In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The wireless headset, the wireless headset accessory and the headset system provided by the embodiment of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
The present application provides a wireless headset 10, the appearance of which wireless headset 10 may be exemplified as shown in fig. 1. As shown in fig. 1, at least two metal fitting connection parts are provided on the housing of the wireless headset 10. The two metal mating connection portions are a first mating connection portion 101 and a second mating connection portion 102, respectively. Illustratively, the two metal mating connections may be embodied in the form of gold fingers, and may also be embodied in the form of metal contacts.
In addition, as shown in fig. 2, the wireless headset 10 may be constructed as shown in fig. 2. Specifically, the wireless headset 10 includes a first mating connection portion 101 and a second mating connection portion 102, and further includes a wireless codec module 103, a microprocessor unit 104, a digital signal processing unit 105, a digital-to-analog converter 106, and a first sound emitting unit 107. The output end of the wireless codec module 103 is electrically connected to the first input end of the digital signal processing unit 105. An output terminal of the digital signal processing unit 105 is electrically connected to an input terminal of the digital-to-analog converter 106. A first output end of the digital-to-analog converter 106 is electrically connected to the first mating connection portion 101, and a second output end of the digital-to-analog converter 106 is electrically connected to an input end of the first sound emitting unit 107. The input end of the micro-processing unit 104 is electrically connected to the second mating connection portion 101, and the output end of the micro-processing unit 104 is electrically connected to the second input end of the digital signal processing unit 105.
And the wireless headset is suitable for being in adaptive connection with a headset accessory, in the case of adapting the wireless headset to the headset accessory, the first matching connection part 101 is electrically connected with the fifth matching connection part 203 of the wireless headset accessory 20, the second matching connection part 102 is electrically connected with the sixth matching connection part 204 of the wireless headset accessory 20, and the second sound generating unit in the wireless headset accessory 20 plays the audio file output by the digital-to-analog converter 106.
In this embodiment of the application, the wireless codec module 103 receives a wireless signal transmitted by a wireless signal transmitting device through a wireless transmission protocol, and decodes the wireless signal to obtain a decoded digital audio file. After obtaining the decoded digital audio file, the wireless codec module 103 inputs the decoded digital audio file to the digital signal processing unit 105 through its own output terminal. The wireless signal transmitting device can be a mobile phone, a tablet computer, an MP3, etc.
After receiving the decoded digital audio file sent by the wireless codec module 103, the digital signal processing unit 105 executes an audio processing algorithm on the decoded digital audio file to perform noise reduction, equalization adjustment, and the like on the decoded digital audio file. The digital signal processing unit 105 outputs a digital audio file obtained by executing an audio processing algorithm to the digital-to-analog converter 106 through its own output terminal. Wherein the audio processing algorithm in the digital signal processing unit 105 is set by the micro-processing unit 104.
The digital-to-analog converter 106, upon receiving the processed digital audio file, converts the processed digital audio file into an analog audio file.
In a case where the user places the wireless headset 10 in the wireless headset accessory 20, i.e., the wireless headset is fitted with the wireless headset accessory, the first mating connection 101 in the wireless headset 10 is electrically connected with the fifth mating connection 203 of the wireless headset accessory 20, and the second mating connection 102 is electrically connected with the sixth mating connection 204 of the wireless headset accessory 20. At this time, after determining that the second mating connection portion 102 is electrically connected to the sixth mating connection portion 204 of the wireless headset 20, the microprocessor unit 104 controls the first sound emitting unit 107 to be powered off, that is, controls the first sound emitting unit 107 not to operate. In this way, the path between the digital-to-analog converter 106 and the first sound emitting unit 107 is opened by the power-down of the first sound emitting unit 107.
