[0030] Please refer to the following: Figure 1-4 The present invention proposes an audio playback device, comprising: an earphone unit 20 for playing audio; a headband fastener 10, wherein the earphone unit 20 is detachably disposed on the headband fastener 10 and electrically connected to the headband fastener 10; and a speaker assembly 30, wherein the earphone unit 20 is detachably disposed on the speaker assembly 30 and electrically connected to the speaker assembly 30.

[0031] In this embodiment, there are two earphone units 20, which are used to play left channel audio and right channel audio respectively to achieve a stereo effect. The earphone units 20 are detachably connected to the headband fastener 10. When the earphone units 20 are mounted on the headband fastener 10, the earphone units 20 and the headband fastener 10 are electrically connected to form a headphone. The earphone units 20 can be used as the earpieces of the headphone. After the two earphone units 20 are detached from the headband fastener 10, they can be installed on the speaker assembly 30. The earphone units 20 and the speaker assembly 30 are electrically connected to form a speaker. The earphone units 20 can be used as the speakers of the speaker. It can be understood that after the earphone units 20 are detached from the speaker assembly 30, they can be reinstalled on the headband fastener 10 to form a headphone.

[0032] Therefore, in the technical solution of this embodiment, by detachably mounting the earphone unit 20 onto the headband fastener 10 and electrically connecting it to the headband fastener 10, and simultaneously detachably mounting the earphone unit 20 onto the speaker assembly 30 and electrically connecting it to the speaker assembly 30, the earphone unit 20 is reused as both the earpiece of a headphone and the speaker of a speaker. Users only need to purchase one set of the audio playback device to simultaneously enjoy the near-field acoustic experience of a headphone and the far-field acoustic experience of a speaker, thereby reducing the user's purchase cost.

[0033] Please see Figure 5 Optionally, the headband fastener 10 is provided with a plurality of first electrical contacts (not shown in the figure), and the earphone unit 20 is provided with a plurality of second electrical contacts 21. After the earphone unit 20 is installed on the headband fastener 10, the first electrical contacts and the second electrical contacts 21 make contact and conduction in a one-to-one correspondence.

[0034] In this embodiment, by providing multiple first electrical contacts on the headband fastener 10 and multiple second electrical contacts 21 on the earphone unit 20, after the earphone unit 20 is installed on the headband fastener 10, the first electrical contacts and second electrical contacts 21 make contact and conduction in a one-to-one correspondence, thereby achieving a fixed connection between the earphone unit 20 and the headband fastener 10. Specifically, one of the first electrical contacts and the second electrical contacts 21 can be set as an elastic electrical contact such as a POGO-PIN, and the other can be set as a non-elastic metal contact that contacts the elastic electrical contact. Alternatively, both the first electrical contacts and the second electrical contacts 21 can be set as elastic electrical contacts, or both the first electrical contacts and the second electrical contacts 21 can be set as non-elastic metal contacts. This embodiment is not limited to these limitations.

[0035] Please see Figure 5 Optionally, the first electrical contact includes a first detection electrical contact (not shown), a first positive electrical contact (not shown), and a first negative electrical contact (not shown); the second electrical contact 21 includes a second detection electrical contact 211, a second positive electrical contact 212, and a second negative electrical contact 213; wherein, after the earphone unit 20 is installed on the headband fastener 10, the first detection electrical contact and the second detection electrical contact 211 are in contact and connected, the first positive electrical contact and the second positive electrical contact 212 are in contact and connected, and the first negative electrical contact and the second negative electrical contact 213 are in contact and connected.

[0036] In this embodiment, the connection between the first detection contact and the second detection contact 211 is detected to determine whether the earphone unit 20 is currently connected to the headband fastener 10. When the connection between the first detection contact and the second detection contact 211 is detected, the earphone unit 20 can be controlled to activate the audio playback mode of the headphones. Simultaneously, the first positive contact is connected to the second positive contact 212, and the first negative contact is connected to the second negative contact 213 to transmit the audio signal to be played to the earphone unit 20. In this embodiment, audio playback can only be performed when both earphone units 20 are successfully connected to the headband fastener 10, or audio playback can be performed when only one earphone unit 20 is successfully connected to the headband fastener 10. This embodiment is not limited to this.

