The touch switch 40 is disposed in the base 10 to control the power supply opening and closing of the puller 30. The touch switch 40 is formed with a slot 41 that is embedded with the contact portion 32. When the contact portion 32 and the card slot 41 are embedded with each other At the same time, the touch switch 40 assumes a closed state (OFF); when the contact portion 32 and the card slot 41 are separated from each other, the touch switch 40 assumes an open state (ON). The elastic member 50 is disposed between the seat body 10 and the sliding cylinder 20, and more specifically, the two ends of the elastic member 50 abut against the horn 30 and the seat body 10, respectively. Referring to the third and fourth figures, when the contact portion 32 of the lacing bay 30 and the card slot 41 of the touch switch 40 in the base 10 are mutually fitted, the loudspeaker 1 at this time is in a compression-closed state, sliding. The volume of the resonance chamber S disposed between the cylinder 20 and the base 10 is the smallest, and the total length of the entire loudspeaker 1 is the smallest; in other words, this state can be used as the initial state of the loudspeaker 1 to be installed. On the outer surface of an electronic device (not shown), the loudspeaker 1 does not require a large (i.e., too deep) mounting space, which facilitates miniaturization of the electronic device. Referring to the fifth and sixth figures, when the user applies a force to press the sliding cylinder 2 (or the upper portion thereof), the contact portion 32 of the racquet 30 and the touch switch 40 in the base 10 are pressed. When the card slots 41 are separated from each other, at this time, the elastic member 5 is elongated and its elastic force forces the sliding cylinder 20 to slide upward with respect to the seat body 1 as indicated by the arrow in the fifth figure (that is, the sliding cylinder 20 is away from the seat). The contact portion 32 can be disengaged from the card slot 41 of the touch switch 40, so that the touch switch 4A activates the power supply of the port eight 30. When the sliding cylinder 20 slides upward with respect to the seat 1 直到 until the limit of the seat 1 100 100120484 Form No. A0101 Page 7 / Total 20 pages 1002034643-0 201251474 Flange 11 and ring groove of the inner wall of the sliding cylinder 20 When the two fuses are mutually engaged, the entire loudspeaker 1 is in an extended open state, and the volume of the resonance chamber S' enclosed between the sliding cylinder 20 and the seat body 1 is the largest, and the total length of the entire loudspeaker 丨maximum. [0030] In addition, in order to avoid unnecessary relative rotation between the sliding cylinder 20 and the seat body 1 扭曲, the wire between the horn 3 〇 and the seat body 10 is twisted, such as As shown in the third and fifth figures, a plurality of axial guide grooves 212 may be provided on the inner wall of the sliding cylinder 2〇, and the limiting flange 11 formed on the peripheral wall of the seat body 10 may be guided along the axis guide groove. 212 smoothly slides back and forth in the axial direction of the sliding cylinder 2〇. Referring to the seventh figure, which shows a second example of the present invention, wherein the loudspeaker is provided with a support frame 13 at the bottom of the base 10, the support frame 13 can be opposite to the bottom surface of the base 10. In this way, if the loudspeaker 1 is not installed inside the electronic device, but is electrically connected to the outside of the electronic device, and the orientation of the speaker 23 is not directly facing the user, the user can The cleaver 13 of the 1G wire of the seat body is picked up, so that the entire loudspeaker is erected at an oblique angle, so that the sound emitted by the octagonal 23 can be more accurately sent to the user, and the use is made. Listen to ^ more clearly. In addition, in order to enable the two sound amplifications to be connected in series, a magnet having a magnetic pole not @ (not shown) may be disposed on the bottom surface of the base 10 of each of the loudspeakers 1. In this manner, the user needs to use a pair of expansions. When the sounder is turned on, the bases 1 of the two loudspeakers 1 can be magnetically attracted to each other. If the sound source has been transmitted to the base 10, when the contact portion 喇 100120484 of the case <3 Form No. A0101 Page 8 / Total 20 pages 1002034643-0 201251474 When the card slot 41 of the touch switch 40 is disengaged, the touch switch 40 is activated. It can start the power of the La ° 8 30 and play music directly. [0031] The sliding cylinder 20 occupies most of the outer surface of the entire loudspeaker 1, so that an indicator light, a USB socket or a liquid crystal display screen can be additionally provided on the surface of the sliding base 20, and the indicator light can display the loudspeaker 1 ΟΝ/OFF status' The USB slot can be plugged into the USB connector to obtain other audio signals. The LCD display can display information such as date, time, and stored power. [0033] Compared with the prior art, the present invention has the following effects: [0034] Since the sliding cylinder 2〇 of the present invention can slide down relative to the seat body 1, the horn 30 is mounted on the sliding cylinder The upper opening 21 of the 20, and the elastic member is disposed between the horn 30 and the seat body 1 ,, so when the elastic member 5 〇 is extended, the elastic force of the elastic member 50 pushes the horn 3 〇, so that the taste 八 30 pulls the sliding cylinder The body 20 slides upward with respect to the base 10, and at this time, the contact portion 32 at the bottom end of the slab 30 is disengaged from the slot 41 of the base 10 that touches the switch 40, so that the touch switch turns on the power of the horn 30; therefore, the user only Need to tap the slap 30-down, the racquet 30 and the sliding cylinder 20 will slide up and turn on the power, which is quite convenient to use. On the other hand, when not in use, the user only needs to tap the horn again. The elastic member 50 is compressed until the contact portion 3 2 at the bottom end of the team 3 and the card slot 41 of the touch switch 40 are embedded with each other, and the power of the switch 8 is turned off to turn off the power of the battery 30. In other words, the present invention Reduces volume when not in use, so for installation on an electronic device It is advantageous to limit the internal space to facilitate the miniaturization of the electronic device and the loudspeaker itself.
