Referring to fig. 1 to 13:
in the present invention, an acoustic enclosure 1 is provided, and a power supply (not shown) and a woofer 2 and/or a midrange 3 and/or a tweeter 4 electrically connected to the power supply are provided in an internal cavity of the acoustic enclosure 1.
The sound housing 1 is of a cylindrical shape and comprises a cylindrical body, an upper end cover 101 connected with the top end of the cylindrical body, and a lower bottom cover 102 connected with the bottom end of the cylindrical body; the cylindrical main body comprises at least two arc plates which are sequentially connected along the circumferential direction, and the cross section of each arc plate is C-shaped.
In the structure, when the acoustic shell is processed to form the slender shape, the cylindrical main body of the acoustic shell is modularized into the arc-shaped plate, so that the processing difficulty is low and the processing quality of a product is ensured compared with the processing of forming the slender integral cylinder side wall; especially when other structures of the sound are required to be installed in the sound shell or the internal structure of the sound is required to be maintained, the sound shell can be conveniently opened, and when the sound shell is deformed and damaged, the sound shell can be conveniently replaced; the production difficulty of the sound is reduced, and the maintenance difficulty and the maintenance cost are also reduced.
In the embodiment shown in fig. 1 and 2, the cylindrical body is formed by two arcuate plates, a first arcuate plate 103 and a second arcuate plate 104. When the processing difficulty is reduced to a certain degree, the number of the arc-shaped plates is controlled, so that the splicing operation of the arc-shaped plates can be reduced, and two arc-shaped plates are suitable.
Here, preferably, a hole site capable of installing the key module and/or the interface 5 may be formed on the first arc plate 103, and through the key module, man-machine interaction between the user and the sound equipment may be conveniently achieved, and through the interface 5, signal transmission between the sound equipment and other electronic devices may be achieved. For example, a hole site capable of mounting a functional button such as a switch key, a menu key, or an audio adjustment knob may be reserved on the first arc plate 103, and a hole site capable of mounting a signal transmission interface such as an AUX interface or a USB interface may also be reserved on the first arc plate 103. In addition, a hole site capable of installing a socket can be formed in the first arc plate 103, the sound equipment can be connected with an external power supply through the installed socket, a switch hole site can be formed beside the hole site for installing the socket for improving the safety performance of the socket, and a switch installed at the switch hole site can control whether the socket is electrified or not.
The key module and/or the interface 5 installed on the hole site of the first arc plate 103 needs to be electrically connected with the power supply through a large number of connecting wires, if no reasonable wiring design exists, the circuit structure inside the sound equipment shell 1 is disordered, the safety is poor and the maintenance is not easy, therefore, preferably, the accommodating groove 6 can be formed in the inner side of the first arc plate 103, the connecting wires can be buried in the accommodating groove 6 in the production process of the sound equipment, and the accommodating groove 6 is regular and limited to the connecting wires, so that the circuit structure in the sound equipment is clear and tidy.
Here, there are various forms of the accommodating groove 6, for example, the accommodating groove 6 may be cut out on the back surface of the first arc plate 103, but the first arc plate 103 has a limited thickness and is an arc surface, and the cutting process is not easy, so more preferably, as shown in fig. 3, a plurality of ribs 7 may be provided on the back surface of the first arc plate 103, and the accommodating groove 6 may be formed between adjacent ribs 7. Here, the stop 7 may be integrally formed with the first arcuate plate 103.
The key module mounted on the first arc plate 103, as shown in fig. 4 and 5, includes a key body 8, an elastic arm 9 and a spare screw (the key body 8 includes functional buttons such as the switch key and the menu key); in the present invention, the face of the sound housing 1 that can be directly observed by the user during use is set to be the front face thereof, and the face of the key body 8 that can be directly contacted by the user is set to be the front face thereof, then: the back of button body 8 and elastic arm 9 fixed connection, the back of first arc 103 is provided with the installation position, sets up on the installation position can with reserve screw complex screw hole 10.
