Description
本發明是有關於一種藍芽耳機，特別是指一種具有省電機制的藍芽耳機。The invention relates to a Bluetooth headset, in particular to a Bluetooth headset with a power saving mechanism.
現代無線電通訊發展迅速，特別是藍芽(Bluetooth)這類低功率的短距離無線傳輸被廣泛的應用於各種生活中會接觸到的電子產品，諸如鍵盤、滑鼠與手機等等，只要內建有藍芽晶片，就可以與相對應的電子裝置配對，並且進行無線傳輸。Modern radio communications are developing rapidly, especially low-power short-range wireless transmissions such as Bluetooth, which are widely used in a variety of electronic products that are exposed to life, such as keyboards, mice, and mobile phones, as long as they are built-in. With a Bluetooth chip, it can be paired with the corresponding electronic device and wirelessly transmitted.
在上述應用中，藍芽耳機為藍芽傳輸技術中最常見的應用之一。藍芽耳機能讓使用者在無法拿起話筒接聽電話的情況下，直接戴著藍芽耳機通話。習知的藍芽耳機是以充電電池作為其供電的來源，並且為了節省電池的電力會在滿足某些條件時切換成待機模式(standby mode)。參閱圖1，步驟911中，當藍芽耳機未接收到訊號(例如切斷通話時)，並且經過一段預設的時間後，則會進行步驟912，自動切換成待機模式，以節省電源延長可使用的時間。利用上述省電手段，以Nokia BH-902型號的藍芽耳機為例，電池充滿電的狀況下，其待機時間可長達110個鐘頭，而通話時間約8個鐘頭。Among the above applications, Bluetooth headset is one of the most common applications in Bluetooth transmission technology. The Bluetooth headset allows the user to directly talk to the Bluetooth headset without being able to pick up the handset to answer the call. Conventional Bluetooth headsets use rechargeable batteries as their source of power, and in order to conserve battery power, they switch to a standby mode when certain conditions are met. Referring to FIG. 1, in step 911, when the Bluetooth headset does not receive a signal (for example, when the call is disconnected), and after a predetermined period of time, step 912 is performed to automatically switch to the standby mode to save power extension. The time used. Taking the above-mentioned power-saving means, taking the Nokia BH-902 model of the Bluetooth headset as an example, when the battery is fully charged, the standby time can be as long as 110 hours, and the talk time is about 8 hours.
然而，當使用者未使用耳機(即未佩帶藍芽耳機)的時候，若未順手手動關閉訊號源裝置(如MP3播放器)的電源，就算提供了上述省電手段，由於還是會有訊號持續在傳輸，導致藍芽耳機誤判仍在使用中，藍芽耳機不會切換成待機模式，很快的，電力會被消耗殆盡。However, when the user does not use the headset (ie, does not wear the Bluetooth headset), if the power supply of the source device (such as an MP3 player) is not manually turned off, the power saving means is provided, since the signal continues to be continued. In the transmission, the Bluetooth headset error is still in use, the Bluetooth headset will not switch to standby mode, and soon, the power will be exhausted.
因此，本發明之目的，即在提供一種可用以偵測使用者穿脫動作，以判斷耳機的使用狀態，而適時節能的藍芽裝置。Therefore, the object of the present invention is to provide a Bluetooth device that can be used to detect a user's wear and tear action to determine the state of use of the earphone, and to save energy in a timely manner.

有關本發明之前述及其他技術內容、特點與功效，在以下配合參考圖式之一個較佳實施例的詳細說明中，將可清楚的呈現。The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.
