Description

Technical Field

[0001] This utility model relates to the field of desktop telephone technology, specifically to a desktop telephone with stable sound transmission. Background Technology

[0002] A desktop telephone is a traditional communication device that is fixed on a desktop or stand. It connects to the telephone network via a telephone line and is equipped with a separate handset and microphone. Users need to hold the handset close to their ear and the microphone close to their mouth to make a call. The device usually has physical buttons for dialing and function operation. Although it has been gradually replaced by wireless devices, it still retains its value in office and other scenarios due to its stability.

[0003] In existing technology, common tabletop telephones lack sound insulation structures on the outside of the handset. In noisy environments, this may interfere with the sound output from the handset, thus affecting the call. In addition, the grooved structure on the surface of the tabletop telephone supports and positions the handheld handset. When the tabletop telephone is accidentally touched or vibrated, the handheld handset can easily detach from the surface of the tabletop telephone, making it susceptible to impacts. Therefore, a tabletop telephone with stable sound transmission is proposed to solve the above problems. Utility Model Content

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A working desktop telephone with stable sound transmission includes a desktop telephone, wherein a handheld receiver is movably mounted on the top surface of the desktop telephone.

[0006] The handheld receiver includes a handle, with an earpiece module fixedly installed at one end of the bottom surface of the handle, and a microphone module fixedly installed at the end of the bottom surface of the handle away from the microphone module.

[0007] Among them, a number of first anti-slip blocks are fixedly connected to the middle of both sides of the outer wall of the grip, and each of the first anti-slip blocks is arranged at equal intervals along the length direction of the grip. A second anti-slip block is fixedly connected to the side wall of the grip and located on the periphery of the earpiece module. Two second anti-slip blocks are respectively provided on both sides of the earpiece module.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-5As shown, a working desktop telephone with stable sound transmission includes a desktop telephone 1, and a handheld receiver 2 is movably mounted on the top surface of the desktop telephone 1; the handheld receiver 2 includes a handle 201, a handset module 202 is fixedly mounted on one end of the bottom surface of the handle 201, and a microphone module 203 is fixedly mounted on the bottom surface of the handle 201 away from the microphone module 203; wherein, a plurality of first anti-slip blocks 204 are fixedly connected to the middle of both sides of the outer wall of the handle 201, and each first anti-slip block 204 is along the handle 201. The grip 201 and microphone module 202 are equidistantly arranged along their length. A second anti-slip block 205 is fixedly connected to the side wall of the grip 201 and to the periphery of the earpiece module 202. Two second anti-slip blocks 205 are respectively provided on each side of the earpiece module 202. A third anti-slip block 208 is fixedly connected to the side wall of the grip 201 and to the periphery of the microphone module 203. Each third anti-slip block 208 has a limiting groove 209 formed in the center of its surface. The limiting groove 209 extends vertically. Two third anti-slip blocks 208 are respectively provided on each side of the microphone module 203. Figure 1 As shown, each anti-slip block increases the contact area between the handheld microphone 2 and the hand when gripping the handle 201, thus making it less likely for the handheld microphone 2 to slip off.

[0028] A backing plate 210 is fitted onto the outer side of the earpiece module 202. The top surface of the backing plate 210 contacts the handle 201. A soundproof tube 211 is adhered and fixed to the bottom surface of the backing plate 210, and the soundproof tube 211 is entirely fitted onto the outside of the earpiece module 202. The inner diameter of the soundproof tube 211 gradually increases from top to bottom. Figures 1-3 As shown, the soundproof tube 211 is hollow inside, so as not to affect the earpiece module 202 from contacting the hook switch in the earpiece storage slot 102;

[0029] Side plates 212 are fixedly connected to the top surface of the abutment plate 210 and near each corner. Insert blocks 213 are embedded and glued to the center of the front and back of each side plate 212. Figure 4 As shown, the insert 213 is made of rubber;

[0030] Each second anti-slip block 205 has a mounting groove 206 in the middle of its inner wall, and each mounting groove 206 extends vertically. The inner wall of each second anti-slip block 205 has slots 207 on both the front and back of the mounting groove 206. Each mounting groove 206 is inserted into the side plate 212, and each slot 207 abuts against the insert block 213. Figures 3-5 As shown, the insert 213 abuts into the slot 207, thereby supporting the abutment 210 and the sound insulation cylinder 211;

[0031] The tabletop telephone 1 includes a main body 101. A handset storage slot 102 is provided on the upper part of one side of the top surface of the main body 101. A microphone storage slot 103 is provided on the top surface of the main body 101 near the handset storage slot 102. Mounting plates 104 are fixedly connected to both sides of the inner wall of the microphone storage slot 103. Limiting shafts 105 are symmetrically fixedly connected to the top surfaces of the two mounting plates 104. A telephone line 106 is fixedly and electrically connected to the side wall of the main body 101. The other end of the telephone line 106 is fixedly and electrically connected to the handle 201. The interior of the handset storage slot 102 abuts against the bottom surface of the soundproof tube 211, and the interior of the microphone storage slot 103 abuts against the bottom surface of the microphone module 203. Each limiting shaft 105 is inserted into and abuts against the interior of a limiting groove 209. Figure 1 As shown, a hook switch is provided in the earpiece storage slot 102. Its function is to detect whether the earpiece is placed in place and trigger the operation of hanging up or ending the call.

[0032] The working principle of this utility model:

[0033] When the handheld receiver 2 is needed, the operator can grasp the entire handle 201 and then lift it along the length of the limiting shaft 105. The limiting shaft 105 slides along the limiting groove 209 until the limiting shaft 105 is completely disengaged from the limiting groove 209. When the earpiece module 202 is brought close to the ear, the soundproof tube 211 first supports the ear, and the soundproof tube 211 deforms under force and reduces the connection gap with the ear, thereby reducing sound leakage and reducing the transmission of external noise to the ear.

[0034] Secondly, when replacing the soundproofing cylinder 211, pull the soundproofing cylinder 211 or the abutment plate 210 downwards towards the handle 201. The insert 213 is squeezed and deformed in the slot 207, thereby misaligning the insert 213 with the slot 207. The side plate 212 can fall down and separate along the mounting groove 206. When reinstalling the soundproofing cylinder 211, insert the side plate 212 into the mounting groove 206. After the insert 213 is aligned with the slot 207, the surface of the insert 213 is no longer squeezed, thereby restoring the insert 213 and abutting into the slot 207, thus fixing the soundproofing cylinder 211 and the handle 201.

[0035] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
