[0059] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0060] Example 1

[0061] refer to Figures 1 to 5 This embodiment provides an earhook bone conduction device, comprising a speaker module 100a and an ear hook 200. The speaker module 100a is mounted on the ear hook 200. A PCB and a battery are also mounted within the ear hook 200, with the battery supplying power to the speaker module 100a via the PCB. The ear hook 200 is also equipped with a control switch and an indicator light, both connected to the PCB.

[0062] When the earhook bone conduction device is worn, the ear hook 200 is attached to the outer periphery of the ear, and the speaker module 10a fits snugly inside the ear. Therefore, the earhook bone conduction device is easy to carry and wear, and is aesthetically pleasing to wear without hindering the wearer's activities.

[0063] The ear hook 200 has an upper and lower end. A hook 210 is located on the upper end, while a microphone is located on the lower end. The microphone receives audio and transmits the audio signal to the speaker module 100a via a PCB, enabling the earhook-style bone conduction device to function as a hearing aid. When worn, the hook 210 engages the ear, resting against the edge of the concha cavity, securing the ear and preventing it from falling off. The speaker module 100a is positioned on the hook 210 and fits snugly within the ear.

[0064] refer to Figure 3 and Figure 4 The speaker module 100a is a first bone conduction speaker, which includes a first magnetic unit 110a, a spring 120a, a first voice coil 130 and a first conductive member 140a. A first magnetic gap 111 is formed in the first magnetic unit 110a. The spring 120a includes an inner ring body 121a and a connecting arm 122a, and the connecting arm 122a is fixedly connected to the inner ring body 121a and extends outward. The inner ring body 121a is suspended on the first magnetic unit 110a, and the connecting arm 122a is fixed to the first magnetic unit 110a through a support member 150. Compared with the spring in the prior art, the spring 120a eliminates the outer ring, has a simpler structure, a smaller size, a larger dynamic range, and a longer stroke during vibration. Since the vibration stroke is related to the low-frequency performance, the longer the vibration stroke, the better the low-frequency performance, so the spring has good bass performance. The first voice coil 130 is disposed on the lower surface of the spring 120a and extends into the first magnetic gap 111. The first conductive member 140a is disposed on the upper surface of the spring 120a. The speaker module 100a with the spring 120a is accordingly small in size, lightweight, and miniaturized, while achieving miniaturization while also improving low-frequency performance. The ear-hook bone conduction device with this first bone conduction speaker is accordingly miniaturized, portable, and comfortable to wear. Furthermore, it can be worn in new ways, such as in confined spaces such as the external auditory canal or auricle.

[0065] refer to Figure 3 The first magnetic unit 110a includes a first U-iron 112 and a first magnet 113. The first U-iron 112 has a U-iron bottom wall 1121, the periphery of which extends upward to form a U-iron side wall 1122. The first U-iron 112 serves as both a magnetic conductor and a housing, further simplifying the structure. The first magnet 113 is a cylindrical magnet, one pole of which is fixed to the middle of the U-iron bottom wall 1121, and the other pole of which is provided with a first washer 1131. The first magnetic gap 111 is an annular gap formed by the side surface of the first magnet 113 and the U-iron side wall 1122.

[0066] refer to Figure 4 The connecting arm 122a includes a connecting portion 1221a and a spiral arm portion 1222a. The connecting portion 1221a is fixedly mounted on the outer periphery of the inner ring body 121a and extends radially outward from the inner ring body 121a. The spiral arm portion 1222a extends circumferentially of the inner ring body 121a, with one end fixedly connected to the end of the connecting portion 1221a.

[0067] refer to Figure 5The support member 150 includes a support ring 151 and three support columns 152. The support ring 151 is provided on the first magnetic unit 110a, and the support columns 152 are fixed to the support ring 151. The end of the connecting arm 122a is provided with a positioning hole 1223, and the support column 152 passes through the positioning hole 1223. The connecting arm 122a is limited and fixed to the support column 152. During installation, the rotating arm portion 1222a fits closely to the support ring 151, providing a good support effect.

[0068] refer to Figure 5 and Figure 6 The support column 152 includes a support column lower portion 1521 and a support column upper portion 1522 disposed on the top surface of the support column lower portion 1521. The support column upper portion 1522 passes through the positioning hole 1223 at the end of the connecting arm 122a. The end of the connecting arm 122a is limited to the top surface of the support column lower portion 1521. The positioning hole 1223 cooperates with the support column upper portion 1522 to perform positioning and fixing functions.

The lower magnet 170a is fixed to the bottom plate 172. The lower coil 180a is disposed around the inner side of the lower magnet 170a. The upper magnet 170b is fixed above the lower magnet 170a. The lower magnet 170a is separated from the upper magnet 170b, forming a second magnetic gap 171 therebetween. The upper and lower magnetic poles of the second magnetic gap 171 are opposite poles. The upper coil 180b is disposed around the inner side of the upper magnet 170b and has a second through hole 181 formed therein. The vibrating plate 190 is suspended in the second magnetic gap 171, with its periphery fixed between the upper magnet 170b and the lower magnet 170a. The centering support 143 is fixed above the upper magnet 170b via the second housing 160b. The second conductive member 140b is movably disposed within the second through hole 181, with its base fixedly connected to the vibrating plate 190 and its top extending through the centering support 143.

Compared to dynamic coil speaker modules, speaker module 100b experiences less signal loss during signal conversion, particularly for high-frequency audio signals, and therefore exhibits superior high-frequency performance. Because conventional dynamic coil bone conduction speakers require a significant amount of space during sound production and involve air in the vibration process, they are unable to effectively control sound leakage. Compared to conventional dynamic coil bone conduction speakers, this second bone conduction speaker is also smaller in size, effectively reducing the area of ​​the in-ear portion and reducing the amount of sound waves radiated into the air, thereby minimizing sound leakage.

[0109] The rest of this embodiment is the same as that of Embodiment 1. The features not explained in this embodiment are all based on the explanations of Embodiment 1 and will not be repeated here.