參閱圖2及圖3，圖2是本發明藍芽耳機10之較佳實施例的使用示意圖，圖3則為本實施例的電路方塊示意圖。本發明藍芽耳機10是一種可以與一電子裝置80配對並且進行無線資訊傳輸的藍芽耳機10，而在以下的示例中，電子裝置80是一內建有藍芽模組的手機或播放器等等，可以撥放音樂以及撥打電話，但並不以本實施例為限，亦可以為具有藍芽傳輸功能的智慧型電子裝置。2 and FIG. 3, FIG. 2 is a schematic diagram of the use of the preferred embodiment of the Bluetooth headset 10 of the present invention, and FIG. 3 is a block diagram of the circuit of the present embodiment. The Bluetooth headset 10 of the present invention is a Bluetooth headset 10 that can be paired with an electronic device 80 and transmits wireless information. In the following example, the electronic device 80 is a mobile phone or player with a Bluetooth module built therein. And so on, you can play music and make calls, but it is not limited to this embodiment, and it can also be a smart electronic device with Bluetooth transmission function.
該藍芽耳機10包含一用以供穿戴於一使用者的耳殼90(假想線所示)上的殼體11、設於殼體11中的藍芽模組12、與藍芽模組12電連接的一揚聲模組13及一收音模組14、一處理單元16、與該處理單元16電連接的一使用狀態判斷單元15，以及可被充電且供應上述電路模組所需電能的電源電源供應模組17。這其中，殼體11所具有的外型相對於頭部或耳殼90，而實現穿戴藍芽裝置10。The Bluetooth headset 10 includes a housing 11 for being worn on a user's ear shell 90 (shown as an imaginary line), a Bluetooth module 12 disposed in the housing 11, and a Bluetooth module 12 A speaker module 13 and a sound module 14 electrically connected, a processing unit 16, a use state judging unit 15 electrically connected to the processing unit 16, and a power supply that can be charged and supplied with the circuit module Power supply module 17. Among them, the housing 11 has an outer shape with respect to the head or the ear shell 90, and the wearing of the Bluetooth device 10 is achieved.
該藍芽模組12是用以與該電子裝置80配對，並且在必要的時候，可進行無線傳輸；該揚聲模組13是用以將該藍芽模組12由該電子裝置80所接收到的一第一聲音訊號轉換成聲音，以達到播放效果；該收音模組13則是用以擷取使用者的聲音，並將聲音轉換成一第二聲音訊號，然後透過該藍芽模組12輸出予該電子裝置80。舉一實例幫助說明：當使用者把藍芽耳機10與電子裝置80透過彼此的藍芽模組12與藍芽模組81配對，並且進行撥打電話的動作，電子裝置80所接收到遠端傳來的第一聲音訊號會傳送給該藍芽模組12，再經由揚聲模組13將此第一聲音訊號解譯，並撥放出對應的聲音讓使用者聽，而當使用者講話時，收音模組14會擷取使用者講的話，並且轉譯為第二聲音訊號予該藍芽模組12，再傳輸給電子裝置80發送出去。The Bluetooth module 12 is configured to be paired with the electronic device 80 and, if necessary, wirelessly transmitted; the speaker module 13 is configured to receive the Bluetooth module 12 from the electronic device 80. The first sound signal is converted into a sound to achieve a playback effect; the sound module 13 is used to capture the user's voice, and convert the sound into a second sound signal, and then through the Bluetooth module 12 Output to the electronic device 80. An example helps to explain that when the user pairs the Bluetooth headset 10 and the electronic device 80 with each other through the Bluetooth module 12 and the Bluetooth module 81, and performs a call making action, the electronic device 80 receives the remote transmission. The first sound signal is transmitted to the Bluetooth module 12, and the first sound signal is interpreted by the speaker module 13, and the corresponding sound is played for the user to listen to, and when the user speaks, The radio module 14 will retrieve the words spoken by the user and translate the second audio signal to the Bluetooth module 12, and then transmit it to the electronic device 80 for transmission.