[0037] Please see Figure 2 , 5 Optionally, the earphone unit 20 includes: an earphone shell 22, in which a speaker assembly (not shown) and an earphone control chip (not shown) are disposed, the earphone control chip being electrically connected to the speaker assembly and the second electrical contact 21, and the earphone shell 22 also having a jack 23 (see...). Figure 2 The second electrical contact 21 is disposed in the insertion hole 23; the headband fastener 10 is a headband, and the end of the headband is provided with the first electrical contact. After the end of the headband is inserted into the insertion hole 23, the first electrical contact and the second electrical contact 21 make contact and conduction in a one-to-one correspondence.

[0038] In this embodiment, the earphone housing 22 serves as the outer structure of the earphone unit 20. The earphone housing 22 contains a cavity (not shown) for housing the speaker assembly and the earphone control chip. The earphone control chip is electrically connected to the speaker assembly and the second electrical contact 21. The earphone control chip is used to detect whether the first detection electrical contact and the second electrical contact 21 are conductive, thus determining whether the earphone unit 20 is connected to the headband fastener 10. Simultaneously, the earphone control chip is equipped with a power amplifier circuit (not shown). The audio signal output by the earphone control chip is amplified by the power amplifier circuit and then output to the speaker assembly in the earphone unit 20 where the earphone control chip is located for audio playback. Furthermore, the audio signal output by the earphone control chip is amplified by the power amplifier circuit and then transmitted to the other earphone unit 20 through the first positive electrical contact, the first negative electrical contact, and the headband fastener 10 for audio playback, thereby enabling simultaneous audio playback from both earphone units 20 and achieving a stereo effect.

[0039] In this embodiment, by providing a socket 23 on the earphone housing 22 and placing the second electrical contact 21 within the socket 23, the second electrical contact 21 is prevented from being exposed, thus protecting it. Furthermore, the headband fastener 10 is a headband with the first electrical contact at both ends. After the two ends of the headband are respectively inserted into the sockets 23 of the two earphone units 20, the first electrical contact and the second electrical contact 21 in each earphone unit 20 make corresponding contact and conduction, thereby achieving an electrical connection between the earphone unit 20 and the headband. During the insertion of the headband into the sockets 23, the headband can be snapped or threaded onto the earphone housing 22, thereby achieving a stable connection between the headband and the earphone unit 20. It is understood that the headband fastener 10 is not limited to the headband; it can also be an ear hook element (not shown). In this case, the two earphone units 20 can be connected by a wire or wirelessly (such as via Bluetooth).

[0040] Please see Figure 5 Optionally, the earphone housing 22 includes: a side wall 221, on which the jack 23 is formed; a rear shell 222, which together with the side wall 221 forms a sound cavity (not shown), and the speaker assembly is located within the sound cavity.

[0041] In this embodiment, the sidewall 221 can be cylindrical, and the rear shell 222 is fastened to one end of the sidewall 221. The sidewall 221 and the rear shell 222 together form the acoustic cavity, and the headphone control chip and the speaker assembly are located inside the acoustic cavity. Furthermore, the jack 23 is formed on the sidewall 221 without damaging the structure of the rear shell 222, and facilitates the insertion of the headband into the jack 23 for fixed connection with the headphone unit 20. Further, the rear shell 222 has multiple rear cavity through holes 24 (see...). Figure 1 , 2 7) The rear cavity through-hole 24 is used for exhaust to improve the low-frequency performance of the earphone unit 20.

[0042] Please see Figure 3-4 Optionally, the speaker assembly 30 includes: a speaker housing 31, on which an installation opening 32 is provided, and the earphone unit 20 is engaged and fixed within the installation opening 32.

[0043] In this embodiment, by providing a mounting opening 32 on the speaker housing 31 and engaging and fixing the earphone unit 20 within the mounting opening 32, a detachable connection between the earphone unit 20 and the speaker assembly 30 is achieved. It can be understood that the earphone unit 20 can also be threadedly connected to the side wall 221 forming the mounting opening 32. Specifically, since there are two earphone units 20, there are also two mounting openings 32. Each earphone unit 20 is correspondingly positioned within one of the mounting openings 32.