When the product leaves the factory, the installation position on the elastic arm 9 and the first arc plate 103 is in a hot-melt connection relationship, a hot-melt connection part is formed between the elastic arm 9 and the first arc plate 103, the product leaves the factory and reaches the hand of a user, the hot-melt connection part can be fatigued and damaged along with the pressing and the use of the key body 8 by the user, at the moment, the user obviously lacks tools and skills for maintaining the hot-melt connection part in a hot-melt mode, therefore, the user can hinge the hot-melt connection part by himself, and a spare screw passes through a through hole 901 formed in the elastic arm 9 to be matched with a threaded hole 10, so that the fixed connection relationship between the elastic arm 9 and the installation position is restored.
The structure makes the product avoid introducing connecting pieces such as screws before leaving the factory, selects a stable and reliable hot-melt connection mode to connect the elastic arm with the installation position of the first arc-shaped plate, and if the hot-melt connection part is fatigued and damaged after leaving the factory, a user can use the standby screws to automatically finish the repair of the key module, so that the key module works normally, and the whole maintenance process is convenient and quick.
In the schematic structural diagrams of the embodiment of the key module shown in fig. 4 and 5, it is preferable that:
the mounting position comprises a mounting column 11, and a threaded hole 10 (in this case, the threaded hole 10 is an internal threaded hole) is formed in the mounting column 11 along the axial direction thereof. In this way, it is avoided that the threaded hole is directly formed in the first arc plate 103, so that the strength of the first arc plate 103 is maintained, and of course, if the thickness of the first arc plate 103 is relatively thin, it is not suitable to directly form the threaded hole in the first arc plate 103, otherwise, the depth of the threaded hole 10 is too small to be connected with a spare screw, and if the axial threaded hole 10 is formed in the mounting post 11, a threaded hole with a relatively large depth can be obtained.
Here, preferably, the mounting post 11 includes an upper mounting portion 110 and a lower mounting portion 111, the upper mounting portion 110 is coaxially connected with the lower mounting portion 111, and the lower mounting portion 111 is closer to the first arc plate 103 than the upper mounting portion 110; the radial dimension of the upper mounting portion 110 is smaller than the radial dimension of the lower mounting portion 111, and a step surface B is formed therebetween; the radial dimension of the through hole 901 formed in the elastic arm 9 is larger than the radial dimension of the upper mounting part 110 and smaller than the radial dimension of the lower mounting part 111, and the elastic arm 9 is sleeved on the upper mounting part 110 through the through hole 901 and is supported by the step surface B.
At this time, the elastic arm 9 is thermally fused to the upper end of the upper mounting portion 110 of the mounting post 11, and when the thermally fused connection portion is damaged, it is subtracted to expose the screw hole 10, and the spare screw passes through the through hole 901 to restore the fixed connection relationship of the elastic arm 9 and the first arc plate 103.
In the embodiment shown in fig. 4 and 5, the back surface of the first arcuate plate 103 is preferably provided with an annular cavity structure 12 capable of accommodating the key body 8, and the annular cavity structure 12 is capable of supporting and protecting the key body 8.
In this embodiment, preferably, one elastic arm 9 can be provided to connect two or more key bodies 8, i.e., a plurality of key bodies 8 share one elastic arm, simplifying the structure. More preferably, when the elastic arms 9 are connected with the two key bodies 8, the two key bodies 8 are symmetrically distributed relative to the elastic arms 9, so that the structural stability is improved.
In the above embodiment, preferably, the first arc plate 103 may be provided as a plastic member, and the second arc plate 104 as a metal member; thus, the processing difficulty of arranging the hole site and/or the accommodating groove 6 on the first arc-shaped plate 101 is smaller; the second arc plate 104 is a metal piece, which can effectively maintain the rigidity of the cylindrical main body of the whole sound housing 1, improve the structural stability, and is also beneficial to heat dissipation of electrical components inside the sound housing 1. (preferably, a fin may also be provided on the outer wall of the first arc plate 101.)
Further, the arc surface area of the second arc plate 104 is set larger than the arc surface area of the first arc plate 103. Because the metal material of the second arc plate 104 is more stable than the plastic material of the first arc plate 103, and the hole site installation key module and/or the interface 5 are not required to be arranged on the first arc plate 103, the maintenance frequency is far lower than that of the first arc plate 103. To reduce maintenance costs, the arc surface area of the second arc plate 104 is set to be larger than the arc surface area of the first arc plate 103.