由於藍芽耳機10通常都是佩帶在人體的頭部或耳殼90上，以利將聲音傳入耳朵內部。換言之，當藍芽耳機10遠離人體時，特別是遠離人體的耳殼90或鄰近耳殼90的部位，通常都代表使用者暫時不使用藍芽耳機10。既然藍芽耳機10遠離人體時可代表不再使用，那麼只要藍芽耳機10遠離人體就切換成節能狀態，確實能夠不影響正常使用，又能達到省電目的。相反地，只要藍芽耳機10鄰近人體時，通常都代表使用者要使用藍芽耳機10。Since the Bluetooth headset 10 is usually worn on the head or ear shell 90 of the human body, the sound is transmitted to the inside of the ear. In other words, when the Bluetooth headset 10 is remote from the human body, particularly away from the ear shell 90 of the human body or a portion adjacent to the ear shell 90, it is generally representative that the user does not temporarily use the Bluetooth headset 10. Since the Bluetooth headset 10 is no longer used when it is far away from the human body, as long as the Bluetooth headset 10 is switched away from the human body, it is switched to an energy-saving state, and it can really achieve the purpose of power saving without affecting normal use. Conversely, as long as the Bluetooth headset 10 is adjacent to the human body, it typically represents the user using the Bluetooth headset 10.
為了偵測藍芽耳機10遠離或鄰近人體，可利用一組感應元件(即訊號發射元件與相對的接收元件)來實現。換言之，在藍芽耳機10遠離或鄰近人體時，相對地定義對訊號發射元件與接收元件之間所照成的特性值變化，就可判斷出藍芽耳機10的使用狀態(即是否被佩帶)，而決定藍芽耳機10處於節能狀態或工作狀態。訊號發射元件與接收元件之間所傳送的訊號可為超音波、雷射光、紅外線或電子/電磁訊號等等。為了方便說明起見，底下僅以電子訊號為範例，但並不以本實施例為限，其它能夠偵測出藍芽耳機10遠離或鄰近人體的手段均為本發明所欲保護的範疇。In order to detect that the Bluetooth headset 10 is remote from or adjacent to the human body, a set of inductive components (ie, signal emitting components and opposing receiving components) can be utilized. In other words, when the Bluetooth headset 10 is remote from or adjacent to the human body, the change in the characteristic value between the signal transmitting component and the receiving component is relatively defined, and the state of use of the Bluetooth headset 10 (ie, whether it is worn) can be determined. And it is decided that the Bluetooth headset 10 is in a power saving state or a working state. The signal transmitted between the signal transmitting component and the receiving component may be ultrasonic, laser light, infrared or electronic/electromagnetic signals, and the like. For convenience of description, only the electronic signal is taken as an example, but it is not limited to this embodiment. Other means capable of detecting that the Bluetooth headset 10 is away from or adjacent to the human body are all areas to be protected by the present invention.
配合參閱圖4，為了偵測藍芽耳機10遠離或鄰近人體(特別是耳殼90)，使用狀態判斷單元15具有一感應元件(例如：一對導體221)及一與該感應元件電連接的感測電路222。該感測電路222是用以感測該感應元件的一特性值變化，並對應該特性值變化選擇輸出節能指令或一工作指令予處理單元16，使該處理單元16控制該藍芽耳機10切換成節能狀態或工作狀態。在本實施例中，使用狀態判斷單元15實為一電容感測模組，而感應元件是兩個設於殼體11中的導體221，並與感測電路222電連接；一對導體221是彼此相間隔地設置於該殼體11內，並沿著殼體11的內表面設置，且其間存在有電流通過所產生的一原生電容91(假想線所示)。具體來說，當使用者的皮膚(特別是耳殼90的皮膚)接近此一對導體221時，由於人體也可視為導體，因此會分別與此一對導體221生成耦合電容92(假想線所示)。此時感測電路222所測得的電容值不僅只有原生電容91，還要加上原生電容91並聯的兩個耦合電容92，因此，原生電容91與二耦合電容92加總後的電容值，使得感測電路222感測到不同於初始電容值的電容值，而產生感應元件的特性值變化。Referring to FIG. 4, in order to detect that the Bluetooth headset 10 is away from or adjacent to the human body (especially the ear shell 90), the use state judging unit 15 has an inductive component (for example, a pair of conductors 221) and an electrical connection with the inductive component. Sensing circuit 222. The sensing circuit 222 is configured to sense a characteristic value change of the sensing element, and select an output power saving instruction or a work instruction to the processing unit 16 for the characteristic value change, so that the processing unit 16 controls the Bluetooth headset 10 to switch. Into a power saving state or working state. In this embodiment, the use state determining unit 15 is actually a capacitive sensing module, and the sensing elements are two conductors 221 disposed in the housing 11 and electrically connected to the sensing circuit 222; the pair of conductors 221 are They are disposed in the housing 11 at intervals and are disposed along the inner surface of the housing 11 with a primary capacitor 91 (shown by an imaginary line) generated by the passage of current. Specifically, when the skin of the user (especially the skin of the ear shell 90) approaches the pair of conductors 221, since the human body can also be regarded as a conductor, a coupling capacitor 92 is generated with the pair of conductors 221, respectively (hypothetical line Show). At this time, the capacitance value measured by the sensing circuit 222 is not only the primary capacitor 91, but also the two coupling capacitors 92 in which the primary capacitor 91 is connected in parallel. Therefore, the capacitance values of the primary capacitor 91 and the two coupling capacitors 92 are added together. The sensing circuit 222 senses a capacitance value different from the initial capacitance value to generate a characteristic value change of the sensing element.
