Description

1249125 V. INSTRUCTIONS (1) [Technical field to which the invention pertains] The technology, in particular, refers to the [previous technology] speaker for the presentation of sound, playing the role of the full weight = setting, expanding the choice of the machine, less; The weight of = is the original appearance of the music. The team... The second is the design of the speaker. From the material to the structural design, there are heavy factors everywhere, one of the key factors {"sound hole" (or sound ^, out area). The sound produced by the horn unit is released from the sound hole after resonance of the speaker; the size of the output area is directly related to the ^= table. ~ However, the 'female sound phase has completed all the designs at the factory, and does not allow the back-end audio industry or consumers to make adjustments. The single speaker can only be limited to its existing channel design and cannot be changed. . SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is that in the prior art, the speaker cannot provide the feasibility of channel adjustment. In view of the above problems in the prior art, the present invention provides a variable channel sound output device, which mainly comprises a board body and a sound box, wherein the board body has a slot and an adjusting component and the speaker is pivotally connected to the speaker. The sound source of the plate body has a sound source and a sound surface, and the sound source converts the sound signal into sound, and the sound surface is outputted to the sound after the sound phase resonance; wherein the 'speaker is adjusted The component is adjusted and fixed in the rotation angle of the slot,

Page 5 1249125 V. Description of the invention (2) ^ Change the area of the sound surface exposed on the side of the board; pivotally connected to a housing. In addition, the voice of the variable channel provided by the present invention includes the following steps: First, the receiving-audio signal: ^ method, the packet is converted into a sound output; followed by the ~ source sound output Secondly, 'change one of the speakers out. After losing 2 resonance 4, release the sound output to the outside of the speaker. The most effective effect of the invention is to change the volume or to separate the sound output area in order to achieve the effect of the total surface. The θ phase reaches the variable sound. [Embodiment] Referring to Fig. 1, the first preferred embodiment is applied to a table body. The speaker 100, 15'0 is mounted on the board 2G51 of the sound wheel 200, and is connected to the host computer m to provide a f-sound output function for the computer desk; the following is only explained by the speaker 100. 4 210 The speaker 100 is pivotally connected to the slot 2〇1 of the board body 2 05. In other words, the box 100 is rotatably coupled to the board body 250.曰: the box 1 〇〇 main _ body 110, the sound source C inside the box 110 and the sound emitting surface 12 〇; wherein the sound source can convert the sound signal from the computer host 21 〇 other playback devices into Sound output, the actual L f source can be a general Ra A monomer, or a piezoelectric sound component, and the sound surface 1 = 0 is commonly known as the "sound hole", and its wheel area will affect the sound output. After the resonance in the speaker 100, the sound of the sound is released. The housing 110 has shafts m and 112 on both sides thereof, respectively embedded in the slot 2〇1

Page 6 1249125 V. Invention Description (3) The shaft holes 202 and 203 on both sides, so that the entire speaker 1 can be rotated by the two shaft columns 111 and 112 as the shafts in the slot 201 of the plate body 205. The top of the speaker 100 has a dome-shaped grip 140 for the hand-held speaker, and the grip 140 can be received in the U-shaped recess 141 when not in use. As for the positioning of the phase 1 0 0, a plurality of consecutively arranged positioning holes 130 are arranged on the side of the casing 11 , and a slider 20 6 is disposed on the plate 204 to the groove 204 adjacent to the slot 201 . Inside, the pocket 204 has an elastic member 209 for reciprocating linear displacement of the slider 206. The slider 206 is formed into an L-shaped block, and has an embedded portion 208 protruding into the slot 201, and can be embedded in the positioning hole 1130 of the speaker 1 to position it; the slider 2 〇6 has a trigger portion 2 0 7 is exposed on the surface of the table 2 05 for manual operation to release the embedded portion 2 of the slider 2〇6 to the fixed position of the speaker 100. Please refer to the second figure. When you want to use the speaker 1〇〇, pull the slider 206 off the positioning hole 1 3 0, and lift the speaker 1 握 up with the grip 1 4 0 'to let the speaker 100 out The output area of the sound surface 120 is half exposed on the top side of the plate body 2 〇 5, and the portion located on the bottom surface of the plate body 2 〇 5 is about one quarter. In this way, the upper and lower channels are formed by the partition of the plate body 50; and the sounds outputted by the upper and lower channels are slightly different due to the unequal wheel area, and the different sound combinations are reflected by the indoor space. After that, it will produce an unexpected sound effect. As shown in the second figure, the sound output surface 120 is exposed to the output area of about seven-eighths of the top surface of the table body 205, that is, the effect of almost mono only sounds all from the top of the plate body 2 0 5 Side transmission, otherwise, it is completely retracted below the plate body 2 0 5 , the sound is sent by the bottom side of the board 2〇5; the sound effect of the two

And the adjustment of the A; _3C map 'about the structure of the speaker pivoted to the board body telescopic two rods 3 〇〇, ", can also be achieved with a telescopic ejector 300. 3 = Γ and 2 the bottom side of the plate 310 'the other end is pivoted to the speaker = the speaker 320 makes a change in the angle of rotation. In practice, ΞίΓΓΛ pressure ejector 'utilizes the mechanical or electronic control effect of the 2,128 push speaker 3 2 〇 displacement amount, to achieve the sound channel of the change channel 'out t; sound 2 application ι' can also be used The present invention changes to see the mUY// the same mono sound effect change. Wide is to close the channel below. According to this 彳,, -^ I to achieve the sound effect of the early channel changes. It can be used to convert the sound output of the variable channel provided by Ding Mingming. It can also be: 2 to output the sound of the speaker, and become a multi-channel system change. I is also set in the body, the sound system of the mono system is fixed. The adjustment components used in this month are not limited. In addition to the above, the complex: t slider and the combination of the elastic ' or expansion The root of the application of the ejector. Equivalent elements in the technical field are applicable.