Meanwhile, since the first mating connection 101 in the wireless headset 10 is electrically connected with the fifth mating connection 203 of the wireless headset accessory 20, and the fifth mating connection 203 of the wireless headset accessory 20 is an input terminal of the second sound emitting unit 201 in the wireless headset accessory 20, a path between the digital-to-analog converter 106 and the second sound emitting unit 201 in the wireless headset accessory 20 is conducted. At this time, the digital-to-analog converter 106 outputs the converted analog audio file to the second sound generating unit 201 of the wireless headset 20 through its own first output terminal, and the analog audio file is played by the second sound generating unit 201 of the wireless headset 20.
The specific process of the micro processing unit 104 controlling the first sound emitting unit 107 to power off may be: the micro-processing unit 104 transmits a notification signal to stop the power supply to the first sound emitting unit 107 to the first power management module 105 of the wireless headset 10. The first power management module 105 stops supplying power to the first sound emitting unit 107 when receiving the notification signal. At this time, the first sound emitting unit 107 is powered down. And the volume of the second sound emitting unit 201 in the wireless headset accessory 20 is larger than the volume of the first sound emitting unit 107 in the wireless headset 10.
Since the volume of the second sound emitting unit 201 in the wireless headset accessory 20 is larger than the volume of the first sound emitting unit 107 in the wireless headset 10, the volume of the voice coil, the diaphragm, the equalizer, and the like in the second sound emitting unit 201 is also larger than the corresponding components in the wireless headset 10. In this way, when the second sound generating unit 201 outputs the analog audio file output by the digital-to-analog converter 106, the frequency response and loudness of the analog audio file can reach ideal values, and the sensitivity of the analog audio file can be improved.
Correspondingly, in case the user does not place the wireless headset 10 in the wireless headset accessory 20, i.e. the wireless headset is not fitted to the wireless headset accessory, the first mating connection 101 in the wireless headset 10 is not electrically connected to the fifth mating connection 203 of the wireless headset accessory 20, and the second mating connection 102 is not electrically connected to the sixth mating connection 204 of the wireless headset accessory 20. At this time, the path between the digital-to-analog converter 106 and the second sound emitting unit 201 of the wireless headset accessory 20 is disconnected. Meanwhile, the micro-processing unit 104 does not perform any processing, i.e., the first sound emitting unit 107 is continuously powered on. Based on this, the path between the digital-to-analog converter 106 and the first sound emitting unit 107 is turned on. The first sound emitting unit 107 plays the analog audio file output from the digital-to-analog converter 106. In this way, proper operation of the wireless headset 10 is ensured.
In an embodiment of the present application, a wireless headset includes: the wireless earphone comprises a wireless coding and decoding module, a micro-processing unit, a digital signal processing unit, a digital-to-analog converter, a first sound-emitting unit, a first matching connecting part and a second matching connecting part, wherein the first matching connecting part and the second matching connecting part are arranged on a wireless earphone shell; the output end of the wireless coding and decoding module is electrically connected with the first input end of the digital signal processing unit; the output end of the digital signal processing unit is electrically connected with the input end of the digital-to-analog converter; the first output end of the digital-to-analog converter is electrically connected with the first matching connecting part, and the second output end of the digital-to-analog converter is electrically connected with the input end of the first sound-emitting unit; the input end of the micro-processing unit is electrically connected with the second matching connecting part, and the output end of the micro-processing unit is electrically connected with the second input end of the digital signal processing unit; the wireless earphone is suitable for being connected with the wireless earphone accessory in an adaptive mode, under the condition that the wireless earphone is matched with the wireless earphone accessory, the first matching connecting portion is electrically connected with the fifth matching connecting portion of the wireless earphone accessory, the second matching connecting portion is electrically connected with the sixth matching connecting portion of the wireless earphone accessory, and the second sound production unit in the earphone accessory plays audio files output by the digital-to-analog converter. In this way, since the volume of the second sound generating unit in the wireless headset accessory is larger than that of the first sound generating unit in the wireless headset, the volumes of the voice coil, the diaphragm, the equalizer and the like in the second sound generating unit are also larger than corresponding components in the wireless headset. Therefore, when the second sounding unit outputs the analog audio file output by the digital-to-analog converter, the frequency response and loudness of the analog audio file can reach ideal values and the like, and meanwhile, the sensitivity of the analog audio file can be improved, so that good hearing can be output to a user.