利用上述原理，該感測電路222會當一對導體221鄰近使用者的耳殼90時，該感測電路222感測到導體221間的電容值上升而輸出工作指令予該處理單元16。相反地，當一對導體221遠離耳殼90時，感測電路222感測到一對導體221間的電容值下降而輸出該節能指令予該處理單元16。值得一提的是，感測電路222為具有弛張振盪器(Relaxation Oscillator)與微形處理器等的感測電路222，此應為熟悉此技藝者所通知，且感測電路222的種類與運作細節亦非本發明之重點，於此不多贅述。需要注意的是，本發明所使用的使用狀態判斷單元15並不一定要以本實施例測量電容值的樣態為限，亦可以為紅外線感應式或者雷射光感應式等，詳細技術內容可參閱中華民國專利第M280061公告號，在此不予贅述。With the above principle, the sensing circuit 222 senses that the capacitance value between the conductors 221 rises and outputs a work command to the processing unit 16 when the pair of conductors 221 are adjacent to the ear shell 90 of the user. Conversely, when the pair of conductors 221 are away from the ear shell 90, the sensing circuit 222 senses a decrease in the capacitance value between the pair of conductors 221 and outputs the power saving command to the processing unit 16. It is worth mentioning that the sensing circuit 222 is a sensing circuit 222 having a Relaxation Oscillator and a microprocessor, etc., which should be notified by those skilled in the art, and the type and operation of the sensing circuit 222. The details are also not the focus of the present invention, and will not be described here. It should be noted that the usage state judging unit 15 used in the present invention is not necessarily limited to the state in which the capacitance value is measured in the embodiment, and may be an infrared inductive or a laser inductive type. For details, refer to the technical content. The Republic of China Patent No. M280061 is not to be repeated here.
該處理單元16於接收到前段所述的工作指令後，會控制藍芽耳機10，令該藍芽耳機10切換成工作狀態，並於接收到該節能指令後令該藍芽耳機10切換成節能狀態。在本實施例中，處於工作狀態的藍芽耳機10是在各個電路單元皆以工作電能(main power)運作，故對於電源供應模組17的負擔較大，會快速地消耗所儲存的電能。相對地，處於節能狀態的藍芽耳機10是在切換成待機模式，而關閉某些電路運作，因此較為省電。值得一提的是，依不同應用，藍芽耳機10設計者可以選擇設計成，接到節能指令後，切換成省電模式或直接關機等可以節省能源的狀態，非以本實施例為限。After receiving the work instruction described in the previous paragraph, the processing unit 16 controls the Bluetooth headset 10 to switch the Bluetooth headset 10 into an active state, and switches the Bluetooth headset 10 to energy saving after receiving the power saving command. status. In the present embodiment, the Bluetooth headset 10 in the working state operates in the main power of each circuit unit, so that the load on the power supply module 17 is large, and the stored power is quickly consumed. In contrast, the Bluetooth headset 10 in the energy-saving state is switched to the standby mode, and some circuits are turned off, thereby saving power. It is worth mentioning that, depending on the application, the designer of the Bluetooth headset 10 can choose to design, after receiving the energy-saving instruction, switch to the power-saving mode or directly shut down, etc., which can save energy, not limited to this embodiment.