In the embodiments shown in fig. 1, 6 and 7, a mounting seat (not shown) is provided in the cylindrical body of the sound housing 1, the mounting seat divides the internal cavity of the cylindrical body into an upper cavity and a lower cavity, the upper cavity is provided with a tweeter 4 and/or a midrange 3, the lower cavity is provided with a woofer 2, or the upper cavity is provided with a woofer 2, and the lower cavity is provided with a tweeter 4 and/or a midrange 3.
In the above structure, the midrange loudspeaker 3 and the tweeter 4 share a cavity, and the woofer is located a cavity to alleviate the sound wave vibration of woofer and the sound wave vibration mutual interference that the midrange loudspeaker produced, at this moment, the bass effect of stereo set is better.
In this embodiment, the second arcuate plate 104 includes a first section 104a above the mounting base and a second section 104b below the mounting base; the first arc plate 103 comprises a third section 103a above the mounting base and a fourth section 103b below the mounting base; the second section 104b, the fourth section 103b and the lower bottom cover 102 form the sound cavity of the woofer 2 when the woofer 2 is mounted in the lower chamber, and the first section 104a, the third section 103a and the upper end cover 101 form the sound cavity of the woofer 2 when the woofer 2 is mounted in the upper chamber.
In the prior art, a closed shell with a hollow inside is additionally arranged in an acoustic shell to serve as an acoustic cavity, and then a loudspeaker is arranged in the closed shell, namely, the outside of the loudspeaker firstly wraps the wall of the acoustic cavity and then wraps the acoustic shell. In the above embodiment, a part of the sound housing is directly used as the sound cavity wall, so that the structure is simpler and the materials are saved.
Here, preferably, when the first stage portion 104a, the third stage portion 103a, and the upper end cover 101 form the sound cavity of the woofer 2, a seal ring (not shown in the drawings) is provided between the upper end cover 2 and the cylindrical body, between the mount and the inner wall of the cylindrical body; when the second stage portion 104b, the fourth stage portion 103b and the lower bottom cover 102 form the sound cavity of the woofer 2, sealing rings are provided between the lower bottom cover 102 and the cylindrical body, between the mounting seat and the inner wall of the cylindrical body; therefore, the sealing performance of the sound cavity where the woofer 2 is located is better, and the bass sound effect of the sound is optimized.
In this embodiment, the lower chamber is provided with the woofer 2, and the woofer 2 includes an upper woofer 201 and a lower woofer 202, the upper woofer 201 located inside the lower chamber is provided on the mounting seat at the upper end of the lower chamber, the lower woofer 202 located outside the lower chamber is provided at the lower end of the lower chamber, the upper woofer 201 is the same as the lower woofer 202, and the diaphragm opening of the upper woofer 201 faces upward and toward the outside of the lower chamber, and the diaphragm opening of the lower woofer 202 faces upward and toward the inside of the lower chamber; the upper woofer 201 and the lower woofer 202 are respectively and electrically connected with an audio power amplifier (not shown in the figure), and the electrical positive and negative connection relationship between the upper woofer 201 and the lower woofer 202 and the audio power amplifier is opposite; the power supply is electrically connected with the audio power amplifier.
In the above structure, the upper woofer 201 and the lower woofer 202 are respectively installed at opposite sides of the lower chamber, and are both active speakers, and when electrically connected with the audio power amplifier, the electrical positive and negative connection relationship between the upper woofer 201 and the audio power amplifier is opposite; in this way, the diaphragms of the upper woofer 201 and the lower woofer 202 operate in the reverse state but the phases of the sound waves are the same. The reverse vibration of the vibrating diaphragms of the two woofers is counteracted by the vibration conducted by solid machinery through the mounting surface (the lower chamber wall plate) of the speakers, so that the equidirectional vibration of the lower chamber wall plate is reduced, and the sound and dyeing phenomenon of the lower chamber is also lightened; the air spring between the two woofers acts to reduce harmonic distortion; the sound wave phases of the two woofers are the same, so that the phenomenon that the bass is greatly weakened or even not caused by the reverse phase is avoided. At this time, the air springs in the lower chamber are not disordered and disturbed, the resonance frequency is stable, and harmonic distortion is reduced.
