tunes 6 before described first and with surrounding the first ante-chamber 1011 altogether,
It is used to form side vocal structure；First lower cover 21 is arranged with 31 face of the first sounding monomer, first lower cover
21, the upper cover 1, the first sounding monomer 31 and the partition wall 11 surround the first back cavity 1012 jointly, low for improving
Frequency performance.
I.e. first receiving space 101 has been separated into first ante-chamber 1011 and institute by the first sounding monomer 31
State the first back cavity 1012.

Fig. 4 is please referred to, so far, the loudspeaker enclosure 100 passes through the first sounding monomer 31 and the second sounding list
Frequency response performance during body 32 realizes it preferably, while realizing that it is preferably high by the third sounding monomer 33
Frequency frequency response performance finally other than the preferably frequency response performance for showing full frequency band, while having expanded described raise one's voice
The bandwidth of device case 100, the scope of application are wider.
Because the third sounding monomer 33 be set to described in speak channel 5, and the channel 5 of speaking is led positioned at described first
Sound channel 41 and described second lead sound channel 42 between, i.e., the described third sounding monomer 33 is located at the outside for leading sound channel 41
Form exposed structure.
The third sounding monomer 33 being because collision causes its performance bad or even does not work in order to prevent, the utility model
Loudspeaker enclosure 100 is also additionally arranged cushion pad 8, and the cushion pad 8 is annular in shape and is arranged around the mounting hole 51, the cushion pad
8 are connected to the third sounding monomer 33.The cushion pad 8 can be made of flexible or elastic material.
Compared with the relevant technologies, the loudspeaker enclosure of the utility model passes through the first sounding monomer and second sounding
Frequency response performance during monomer is realized, while leading sound channel and described second using described first and leading and formed between sound channel
It speaks channel, and the sounding side for the high frequency sounding list added is made to be connected to the channel of speaking, to realize higher frequency
Response performance realizes Frequency response in ensureing preferably under the premise of not increasing the loudspeaker enclosure volume
Can, the speaker bandwidth for also providing whole higher frequency response performance, and further widening makes its acoustical behavior more
It is excellent.
Above-described is only the embodiment of the utility model, it should be noted here that for the ordinary skill of this field
For personnel, without departing from the concept of the present invention, improvement can also be made, but these belong to this practicality
Novel protection domain.