On the basis of any of the above embodiments, in the case that the wireless headset is not adapted to the wireless headset accessory, the first mating connection part 101 is not electrically connected to the fifth mating connection part 203 of the wireless headset accessory 20, and the second mating connection part 102 is not electrically connected to the sixth mating connection part 204 of the wireless headset accessory 20, and the digital signal processing unit 105 uses the first audio processing algorithm matched to the first sound emitting unit 107.
In case the wireless headset is adapted to the headset accessory, the first mating connection 101 is electrically connected to the fifth mating connection 203 of the wireless headset accessory 20, and the second mating connection 102 is electrically connected to the sixth mating connection 204 of the wireless headset accessory 20, the digital signal processing unit 105 uses a second audio processing algorithm matched to the second sound generating unit.
In this embodiment, when the wireless headset is not adapted to the wireless headset accessory, the first mating connection portion is not electrically connected to the fifth mating connection portion of the wireless headset accessory, and the second mating connection portion is not electrically connected to the sixth mating connection portion of the wireless headset accessory, the path between the digital-to-analog converter and the second sound generating unit is disconnected, and the path between the digital-to-analog converter and the first sound generating unit is connected. At this time, the micro-processing unit controls the digital signal processing unit to use the first audio processing algorithm matched by the first sound emitting unit. In this way, the digital audio file processed by the digital signal processing unit will be more suitable for the first sound emitting unit. Furthermore, when the first sound-emitting unit outputs an analog audio file to the digital-to-analog converter, the best hearing feeling can be achieved within the self-capability range value.
Correspondingly, in the embodiment of the present application, when the wireless headset is adapted to the wireless headset accessory, the first mating connection portion is electrically connected to the fifth mating connection portion of the wireless headset accessory, the second mating connection portion is electrically connected to the sixth mating connection portion of the wireless headset accessory, the path between the digital-to-analog converter and the second sound generating unit is on, and the path between the digital-to-analog converter and the first sound generating unit is off. At this time, the micro-processing unit controls the digital signal processing unit to use a second audio processing algorithm matched with the second sound generating unit. In this way, the digital audio file processed by the digital signal processing unit is more suitable for the second sound generating unit. Furthermore, when the second sound production unit outputs the analog audio file to the digital-to-analog converter, the best hearing feeling can be achieved within the self-capability range value.
In one example, as shown by a solid line in fig. 3, in the case where an analog audio file output by the digital-to-analog converter 106 is played by the first sound emitting unit 107, the bass effect of the first sound emitting unit 107 is poor. And, as shown by the dotted line in fig. 3, since the second sound emission unit 201 is large in volume, it is possible to increase a low frequency at an EQ (equalizer) portion. Therefore, in the case where the analog audio file output from the digital-to-analog converter 106 is played by the second sound emission unit 201, the bass effect of the second sound emission unit 201 is good.
In fig. 3, the abscissa represents frequency, and the ordinate represents gain.
On the basis of any of the above embodiments, as shown in fig. 4, the wireless headset 10 further includes a first power management module 108 and a first power supply 109, and as shown in fig. 4 and 5, the wireless headset 10 further includes two other metal mating connection portions, specifically, a third mating connection portion 110 and a fourth mating connection portion 111 disposed on the housing of the wireless headset 10. Illustratively, the two other metal mating connection portions may be embodied in the form of gold fingers, and may also be embodied in the form of metal contacts.
The third mating connection portion 110 is electrically connected to an input terminal of the first power management module 108 of the wireless headset 10. The fourth mating connection portion 111 is electrically connected to the ground terminal of the first power management module 108. The output of the first power management module 108 is electrically connected to the input of the first power supply 109.