The remote control module 18 includes a function option button 181 disposed on the housing 11, and a separate function and function button 181. And the multiplex unit 182 electrically connected to the processing unit 16; the function option button 181 of the embodiment can be used for the user to switch between a first switching position and a second switching position, each of which represents a specific The function option, the multiplex unit 182 respectively generates a first signal or a second signal to the processing unit 16 according to the first switching position or the second switching position selected by the user, and the processing unit 16 receives the In the work instruction, in addition to switching the Bluetooth headset 10 to the working state, the corresponding signal is switched to a specific first action, and when the power saving command is received, the Bluetooth headset 10 is further adapted to a different signal. Perform a specific second action and then switch to the energy saving state. In this embodiment, when the user selects the first switching position, the first action is to make the electronic device 80 make a call through the Bluetooth module 12, and the second action is to end the call, when the user selects In the second switching position, the first action is to cause the electronic device 80 to play music through the Bluetooth module 12, and the second action is to stop playing music.

After the Bluetooth headset 10 is paired with the Bluetooth module 81 of the electronic device 80 through the Bluetooth module 12, first step 51 is performed, and the user dials the function option button 181 on the housing 11 by using the function option. The button 181 is toggled to the first position or the second position to select a desired function option, and the multiplex unit 182 respectively generates a first signal or a second signal according to the selected first switching position or the second switching position. The processing unit 16 is pre-processed. If the first switching position is selected in step 51, then step 52 is performed to sense whether the Bluetooth headset 10 is worn. When the user wears, the sensing circuit 222 of the usage state determining unit 15 senses the conductor 221.

When the user removes, the sensing circuit 222 senses a decrease in the capacitance between the pair of conductors 221 and outputs the power saving command to the processing unit 16. The processing unit 16 performs steps according to the first signal and the power saving instruction. 55, causing the electronic device 80 to end the call and switch to the standby mode. If the second switching position is selected in step 51, the same step 53 as step 52 is performed. If, in step 53, the Bluetooth headset 10 is sensed to be worn, the processing unit 16 performs step 56. Switching to the working mode and causing the electronic device 80 to play music, if it is sensed that the Bluetooth headset 10 is removed, the processing unit 16 performs step 57 to cause the electronic device 80 to stop playing music and switch to the standby mode.
本發明之功效在於，利用使用狀態判斷單元15偵測藍芽耳機10是否被使用者佩帶，來判斷藍芽耳機10的使用與否以決定是否要切換成待機模式，此判斷方式相較於過去利用無線訊號的有無，不僅能夠更正確地判斷出藍芽耳機10是否正在被使用，並且在使用者脫下藍芽耳機10的瞬間，藍芽耳機10即能切換成待機模式，對比過去還需要等待一段時間才切換成待機模式，節省了更多的電能，另外對應穿脫藍芽耳機10的動作還可以產生許多操作上的動作，比方說撥打電話與掛斷電話、撥放音樂與停止音樂等等，更增加操作上的便利性。The effect of the present invention is to determine whether the Bluetooth headset 10 is used or not by using the state determination unit 15 to determine whether the Bluetooth headset 10 is used or not to determine whether to switch to the standby mode. By using the presence or absence of the wireless signal, not only can the Bluetooth headset 10 be used more correctly, but also when the user takes off the Bluetooth headset 10, the Bluetooth headset 10 can be switched to the standby mode. Waiting for a while before switching to standby mode saves more power. In addition, the action of wearing the Bluetooth headset 10 can also generate many operational actions, such as making a call and hanging up the phone, playing music and stopping the music. And so on, it increases the convenience of operation.