[0044] Please see Figure 4-9 Optionally, the speaker assembly 30 further includes a speaker control chip 33, which is disposed within the speaker housing 31 and has a plurality of third electrical contacts 34. The earphone unit 20 has a plurality of fourth electrical contacts 25, which are located at the end of the earphone unit 20 that extends into the mounting opening 32. After the earphone unit 20 is installed in the mounting opening 32, the third electrical contacts 34 and fourth electrical contacts 25 contact and conduct electricity.

[0045] In this embodiment, by providing multiple third electrical contacts 34 on the speaker control chip 33 and multiple fourth electrical contacts 25 on the earphone unit 20, after the earphone unit 20 is installed on the mounting opening 32, the third electrical contacts 34 and fourth electrical contacts 25 make contact and conduction in a one-to-one correspondence, thereby achieving a fixed connection between the earphone unit 20 and the speaker control chip 33. Specifically, one of the third electrical contacts 34 and the fourth electrical contacts 25 can be set as an elastic electrical contact such as a POGO-PIN, and the other can be set as a non-elastic metal contact that contacts the elastic electrical contact. Alternatively, both the third electrical contacts 34 and the fourth electrical contacts 25 can be set as elastic electrical contacts, or both can be set as non-elastic metal contacts, but this embodiment is not limited to these.

[0046] Please see Figure 4-9 Optionally, the third electrical contact 34 includes a third detection electrical contact 341, a third positive electrical contact 342, and a third negative electrical contact 343; the fourth electrical contact 25 includes a fourth detection electrical contact 251, a fourth positive electrical contact 252, and a fourth negative electrical contact 253; wherein, after the earphone unit 20 is installed on the speaker assembly 30, the third detection electrical contact 341 and the fourth detection electrical contact 251 are in contact and connected, the third positive electrical contact 342 and the fourth positive electrical contact 252 are in contact and connected, and the third negative electrical contact 343 and the fourth negative electrical contact 253 are in contact and connected.

[0047] In this embodiment, the speaker control chip 33 is used to detect whether the third detection contact 341 and the fourth detection contact 251 are connected to determine whether the headphone unit 20 is connected to the speaker control chip 33. At the same time, the speaker control chip 33 is provided with a power amplifier circuit (not shown). The audio signal output by the speaker control chip 33 is amplified by the power amplifier circuit and then output to the two headphone units 20 in two ways, so that the two headphone units 20 can play audio at the same time and achieve a stereo effect.

[0048] Specifically, the speaker control chip 33 detects whether the third detection contact 341 and the fourth detection contact 251 are connected to determine whether the earphone unit 20 is currently connected to the speaker control chip 33. When the connection between the third detection contact 341 and the fourth detection contact 251 is detected, the earphone unit 20 can be controlled to activate the speaker's audio playback mode. Simultaneously, the third positive contact 342 and the fourth positive contact 252 are made connected, and the third negative contact 343 and the fourth negative contact 253 are made connected, and the audio signal to be played is sent to the earphone unit 20. In this embodiment, audio playback can only be performed when both earphone units 20 are successfully connected to the speaker control motherboard, or audio playback can be performed when only one earphone unit 20 is successfully connected to the headband fastener 10. This embodiment is not limited to this.

[0049] Please see Figure 3-8 Optionally, the speaker housing 31 includes: a front housing 311, on which the mounting opening 32 is formed; a rear housing 312, on which the speaker control chip 33 is disposed; and a side housing 313, on which the front housing and the rear housing 312 are respectively connected to the two ends of the side housing 313 to form a sound cavity 314; wherein a passive radiating disk 315 is disposed on the rear housing 312 and / or the side housing 313.

[0050] In this embodiment, the front housing 311, the side housing 313, and the rear housing 312 together form the acoustic cavity 314 of the earphone unit 20. The mounting opening 32 is provided on the front housing 311 for mounting the earphone unit 20. Since the earphone unit 20 is mounted on the front housing 311, the acoustic cavity 314 is actually the rear acoustic cavity 314 of the rear earphone unit 20. Furthermore, by providing a passive radiating disk 315 on the rear housing 312 and / or the side housing 313, the passive radiating disk 315 cooperates with the rear acoustic cavity 314, which can significantly increase the bass effect of the speaker assembly 30.