When the wireless headset is adapted to the headset accessory, the third mating connection portion 110 is electrically connected to the seventh mating connection portion 206 of the wireless headset accessory 20, the fourth mating connection portion 111 is electrically connected to the eighth mating connection portion 207 of the wireless headset accessory 20, and the second power management module 205 in the wireless headset accessory 20 performs a charging process on the first power management module 108.
Correspondingly, when the audio file wireless headset is not adapted to the audio file wireless headset accessory, the third mating connection portion 110 is not electrically connected to the seventh mating connection portion 206 of the wireless headset accessory 20, the fourth mating connection portion 111 is not electrically connected to the eighth mating connection portion 207 of the wireless headset accessory 20, and the wireless headset 10 operates according to the existing operating mode of the wireless headset.
In this embodiment, in case that the user places the wireless headset in the wireless headset accessory, i.e. the wireless headset is fitted with the audio file wireless headset accessory, the third mating connection portion of the wireless headset is electrically connected with the seventh mating connection portion of the wireless headset accessory, and the fourth mating connection portion of the wireless headset is electrically connected with the eighth mating connection portion of the wireless headset accessory. Because the seventh matching connection part of the wireless earphone accessory is the power output end of the second power management module of the wireless earphone accessory and the eighth matching connection part of the wireless earphone accessory is the grounding end of the second power management module of the wireless earphone accessory, under the condition that the wireless earphone is matched with the audio file wireless earphone accessory, the second power management module of the wireless earphone accessory can serve as charging equipment and the wireless earphone can serve as electric equipment. At this time, the second power management module can perform charging processing on the first power management module, so that charging of the first power supply in the wireless headset is achieved. Thus, although the small size of the wireless headset results in poor endurance of the first power supply in the wireless headset, the wireless headset accessory can serve as a charging device to charge the first power supply, which can improve the endurance of the first power supply.
It should be noted that the second power management module of the wireless headset accessory includes an LDO (low drop out regulator), a DCDC voltage reduction circuit, and the like, and can control the output current and voltage, so that the second power management module can realize safe charging of the wireless headset.
On the basis of any of the above embodiments, as shown in fig. 5, the first sound-emitting unit 107 includes a first operational amplifier 1071 and a first sound-emitting element 1072. An input end of the first operational amplifier 1071 serves as an input end of the first sound emitting unit 107, and is electrically connected to a second output end of the digital-to-analog converter 106. The output terminal of the first operational amplifier 1071 is electrically connected to the input terminal of the first sound emitting element 1072.
In the embodiment of the present application, the first operational amplifier 1071 amplifies the analog audio file output by the digital-to-analog converter 106, so that the amplified audio file can drive the first sound-emitting device 1072 to emit sound. The first sound-emitting element 1072 is typically a speaker.
In the embodiment of the present application, when the micro processing unit 104 controls the first sound emitting unit 107 to power down, the following steps may be specifically performed: the first operational amplifier 1071 and/or the first sound emitting element 1072 in the first sound emitting unit 107 are controlled to be powered down. When the first operational amplifier 1071 and the first sound emitting element 1072 in the first sound emitting unit 107 are controlled to be powered down, the power consumption of the wireless headset 10 can be reduced.
The embodiment of the application also provides a wireless headset accessory 20. As shown in fig. 6, the wireless headset accessory 20 includes a second sound emitting unit 201, an interrupt circuit 202, a fifth mating connection 203 and a sixth mating connection 204 provided on the housing of the wireless headset accessory 20. Illustratively, the two metal mating connections may be embodied in the form of gold fingers, and may also be embodied in the form of metal contacts.
Wherein, the input end of the second sound generating unit 201 is electrically connected with the fifth matching connection part 203; the output terminal of the interrupt circuit 202 is electrically connected to the sixth mating connection 204.
